The Path to Low Carbon Hot Water

When it comes to tracing a path to low carbon hot water, the design of applications for commercial hot water systems has remained remarkably consistent and if a building is more than ten years old it is going to be built around either a condensing gas water heater or an indirect water heater and boiler. Gas-based hot water systems were specified because this was the most cost-effective and cleanest way of producing high-temperature hot water.

In the past decade though we have seen a seismic shift in thinking driven by the wide acceptance of the harmful effects of global warming and a need to address its root causes. This solidified with the introduction of the Climate Change Act in 2008, and the subsequent drive to make the UK net zero by 2050. With the resultant closure of coal-fired power stations and increasing dependence on wind and solar, the carbon intensity of grid electricity has reduced in line with gas, which has, in turn, remained relatively static since the 1990s.

With the Government’s aggressive new Net Zero Strategy, despite similar carbon intensities for heating from either gas or electric, the latest regulations as outlined in the Heat & Buildings Strategy will deem gas systems alone to be too carbon polluting in commercial-scale buildings. So what path to low carbon hot water can you take? To decarbonise domestic hot water (DHW) applications there are currently two core technology options, air source heat pumps (ASHP) or solar thermal. Although both can provide low or zero-carbon heat, neither can fully replace an existing water heating system. Since commercial DHW systems must operate in excess of 60°C to prevent the threat of legionella, ASHP efficiency, designed to work with lower temperatures, rapidly falls away limiting supply. Solar thermal on the other hand is limited by the sun’s availability across the year, and it is worth remembering will not provide space heating either. However, both can be used as a source of preheat to reduce energy use. Both will work equally well with after heat provided by either gas or direct electricity.

Choosing the right path to low carbon hot water for your building

For buildings already on gas and that rely on large amounts of DHW – a large proportion of current commercial UK properties – solar preheat is the preferable option. Depending on the site and energy consumption habits, solar thermal will typically provide around 30% of the hot water demand.

For new build properties, the expectation is for specification to default to a mixture of heat pumps and direct electric afterheat. For new commercial builds, consultants are specifying for greater electrical load to account for the additional power demands. This though is a costly addition for legacy properties wanting to introduce electrification for higher demands of hot water and heating.

The electrification of buildings is the most common vision, and one the Government is driving with its aggressive target to achieve 600,000 new heat pump installations every year by 2028. Many of these will be for domestic properties, but a considerable proportion will be expected to be introduced via commercial projects. New DHW systems will predominantly follow this model, taking advantage of heat pump performance efficiencies to create a hybrid approach to deliver pre-heating for as much as 75% of the water in a direct electric system. And with no gas to the building, no local generation of NOₓ and no flue to install this clearly has its advantages. This is certainly why the government is championing this technology as the preferred path to low carbon hot water and heating.

However, this approach does not factor in running costs.  While the grid may have reduced its carbon, its cost per kWh has risen consistently over the past two decades. Gas prices on the other hand have remained essentially static until the latter quarter of 2021.  Of course, a proportion of the grid electricity is still generated by gas-fired power stations, so electricity charges also spike in response to any upward fluctuation in gas price. Despite the ASHP performance efficiencies, this has meant the running costs still increase approximately three times due to the difference in current gas/electric prices. For smaller hot water demands in new builds, where the need for a gas supply has been avoided, that additional cost may be acceptable. And we certainly see larger organisations faced with ESOS audits and SECR reporting be willing to absorb the increased running costs to introduce sustainability into their properties as a part of their corporate net zero policy.

Commercial sites with existing gas should really look at continuing to use it. Ten years ago, it was very difficult to argue for introducing solar thermal because the numbers really did not stack up against the price of gas. The capital costs of installation and maintenance versus the operational savings meant many early projects failed to recoup their investment, even with the support of RHI.

Today we are in a very different situation, and if electrical costs can be offset, then the numbers really start to look favourable for adopting solar thermal. A ten-year return on investment becomes very achievable and the property gains undisputed carbon and cost savings. Additionally, the current generation of condensing gas water heaters incorporate features such as flow regulation to automatically optimise the supplied output from the heat exchangers ensuring maximum efficiency. Models with multiple integrated heat exchangers offer load balancing for optimal long-life operation and inbuilt redundancy guaranteeing continuity of service. Those offering titanium-stabilised stainless-steel construction are also highly resilient; meaning warranties on the heat exchanger and burner components can be as much as a decade and operational lifespan should easily be 15+ years. That places replacement well into the early to mid-2030s and that is important because it means gas infrastructure remains in place for adaption to the next generation of hydrogen-based gas supply. The Government expects this will be a core component for meeting net zero at a national level, especially for buildings with higher energy demands. With hydrogen policy to be confirmed in 2026, retaining gas in existing commercial buildings keeps options open and future-proofs a building for other emerging heating technologies.

While we must all recognise the importance of excluding fossil fuels from future commercial systems and advocate all-electric systems for new builds, it is important to 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. The hybrid approach is unavoidable for commercial projects seeking a path to low carbon hot water and is the most sensible, practical, and cost-effective option. Whether all-electric or using gas after heat, commercial organisations can actively drive sustainability and retain control of operational expenditure for decades to come.

FUSION Commercial Hybrid Hot Water Systems from Adveco

  • FUSION is a complete range of low carbon hybrid heat pump and electric hot water systems
  • Resilient stainless steel water heating suitable for all UK regions
  • Compact design for new build and refurbishment projects seeking greater sustainability

Commercial hot water specialist Adveco, introduces the FUSION FPH-S range of low carbon, all-electric, packaged hybrid hot water systems. FUSION harnesses Adveco’s FPi32 Air Source Heat Pumps (ASHP), a high-pressure ATSH calorifier with electric immersion, controls, and metering to provide a reliable, high-temperature, sustainable and cost-effective system for new commercial build and refurbishment projects.

FUSION is available in 16 pre-specified variants with 6 or 10 kW preheat and 9 or 12 kW electric top-up, with capacities ranging from 200 to 500 litres all rated at 10 BAR for high-pressure applications. Able to meet a range of continuous capacity hot water demands from 257-377 litres/hour makes FUSION highly adaptable for a wide range of commercial buildings.

The FPi32 ASHP is specified to supply a working flow of 50°C for system preheat throughout the year, even when ambient air temperatures drop as low as -25°C. Electric immersion top-up then raises system temperatures in the calorifier to the necessary 60°C to meet commercial requirements for safe hot water demands. The stainless steel construction of the ATSH also makes it an excellent all-rounder, resistant to soft water corrosion and, with FUSION’s unique low electric immersion heat intensity (6W/cm²), is more resistant to scale build-up in hard water areas.

The physical design, dedicated controls and integrated metering ensure the ASHP preheat, and immersion work seamlessly to deliver the highest operational efficiencies. This enables FUSION to make the greatest gains possible from the heat pump, even when ambient temperature and system demands fluctuate. These gains offset much of the direct electrical energy usually required, delivering 53% carbon emissions saving and helping control the operational costs of providing business-critical hot water.

“For organisations with small to medium basin and sink led hot water demands and a desire to embrace a more sustainable business model, the FUSION FPH-S range provides a single, easy to accommodate, highly effective response,” says Bill Sinclair, technical director, Adveco. “By choosing one of these packaged hybrid water systems you gain optimum efficiencies, lower your carbon emissions and can be assured building regulations are being met for your commercial project.”

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.

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.
