Government Publishes Strategy to Decarbonise Heating in the UK

Government Publishes Strategy to Decarbonise Heating in the UK

In a positive week for climate action, the Government has published its Net-Zero Strategy and Heat in Buildings Strategy, the former detailing how the nation will decarbonise in a way that will “transform every sector of the global economy”. Like buses, you wait for one to come along and then they all come at once! There is certainly a lot to digest.

Looking to the Heat in Buildings Strategy, we are hopeful that this provides a good roadmap to decarbonise heating in the UK. Key takeaways from the strategy include:

  • All new heating systems installed in UK homes are to be low carbon by 2035
  • Plans to reduce the costs of heat pumps by at least 25-50% by 2025 and towards parity with boilers by 2030
  • £5000 grants to incentivise households to install low-carbon heating solutions

Matt Lowe, Essco Commercial Director comments,

“We welcome the publication of the Heat in Buildings Strategy and are pleased to see that heat networks are set to play a meaningful role in the government’s plans as a proven scalable option for decarbonising heat. Whilst the grant scheme is a positive step, we hold judgment to see if this incentive can go far enough to have a significant impact on the replacement of fossil fuel boilers”.  

He continues, “Time’s not on our side, and It’s more important than ever that we develop sustainable technology that works with nature to heat and cool our buildings more efficiently. Essco continues on this mission, whilst supporting our customers as we move to a low carbon future”.

£4 Million BEIS Funding Scheme for Underperforming Heat Networks

Is your Heat Network underperforming? Take advantage of the new Heat Network Efficiency Scheme (HNES) Demonstrator fund.

This £4.175 million grant scheme was recently launched by BEIS to improve the performance of existing district and communal networks. Funding goes towards work that will increase system efficiencies and lower running costs.

Find out more about the application process by visiting the GOV website here.

Significant Energy Savings for Heat Battery Installation

Significant Energy Savings for Heat Battery Installation

We recently supplied a Sunamp heat battery to replace a gravity fed system with a vented cylinder.  The heat battery is served by a Solar Diverter (EDDI Panel) as its primary source of energy, fed by a 4kW Solar PV array. The heat battery can also be charged using the Worcester Greenstar 8000 life 30kW system boiler (natural gas) as a backup.

This system feeds five bathrooms (four showers, one bath), one kitchen and one utility room and is more than capable of meeting the demands of this family of four + one dog.


  • Sunamp UniQ HW 12 +iPV Heat Battery – delivering up to 25l/min of DHW at 55°C (The equivalent of a 284 litre DHW cylinder)
  • 4kW Solar PV array
  • Worcester Greenstar 8000 life 30kW system boiler (natural gas)


Throughout the year, peaking in the summer, the heat battery offers huge savings on gas usage by utilising solar PV charging and this coupled with exceptionally low heat losses make for an ultra efficient solution.

For this installation, In the first 6 months of operation gas consumption has been reduced by around 70%, which equates to a saving of around £40 per month for the homeowner. A more detailed report of the energy use, running costs and carbon savings will be provided once the system has been in operation for a full 12 months.

Sunamp Heat BatteriesBENEFITS

  • Reduces running costs and cuts carbon emissions by using electricity from Solar PV
  • Instant hot water at mains pressure
  • Failsafe: backup internal electric heating element
  • Extremely low heat losses
  • No mandatory annual maintenance check
  • Significantly reduced legionella risk
  • Quick to fit, meaning lower installation costs
  • Space-saving: up to 4 times smaller than the equivalent hot water cylinder
  • Modular: easily combined to increase storage capacity
  • Reduced Legionella risk due to minimal stored water

One man’s waste is another man’s treasure!

One man’s waste is another man’s treasure!

Predicted savings of £14k* for the first year of this new heat recovery system.

Our knowledge and experience in heat transfer, fluid mechanics, process engineering and hydronics were put to good use recently at an asphalt production facility in Avonmouth. Here we provided a bespoke heat recovery system for John Wainwright & Co. Ltd.

This industrial heat recovery project benefited from the Department for Business Energy and Industrial Strategy’s (BEIS) IHRS programme, with the funding application supported by Essco as part of a package of services.

The heat recovery system is operational and has a forecasted reduction in CO2 emissions of around 145 tonnes per annum. This translates to an anticipated fuel saving of up to 4%, which is around £14,000 per annum*.

Kevin Saunders, Business Improvement Manager at John Wainwright & Co. Ltd comments

“This project represented a significant investment and is the epitome of our commitment to the environment. Under the guidance of Simon Lumkin (Project Lead) and continued support from Lawrence Rogers, a great team worked extremely hard to deliver an energy efficient system we believe is the first for our industry. The system was carefully designed by Lawrence ensuring it delivered energy savings without compromising the production process.”

Technical Details

The system design at the Wainwright’s facility operates by recovering waste thermal energy through the aggregate drying process and re-injecting this recovered energy into the process to reduce the burnt fossil fuel consumption on site. Air to water heat exchanger technology is used to capture the otherwise wasted thermal energy in the exhaust flue and transfer this to a hydronic system. This recovered thermal energy is used to pre-heat the combustion air onto the 19MW gas burner resulting in a reduction in fuel usage onsite. Additional waste thermal energy is also recovered from a nearby air compressor and this is injected into the combustion air pre-heating process to further boost the efficiency of the system and reduce fossil fuel consumption.

Lawrence Rogers, Essco’s Principal Design Engineer reflects

This was a fantastic project to be involved with, designing a bespoke package offering with attractive energy savings alongside low parasitic loads and with minimal risk to current production. The project was not without its challenges (COVID aside), such as the harsh environment the equipment must operate in, however, these challenges were overcome and a robust, low maintenance system was delivered.”

Industrial Heat Recovery Support (IHRS) programme

The Government’s Industrial Heat Recovery Support (IHRS) programme made an important contribution to enabling this project at a time when decarbonising industry and optimising energy use is vital. The grant funding received was crucial, as without it the project did not meet the Company internal rate of return. Research undertaken for the Feasibility Study identified two key areas for heat recovery that would help to decarbonise the process and support Environment, Social and Governance benefits.

Essco works closely with the Government’s Industrial Heat Recovery Support (IHRS) programme (now Industrial Energy Transformation Fund IETF) and can advise where this may be a suitable option and take care of the application process from start to completion.
