PURPOSE:To enhance utilization of a titled device, by a method wherein, in a device in which hot water heated by a collector is stowed in a heat accumulating tank, and a radiator is heated by hot water in said tank, a heat pump cycle is placed, and a condenser is, in a relation of heat exchange, combined with a radiator circuit. CONSTITUTION:In a device in which hot water, being increased in temperature by a collector 2, is stowed by feeding it in a heat accumulating tank 1 through operation of a circulating pump 5, hot water in the tank 1 is then fed to a radiator 3, and hot air is blowed out through operation of a fan 4, a heat pump cycle is mounted. Or, the device is constituted such that a condenser 12 is placed in a relation of heat exchange and in the proximity of a piping at the output side of the radiator 3, a coolant discharged from a compressor 11 is fed, and heat is applied to hot water in a radiator circuit 8. Meanwhile, the coolant itself is condensed, and is led to an evaporator 14 through an expansion valve 13. The evaporator 14 is installed such that hot water in the heat accumulating tank 1 serves as a heat source, and the radiator circuit 8 is adapted to be actuated by the condenser 12 serving as a heat source through switching of a 3-way valve 9. |
