Commercial hot water and heating trends 2021.

2021 – Adapting to new technologies and approaches

/in , , , , , /by

The UK’s construction industry is familiar with adapting to new technologies and approaches to provide the latest and most efficient responses for creating better buildings.  2020, however, was unprecedented, but what does this mean for 2021? Looking forward, key trends within the industry include Covid-19 care, greener response sand efficient use of property space.

Coronavirus has attacked every corner of the UK, impacting the majority of businesses and therefore the wider economy. Despite vaccines, Covid-19 is now something we all must learn to live with, it has accelerated change and requires a re-evaluation of how buildings are conceived and used. As a specialist in the provision of commercial heating and especially hot water, Adveco is well versed in the design of systems to support the maintenance of hygiene within their buildings, critical for the ongoing prevention of the spread of Covid-19. There has never been a greater need for access to wash stations. Scientists have proven washing hand in warm, soapy waters for more than 20 seconds can reduce the spread of Coronavirus more efficiently than hand sanitisers. Additionally, hot water (at a minimum of 60°C) needs to be readily available for cleansing of materials and surfaces to prevent the spread further. With these requirements comes a need for more efficient systems capable of meeting these increased demands to be incorporated into commercial buildings. With the demands of maintaining a safe two-metre distance, space has become even more valuable. The hospitality sector is already struggling with the challenge of balancing revenue losses from reduced covers and are looking at how to create alfresco spaces to adapt to this new normal. Packaged plant rooms offer companies a means to use minimal space whilst still maximising efficient systems, freeing up valuable internal spaces or making use of dead spaces which are not customer friendly. This is also a fast, relatively low impact method for refurbishing hot water systems.

Despite all the chaos of Covid-19, it also brought into razor-sharp focus the effects of pollution. This was all too obvious when the world stopped for a moment and the effects of pollution decreased and allowed the environment to thrive. It proved to be a rallying cry for decarbonisation in 2020 and will continue to create headlines throughout 2021 and beyond. It remains a core focus for the construction and HVAC industry that will continue to strongly push for more wide-reaching frameworks to deliver eco-friendly technology and buildings to meet the challenging goal of achieving Net Zero by 2050.

Through exclusive technical partnerships and our in-house design function, Adveco can quickly adapt to these changing needs and help innovate products and systems to directly address the evolving challenges of decarbonising commercial buildings. We recognise that there is no single technology that delivers the entire answer, but there is no doubt Air Source Heat Pumps (ASHP) will play an important part, as will new green gas technologies towards the end of the decade.  This makes hybrid system approaches all the more valid for supporting the near-term transition of commercial organisations to a more sustainable track that reduces their building emissions and operational costs.

UK Needs to Cut Emissions by 78% by 2035 to Meet Net-zero

/in , , , , /by

Under the original Climate Change Act, the UK pledged to cut net emissions by 80% by 2050. Now, it will need to deliver a 78% reduction by 2035 if it is to meet its long-term net-zero commitment. That is according to the Climate Change Committee (CCC), which has published its Sixth Carbon Budget for the period between 2033 and 2037.

The CCC described the budget as the toughest yet with chief executive Chris Stark saying that the UK will need to decarbonise at a faster pace in the next 30 years if the net-zero target is to be met. Stark explained that the Committee has deliberately opted to ‘front-load’ decarbonisation – more will need to happen in the 2020s and the earlier half of the Sixth Carbon Budget period than in the latter half and the 2040s. Heat, and the broader decarbonisation of buildings, is one of the major priorities identified by the CCC which has based its calculations on a scenario in which 40% of the emissions reductions needed will be delivered using pure-technology solutions.

The new recommendations will see heat supply drastically transformed from its current reliance on natural gas if the country is to decarbonise all aspects of the UK’s infrastructure and economy. The budget has set a mandate for fossil fuel boiler installations to end across the UK entirely from 2033, with fossil fuels phased-out from heating in public buildings by 2025 and in commercial buildings by the following year. It added that these stricter targets to phase out higher-carbon technologies in public buildings would also support a government aim of realising a 50% reduction in emissions by 2032. The 2033 date has been set to take account of the typical 15-year turnover of boiler stock, while also allowing for the scaling-up of supply chains to deploy heat pumps at a mass scale.

The recommendations aim for 37 per cent of public and commercial heat demand to be met by lower-carbon sources as of 2030.  According to the CCC, heat pumps should cater for 65% of the predicted need, 32% of heat should be provided by district heating systems, whether low or high-temperature supply, with a further 3% from biomass by the end of the current decade. By 2050, CCC estimates that 52% of heat demand should be met by heat pumps, 42% from district heat, with hydrogen boilers covering the remaining 5% of national demand.

One caveat, however, was that since the dates operate alongside the deployment of low-carbon heat networks and planned regional rollouts of hydrogen conversion of the gas grid, the phase-out outlined may not apply in any areas designated for these alternatives. This makes a nod to a net-zero that derives balance between pure hydrogen systems and electrification, both delivering decarbonisation of heating. It also highlights the danger of supporting one technology and ignoring another when the pace of development is so much steeper and will continue to be so as we move towards 2050. To this end, the CCC is using what it describes as a ‘balanced pathway’ scenario upon which to base its calculations and that its delivery will require ‘systems change’ and a ‘whole economy approach’ to decisively meet the UK’s legal target of fully eliminating and offsetting carbon emissions by 2050.  Under this ‘decisive’ decarbonisation plan, the CCC has warned that a sizable majority of change must be made within 15 years.

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.

Adveco L70 Air Source Heat Pump (ASHP).

Adveco L70 ASHP For Hot Water With 70% Less CO₂

/in , , , , , /by
  • 90 kW maximum output for hybrid domestic hot water and heating
  • Specifically designed for the UK climate (-20°C to +35°C)
  • Reduce CO₂ by as much as 70% compared to gas-fired systems

Nov 9th 2020 – Commercial hot water and heating specialist Adveco extends its range of commercial air source heat pumps (ASHP) with the introduction of the Adveco L70. This high-capacity air-to-water monobloc heat pump is designed for the UK climate providing hybrid domestic hot water (DHW) and heating.

Bill Sinclair, technical director, Adveco said:

“In conjunction with Adveco’s bespoke application design, the L70 offers a comprehensive response for sustainable heating and hot water, providing high-efficiency, low-emission, low cost to operate systems for the life of a commercial building.”

Rated 70kW for typical UK operation at 5°C but climbing to a maximum 90 kW from a single compact unit, and with a seasonal coefficient of performance (SCOP) as high as 4.08 the L70 is perfect for large scale commercial applications and can operate as part of a cascade installation for projects demanding greater capacity. The L70’s dual compressor configuration allows for staged start-up to limit current draw and gives the flexibility to drop to half output under low load conditions.

With ASHPs offering greater efficiencies in low-temperature systems, the high-temperature demands of commercial DHW applications can be a challenge. Achieving working flow temperatures up to 60°C, the L70 supplies preheat for hybrid applications composed of combinations of plate heat exchangers, buffer vessel, with calorifiers, gas-fired boilers or direct-electric water heating providing essential additional heat to meet commercial requirements.

The L70 will dramatically lower CO₂ when analysed using the carbon intensity figures from the new SAP10.  Compared to gas-based systems the carbon emissions are reduced by around 70%, when using the SCOP of 3.47 measured at 55°C flow temperature (Ecodesign warm European temperature zone with a reference design temperature of 2°C).

The L70 remains eligible for applications for the non-domestic Renewable Heat Incentive (RHI) until March 2022 and is ideal for projects applying to the Government’s Public Sector Decarbonisation Fund to drive energy efficiency.

Funding Retrofit For Public Buildings.

Funding Retrofit for Public Buildings

/in , , /by

The Government’s Public Sector Decarbonisation Fund is a £1billion fund being made available now for the upgrade of public buildings and social housing to make them more energy-efficient and environmentally friendly. Projects with a focus on decarbonisation of heating and hot water will undoubtedly be a priority when granting funds as, according to 2019 figures issued by the Department for Business, Energy and Industrial Strategy (BEIS), heating, cooling, ventilating, and providing hot water and lighting for the built environment still generates 17% of greenhouse gas in the UK.

Part of a wider £3b plan to upgrade the UK’s buildings, the plan has been generally welcomed, as it is hoped to support up to 120,000 jobs across the construction sector, as well as boosting local investment through local job creation.

Designed to aid public sector organisations in England, including central government departments, agencies, local authorities, and especially schools and NHS Trusts. The plan’s intention is to improve buildings’ operational performance, reduce CO2 emissions, raise comfort levels for staff, plus reduce in building-related complaints and maintenance backlogs. This is to be achieved through the specification and installation of energy-efficient and low carbon heating measures.

However, the fund is only being made available for a single year, and since its announcement in July, has raised queries over whether government departments and local authorities have the time or resource to spend this effectively. Facility and energy managers responsible for public sector real estate should already be exploring their options for project design and delivery, not least because of the wider concerns over project timescales in the wake of Covid-19. It is, therefore, crucial to be scoping out retrofit projects as soon as possible.

At Adveco, we have almost 50 years’ experience supporting the refurbishment of public sector heating and hot water systems. While studies show that over the next two decades renewable energy sources (RES) – a mix of district heating, heat pumps, wind and solar energy – will be crucial to the energy supply in the heating market, we would lean towards more technology-open scenarios that not only predict large proportions of heat pumps but also assume the use of gaseous fuels. Just as electricity is becoming greener so too can the gaseous fuels which will contain larger shares of renewable ‘green’ hydrogen gas and other synthetic fuels by 2050. This supports the adoption of a hybrid approach that combines new and existing technologies, which we not only see as more practical but is both cost-effective and less influenced by the volatility of a RES electricity-only approach. The hybrid approach is especially valid when it comes to refurbishing old and inefficient systems, as well as extending viable systems where fresh demands outpace the original scope of the application.

From the latest high-efficiency, ultra-low emission condensing gas and water heaters to electric appliances, sustainable solar thermal and air source heat pumps, Adveco is deliberately positioned can support the introduction and integration of the latest technology. Typically, the latest generation of appliance not only is more efficient, but it can also offer a far more compact footprint, so makes refurbishment simpler, and without needing extensive building work to accommodate plant require less capital expenditure. If systems require scaling up to meet increased demands for heating and domestic hot water (DHW) then refurbishment can quickly become more complex, and if a hybrid system is employed, greater space may be required for the dual systems, as well as additional controls and pipework. Should the availability of space be an issue Adveco can design and build off-site prefabricated plant rooms that make full advantage of unused space, such as flat roofs, to expand capabilities.

If a hybrid heating system is chosen, it offers great advantages for cost-effective control, for example, 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. And, by selecting the optimal (ecological) heat generator whenever possible (via an energy management system) it can also be optimised for CO2 emissions. Should the building envelope be renovated, the required heating load decreases and the existing gas boiler can take on less of the annual heating work, and it could eventually be put out of operation.

An extra £50m will fund social housing through a demonstrator project for the Social Housing Decarbonisation Fund (SHDF). This UK-wide demonstrator scheme will see grants supplied to upgrade the energy efficiency of over 2,000 of the worst-performing social homes. Again, Adveco has a long heritage designing and delivering multi-occupancy applications for heating and DHW.

To secure climate-neutral building stock by 2050, public sector facility managers desperately need help to achieve practical and cost-effective sustainability. At Adveco we can help with a full-service application design team who can provide an assessment of your properties’ demands and correctly size an application. We can help recommend the optimum appliances to deliver highly efficient systems that provide the best value in terms of capital and operational expenditure, whilst meeting the need to reduce emissions. Our commissioning service also ensures installation is carried out correctly and the system is safe to operate, which then unlocks long-term manufacturer quality warranty service.

The Hybrid Approach

In part one, we considered the challenges and limitations of an Air Source Heat Pump (ASHP) only system, with particular focus on the problems commercial organisations faced when retrofitting existing properties with new heating and hot water applications. In this concluding part, we look at the advantages of adopting a hybrid system approach based on ASHP technology…

A hybrid approach where an ASHP is deployed in a packaged combination with a gas boiler and control system presents an attractive alternative, retaining the element of gas boiler technology that customers are comfortable with. Plus, it also offers better compatibility with existing heating distribution systems and thermal demands of higher heat loss buildings meaning less adaptation is required. There are also technical advantages, such as the ability to optimise heat pump efficiency and switching to the gas boiler at times of network peak.

The facility of two heat sources to meet the demands for space heating and/or hot water is especially relevant for the commercial sector where bespoke system design is often required to meet the particular needs of a project, such as applications with a high heat loss. In this case, the gas boiler can be operated to meet peak demands on the coldest days, allowing the heat pump to be reduced in size compared to the capacity of a pure electric heat pump system.

Installing a heat pump alongside an existing gas boiler, together with a control system also makes sense in retrofit installations, especially, in applications where a relatively new boiler has been installed, which should be highly efficient, and which can be retained for peak heating loads. The key challenge technically is to ensure that the control system for the ASHP and existing boiler operate together efficiently.

In such cases, given that the ASHP does not replace an existing heating system, the driver for installing the system is largely to reduce running costs and make quick gains towards improving environmental performance.

Hybrid systems based around an ASHP are likely to require some system refurbishment in many retrofit installations in order to ensure that a substantial proportion of the annual demand is met by the heat pump (though this is likely to be lower than a pure electric system). Even so, when including the cost of a gas boiler replacement, the cost of refurbishing heating systems for the installation of a hybrid system should be lower than in the case of a single heat pump system. This is due to the reduced heat pump capacity requirement since the boiler can provide higher flow temperatures to meet peak heat demands. When comparing the cost of a heating system refurbishment opting to install a hybrid system versus a ‘pure’ ASHP system a reduction in comparative costs of as much as 50% could be achieved (Source: Frontier Economics).

Once installed, levels of carbon savings are generally slightly higher when allowing for hybrid solutions – suggesting that up until 2030 hybrid solutions could be consistent with meeting carbon targets. Although the average cost-effectiveness of carbon abatement is somewhat lower than in the scenarios which exclude hybrids. These savings are estimated based on comparison with a standalone ASHP, assuming that a hybrid system will use a smaller heat pump with a capacity reduced by as much as one third. For a hybrid ASHP system, expectations will be for the heat pump to meet as much as 75% of the annual heat load, the remainder being met by a gas boiler. This delivers similar operating costs and comparable CO and CO₂ savings at current grid carbon intensity (the reduced heat pump coverage of the overall thermal demand can be compensated by the ability to run the heat pump at closer to optimum efficiency).

Whilst the long-term use of hybrid systems may be perceived as not fully consistent with meeting carbon targets and they can equally be limited by space requirements and noise issues that also affect standalone ASHP installation, there remains a strong argument for their use across the commercial sector.

In the long term, hybrid systems should fall behind pure electric systems in terms of carbon benefits as the grid decarbonises and may become less cost-effective if volumes of gas supplied for the heating drop. But looking out to 2050, innovations in the provision of hydrogen and green gas, using extant infrastructure which currently supports 85% of UK heating, means hybrid systems may prove to be a defining low carbon option. One that provides the means to support the very particular, practical needs of the commercial market with versatile, cost-effective systems, all without sacrificing the drive to lower emissions as part of the process of achieving net-zero.

Understanding the Challenge of Air Source Heat Pumps (ASHP)

Commercial organisations face a somewhat unfair challenge as they are held by the Government to be leaders in the move to control and reduce carbon to achieve net-zero by 2050, yet are limited by the technology options that the Government is showing active support for. The current drive, without a doubt is to push Air Source Heat Pumps (ASHP) to the exclusion of other technologies. Neither high-efficiency gas boilers with ultra-low emissions nor proven sustainable systems such as solar thermal have received much love in the latest round of grants supporting the commercial sector. In particular, the decision not to provide support for those opting for hybrid solutions that bridge the technology gap in the most cost-effective manner shows a focus on the finish line, but a failure to grasp the actual challenges the commercial sector faces right now. So, what are the options with ASHPs, and what is a realistic path to take today?

Unfortunately, we cannot control the weather, but despite that, ASHP technology does still present an opportunity to significantly improve the efficiency of buildings across the commercial sector. Because an Air Source Heat Pump is reliant on the ambient air, the Coefficient of Performance, or COP, is going to be affected by both the source and supply temperatures. The heat provided is at a much lower temperature, so a heating system will be required to operate at low temperature for optimum efficiency and may have to be kept on for a longer period to be fully effective. Such a system could well require a significant upgrade to a building’s electrical supply and heating infrastructure. However, to maximise the ASHP efficiency, the lowest possible flow temperature needs to be achieved, and that requires a building to be highly efficient in terms of heat loss. When working with new builds, the ability to drive high efficiency in the thermal performance of the fabric of a structure means a well-designed commercial heat pump system is more than capable of providing all the heating needs for a business and, in the long term, represent good value for money in savings from reduced energy bills, as well as helping commercial premises bring down that all-important carbon footprint.

But in isolation, this demand for low heating temperatures and low water usage will be impractical for many businesses, especially when retrofitting a property, which can highlight the limitations of ‘pure’ ASHP systems. This becomes particularly obvious when ASHP is to be deployed for the provision of hot water, especially if there is a large daily demand. Domestically we would expect a minimum storage temperature of 50oC, but this rises to 60oC minimum for commercial environments. This has a considerable impact on the ASHP’s running efficiency and therefore the running costs. Additionally, by generating hot water at 50oC and not 70oC, the storage volume will have to be considerably larger than that associated with a typical gas boiler. To achieve necessary water temperatures requires greater considerations of space planning and type of hot water cylinder the system will require.

With early to market performance of heat pumps falling below expectations, and a higher capital cost relative to the conventional gas boiler alternative the uptake of ASHP in commercial business on the gas grid had, until the drive to achieve net-zero, been limited. Now commercial operations are actively seeking to use commercial ASHP, but are still running up against these same issues, which is why, with the current capabilities of ASHP technology, a hybrid approach for commercial applications remains attractive. Both in terms of installation and operation, whilst still gaining the all-important running cost savings and reduced carbon emissions.

In part 2 we explore how a hybrid approach can deliver significant value from commercial ASHP technology

Adveco’s Packaged E-Hot Water System makes particular use of the FPi-9 ASHP to provide the system preheat from 10°C to 50°C, supplying 70% of the DHW load.

Offsetting 70% of the energy requirement means the Packaged e-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.

A completely new specification that lowers the heat intensity, without detrimental effect to the demands for hot water, means the Packaged e-Hot Water System is also more resistant to scale, reducing maintenance demands.

The GLE also has an additional 6kW immersion heater to provide backup in case of failure of the lead heat source for sites where hot water is business critical. The Adveco designed control system monitors the heat sources, and in the case of failure, it can automatically activate the backup system.

Adveco’s Packaged e-Hot Water System is ideal for a wide range of commercial properties with regular hot water demands such as restaurants and boutique hotels, offices, schools, and light industry. The system is also perfect for both new builds or refurbishment where space is at a premium.
