A BRIGHOUSE firm has won the contract to supply new-style home heating in Kirklees. The heat pumps work like a refrigerator in reverse by extracting heat from the outside air. They produce hot water that can then be pumped around the home to heat radiators. Heatking, based at Armytage Road, Brighouse, will supply 30 which are to be installed free in selected homes in a scheme by Kirklees Energy Services. The pump's maker claims the technology is highly efficient.
