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.

Meeting Regulatory Requirements – WRAS & KUKreg4 from Kiwa

At Adveco we work hard to ensure our products are fit for purpose and meet stringent UK water regulations. To ensure this, our water products are independently vetted and can demonstrate approval from both WRAS (Water Regulations Approval Scheme) and Kiwa Watertec.

The regulations set legal requirements for the design, installation, operation, and maintenance of water fittings, systems, and appliances. They have been designed to prevent drinking water contamination and prevent misuse, waste, undue consumption, and erroneous measurement. As an independent UK certification body for plumbing products and materials, WRAS approvals demonstrate that, in accordance with these water fittings regulations, a material or water fitting is of suitable quality and standard.

WRAS has been the most well-known approval among contractors, specifiers. As WRAS approval certificates no longer involve the water authorities themselves in the decision making, the water authorities refer to a product requiring compliance with Regulation 4. Not specific to WRAS, Regulation4, states that:

“every water fitting should be of an appropriate quality or standard and be suitable for the situation in which it is used.”

Regulation 4(2) provides options to demonstrate compliance, such as CE Marking where applicable, appropriate British or European standards, and also a specification approved by the regulator. This approval is demonstrated with the KUKreg4 approval mark, issued by Kiwa and has become an accepted way of demonstrating compliance for several years for water authorities, specifiers and contractors, who gain assurance that the product in question has undertaken the required testing, and meets the necessary design requirements for its use. Similarly, approval granted by WRAS means the product is of suitable quality and standards to avoid water contamination and minimise waste when installed properly.

Anything from pipes, fittings, taps, showers, washing machines, dishwashers, to coffee machines, boilers and toilets, all need to comply with the Water Supply (Water Fittings) Regulations and bye-laws. If a product in your property is found to be non-compliant with these regulations, a replacement can be demanded, with all the associated unplanned costs. Should unregulated fittings be deemed dangerous then prosecution is also possible. The regulations impose a legal duty on everyone to use suitable water fittings when connected to public water supplies. So, ensuring products meet regulations with the correct approvals in place is important.

Whilst approval is not mandatory, the testing of the products is. It is worth remembering that not all products sold have been appropriately tested although most buyers understandably assume that anything sold to them will meet legal requirements. So looking for the appropriate WRAS or Kiwa approved statement or logo is time well spent. Water authorities are regularly using the terminology that products must be ‘Regulation 4 compliant’, contractors and installers still need greater visibility of KUKreg4 in the industry. But they should recognise its validity and be able to communicate that with clients who may be unfamiliar with the certification. Regulation 4 compliant testing is undertaken in an ISO 17025-accredited laboratory and complies with ISO 17065 product certification.

For reference, KUKreg4 is not only accepted across Europe, but it also offers two levels of compliance – level 3 and level 1+. Level 3 is the equivalent service offering of WRAS (initial testing, no annual audits and a full re-test after five years). Level 1+ involves initial testing, but no full re-test after five years is required – assuming there are no significant changes to the product – as certification is maintained via annual audits of the manufacturing facility.

It is also worth noting that WRAS approval may restrict how a product may be installed and used. To help installers, every water fitting approved is listed with one or more “requirement and installation notes.” These explain any installation conditions, which must be followed, which were applied as a condition of each WRAS Approval.

All water installations in the UK need to comply with the Water Supply (Water Fitting) Regulations. This is important for public health, for safeguarding water supplies and promoting the efficient use of water within premises across the UK.

Tackling Global Warming – Why COP26 Matters

Boris Johnson took to the stage last week to announce we must “grow up” as a species at the UN General Assembly. The UK Prime Minister spoke on how we must look towards greener living for the Glasgow Conference of the Parties (COP) 26 summit. This congregation, it is hoped, will build upon the Paris accord that, in 2015, for the first time saw a singular agreement for tackling global warming and cutting greenhouse-gas emissions.

Why is COP26 So Important?

COP26 will see representation from 200 countries to present plans to cut emissions by 2030 to keep global warming “well below” the Paris established 2°C above pre-industrial levels. The ultimate goal for tackling global warming is to aim for 1.5°C with Net Zero emissions by 2050 to avoid greater climate catastrophe by the end of the century.

Johnson observed that this is our “turning point” to do better and “that means we need to pledge collectively to achieve carbon neutrality – net zero – by the middle of the century.” He expressed clearly the urgency in the actions needed to be taken to, not only, save ourselves but the many species which live on this Earth.

Those countries attending are expected to formally announce their plans for reducing emissions and tackling global warming in the coming weeks prior to the commencement of the summit, with more announcements expected during the two weeks of planned talks.

The US has announced a major investment in green initiatives with an $11.4bn per annum contribution in climate finance and China this week has announced plans to cease construction of overseas coal plants. Though generally welcomed, the latter move currently fails to address the use of domestic coal-fired plants, one of the easiest ways for green gains to be quickly achieved at a national level.

The Real Challenge of “Going Green”

With coal removed, the challenge of tackling global warming really sets in. The UK’s carbon budgets are well known to now be off track, and the Green Alliance has stated current plans will deliver less than a quarter of the cuts needed to meet the UK’s aggressive 2030 climate goal – intended to cut 78% of emissions from a 1990 baseline by 2035. The target also fails to account for emissions created abroad in the process of manufacturing goods bought in the UK. This issue of embedded carbon in the supply chain is a complex and difficult challenge that will no doubt be brought to bear on commercial organisations already facing ESOS audits and SECR reporting, and is why open, large scale support for COP26 from the likes of China is so critical.

Here in the UK, the government’s promise to put effective policies in place has been slow to materialise. Disagreement over the future of gas boilers and wider green funding has held up key announcements that should be delineating much-needed guidance for a commercial sector facing immense change and considerable capital and operational outlay if Net Zero is to be realised.

An End to Coal Power?

There is, however, a cautious sense of progress, with great attention being turned to the meeting in Rome late in October of the G20 nations.  Together these are responsible for 80% of current global emissions. If these nations can agree to cease the use of coal, COP26 has the potential to be one of the most decisive events since Paris if it can lead to a speeding up of the global phasing out of coal power. Then the real work starts. Additional agreements on the reduction of deforestation, a more rapid switch to electric vehicles (EVs) and wider protection from the impact of climatic extremes are all expected to be key objectives.

Johnson declared how these opportunities to become greener are not out of reach as “We have the technology: we have the choice before us.”

Striking a Balance When Heating Commercial Buildings

From the commercial perspective, Adveco is one of the leading proponents of how technology can be best applied when tackling global warming by supporting a more sustainable approach, particularly for the delivery of business-critical hot water. We recognise the importance of excluding fossil fuels from future commercial systems and advocate all-electric systems for new builds. We also understand the implicit costs and difficulties of retrofit and replacement of systems throughout the thousands of legacy commercial buildings that define the UK’s urban landscape. For this reason, we also strongly support the continued use of gas, but within a hybrid approach to provide cost-effective, lower carbon applications that remain future-ready for next-generation Net Zero technologies, and in particular Hydrogen mixes for commercial hot water & heating.

Finding the Answer to Schools Sustainability

The Government’s drive toward Net Zero and its “green industrial revolution”, last November gave a clear message that publicly funded organisations would be expected to be leading the charge when it came to demonstrating sustainable developments. The Department for Education (DfE) has already increased focus on property-related efficiency, and the expectation is this will only increase if schools sustainability is to be delivered across their estates.

But understanding how a school property’s assets contribute to overall performance, and how individual assets perform against technical criteria for sustainability has never been more challenging for estate managers.

The complex technical issues that surround commercial-grade domestic hot water (DHW) and heating applications within schools demand strategic, real-world understanding. Not only are there physical limitations when it comes to technologies on offer, but there are also considerable variances in capital expense and ongoing operational costs that without doubt contribute considerably to the annual costs of running a school. That is a critical issue for authorities and academies that need to balance the demands of change within often restrictive budgets.

The challenge of meeting schools sustainability goals

For education sites that typically exhibit a large DHW load, there remains a strong argument for employing gas-fired water heating. And, just as electricity is becoming greener, so too can the gaseous fuels when blended with hydrogen and other synthetic fuels. With publicly funded organisations increasingly being mandated to demonstrate clear and real investment in sustainable and low carbon technology schools face a complex, real-world and political challenge.

Far too often, school hot water systems suffer from poor application design where a lack of understanding of different types of hot water system leaves systems oversized to prevent perceived hot water problems. Inefficient and less environmentally friendly, such systems are more costly to build and operate for their entire lifespan. This can be further exacerbated by the complexities of introducing Air Source Heat Pumps (ASHP) – the current clear preference of the Government – and Solar Thermal systems.

With ASHPs offering greater efficiencies in low-temperature systems, the high-temperature demands of domestic hot water (DHW) for school applications can be a challenge. It is recommended to calculate emissions at a working water temperature from the ASHP of 55°C, this is then hot enough to provide realistic levels of preheat for a commercial DHW system. Schools’ applications using heat pumps are going to be complex and, when compared to gas-fired alternatives, are going to have higher up-front and operational costs. Offsetting these additional investments though are new efficiencies and sustainability that reduce CO₂ emissions.

Now is also a good time to reconsider the integration of a solar thermal system as part of the premises. Not only a proven and extremely reliable technology, for the past 15 years solar thermal has offered a clear path to reducing CO₂ emissions for sites that rely on large amounts of hot water.

Solar Thermal provides an effective way to offset the new financial burden that comes from moving from gas to currently far more expensive electricity. A ten-year return on investment becomes very achievable, and, with zero emissions, the undisputed carbon and cost savings make this technology increasingly more viable.

Solar has always been used as a preheat with the coldest water possible to maximise the efficiency and output: this gives maximum free heat with no carbon emissions. But there is also a good case now for using solar thermal with heat pumps and electric if set up as a mid-heating system which can lower both carbon and cost.

A Simple Choice

For the time being, schools looking to decarbonise their systems have a simple choice, use either solar thermal or ASHP to preheat water, and gas or direct electric as after heating. By using preheat you can offset up to 75% of a systems energy demands and thereby actively reduce carbon emissions. All these technologies can be made to work together, but for new builds, the expectation will be to fit a heat pump and direct electric system. For pre-existing systems that use gas then the additional use of solar thermal is recommended. This also has the advantage of retaining gas-based system infrastructure, so the building has the option, at a later date, to evolve its use to green gas alternatives. So if you already use gas on-site do not feel pressured into removing it quite yet.

None of the above is a single, all-encompassing answer for schools seeking to achieve Net Zero, but when used together they can provide reliable, business-critical hot water and heating systems that deliver value for capital investment, exhibit lower ownership costs over their lifetime and will help to meet current sustainability targets. They also provide a clear path for the integration of new technologies, such as high-temperature heat pumps and hydrogen ready appliances which will ultimately help to deliver Net Zero by 2050.

At Adveco, our dedicated application design team provide accurate, bespoke sizing, for both new build and refurbishment projects. Once correctly sized, we can recommend, supply, commission, and service the optimal appliances whether they be gas, electric or a mixed hybrid approach that incorporates solar thermal, heat pumps and heat recovery systems. This is the best way of ensuring schools hot water demands are met in the most cost-effective and sustainable manner.

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 FPi32 also features low noise impact with quiet 52dB operation.

The FPi32-9’s compact monobloc form factor also makes it perfect for integration into Adveco’s Packaged e-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.

Bill Sinclair, technical director, Adveco, said, “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.”

The winners will be announced at the National ACR & Heat Pump Awards on October 20th and we wish all the other 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.
