Abstract

The thermodynamic and economic performance of a heat pump combined with a water heat store has been examined. The thermal store contains electrical resistance heaters which can boost the water temperature to 95°C. By utilising the off-peak tariffs for electricity it has been shown that the heat pump/heat store can compete economically with conventional central heating systems, based on an oil-fired boiler, a coal-fired boiler, or night storage heaters. To stand comparison with gas central heating, however, the cost of gas would have to increase by 6%, the capital cost of the heat pump/heat store be reduced by 20%, or the seasonal performance of the heat pump/heat store be improved by 17%.
