West Country Estate
130 kW Woodchip District Heating Scheme
The owner decided to install a woodchip system on the estate to reduce cost and to replace a wide variety of different heating systems including oil, LPG and electricity saving on annual fuel and maintenance costs. In addition the owner was keen to make use of low value wood from the estate in order to improve woodland management.
Fuel supply and chip handling
Dunster designed and implemented the conversion of an existing and underutilised traditional farm building to cater for the chip store and boiler room. The chip store took account of the need to receive deliveries from different suppliers as well as from in house. The store was designed to take deliveries of up to 45m3 via tipping trailer minimising the need for any on-site handling of chip. Estate wood is seasoned, chipped and loaded directly into the fuel store or stored nearby and transferred by front loader.
System design and installation
The system was designed for 100% of heat and hot water to be provided by biomass. A 3,000 litre accumulator tank was installed to assist with peak heating loads and to avoid inefficient short cycling of the boiler. A back up oil boiler was installed (unused as yet!)
Estate staff installed the district heating mains to Dunster’s specifications. Dunster designed and installed all the main plant as well as local heat interfaces together with heat meters, pumps, wiring and controls.
As part of a major renovation of the mansion house requiring planning and listed building consent, the installation of the biomass system has enabled the owner to meet building regulations without the installation of double glazing.> more case studies
