<P>PROBLEM TO BE SOLVED: To keep on power generation in such a state that a heat storage capacity to spare runs out without the need for a special heat dissipating exchanger in a power generation unit. <P>SOLUTION: When a heat storage amount in a heat storage tank 20 is the maximum (YES in Step S12), if a burner 57 is in non-combustion (YES in Step S14), a heating pump 69 is driven to circulate water in a radiating circuit 14 as a heating circuit bypassing a heating terminal 76 (Step S16). The water in the radiating circuit 14 is heated by heat stored in the heat storage tank 20 while passing through the heat storage tank 20 and the heat is radiated from a burner heat exchanger 60. Thus, even when the power generation unit 110 has no radiating means, the heat is radiated from a water heater 22, and even when the heat storage amount is the maximum, power is generated. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
