PROBLEM TO BE SOLVED: To obtain a heating system in which heat can be delivered to a consumer and can be received therefrom by arranging the heat carrier piping to supply heat carrier vapor toward a heat storage tank and supplies a liquid phase heat carrier toward a vapor generator. SOLUTION: Vapor saturated by a heat carrier for carrying heat to individual heat storage tanks H is supplied from a vapor generator 12 generating heat carrier vapor or gas phase vapor with heat generated from a fuel cell cogeneration system 10. More specifically, heat carrier vapor (saturated vapor) generated from the vapor generator 12 is fed, by its own pressure, from horizontal piping L-H and vertical piping L-V to respective heat storage tanks H,... through branch piping L-V thereto. Since a carrying facility, e.g. a pump, is not required, varying power required in hot water circulation system, for example, is eliminated. Furthermore, adverse effect of the distance between a heat source and a consumer is reduced significantly as compared with a hot water circulation type. |
