The National Trust has installed its first high-temperature ground source heat pump system. Comprising 6,000m of underground pipes, 32 vertical boreholes and four high-temperature heat pumps, the system has been installed at Kingston Lacy in Dorset.
Replacing the stately home’s existing boiler will save an estimated 30,000 litres of oil and 57 tonnes of carbon a year. The trust hopes the new heat pump will improve conservation of the mansion’s art collection by stabilising temperatures and humidity levels.
