PURPOSE:To make it possible to effectively utilize midnight power, to use a reaction material having a slow reaction speed and effectively utilize condensation heat of vapor of a material to be reacted by providing first and second heat exchangers and first and second heating bodies in the reactant parts of first and second vessels and providing a third vessel provided separately from respective vessels thereby to accommodate a fluid in these vessels. CONSTITUTION:An input is applied to a heater 10 relative to a second heating body between 3 o'clock and 5 o'clock within a midnight power time zone, thereby to heat a material 4 to be reacted within a second vessel 2 to generate its vapor. When the switching valve 8 of a connecting pipe 7 is opened, vapor passes through a connecting pipe 7 and reaches a reactant part within a first vessel 1 wherein both the vapor and the reactant react with each other to produce a temperature T2 of a high value. When the adiabatic property on the outer surface of the first vessel 1 is increased, a reactant 3 is preserved at a temperature T2 up to the daytime. In order to smoothly carry out the reactive operation, it is necessary to eliminate a part of heat of the reactant 3 at the time of an exothermic reaction, and it is preferable to close a switching valve 15, to open a switching valve 16 and to drive a pump 13 thereby to cause a fluid 20 to flow through a pipeline 19, a pipeline 22, a first heat exchanger 5, a pipeline 23, and a pipeline 18, in this order. Heat accumulated in the fluid 20 is utilized for the hot water supply and bath. |
