Bespoke Hot Water and Heating, Celebrating 50 Years Of Excellence

For the past 50 years, Adveco Ltd has been the recognizable face of A.O. Smith in the UK. As with so many businesses, it started with a simple idea from founder Daniel O’Sullivan to improve efficiency and save costs, two core ideals that remain at the heart of everything the business still does today. In 1971, the focus was to support the launderette industry by introducing a simple hot water application that utilized a glass-lined boiler and galvanized hot water storage tank. This unique approach helped to define the early days of the business and created a new market and new demands. The company was later recognised by BSRIA as the instigator of direct gas-fired water heaters in the UK. Today, the company is one of the trusted specialist providers of low-carbon, bespoke hot water and heating to the building services industry.

The first ever UK installed A.O. Smith glass line boiler

Adveco operates across the commercial built environment, working with consultants, specifiers, and designers, providing informed support and partnership to design and deliver systems optimised to be highly efficient and cost-effective. Contractors gain a single, versatile, specialist sales resource that ensures delivery of the most cost-effective system. Facility managers are supported through product remote monitoring, technical support, warranty, and maintenance service to ensure system longevity and help realise a low total cost of ownership.

As a result, our systems can be found across the country, from prestige city sites to university and school accommodations, hospitals and care homes, supermarkets, sports stadia, hotels, restaurants and leisure facilities of all sizes. It is pretty much guaranteed you will have used bespoke hot water and heating from a system Adveco has designed, supplied, and maintains without ever realising it.

50 Years of Bespoke Hot Water Innovation

Daniel O’Sullivan and the sales team inspect the latest models from A.O.Smith

Founded as Advance Services (Sales) Ltd, that initial year defined much of the history of the business with a close partnership formed with the American based water heater manufacturer A.O. Smith. The company would quickly become A.O. Smith’s sole UK distributor, even though it had elsewhere opted for a multi-distributor approach. Here it had become clear that the success in the UK had stemmed from working with a focused single market entity, and the partnership was further ratified in 1998 when Advanced Services Sales Ltd became A.O. Smith’s sole official partner and under its new agreement started trading as A.O. Smith Water Products, and then latterly as A.O. Smith Water Heaters (Adveco AWP) Ltd.

Although Daniel retired in 2000, his son David O’Sullivan continued to grow the family business, maintaining its fierce independence and commitment to innovation. More than just offering distributions services, A.O. Smith Water Heaters had grown a wider reputation for its own in-house engineering capabilities, providing a wealth of knowledge for commercial hot water application design and post-installation service.

In 2015, Adveco Ltd. was established to further develop this capability, as well as providing complementary products to enhance the company’s offering. Operating as an independent sister company to A.O. Smith Water Heaters, Adveco has expanded in recent years, establishing European sales offices and continues its commitment to the design, supply, commissioning and full after-sales support and maintenance servicing, of more than 1,000 commercial boiler, hot water, and solar thermal systems every year.

More recently A.O. Smith has returned to its original multi-distributor model, although its own brand product ranges remain with Adveco / A.O. Smith Water Heaters in the UK. This process has given impetus to the modernization of the business. Though continuing to provide a full range of commercial gas and electric water heaters, boilers, and solar thermal systems from the A.O. Smith portfolio, Adveco is evolving to become a single point of contact for a wider range of commercial bespoke hot water and heating systems that address a market being redefined by the drive to sustainability and the target of Net Zero by 2050.

RP MD Boilers.

MD Floor Standing Boiler

We continue to see increasing demand for near-instantaneous and instantaneous water heating across a variety of projects and are constantly exploring ways to meet this often technical challenge for commercial applications. Within those hot water applications, the highly efficient A.O. Smith BFC Cyclone and Innovo are always a popular choice for commercial projects requiring hot water. The MD range of floor standing condensing gas boilers, which were highly commended in the HVR Awards on launch, have also proved to be very popular for commercial heating, boasting a seven-year parts and maintenance warranty which we are able to offer due to the strong, corrosion-resistant titanium steel construction and smart balancing of the pre-stacked heat exchangers.

Despite the hyperbole, gas remains, at least for the time being, a core element for commercial systems. Familiar, well understood and extremely cost-effective, it remains an important part of the product portfolio for delivery of domestic hot water (DHW) applications and heating.  Adveco’s DHW offering has extended with a range of new stainless steel condensing water heaters to address soft water areas in the UK, alongside a range of stainless-steel cylinders, packaged plate heat exchangers and electric immersion kits which enables greater use of clean electricity for primary and backup heating of water across a range of bespoke tanks. Although we would characterize ourselves as hot water specialists, we can still address the specialist needs of commercial-scale heating with our ranges of floor-standing and wall-hung gas boilers (MD), carbon steel heating buffers (MSS) and thermal storage (MST).

A More Sustainable Future

RP Solar thermal.

Adveco solar thermal with drainback technology

Perhaps most exciting, has been the work to develop systems that are capable of better integrating low carbon and renewable technologies. In 2009, Adveco committed to development in this space with the introduction of its first Solar Thermal systems, working in partnership to develop critical drainback technologies that addressed the massively costly issue of stagnating solar fluid in panels and pipework. There is no doubt in our minds that as the demands for lower carbon applications grow, a combination of Solar Thermal and traditional gas will see a resurgence. But there is a degree of complexity that needs to be recognised and that is where specialist knowledge pays dividends when investing in both new and refurbished properties. Solar Thermal also has a role to play in more advanced hybrid systems that will be more dependent on electricity, the use of heat pumps and heat recovery technologies.

FPi32 commercial Air Source Heat Pumps (ASHP).

FPi32 Air Source Heat Pump

In recent years, Adveco has struck several exclusive manufacturing partnerships to develop air source heat pump (ASHP) technology and products expressly for the generation of preheat for DHW systems. This is necessary to address both building regulations in the UK and our varied Northern European climate.  The fruits of those partnerships have been the launch of the FPi range of Air Source Heat Pumps (ASHP) in 2019, quickly followed by the introduction of the L70 heat pump for larger-scale projects. This year the FPi Range was completely revised with the introduction of a new system based on the more environmentally friendly R32 refrigerant which delivers considerable advances over its predecessors. This development programme continues at pace as we hone designs that help meet the high-temperature demands of commercial DHW. Our development work also includes the creation of the HVR Awards recognised HR001 boxed heat recovery system which was designed and manufactured in-house to support businesses making regular daily use of commercial-grade chiller and freezer units. Commercial systems offer a range of opportunities for heat recovery, essentially gaining ‘free heat’ that can be used to offset energy demands and help reduce carbon emissions from daily operations. Adding heat recovery into your sustainability mix is frankly a no brainer and we continue to explore opportunities for its application within commercial systems.

Packaged Plant Rooms.

Low carbon hot water systems in an Adveco Packaged Plant Room

Bringing all these varied elements together is Adveco’s packaged plant room offering, a bespoke hot water and heating system build that leverages all the advantages of offsite construction. Pre-fabrication is a tried and tested way of bringing mechanical and electrical systems to a live construction site, countering the challenges of complexity, limited space, limited time, and the need to work around other contractors. The concerns over post-Brexit/Covid rising costs, construction projects struggling to attain raw materials as well as a shortfall of experience on-site cannot be discounted. Offsite construction is therefore a great way to address these potential fears.  It just makes things on site much easier and crucially helps to accelerates those all-important project timelines which in turn can help offset other unforeseen project costs.

Packaged plant rooms can almost be treated as a microcosm of our work, a large proportion of which we create as bespoke applications and that includes our smart control systems. So, for Adveco, almost all our projects begin with application design. Without doubt, the rapid changes to legislation relating to efficiency and emissions as we move towards Net Zero by 2050 is having far-reaching implications for our industry. The challenge, certainly for commercial buildings, is to design, supply and then monitor a system for its full lifecycle to ensure the various elements of a system work together, not against each other. The problem is that we are increasingly seeing more cases of the wrong technology being used for the right application: from oversizing for the building, or failure to account for summer heating loads, to under-sizing solar buffer vessels and poorly executed combinations of renewables. Poor sizing has always been a key failure, driving up CAPEX and unnecessarily raising OPEX, but these more varied system design errors must be seen as a result of the rush to be environmentally friendly compounded by the confusion over what that really means in terms of practical technology choices. As an HVAC business, you simply cannot stand still, customers won’t allow for that, so being versatile in the ability to deliver bespoke, engineered systems, is becoming even more of an advantage for us as we look at the changing needs of customers, both in the short and long term. Our application design team provide professional support throughout all stages of a project, from selecting the pertinent product to meet a specific demand to complete system design.  All projects are meticulously sized by our in-house team of qualified industry professionals. This ensures that all applications receive a bespoke, cost-effective design that avoids the typical pitfalls described.

Looking Forward

All eyes are now on the 26th UN Climate Change Conference (COP26) and an expectation of greater clarity from the Government over how the commercial sector will be supported on the road to Net Zero. At Adveco, our approach is to be prepared for all options, whether the future of commercial heating and hot water in the UK will be designated all-electric, hydrogen/green gas, or a mix of the two. This continues to drive our exploration of new technologies and reiterates the advantages of being independent. It enables us to create these critical technical partnerships that allow us to be quick on the uptake of new, or more relevant technologies, whilst continuing to leverage our own deep technical experience. In the near term, we will be further developing our portfolio of heat pumps for commercial applications, as well as designing new hybrid systems that take best advantage of this and other technology. We also see the huge, and cost-effective potential for the large scale roll-out of hydrogen to the commercial sector. All this will require a greater demand for complete system design of which we have deep experience providing bespoke hot water and heating. Ultimately, we come back to the earliest tenet of the company, an unbeatable focus on commercial hot water systems. We already have a strong offering, whether gas and solar, or all-electric with heat pumps, and see this consultancy work, especially for D&B contractors, driving our future growth out beyond 2050.

Adveco Named Double Finalist in 2021 HVR Awards

  • Packaged e32 Hot Water Systems named finalist in the HVR 2021 Commercial Heating Product of the Year category
  • FPI32 named finalist in the HVR 2021 Heat Pump Product of the Year category

Hot water and heating specialist Adveco is proud to announce it has been named a finalist in two key categories in the 2021 Heating & Ventilation Review (HVR) Awards. Adveco’s Packaged e32 Hot Water Systems has been named a finalist in the HVR 2021 Commercial Heating Product of the Year category, while the FPi32 range of air source heat pumps (ASHP) was named a finalist in the Heat Pump Product of the Year category.

The HVR Awards celebrate the products, brands, businesses and people that have led the way with their innovation and unrivalled levels of excellence, inducting them into the prestigious HVR Awards ‘Hall of Flame’.

Bill Sinclair, technical director, Adveco, said:

“Both products take full advantage of using R32 refrigerant to take us toward responsible, sustainable systems that deliver business-critical hot water without harming the environment.”

The Adveco FPi32 is a range of compact monobloc design 6, 9 & 12 kW air to water heat pumps providing hot water at 55°C, or higher in hybrid systems. The FPi32 range leverages R32 refrigerant to enhance year-round efficiency (COP as high as 5.23) while reducing the global warming potential (GWP), thereby lowing environmental impact.

The FPi32-9’s compact monobloc form factor also makes it perfect for integration into Adveco’s Packaged e32-Hot Water System.  A complete, highly efficient, low carbon, all-electric packaged water heating system that uses the FPi32-9 to provide preheat for reliable high-temperature water supplied in a convenient GRP housing.

The air to water heat pump provides the system preheat from 10°C to 50°C, supplying 70% of the DHW load. Offsetting 70% of the energy requirement means the Packaged e32-Hot Water System can demonstrate a 47% reduction in energy demands and CO² emissions for the same output of 500,000 litres of hot water each year when compared with a similar direct electric-only system. The reduced energy demand also means operational savings can be added to the capital savings secured during the design, supply, and installation phases.

The system is also ground-breaking in the application of a completely new specification that lowers the heat intensity, without detrimental effect to the demands for hot water, meaning the Packaged e32-Hot Water System is also more resistant to scale, reducing maintenance demands.

“By unifying innovative, low carbon technology with excellence in application design, all provisioned under an offsite construction model, we can bring a wealth of new advantages for consultants, contractors, installers and owner-operators. FPi32 and our pre-sized e32-Hot Water System not only go a long way towards helping businesses meet carbon targets this decade but also help keep running costs low,”

adds Bill.

The 2021 HVR Awards winners will be announced in a virtual presentation on Oct 7th. For more details visit the HVR Awards website.

adds David.

The winners will be announced this November and we wish all the finalists the very best of luck.

Building Regulations for Commercial Hot Water

Committed to raising the energy performance of buildings, the government has now concluded the second of a two-stage consultation on the Building Regulations (Conservation of fuel and power) for England & Wales. This consultation proposes changes to Part L to provide a pathway to highly efficient non-domestic buildings which are zero carbon ready, better for the environment and fit for the future.

These new standards are due to be released in 2025 but will drive interim measures over the next four years for non-domestic buildings as outlined in the Building Regulations: Approved Documents L and F.

These measures outline the expected move away from fossil fuels to low carbon technology for heating and domestic hot water (DHW) and set a more rapid timeline. There is no doubt these new measures will ultimately represent a seismic shift in thinking when it comes to commercial hot water and heating applications, but a buffer has been built in to allow for the development of systems that are necessarily more complex than would be seen in domestic settings. This brings considerable opportunities for developers and specifiers willing to consider both existing and new technologies in order to deliver compliant applications in the next five years.

Whilst a fabric first approach is encouraged, low carbon technologies are being emphasised. This means heat pumps for the broad majority of DHW applications where there is a low heat demand. For commercial properties where there is typically a high heat demand, gas is still allowed while the industry works to develop suitable alternatives.

Hot Water Systems Under Part L For Non-Domestic Buildings

For our current purposes, while we will focus our attention on the provision of DHW for new build non-residential projects. Before we cover that, it is worth noting some of the general requirements for the wider heating systems as these must still be adhered to as part of the overall thermal efficiency of a DHW system.

Each new fixed building service, whether in a new or existing building, must meet the legislated values set out for efficiency. Replacement fixed services must be at least as efficient, either using the same or a different fuel as the service being replaced with matching or preferably better seasonal efficiency.

If moving over to a new fuel system, such as oil or LPG to natural gas, it should not produce more CO2 emissions nor more primary energy per kWh of heat than the appliance being replaced. If ageing renewables such as wind or solar are being replaced the electrical output must be at least that of the original installation, except where it can be demonstrated that a smaller system would be more appropriate or effective. And if work extends or provides new fixed building services energy meters will need to be installed.

When specifying a DHW system, sizing should be based on the anticipated demand of the building (based on BS EN 12831-3). The regulations demand systems not be “significantly oversized,” but we would argue any oversizing will have a negative impact on the efficiency and operational costs of a DHW system. So accurate sizing is critical in terms of delivering an optimal thermal efficiency assessment. That assessment will include the heat generator and any integral storage vessel but will exclude all secondary pipework, fans, pumps, diverter valves, solenoids, actuator and supplementary storage vessels from the calculations.

As a guide the minimum thermal efficiencies for natural gas-based DHW systems, based on gross seasonal efficiency of the heat generator are:

91% Direct fired for a new building with >30kW output*
91% Direct fired for a new building with <30kW output*
91% Boiler efficiency for indirect-fired systems in new & existing buildings
100% assumed Electrically heated new & existing buildings

Adveco carries of range of direct-fired condensing glass-lined water heaters such as the AO Smith BFC Cyclone (97% efficient) and Innovo (98% efficient), as well as an expanding range of stainless steel boilers and water heaters, such as the MD/AD which leverage advanced burner control to drive efficiency even higher (106%). This helps guarantee regulations are met and provides a safety net should regulations tighten in the future.

As with the broader regulations relating to space heating, controls form a necessary element of the new Part L regulations for combustion heated DHW systems. These all must incorporate timer control (independent of space heating circuits) and electronic temperature control.

Additionally, regulations call for fully pumped circulation where compatible with the heat generator for primary hot water circuits. Automatic thermostatic control to shut off the burner/primary heat supply when the desired water temperature is reached, and primary flow if the system temperature is too high for all direct-fired circulator systems, direct-fired storage systems and indirect-fired systems. Direct-fired continuous flow systems should include a heat exchanger flow sensor to control outlet temperatures and detect insufficient flow with burner/heat input shut off. A high limit thermostat is also required to shut off the primary flow if the system temperature is too high.

Point-of-use, local and centralised domestic hot water systems should have automatic thermostatic control to interrupt the electrical supply when the setpoint storage temperature is reached or system temperature gets too high. If there is an over-temperature trip manual reset should be possible.

Local and centralised DHW systems should have both a 7-day time control and the facility to boost the temperature by using an immersion heater in the cylinder.

Instantaneous water heaters should include a flow sensor to control the rate of flow through the heat exchanger. If the sensor detects insufficient flow, it should shut off the electrical input. Plus, a high limit thermostat is required to shut off the primary flow if the system temperature is too high.

Alongside gas, solar thermal is likely to be applied in the notional building unless heat pumps meet 100% of the actual building’s demand. Solar has been used in calculations in the past to overcome the poor fabric performance of a building. But, given the broad majority of heat pumps are currently used for preheat on commercial DHW applications, at most offsetting 70% of the energy demanded, solar thermal has a valid role to play and it’s a proven sustainable technology. Our expectations are for commercial DHW systems to continue in a familiar manner for the near to mid-term, with gas appliances used to provide cost-effective supply, especially during grid peak hours. Heat pumps and/or solar thermal will be deployed to provide preheat to that system.  As efficiencies improve and higher water temperature (more than 60°C) are achieved through heat pumps we see gas appliances slowly being phased out unless they can be replaced with green gas (hydrogen) alternatives. This naturally leads to the provisioning of hybrid systems for the coming decade, optimising a mix of current technologies that address the latest regulations, reduce emissions and crucially deliver value for money with lower operational costs.

One final observation on the implication for the specification and installation of commercial DHW relates to completion requirements. Part L tightens the commissioning requirements to reduce the gaps in performance over design and is intended to deliver improved project handover with accurate energy usage predictions. As a result, we can expect to see revisions of commissioning processes across the industry to help streamline delivery and speed up handover, crucial if government roll-out targets for low carbon technologies to achieve Net Zero by 2050 are to be met and superseded by commercial organisations.

Will Hydrogen be the move we need towards Net Zero?

With emissions difficult to fully eliminate from certain parts of the economy, most experts agree that green Hydrogen is essential to meeting the goals of Net Zero by 2050. Urging the Government to publish its Hydrogen Strategy sooner rather than later, it has confirmed support of the crossover in a domestic setting but is yet to announce a defined strategy for the commercial industries. So, will the UK turn to Hydrogen use everywhere?

What are Blue and Green Hydrogen?

Blue Hydrogen:

is when natural gas is split into hydrogen and carbon dioxide (CO2) with the use of either Auto Thermal Reforming (ATR) or Steam Methane Reforming (SMR).  The CO2 is captured and then stored, reducing emissions into the atmosphere reducing environmental impacts on the planet.

Green Hydrogen:

Is hydrogen fuel that is created with the use of renewable energy in place of fossil fuels. It has potential for manufacturing, transportation and much more, with clean power and water the only by-product.

The advantages of switching to Blue and Green Hydrogen

Hydrogen has many advantages as it is abundant and supply is near limitless. It can be used on site of production and/or hydrogen is capable of being transported elsewhere if required. The environmental advantages of hydrogen are it contains almost three times the energy of fossil fuel use, therefore less will be needed to do the equivalent work.

Another advantage is hydrogen, unlike current methods, can be produced from excess renewable energies, and wherever there is water and electricity to generate more electricity or heat, for longer periods of time, in much larger quantities.

The disadvantages of switching to Blue and Green Hydrogen

Highly flammable in concentration and light compared to other fuels, as with other commonly used fuels, such as natural gas and propane, Hydrogen needs to be handled with caution. Hydrogen’s lightness does mean that it will disperse quickly into the atmosphere should there be a leak, reducing the danger of ignition. This is particularly important if hydrogen is to be transported via the existing gas infrastructure. Hydrogen moves differently from natural gas and is more likely to escape from older pipework than natural gas, so there will be concerns over the safety of a network seen to be leaking hydrogen.

In addition, the capturing process will increase the methane and propane burden so hydrogen production may not be as environmentally friendly as many may be lead to believe as

Environmentalists opposing the switch to Hydrogen

Environmentalists have openly been warning the Government to ignore the “hype” of Hydrogen to provide heat within the UK. As the Government pushes for its’ Net Zero goal, proposed plans suggest for new natural gas boilers (domestic) to be phased out in the foreseeable future and replaced with Hydrogen-ready alternatives. But environmentalists are pushing for electrical heat pumps to be endorsed over Hydrogen, which they believe is not environmentally benign.

Hydrogen for commercial use

With around half of the UK’s energy consumption being used for heating and contributing towards a third of greenhouse gas emissions, reducing carbon from the heating and hot water industry supply is a key issue for the UK to meet the plans set out for Net Zero by 2050.

Hydrogen has seen lots of traction over the years as a replacement for fossil-based gasses, converting the existing gas infrastructure to be used with Hydrogen low carbon alternatives in the UK.

One of the biggest difficulties to overcome with the crossover to Hydrogen will be the sheer scale of installation of the new appliances within current buildings. However, there are clear advantages of using existing familiar infrastructure, reducing the need for extensive remedial works that would be seen with an electric-only alternative. Other than the boiler/water heater replacement, pipework, tanks, and heating emitters such as radiators would remain unchanged. This helps avoid major issues caused by the limitations of existing space and accessibility.

Our take…

What is clear, is that hydrogen is not going to be the holy grail of zero-carbon heating for commercial projects. The simple truth is that it would be currently impractical to switch the gas grid to 100% hydrogen for zero-carbon heat, despite the existence of the extensive natural gas grid in the UK.

Producing bulk hydrogen from renewable electricity is also still expensive, and any produced by ‘surplus’ renewable electricity is not expected to meet the scale of demand. The production of low carbon hydrogen at scale will rely on using imported natural gas and deployment of carbon capture and storage (CCS) to offer a cost-effective route to produce lower volumes of hydrogen. Even when using CCS, it is important to realise hydrogen from fossil fuels will not be zero-carbon.

But, in terms of cost-effectively reducing emissions from energy use to a very low level by 2050, producing hydrogen via a low carbon route and storing it at scale makes it a potentially valuable complement to electrification.

With the practical provision of Hydrogen still some years away for the majority of the UK, Adveco, with its’ broad experience in gas and electric water heating, plus low carbon and renewable alternatives is perfectly placed to consult on short-, mid- and long-term options for your commercial projects, whether new build or refurbishment.

Adveco Reduces the Global Warming Potential of FPi Heat Pumps by 80%

  • Switches entire FPi monobloc ASHP range to R-32 refrigerant
  • Greater efficiency from a more compact form factor
  • Perfect for hybrid DHW systems that help reduce a building’s energy consumption

Commercial hot water and heating specialist Adveco, announces the FPi32 range of more environmentally friendly air to water heat pumps designed for use with domestic hot water applications. The three models, available in 6, 9 and 12kW variants provide a low carbon source of hot water in a more compact, quieter, more efficient and easier to install unit.

With the new R-32 refrigerant circuit, this range of heat pumps address the environmental impact of previous refrigerants, whilst delivering zero impact on the ozone layer. The FPi32 requires almost a kilo less refrigerant to operate compared to the first generation FPi units, and this, with the gains from using R-32, means the FPi32 range has just 20% of the Global Warming Potential (GWP) of its predecessor.

Bill Sinclair, technical director, Adveco, says;

“The use of R32 refrigerant may be a relatively small step in terms of technical development, but its use has major implications in terms of taking us toward responsible, sustainable systems that deliver business-critical hot water without harming the environment. Not only does this go a long way towards helping businesses meet carbon targets this decade, but it also helps keep running costs low.”

Due to advanced vector control technology, and improved compressor operation by using R-32 refrigerant, the efficiency of the FPi32 is much improved over the previous generation of FPi ASHP.  With accurate response to variable operational cycles throughout the year, the FPi32 range can achieve an above-average coefficient of performance (COP) up to a very high COP of 5.23. Seasonal COP is also raised, up as high as 4.74, meaning FPi32 ASHPs can make a real difference to a property’s energy consumption.

Compatible with existing DHW distribution systems with higher thermal requirements, the FPi32 range is ideal for integration into a hybrid hot water system. Transferring heat from the air to a building, the FPi32 can provide 55°C hot water throughout the year, even when ambient air temperatures drop as low as -25°C.  When combined with either a gas or electric water heater and controls, the FPi32 helps reduce emissions and increases efficiency without compromising reliability or performance.

The Adveco FPi32 range is virtually maintenance-free, requiring simple, regular cleaning of the coil and filter. Sensors constantly check pressure, and each unit is equipped as standard with frost protection. This makes the FPi32 range of air source heat pumps an easy to install and maintain method for commercial sites to achieve lower cost, sustainable water heating.

Bridging the Gap to NetZero – Part 2

Hybrid Heating – the validity of gas in future hot water applications

In part one we looked at why you might adopt a hybrid approach to commercial hot water and heating as a route to achieving Net Zero in commercial properties. In this second part, we consider the continued validity of employing existing gas technology… 

There continues to be a call for a wide ban on the deployment of gas boilers in new properties, with a date of 2025 often mooted. Such a ban, though focussed currently only on domestic properties, would no doubt have repercussions for the commercial sector if/and when it comes to pass.  But it is worth noting that ‘hydrogen-ready’ appliances would be exempt from any broad ban, so gas has a role to play in that mix of technologies driving us forward to Net Zero.

According to Mission Innovation (MI), an independent clean-tech research programme, half of the global emissions reductions required to achieve climate targets by 2050 depends on technology that still currently remain at a demonstration or prototype phase. Whilst development continues into the provision of new fuels such as green hydrogen – and we could be looking at at least a decade before this is universally available –  there remain clear cases, especially in terms of reducing running costs,  for retaining existing gas technology for commercial applications. We also recognise that the retention of existing infrastructure is critical for the cost-effective deployment of long term next-generation green technology, especially considering the large scale challenge of retrofitting existing properties.

Since 2015 the wholesale price of electricity has climbed 20%, yet gas prices over the same period are down on average 15%.  The difference between the wholesale market price of electricity and its cost of production using natural gas provides us with the spark spread.

Commercial Air Source Heat Pumps (ASHP). At the time of writing, the spark spread is calculated to be 5.7.  For a heat pump to break even against a 90% efficient gas boiler, the heat pump must demonstrate a COP of 5.15. The Adveco FPI32-6 can exceed this COP, but only at warmer ambient temperatures. Far more realistic is to use seasonal COP, which at 5.15 is beyond the capability of most current generation units. When assessing the efficiency of commercial air source heat pump (ASHP) technology, we calculate the ratio between the electricity invested in order to run the ASHP and its output, this is the COP. The COP can be influenced by a number of factors including the energy needs and energy efficiency of a property, quality of hot water and heating system installation, and once operational, the energy manager’s competency in maximising the system output. We would expect high performing commercial heat pumps to show a COP that range from 2.9 to a very high 4.7 due to variance in seasonal external temperature and heating flow temperature. The average ASHP system will typically exhibit a maximum COP much lower than the necessary 5.15. It is also worth considering that the latest generation of commercial gas boilers will exhibit even greater efficiencies, for example, RP MD Boilers. Adveco’s MD boiler range can achieve a NET combustion efficiency of 106%. This means gas has a key role to play in ensuring a hybrid approach remains cost-effective.

As we progress forward, hydrogen-ready commercial gas appliances (boilers and water heaters) will leverage high efficiency, economic fuel blends with the additional advantage of considerably diminishing the carbon impact of commercial properties.

We see hydrogen playing a valuable role in meeting the needs for heating the UK’s commercial buildings but it will never be a 100% solution. This is why gas appliances in combination with heat pumps remain the best, and most cost-effective to deploy and operate method for commercial organisations to decarbonise operations and drive a low carbon economy.

Whether or not ongoing Government consultation decides to recognise the importance of ‘hybrids’ with financial support, the simple truth is that for the broad majority of commercial organisations looking to refurbish, capital investment and operational costs for heating and cooling systems are a critical decision factor. Hybrid systems offer the best option now and in the longer term as new green gas options come into play

The Hybrid Balancing Act

To truly reap the rewards of a hybrid heating system its energy management system needs to be implemented as part of the smart grid, with flexible electricity tariffs. When electricity volumes increase, prices fall. In a smart grid, when the corresponding price signal reaches the hybrid heating system it will be able to optimise the use of renewable electricity in terms of cost and availability.

In view of the extremely high volatility of renewable energy sources (RES) electricity, there will inevitably be peaks in supply above demand for electricity. In particular, this naturally occurs at high levels of wind and solar radiation. At present, an excess supply of RES electricity is either decommissioned at production peaks or sold. In extreme cases, as has been seen in the Netherlands, this could lead to negative electricity prices. To counteract this uneconomic development, it is necessary to introduce flexible electricity prices and pass them on to customers in order to stimulate production-dependent consumption. If there are high quantities of renewable energy in the grid, a heat pump will supply the building with heating and hot water. In cold phases, the heat pump covers only a part of the necessary heat output in the case of a hybrid system with the condensing gas boiler taking over to cover the remaining heat requirement and, if necessary, provides a higher system temperature.

This load management, the smart balancing of heat pump and condensing boiler operation, not only addresses the lifetime cost of operating a system it can help with the support of grid capacity (with fiscal remuneration if selling electricity generated), stabilisation of reserve capacities and potentially reduce the need for grid expansion.

The ability to provide greater efficiencies through smart metering and the use of flexible electricity tariffs to reduce operational costs for a lower total cost of ownership across the lifespan of the system is advantageous. The opportunity to impact load management across the grid however is a real game-changer for businesses being held up as a major guilty party when it comes to the continued generation of greenhouse gasses. Hybrid systems, therefore, offer a fast, cost-effective and realistic means to address ageing and environmentally unfriendly heating systems.

Bridging The Gap To Net Zero – Part 1

Hybrid Heating – A Practical Response For The Commercial Built Environment

Adveco looks at the changing face of commercial hot water & heating, and the increasing importance being placed on the development of hybrid applications to address the real-world challenges of achieving carbon reduction levels set by the government through to 2050.

Around 40% of UK greenhouse gas emissions are accounted for by heating, cooling, ventilation, the provision of hot water and lighting the built environment, and, according to 2019 figures issued by the Department for Business, Energy and Industrial Strategy (BEIS), business remains the third-largest emitter at 17%. In order to achieve climate-neutral building stock by 2050 commercial organisations need support from the industry to provide immediate and practical measures.

Through the expansion of wind power and photovoltaic systems, the generation of electricity from renewables and the importance of electricity in the heating market is increasing, but natural gas still dominates. As attention shifts to a mix of district heating, heat pumps, wind and solar energy, studies show that over the next two decades renewable electricity will be crucial to the energy supply in the heating market.

That said, there remain strong differences with regard to the expected share of renewable energy supply. Independent research clearly argues for a multi-dimensional approach with an energy mix consisting of renewable energy and gaseous fuels with a high share of renewable energies. Studies that are more “almost all-electric” argue in favour of almost complete dominance of the heat pump, while the technology-open scenarios also predict large proportions of heat pumps, but also assume the use of gaseous fuels.

Just as electricity is becoming greener, via an ever-increasing share of renewable energy, so too over time will the gaseous fuels such as ‘green’ hydrogen gas and synthetics.

Why Take The Hybrid Route?

So, let’s consider the advantages of the hybrid approach. This, at the most basic for heating systems, consist of two heat generators, of which at least one is operated with renewable energies and one with fossil fuel. Often, a hybrid heat pump system consists of a heat pump (air source) designed for a system part load (baseload) and a gas condensing boiler for peak load, for example during the cold, dark winter months. In a fully hybrid heat pump system, both heat generators can cover the entire heating load, where the energy sources can be freely selected according to definable criteria including efficiency, emissions and price.

Commercial Air Source Heat Pumps (ASHP).

Compared to a conventional combustion heating system though, there will be issues of logistics and space requirements, but as hybrid systems are particularly relevant to buildings in which there is already a gas connection this is generally less of a concern. That said, a hybrid system will require two heat generators and two energy connections, one of which is an environmental heat source. This leads to higher complexity of the plant, requiring more effort and expertise from the system designer, supplier and installer. This all leads to higher CAPEX cost. It is typically estimated that the purchase and installation of a hybrid heating system compared to a pure condensing heating system is going to drive initial costs up by approximately 50 to 60%. So, what are the advantages that outweigh these initial costs?

For older commercial properties where a new heating system is required, but wider renovation is either not feasible or required, a hybrid system can control and avoid issues of project congestion when refurbishing, as the heat pump is used to supplement the pre-existing fossil-based heating system.  This helps to save costs as existing boilers can continue to be operated on the currently installed heat distribution, heat transfer and flue systems while the heat pump can benefit from an advantageous coefficient of performance (COP) in the right conditions and setpoints.

A hybrid heat pump/gas boiler system is able to reduce the maximum power consumption of a system by smartly balancing the heat generators for greater efficiencies and lower operational costs whilst guaranteeing high system temperatures to ensure the comfort of those still living or working in the building during refurbishment work. If the hybrid system is also equipped with a buffer tank and domestic hot water (DHW) tank the heat pump can achieve a high proportion of cover for space heating and DHW heating increasing the profitability of the system.

A hybrid heating system cannot only be controlled cost-effectively but it can also be optimised for CO emissions by selecting the optimal (ecological) heat generator whenever possible via an energy management system that incorporates smart metering.

Hybrid systems for commercial properties will typically be planned according to individual project requirements. In cold phases, the heat pump in the hybrid system can only take over part of the heating load due to the design. If necessary, the condensing boiler, especially on cold, dark days with high demand, but a limited supply of renewable energy, completely covers the heating load.

This versatility enables the energy manager to react to price fluctuations, especially in the power grid and possibly also in the gas grid.

Should the building envelope subsequently be renovated, the required heating load decreases and the existing gas boiler can take on less of the annual heating work or eventually could be put out of operation.

In part 2 we consider the continuity of using gas for future hot water applications

A Global Roadmap to Net Zero

The International Energy Agency (IEA) has published a global roadmap with more than 400 milestones, spanning all sectors and technologies – for what needs to happen, and when, to transform the global economy from one dominated by fossil fuels into one powered predominantly by renewable energy, such as solar and wind, to realistically achieve Net Zero by 2050.

Despite the current gap between rhetoric and reality on emissions, the IEA roadmap shows that;

“…there are still pathways to reach net zero by 2050. The one on which we focus is – in our analysis – the most technically feasible, cost‐effective and socially acceptable. Even so, that pathway remains narrow and extremely challenging, requiring all stakeholders – governments, businesses, investors and citizens – to take action this year and every year after so that the goal does not slip out of reach.”

To keep the world safe, scientists say that global heating has to be limited to 1.5C by the end of this century. To keep close to that mark, emissions of warming gases need to drop by half by 2030, and essentially hit zero in 2050.

The IEA report, Net-Zero by 2050 A Roadmap for the Global Energy Sector, envisions a global economy that is twice the size of today’s, with an additional two billion people but with an 8% drop in energy demand. This pathway, the report states, requires international co‐operation and “vast amounts of investment, innovation, policy design and implementation, technology deployment, and infrastructure building.”

The plan sets to achieve this with no carbon offsets and a low reliance on technologies to remove carbon from the air. Achieving the rapid reduction in CO2 emissions over the next 30 years requires a broad range of policy approaches and technologies. The key pillars of decarbonisation of the global energy system are energy efficiency, behavioural changes, electrification, renewables, hydrogen and hydrogen‐based fuels, bioenergy and carbon capture, utilisation and storage (CCUS).

Fig 1 Solar, wind and energy efficiency deliver around half of emissions reductions to 2030, while electrification, CCUS and hydrogen ramp up thereafter.

The direct use of low‐emissions electricity in place of fossil fuels, with a complete removal of new supplies of coal, oil or gas, is one of the most important drivers of emissions reductions outlined in the report, accounting for around 20% of the total reduction achieved by 2050. Global electricity demand more than doubles between 2020 and 2050, with the largest absolute rise in electricity use in end‐use sectors taking place in industry, which registers an increase of more than 11 000 TWh between 2020 and 2050. Much of this is due to the increasing use of electricity for low‐ and medium‐temperature heat.

As part of this electrification process, and with gas or oil heating currently a major source of carbon emissions in many countries, the IEA is calling for no new fossil fuel boilers to be sold, except where they are compatible with hydrogen. This is not the first time this has been mooted in the drive towards Net Zero, one that has already been questioned by the building industry in terms of bringing enough hydrogen ready product to market, and more critically securing trained installers to fit new builds. What the report does not clarify, in the drive to emphasise efficient buildings, is how the building sector can realistically address retrofitting old existing infrastructure. For the commercial sector, this is a major issue and one that Adveco is taking the lead on, developing hybrid applications to bridge the old to the new, and developing brand new technologies that drive sustainability of larger-scale hot water and heating systems. With a strong history of developing bespoke applications and a technology-agnostic approach, Adveco is well-positioned to support commercial organisations struggling to adapt to new demands for sustainability within new and existing buildings.

To meet the need for greener energy systems where all of the world’s electricity would be emissions-free by 2040, and to expand electricity provision to the 785 million people in the world who have no access at present, requires an enormous undertaking, quadrupling the current levels of wind and solar installations. The scale of the change proposed is unprecedented, Fatih Birol, the IEA Executive Director said:

“The scale and speed of the efforts demanded by this critical and formidable goal – our best chance of tackling climate change and limiting global warming to 1.5C – make this perhaps the greatest challenge humankind has ever faced.”

The report has already faced some criticism due to the reliance on CCUS which remains an unproven technology, and bioenergy which would require a 60% increase in production. To meet this demand would require a 25% increase in plantations of energy crops and forestry to make liquid fuel or be burnt to generate electricity.

The IEA does, however, see a strong opportunity for hydrogen and hydrogen-based fuels. Demand increases almost six fold to 530 Mt in 2050, of which half is used in heavy industry (mainly steel and chemicals production) and in the transport sector; 30% is converted into other hydrogen‐based fuels, mainly ammonia for shipping and electricity generation, synthetic kerosene for aviation and synthetic methane blended into gas networks; and 17% is used in gas‐fired power plants to balance increasing electricity generation from solar PV and wind and to provide seasonal storage. Overall, hydrogen‐based fuels account for 13% of global final energy demand in 2050, with hydrogen production almost entirely based on low‐carbon technologies: water electrolysis accounts for more than 60% of global production, and natural gas in combination with CCUS for almost 40%

Hydrogen production jumps sixfold by 2050, driven by water electrolysis and natural gas with CCUS, to meet rising demand in shipping, road transport and heavy industry.

With the energy sector, according to the IEA, being responsible for around 75% of the emissions of greenhouse gases that are driving up global temperatures, limiting global heating to 1.5C by the end of this century, means emissions of warming gases need to drop by half by 2030 if they are to hit zero by 2050. The IEA warns that the greatest threat to limiting global heating is weak international co-operation, which after the mid-2030s would see the pace of emissions reductions worldwide slow markedly, delaying a global transition to net-zero by decades. This throws additional weight on those nations attending COP26, in Glasgow this November, to form major agreements on policy and co-operation.

Space To Develop Hot Water & Heating

How relocating heating and hot water systems in commercial buildings can drive real value from underutilised space…

The most valuable asset any business or organisation has is space, space to grow, develop and drive advantage. Within the built environment the drive for more space is a balancing act between granting applicable and preferably comfortable space for those using the building and meeting the infrastructural and systemic needs of operating the building.

There typically has to be some kind of give in the drive for creating or freeing up useable space if that activity impacts on the necessary systems, in particular heating, cooling, lighting and water.

Hotels are a great example of this drive to reclaim usable space. The hospitality industry is one of the most competitive there is. Hotels are continually fighting with the competition to offer the most affordable rates, the best amenities, and the most outstanding guest services — all while also making a profit. The easiest way to charge more for a room is by adding space to it, or by adding more rooms in total. Either way that is going to help improve the bottom line. The same goes for restaurants, where maximising floor space means more tables. Whilst hoteliers and restaurateurs will look to every square centimetre of their properties for opportunities to maximise revenue, other organisations will have very different drivers. Consider schools, where larger class sizes have increasingly driven a demand for teaching space. How many schools have had to surrender playing fields to locate portacabin style classrooms which are obviously not ideal?

This brings us to the kinds of underutilised or wasted ‘dead’ space in and around buildings. Internal space is potentially incredibly valuable, so leveraging external space to free it up can be truly advantageous. The question is what can be given up to makes such gains? The simple answer might be your HVAC plant.

Plant rooms, or boiler houses as they were known, vary from purpose-built to jury-rigged spaces used to accommodate heating and hot water systems. Basements are typically repurposed in older commercial buildings, whilst it is not unusual to find them tucked in amongst other rooms creating a mixed-use setting. Wouldn’t it be advantageous to separate such building services and relocate them away from those using the building whilst improving the efficiency of the system for a host of benefits including lower operational costs and reduced emissions?

Simply upgrading to a new gas condensing boiler or electric water heater can deliver notable efficiency improvements over models from just 10 years ago, and today’s modern appliances pack that into much more compact, space-saving formats. So, you could gain greater capability from a smaller footprint in your plant room, and potentially reclaim a few square meters. But what if you could reclaim the entire plant room?

Refurbishing plant to a new location may sound drastic, but that needn’t be the case. Increasingly the construction industry has embraced the idea of offsite construction, creating modular units or systems that are pre-installed and ready for relatively quick and simple connection once delivered to a site. The process streamlines a construction programme along with offering numerous savings as site work is dramatically sped up. Now, this process can be as easily applied to refurbishment projects as it is to new build. All you need is an underutilised space. For many commercial buildings that means flat roofs, yards or car parks, spaces that are inexpensive to adapt, require low to no maintenance and have either been ignored or are underused.

With the proliferation of car ownership, it might at first seem unlikely that the car park is being underused. But the drive to encourage walking, cycling and car-sharing has had an impact, and developers who have previously pushed for more open parking space than ever before are now being challenged to repurpose some of that space. In terms of Identifying functional opportunities to better leverage this space, the siting of plant fits the bill. Turing over just one or two car spaces can have a dramatic impact on the capability of heating system, providing enough square meterage to easily accommodate a mid-sized packaged plant room offering, for example, a boiler cascade and heat exchanger assembly. Or the space could be used to locate Air Source Heat Pumps (ASHP) that drive system sustainability whilst lowering CO2 emissions.

Relocation to flat rooftops is especially valuable. This is truly ‘dead space’ for most buildings, but it provides a broad opportunity to relocate heating and hot water plant safely and more securely. A simple crane lift is all it takes to locate a prefabricated plant room, and these can be of considerable size and complexity should the roof space be large enough to accommodate. Additionally, the space lends itself to locating hybrid systems that integrate renewable and sustainable technologies. We have already mentioned the use of ASHPs, and a rooftop placement not only typically supplies unimpeded airflow, the noise, though relatively low, now becomes almost unnoticeable to those on the ground.

Flat roofs are also perfect for the installation of solar thermal systems, where a framework is constructed to align the collectors for optimal energy collection. That energy is then transferred to the building’s water system. One of the biggest threats to the efficiency of a solar thermal system is the heat loss between the collector and hot water storage, which results from potentially long pipe runs from the roof to the plant room. By locating the plant room on the roof, pipe run is minimised as are thermal losses, so you get more energy for your investment.

These are just a few examples of where Adveco’s application design, system prefabrication and expertise in hybrid and renewable technology can help maximise underutilised space. Modern, high-efficiency systems deliver new versatility for addressing changing demands of the building whilst still reducing operational expenditure on energy and helping drive actual sustainability within an organisation.
