Summary

In Japan, the demand for hot tap water accounts for about one third of residential final energy consumption, but most of this demand is met by direct combustion of fossil fuel. Highly efficient heat pumps for hot tap water supply have to be developed. The development of a CO2 heat pump water heater for residential use was started. A prototype was designed and made. In this paper the prototype and its performances are described. The yearly average COP under Tokyo conditions was estimated.
