Across multiple complex projects for the National Trust, Reheat has delivered over 2MW of heat decarbonisation, secured Government funding and currently manages 22 of its biomass systems.
- Reheat has played a significant role in helping the National Trust achieve its 50% renewable energy target
- Delivered over 2MW of low carbon heat projects on multiple National Trust sites
- Achieved 100% heat decarbonisation at major National Trust sites, displacing fossil fuels in the process
- 87% increase in operational efficiency of National Trust district heating schemes
It is well publicised that the National Trust has embarked on a huge climate and sustainability plan. In the last decade, it has completed more than 130 renewable energy projects across its range of historic properties and facilities, such as mansion houses, cottages and cafes. It forms part of the Trust’s strategy to generate 50% of its energy from renewable sources. Europe's largest conservation charity can now generate 24 million kilowatt hours of energy each year and has embarked on the decommissioning of oil boilers from its properties, saving 4,000 tonnes of carbon each year.
Over the last decade, Reheat has played a significant role in this decarbonisation success story, with a suite of low carbon heat solutions to remove fossil fuels and improve efficiencies across multiple projects for the National Trust in the Midlands and North of England since 2015.
Biomass system installations
The National Trust has taken steps to implement biomass heat systems across many of its properties. Sustainable biomass is a good choice for predominantly rural sites that need a direct replacement for oil-based heating systems. However, there is a complexity to designing and installing biomass systems in historic properties, including their age, listed status, the need to keep their heritage intact, and the fact they are visitor attractions that need remain open to the public.
To date, Reheat has undertaken the principal design and installation of 9 biomass systems for the National Trust totalling 2MW. including a major 440kW project at Hardwick Hall that decarbonised 100% the site's heat use. The installation have been complemented by our consultancy and service and maintenance support.
Where there were biomass boilers already installed, Reheat carried out extensive diagnostic and system renewal works to get the systems fully operational where they were otherwise falling short of expectations.
Part of this came as Reheat advised the National Trust on the UK Government’s Heat Network Efficiency scheme, delivering heat efficiency projects as a result.
Biomass system optimisation
Reheat has also performed heat system optimisation, installed heat distribution controls and has delivered some of the National Trust’s highest performing district heating schemes, including the renovation of a poorly performing biomass district heating system at Lyme Park, which now operates at 87% efficiency with a further 85% reduction in electrical consumption.
Heat Network Efficiency Scheme
Reheat also alerted the National Trust to the Heat Network Efficiency Scheme, which enable the Trust to significantly improve heat systems at two of their sites, including a biomass system at Langdale Campsite.
