Commission: The castle was previously being heated using oil at great expense. Douch Biomass was commissioned to supply and install a large 995kW biomass boiler. The boiler heats two 20,000 litre buffer tanks to meet their heating and hot water requirements of the whole estate at much lower cost.
Boiler Type: Herz 995kW Biofire with two 20,000 litre buffer tanks
Fuel Type: Wood Chip
Fuel Storage: Purpose built, three-sided storage building with a smaller low-walled pit containing an auger system that delivers wood chip to the boiler. Chip from the main storage area is moved to the pit by a vehicle when needed.
CO2 emission reduction: 6218 tonnes over 20 years
Case History: One of the larger systems that Douch Biomass has installed is the wood chip, biomass system fitted at Hever Castle. The installation provides heat not just to the castle but also to the Tudor Village, also known as the Astor wing, as well as many other dwellings on the estate. All of the wood used to fire the boiler is grown on or close to the estate, ensuring Hever Castle has the lowest possible carbon footprint.
Date Completed: October 2013
