A historic mansion housing one of the world’s finest collections of antique miniatures is reaping the benefits of 21st-century green technology.
Northumberland-based re:heat has installed two wood pellet-fired biomass boilers to supply renewable heat to keep visitors, staff and the valuable collections in Nunnington Hall, near York, at the optimal temperature.
Owners the National Trust appointed re:heat, of Alnwick, after a competitive tender process to deliver the project.
The firm fitted two 50kw biomass boilers to replace an old, inefficient oil-powered heating system as part of the Trust’s environmental commitment to reduce carbon emissions at its properties substantially by switching to more renewable-energy sources and deliver 50 per cent of its energy from renewable sources by 2020.
“There were a lot of challenges to overcome with this project, but it has worked very well,” said National Trust project manager Edward Wood. “It was essential that the new system was installed quickly so that the impact on our conservation heating was minimised.
“We have to maintain our environmental conditions at the right level so our listed buildings and collections don’t deteriorate. We also need to supply comfort heating for our staff and volunteers.
“Most of this work was being done while the site was open so it had to be managed around visitors and daily deliveries. re:heat managed these challenges very well.
re:heat director Ben Tansey added: “This was a very sensitive site and the spec that we were given was quite challenging in that a very old heating system was in place which needed to be replaced to meet the Hall’s present-day and future needs.
“Cost was one of the key drivers for the National Trust, but there was also a requirement to remove potentially hazardous materials from the site such as oils.”
