“The Guntamatic Powerchip 100 has lived up to all expectations. Quite simply it does everything it says on the box”Darren Lucking, Higher Combe
Higher Combe, a large residential estate on Dartmoor, comprises a main residence, two cottages, office complex and swimming pool with a pool house. They wanted to reduce running costs and CO2 by moving to biomass from oil. This would allow them to utilise their own wood fuel supply from the Estate’s eighty acres of woodland.
They specified a biomass district heating system, which would need to replace three oil boilers. The system would have to heat five separate buildings and a swimming pool from a single boiler and link to a solar thermal array for summer hot water.
Treco supplied and installed a single, top-of-the-range 100kW Guntamatic Powerchip biomass boiler in a district heating scheme, which replaced the three existing oil boilers. The boiler and fuel store were installed in an outbuilding located 100 metres from the main properties. All of the buildings were linked using insulated underground pipe. In the short term, a reliable wood chip fuel supply was established through membership of the Dartmoor Biomass Cooperative. Longer term, all fuel will be sourced for free from the Estate’s eighty acres of woodland, dried, chipped and stored on site.
The Estate now has the opportunity to apply for inclusion in the Renewable Heat Incentive (RHI). This will enable them to gain payments per kWh of green heat generated by submitting quarterly meter readings to OFGEM. These payments and the fuel cost saving will mean that the project will be not only environmentally, but financially rewarding.
