National Trust puts its trust in LPG powered CHP

Cornwall’s Trelissick Garden has become the first National Trust property in the UK to install a CHP unit run on LPG. Rurally located near Feock, close to the city of Truro, Trelissick Garden used to rely mainly on Calor LPG to provide fuel for the onsite catering facilities. But when the restaurant and café were to be extended and refurbished, it was the ideal time to integrate a low-carbon heating solution into the mix.

Trelissick Garden estate manager Chris Curtis said: “At the National Trust we are always looking for ways to minimise our environmental impact and we try to include greener options whenever possible. We considered various options to meet the greater heat and electrical demands of the refurbished restaurant, but the LPG fuelled CHP unit seemed ideal.”

A DACHS CHP unit was installed to act as a lead boiler with the additional benefit of providing onsite electrical generation. The CHP heat output is supported, as required, by standby LPG fired condensing boilers controlled by the building management system. Chris Curtis concludes: “The system is extremely energy efficient and we are looking forward to economical as well as environmental benefits.”
