Adveco AD named Finalist in the H&V News Awards 2022

Commercial hot water specialist Adveco announces that the AD water heater range has been selected as a finalist in the commercial heating category of the H&V  News Awards 2022.

Securing its nomination through innovation, effectiveness and environmental impact, the Adveco AD offers a range of commercial semi-instantaneous gas condensing water heaters composed of four models, from 70 to 280 kW supplying up to 5088 l/h of DHW recovery Δt 50°C.

“We are honoured to once again be selected as a finalist in the H&V News Awards 2022,” said Greg Brushett, UK sales manager, Adveco. “The AD with its patented powerful, space-saving design has been our response to the increase in the daily demands for year-round hot water within the commercial sector.”

Conceived for high-demand semi-instantaneous hot water applications, to utilise the AD to its full potential, Adveco recommends combining the AD with a 200 – 2500 litres capacity buffer storage tank (such as Adveco’s SSB-D). Such a system, with optimised DHW direct heating, will guarantee consistent DHW with stable temperature even when making small withdrawals, as well as providing higher availability of DHW during peak period withdrawals.

AD’s exceptional operational responsiveness and highly effective performance can also be deployed in order to supply peak demands and redundancy for commercial buildings with an existing gas connection and large-scale ASHP to water systems.

“Equally applicable to both new projects or renovation work where a lack of space would traditionally stall or quickly drive up costs of a project.  The AD provides a tough all-around choice, even in corrosive soft water areas where other commercial water heaters will struggle,” adds Greg. “And with ultra-low emissions as a result of highly efficient combustion, these capabilities make the AD stand out in the marketplace and worthy of its finalist status.”

The winners will be announced at the Heating & Ventilation News Awards on Thursday 24th November 2022. Good luck to all the finalists.

Adveco’s FUSION FPH-S hybrid hot water system provides a range of low carbon, all-electric ASHP-based packaged hybrid hot water applications. The complexity and typical requirements of bespoke hybrid systems for commercial applications can make the integration of heat pumps in DHW systems more expensive and complex to install compared to traditional gas-fired alternatives. FUSION removes this complexity with its pre-sized options which harness Adveco’s FPi32 Air Source Heat Pumps with a compact, high-pressure ATSH calorifier with electric immersion. With dedicated controls and metering, FUSION provides a complete, low-carbon hot water system for a wide range of commercial end uses.

The Adveco FPi32 provides the system with a compact monobloc-designed air-to-water heat pump providing preheated hot water at a working temperature of 50°C. 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. For a project that has to drive sustainability within the building but also meet pressure requirements greater than six bar, then the FUSION is by far the most efficient and cost-effective choice.

The Adveco AD offers a range of compact commercial semi-instantaneous gas condensing water heaters composed of four models, from 70 to 280 kW. Conceived for high-demand semi-instantaneous hot water applications, Adveco AD’s patented space-saving design makes it equally applicable to both new projects or renovation work where a lack of space would traditionally stall or quickly drive up costs of a project. The perfect all-rounder, especially in soft and softened commercial hot water applications, exceptional operational responsiveness and highly effective performance means AD can also be deployed in order to supply peak demands and redundancy for commercial buildings with an existing gas connection and large-scale ASHP to water systems.

The HVR Awards will be announced on September 29th 2022.

Public Sector Funding for Decarbonisation

Public Sector Funding for Decarbonisation

The government has launched its latest phase of public sector funding for decarbonisation, dedicating up to £635m for building upgrades to improve energy efficiency and install a range of clean technologies through schools, hospitals, and other public buildings.

Forming part of a wider £2.5bn programme, Phase 3 of the Public Sector Decarbonisation Scheme is providing £1.425 billion of grant funding over the financial years 2022-2023 to 2024-2025. The funding aims to support the government’s goal of reducing emissions from public sector buildings by 75 per cent by 2037, compared to 2017 levels, as set out in the Net Zero and Heat and Buildings strategies.

As the government looks to tackle soaring energy costs, it is intended that the funding will support a wider reduction in energy bills, to the tune of up to £650m a year over the next 15 years. As we have outlined, reducing emissions and energy costs do not necessarily go hand in hand, especially if working with heat pumps to supply hot water.

According to The Department for Business, Energy, and Industrial Strategy (BEIS) 734 grants had been awarded to public sector organisations across England to date, with phase one of the scheme supporting up to 30,000 jobs in the clean heating and energy efficiency sectors.

Applications for public sector funding for decarbonisation open from September and the government has issued guidance on how public bodies can apply for the latest wave of funding to be delivered on behalf of the government by Salix Finance, which also provides financing packages to help public sector bodies undertake energy-saving projects.

Salix Finance chief executive, Annie Shepperd, has urged public sector organisations across the country to move quickly to curb their energy use ahead of the significant increases in energy costs that are widely expected this winter.

“There is no time like the present to push forward with the decarbonisation agenda as our country must meet its ambitious targets to reduce our carbon footprint and reduce our consumption of very costly energy,” she said. “This vital work is driving down our carbon footprint and making these buildings better places for people to work in and for the public to use.”

Business and Energy Minister Lord Callanan said, “By helping even more public sector bodies ditch costly fossil fuels, we are taking an important step towards a more sustainable future while driving economic growth across the country and continuing to support tens of thousands of jobs.”  He also claimed that the scheme was already delivering upgrades to “hundreds of public buildings across England, making them cheaper to run and saving taxpayers millions of pounds each year”.

While such claims relating to public sector funding for decarbonisation should be appropriate to new build structures, upgrading existing buildings is a far more complex activity than these statements suggest. The focus on decarbonisation to address climate change is the only clear guaranteed deliverable at this time with the technology being promoted, which is predominantly heat pumps. Further work needs to be done by the government to push other technology opportunities, such as solar systems and especially solar thermal for water heating which has become an increasingly cost-effective and proven approach and hydrogen blend in the grid if cost savings are to be factored into the argument for embracing green initiatives at a commercial grade.

Heat Pumps – The Cost Of Reducing Emissions

With the government strongly advocating the use of heat pumps as a method of delivering net zero targets for commercial properties, we have noticed the trend for broad statements implying that while cutting emissions, heat pumps also reduce the energy costs for a building. It’s just not that simple argues Adveco’s UK sales manager Greg Brushett. So what is the cost of reducing emissions?

We strongly support the advantages of heat pumps as part of an all-electric or hybrid domestic hot water (DHW) system to achieve carbon savings. With DHW equating to as much as 20% of the total energy demand for domestic buildings and anywhere from 10-70% for commercial properties, it is important to clarify how heat pumps are being employed in a building’s system.

With a gas-fired system, you can achieve a safe DHW storage temperature without a significant impact on the overall efficiency but with a heat pump you need to either force the compressor to work very hard, which will reduce the Coefficient of Performance (COP) or, in a lot of cases, use the heat pump to partially heat the hot water and then use an immersion heater  – which has a COP of just 1.0 and therefore higher energy costs – to do the remaining work. If you are willing to accept this extra cost, working flow temperatures of 50- 55°C from the heat pump to an electric or hybrid DHW system are more than achievable year-round in the UK, and emissions will be dramatically reduced.

However, broad statements such as “heat pumps reduce costs” or “gas boilers remain more economic to run than heat pumps” are inherently misleading.

A heat pump can supply a properly insulated building’s heating system completely, and if designed well enough, can achieve a COP of 3.0, or slightly more, giving a similar yearly cost (within 10%) to that of a gas-fired heating system This would also be more attainable with the recent change in gas and electricity prices.

The same is not true of a hot water system. Following initial modelling and analysing reports from live systems a hot water hybrid system that achieves 50°C with an overall COP of 2.76 and uses an immersion heater to top up to 60°C has an overall efficiency of 2.4 based on the weighted average. Using these results, the running costs of the system are seen to be significantly higher than a gas system. However, the argument does demonstrate that incorporating heat pumps into an electric-only DHW system shows considerable savings over a COP of 1.0. Partnering this with other technologies such as solar thermal will only increase the benefits.

Benefits or efficiency?

Making the right choice between heat pump or gas depends on what an organisation is intending – whether seeking active emission reduction now, or, if already on gas, securing cost-saving operation until sustainable technology further matures, and costs fall.

Heat pumps can give incredible carbon emission savings for existing buildings, but as a way to reduce energy costs, replacing a gas-fired boiler/water heater with a heat pump doesn’t always add up. Commercial properties have unique demands, especially for DHW, making better application design and installation all the more important when it comes to specifying the right technology. Be wary of claims being made regarding the application of heat pumps, especially for the provision of DHW when it comes to calculating the cost of reducing emissions.
