The property, a former barn with a Corfe stone slate and timber construction, is located off the gas grid and the owners were reluctant to consider oil as a heating source due to its fluctuating price levels and need to regularly replenish the tank. Owner Catherine Mittins instead approached Dorset based renewable energy specialist NGPS to discuss the possibilty of fitting an air source heat pump.
NGPS recommended a Danfoss DHP-AQ air source heat pump, which has a high seasonal performance, contemporary aesthetics and low noise levels. The company specified a 9kW system, which would work in conjunction with a 10 kW solar photovoltaic system on the roof, offsetting a large proportion of the heat pump’s electricity costs.
NGPS installed the cottage with underfloor heating to both the ground and first floors, as well as a hot water cyclinder. The owners were able to take advantage of the Renewable Heat Premium Payment, which provides £1,250 towards the cost of the heat pump.
