PURPOSE:To make a circurating pump or a compressor unnecessary by a method wherein a conduit pipe between an evaporator and a condenser is made as a gaseous working fluid supplying route, and a check valve is installed in a working fluid feeding route between the gaseous working fluid supplying route and a pressure equalizing route is installed in the gaseous working fluid supplying route or between the working fluid feeding route and the working fluid reservoir. CONSTITUTION:When working fluid in the working fluid reservoir 22 is heated by a heater 23, the vapor pressure in the reservoir rises, and working fluid in the reservoir goes up through a fluid ascending route 4, a pressure equalizing route 14 and a fluid descending route 4, and hot water is obtained. When working fluid in the working fluid reservoir 22 decrease, and the lower end of ascended part of working fluid in the ascending route 4 comes upper than a float valve 14, working fluid at the lower part than a float valve 15 in the pressure equalizing route 14 drops in the working fluid reservoir 22, and the float valve 15 is opened and the pressure in the working fluid reservoir 22 and the pressure in the condenser 3 are equalized, and working fluid in the fluid descending route 6 flows down in the working fluid reservoir 22 and returns to the original condition. Such motions are performed repeatedly. |
