<p><P>PROBLEM TO BE SOLVED: To increase efficiency for storing heat in a hot-water storage tank and shorten time until space heating becomes effective even without any auxiliary heat source. <P>SOLUTION: A power generation heat using system is provided with a power generator 20 generating electric power and power generation heat, the hot-water storage tank 44 having an upper part water out port 44c and a lower part water out port 44d, heating front water passages 4a, 4b, 4c, 4d connected with the upper part water out port 44c and the lower part water out port 44d to feed hot water in the hot-water storage tank 44 into the power generator 20, and a change-over means 62 for making either of the upper part water out port 44c and the lower part water out port 44d effective. It is provided with heating rear water passages 5d, df returning hot water heated in the power generator 20 into the hot-water storage tank 44, heating machines 80, 82 utilizing heat medium for heating, and circulation passages 86, 84 for heating for circulating the heat medium for heating in the heating machines. It is provided with a first heat exchanger 68 performing heat exchange between the heating front water passage and the circulation passage for heating and a second heat exchanger 69 performing heat exchange between the heating rear water passage and the circulation passage for heating. <P>COPYRIGHT: (C)2004,JPO</p> |
