Forward For 2022

As we look forward for 2022, Greg Brushett, Adveco’s UK Sales Manager, highlights recent product innovation and how as a business we are focussing efforts on supporting customers to navigate toward a more sustainable future for their buildings…

Adveco Ltd is an industry-leading company, which was established in October 1971.  Renowned as specialists in commercial hot water, heating and low carbon applications, the company develops, manufactures and supplies technologies, applications and systems.

“We work with consultants, specifiers and designers, providing informed support and partnership through our application engineering team to design and deliver systems optimised to be highly efficient and cost-effective. For contractors, we offer a single, versatile, specialist sales resource that ensures delivery of the most cost-effective system. Facility and energy managers are supported through product remote monitoring, technical support, warranty and maintenance service to ensure system longevity and help realise low total cost of ownership.” Stated Greg Brushett, UK Sales Manager.

Anchoring Adveco’s sustainability push forward for 2022 is a full range of commercial gas and electric water heaters, boilers, and solar thermal systems, versatile buffers, thermal storage, heat recovery and Air Source Heat Pumps (ASHP).

R32 commercial Air Source Heat Pump (ASHP). 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 use of R32 refrigerant has major implications in terms of taking us toward responsible, sustainable systems that deliver business-critical hot water without harming the environment,” explained Greg.

Packaged plant room and ASHP. Designed and built offsite and delivered ready for rapid installation when space is at a premium, the Adveco Packaged e32-Hot Water System provides a pre-sized, resilient, environmentally friendly, low carbon hot water system that utilises the FPi32-9 ASHP to help offset up to 70% of the energy requirements. This compact weatherproof GRP structure provides a complete all-electric hot water plant room which demonstrates 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.

Placing the utmost importance on customer satisfaction, the company not only supplies its range of off the shelf products, Adveco specialises in providing a bespoke solution for its customers. Providing a tailored, individually designed solution ensures that each application/system is correctly sized to make optimal product recommendations, and then supplied with manufacturer grade after-sales support.

“We choose or design products to be as highly efficient as possible, reducing operational costs and cutting or completely removing harmful CO and Noₓ emissions. Both are a critical requirement for organisations, CO especially as they strive to introduce greater sustainability on the route to achieving net-zero.” Mentioned Greg.

In terms of recent developments, Adveco released its new range of stainless-steel high-pressure indirect water heaters and storage tanks for applications in UK soft water areas; the Adveco ATSI, ATST, ATSH, ATSR and ATSB ranges. These vessels are available up to 1000L and are all rated to 10 bar as standard.

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 FPH-S range provides a single, easy to accommodate, highly effective response for organisations with small to medium basin and sink-led hot water demands” says Greg. “With Fusion, customers gain optimum efficiencies to lower the carbon emissions from a building project.”

As the company looks forward for 2022 it continues to celebrate its 50th anniversary, Adveco maintains a fiercely independent approach which is enabling the company to further extend its portfolio of select, high-quality products to better address the changing needs of a nation set on a path to Net Zero by 2050. Greg added, “Unifying the business under the singular Adveco brand we are better positioned to bring together a greater choice of quality product, all backed by real-world experience and engineering excellence.”

New Building Regulations to come into force in June 2022

Under new building regulations, CO2 emissions from new commercial buildings, including offices and shops, must be reduced by 27% under new rules announced by the government to help the country move towards net zero.

In a government statement, which identified that heating and powering buildings accounts for 40% of the UK’s total energy use, the installation of low carbon technology, such as solar panels and heat pumps, was identified as a core opportunity to help cut emissions – “lowering the cost of energy bills and helping deliver the UK’s climate change ambitions.”

All new residential buildings, including care homes, student accommodation and children’s homes, must also be designed to reduce overheating, making sure they are fit for the future and protect the most vulnerable people.

These new Building Regulations, which set the standards in England for the design, construction and alteration of buildings, follow a public consultation and will come into effect from June 2022.

The intent is that the new building regulations will raise standards and will “pave the way for the Future Homes and Buildings Standard in 2025,” which will address making sure new builds are net zero ready, avoiding the need for retrofit.

There will be a six month period before the new regulations come into force on 15 June 2022. Transitional arrangements are in place which means that if a building notice, initial notice, or full plans for building work are submitted to a local authority before 15 June 2022, then provided the building work commences by 15 June 2023, work on that individual building is permitted to continue under the previous standards.

Balancing Commercial Gas Heating & Sustainability

When it comes to specifying commercial gas heating,  COP26 has heightened awareness for the need to reduce fossil fuel consumption, and with most of the national infrastructure currently ‘on gas’ and delivering half of the UK’s non-transport primary energy needs, building owners and operators will be looking at their options.

For older properties that account for a high proportion of the existing commercial building stock, a transition to all-electric applications, or implementing effective use of heat pumps, can represent a costly, technical challenge. As such, many will be looking to hydrogen alternatives. But with a government decision on the technology not due until 2026, its’ usage, if supported nationally, will take time to become commonplace. As such natural gas-fired boilers will, for the time being, remain a preferred option for the provision of commercial space heating, so how can this help drive sustainability into the built environment?

Increasingly stringent legislation aimed at reducing carbon emissions and hazardous air pollutants is already driving the specification of systems that are based on high efficiency condensing boilers, or a hybrid approach that combines these boilers with heat pumps to provide low carbon, effective heating.

The cost-saving functionality of high-efficiency condensing gas boilers can be readily demonstrated, but what of the air quality and sustainability of the technology?

Commercial Gas Heating – Sustainability & Air Quality

Adveco’s MD boiler range, for instance, has been designed so that the highest efficiency is at the low end of the firing range, condensing boilers typically operate at 94-95% combustion efficiency. MD’s high-efficiency pre-mix burner can achieve ideal combustion efficiency of up to 107% (net)/98% (gross) reducing energy costs and producing low emissions. With low CO (19 ppm) and NOX (34 mg/Nm³) emissions, a heating system built around a high-efficiency MD condensing boiler (Class 6 appliance) easily satisfies the requirements of the Energy-related Products (ErP) directive when specifying commercial gas heating in a building.

Adveco’s MD boiler range, for instance, can be used to create a cascade of up to eight 280 kW units, each combining four 70kW heat engines pre-stacked in a single, elegant casing. This approach can provide more than 2200kW while occupying minimal plant room floor space. Correctly sized and professionally commissioned, such boiler cascade systems with high-efficiency pre-mix burner can provide a high 1:20 modulation ratio. This, along with built-in cascade control ensures that efficiencies are maximised no matter the heating load of the building. With the input of the boiler easily altered to closely match the heating load, the system is better able to derive as much heat out of the exhaust gases as possible. This efficient reuse of heat also results in low flue gas temperatures allowing for the use of standard 80-160mm diameter plastic flue pipe (PP). PP is efficient, environmentally friendly, and significantly cheaper than stainless steel, offering a cost-effective and space-saving alternative in terms of pipe run.

For commercial projects that face the most stringent legislation and oversight, high-efficiency condensing boilers remain a realistic and effective means of meeting the demands for improved building sustainability. Especially if used as part of a hybrid system where continuous low-grade heat from the heat pump works alongside the fast responsiveness of the gas boiler to top up the heating at electricity peak demand times, thus avoiding the requirement for higher carbon-emitting generators. Crucially, and despite recent price fluctuations, gas continues to offer considerable economic advantages in terms of operational costs for built assets. We currently would still therefore advocate a modular cascade concept. This takes full advantage of the compact size afforded by condensing natural gas boiler technology, such as the MD, with its low-water content heat engines, and built-in redundancy. The latest generation of condensing gas boilers represent a familiar, reliable response to a building’s heating demands that dramatically improve on the efficiency of older boiler technology to deliver immediate emission reductions. Critically this approach retains the infrastructure necessary for the introduction in the next decade of green gas variants with all the promises of much lower carbon emissions that will carry the commercial sector towards the national net zero goal by 2050.

COP26 – The Impact On Commercial Buildings

COP26 is now well underway with cautious optimism over initial agreements on reducing coal, global methane levels and rates of deforestation. But what does the event mean currently for those focussed on buildings in the commercial sector here in the UK?

Firstly, more than 40 nations representing over 70% of the world’s economy and every region have stated they will commit to ‘turbo-charging’ the uptake of clean technologies by imposing worldwide standards and policies at COP26. The five sectors that the plan will cover at first are steel, road transport, agriculture, hydrogen, and electricity, with the intent of encouraging global private investment in low-carbon technologies. The aim is to draw in trillions of dollars in private finance for cutting emissions, and businesses seeking to export into the EU must reach the same standards, so we can expect this to strongly impact the UK.

The Treasury has also outlined at COP26 new sustainability disclosure requirements (SDR) for large UK businesses. Under these new Treasury rules, financial institutions and companies with shares listed on the London Stock Exchange must come up with net-zero transition plans, which will be published from 2023. These net zero transition plans and sustainability claims must be ‘clearly’ justified to set a science-based ‘gold standard’. The government will set up a Transition Plan Taskforce of industry leaders, academics, regulators and civil society groups. The strategies will need to include targets to reduce greenhouse gas emissions, and steps that firms intend to take to get there. However, the government has admitted there is “not yet a commonly agreed standard for what a good quality transition plan looks like”, and the UK was not “making firm-level net zero commitments mandatory”.

450 firms managing banks, insurers and pension funds controlling 40% of global financial assets – equivalent to £95tn – have though aligned themselves to limit global warming to 1.5C above pre-industrial levels. Such private investment in green technologies over brown investments is vital in the march towards net zero by 2050. An example of this was the announced “Breakthrough Energy Catalyst” programme at COP26, which aims to raise up to $30bn of investments and bring down costs for ‘green’ hydrogen, direct air capture of CO² and long-duration energy storage.

But there still remain unanswered questions over what government support for the commercial sector is going to look like, and when it will materialise?  Non-mandatory regulation changes and dependence on private finance to green economic trajectory in the hope that businesses will decarbonise of their own accord remains questionable, especially outside the realms of big business.

At the start of 2021, there were 5.5 million small businesses that account for 99.9% of the business population (5.6 million businesses) in the UK according to the National Federation of Self Employed & Small Businesses. These companies’ buildings continue to generate a considerable proportion of UK emissions, so further support for them is critical. In the coming week, delegations will try to further raise awareness of the need for greater support if building emissions are to be successfully addressed.

Efforts to achieve large scale decarbonisation of buildings have focussed on new builds and recognising a building’s full lifecycle in terms of its carbon cost. But consider this, 97% of EU buildings are in need of renovation, so tackling existing properties must be addressed, only then can a more holistic carbon plan be put in place to support commercial properties to be more energy-efficient and able to support low carbon hot water and heating. This would not only address issues of embodied and emissive carbon but could help reduce air pollution and contaminants that, according to the World Health Organisation (WHO), contribute to the deaths of 120,000 Europeans a year. This issue is raised in an open letter to those attending COP26 from trade bodies that include the European Heat Pump Association amongst others, calling for action on appropriate air quality, thermal comfort, control and automation systems within buildings.

Heat and Buildings Strategy Unveiled

The Government’s commitment to decarbonising the UK’s electricity system was confirmed by Prime Minister Boris Johnson and Business and Energy Secretary Kwasi Kwarteng last night with the announcement of the Heat and Buildings Strategy, a “plan to move to clean energy and a carbon-neutral economy.”

The key points announced intend to drive down the cost of low carbon heating technologies like heat pumps, and invest in working with industry to ensure that in future they are no more expensive to buy and run than fossil fuel boilers. Of the £3.9 billion of new funding to decarbonise heat and buildings, £450 million would be funnelled into a domestic Boiler Upgrade Scheme launching in April to help fund the installation of heat pumps for domestic heating.

£1.4 Billion For Public Sector Heating

The remaining funds will be invested over the coming three years through the Social Housing Decarbonisation Fund, the Home Upgrade Grant scheme, and the Heat Networks Transformation Programme and for reducing carbon emissions from public buildings through the Public Sector Decarbonisation Scheme which will be allocated £1.425 billion.

The plan accepts that there will need to be a mix of new, low-carbon heating responses for different property types in different parts of the country – such as electric heat pumps, heat networks and potentially hydrogen. With funding intended to ensure all new heating systems installed in UK homes from 2035 to be low carbon. As previously observed, though, the replacement of a gas boiler with a ‘Hydrogen ready’ appliance would not be in breach of this ‘no new gas boilers’ after 2035 stance. Additionally, gas generation continues to play a critical role in keeping the UK electricity system secure and stable, the development of clean energy technologies intends that it be used less frequently in the future.

The statement from Prime Minister Boris Johnson concludes, “The Heat and Buildings Strategy sets out how we are taking ‘no-regrets’ action now, particularly on heat pumps, whilst supporting ongoing trials and other research and innovation on our future heating systems, including on hydrogen. We will make a decision on the potential role for hydrogen in heating buildings by 2026, by learning from our Hydrogen Village pilot. Heat pump technology will play a key role in all scenarios, so for those who want to install them now, we are supporting them to do so.”

A Luke Warm Reaction?

This much-delayed Heat and Buildings Strategy announcement should be a rallying call to kick-start Britain’s new heat pump industry, and the Government’s continued policy to address carbon emissions is to be applauded. However, the scale of investment appears to fall far short of the numbers typically cited to start to really move the needle when it comes to reducing national carbon emission levels. It also ignores the potential complexity and additional costs surrounding the installation of heat pumps into existing buildings. There also remains considerable question marks over how funding will apply to the commercial sector and for other low carbon systems such as solar thermal. Low cost, low carbon heating for homes is a strong political message, but this sector still only accounts for 15% of the UK’s harmful emissions (Source: BEIS 2019 UK greenhouse gas emissions). Business still accounts for 17% of emissions, with transport and energy supply generating 48%.

The launch of the Heat Network Efficiency Scheme (HNES) demonstrator programme aims to increase the provision of heating services provided to businesses, but as the Government states, “There will be no single policy or technology that cuts carbon emissions to virtually zero, but a diverse mix of technology, such as heat pumps and potentially heating appliances fuelled by hydrogen, alongside green projects like heat networks, that will combine to decarbonise heat in buildings over the next three decades.”

Greater clarity from the Government regarding its position on support for improving hot water and heating systems within non-public sector commercial buildings, therefore, remains elusive. For small to medium enterprises in particular this remains a considerable barrier to introducing low carbon alternatives prior to 2030.

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.

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.

Green Heat Network Fund Set to Open to Applicants in 2022

The Government has released initial details of its Green Heat Network Fund (GHNF) which will open to applicants in England from April 2022 and is anticipated to run until 2025, incentivising new and existing heat networks to move away from high-carbon sources.

With decarbonising heat set as a key part of the Government’s heat and buildings strategy, the new fund is intended to replace the existing Heat Networks Investment Project (HNIP) that has been available since 2018.

The £270 million GHNF will only support low-carbon technologies such as heat pumps, solar and heat recovery in the rollout of the next generation of heat networks. The intent is to help cut carbon emissions from domestic and commercial building heating – which accounts for 21% of the UK total – making it one of the country’s largest carbon emissions sources.

Heat networks, supplying heat to buildings from a central source, are intended to provide large-scale renewable and recovered heat. The GHNF will only support applications if they include low-carbon heat-generating technologies, such as heat pumps and waste heat with the aim of incentivising and kick-starting the demand for heat pumps as part of a wider mix of low-carbon heating options.

Although heat networks currently meet approximately 2% of the overall UK demand for heating, the independent Committee on Climate Change (CCC) has estimated that, with continued support, they could provide 18% by 2050.

The Green Heat Network Fund is expected to fund the delivery of an estimated 10.3Mt of total carbon savings by 2050.

What you Need to Know About Net Zero Now

What is “Net Zero”?

With greenhouse gases predicted to reach record highs by 2023 and no sign of slowing, the warnings of the impact of global warming and climate crisis are increasingly becoming apparent to all.  As UN nations converge to address the fundamental issues of climate change, it has become a “front and centre” issue for UK businesses.

In 2008 the UK Government introduced the Climate Change Act legislating for change to reduce the UK’s greenhouse gas emissions by 80% by 2050 and then in 2019, increased the commitment to a 100% reduction which has come to be known as “Net Zero”.

“Net Zero” means that any emissions are balanced by absorbing an equivalent amount from the atmosphere. The Government’s current aggressive response is to drive positive movement across every sector to meet these goals, with a focus on domestic, commercial, transport, agriculture, and industrial usage across the UK.

The effects of Greenhouse gases

As we draw closer to 2023, the effects of global warming are undeniably present, with prior predictions becoming reality — loss of sea ice, accelerated sea level rise, and extremes of weather with heavier rainfall and flooding, plus longer, more intense heat waves leading to drought and wildfires.

The world was amazed by the effects of COVID-19 lockdowns on the environment as the global pause rapidly led to positive improvements, surprising even scientists at how we can truly meet our 0% emissions goals and begin to save our planet by 2050.

How can we meet these goals?

The possibilities of making these goals achievable are very high, and we can all make the smaller changes necessary to do so. However, change for the commercial sector comes with added complexity but also greater rewards. Heating and hot water have long been recognised as key contributors to emissions from across the built environment. They of course are also rightly regarded as business-critical services.  Decreasing the use of fossil fuels to meet the “Net Zero” goal seems obvious, and “simply” changing to a more sustainable energy system can considerably reduce emissions. But there are other key business considerations to take into consideration, with everything from running costs to the capital investment required to modernise both building fabric and systems high on the agenda. Building regulations also play a major role in decision making, and there remains considerable confusion over what “green” technologies should be adopted and when…

Our name is derived from “Advantage Eco”, so it is fair to assume we firmly believe in the need for decarbonisation and the drive to attain Net Zero across the commercial environment before the 2050 deadline. That said, we are also 50-year adherents of the value of deploying gas in commercial hot water applications. This is because of the necessary high temperatures required for safe operation and the cost-effective operation it offers businesses. Like the rest of the UK’s gas-based service market, we have high hopes for the eventual introduction of green hydrogen-based alternatives to fossil gas, with potentially a much lower impact on existing infrastructure and simpler, more cost-effective like for like appliance replacement.

But we also recognize the limitations of a hydrogen-centric viewpoint, not least in terms of achieving national distribution on the scale currently expected by gas users. So, there must be real-world alternatives in play now if achieving Net Zero is going to become a commercial reality. From the proven capabilities of solar thermal systems supporting either gas or direct electric to low carbon air to waterside heat pumps and direct electric heating, there are clear paths of evolution open to organisations seeking to move onto the path to Net Zero. Our experience as a specialist creator of commercial hot water systems can help you as an organisation redefine the way your buildings consume energy and reduce your generation of harmful emissions without impacting critical offerings that define daily operation and the comfort and safety of staff and customers alike.
