Abstract: The energy performance of an electrically driven heat pump in a typical installation has been estimated for three locations in the United Kingdom. Comparisons made of the heat pump performance with electric resistance, oil and gas heating systems using an annualised life-cycle cost method of analysis showed that the heat pump offers economic advantages over the electric resistance heaters and the oil-fired boiler, but is not an economic alternative to the gas-fired central-heating system. To become competitive with gas-fired boilers, either the capital cost of the heat pump must be substantially reduced or its seasonal coefficient of performance increased by about 50%. A heat pump can be economically attractive when it is integrated into existing fuel-fired central-heating systems or when it is used with thermal storage and run on economy 7 electricity.
