PURPOSE:To realize fuel cost reduction and replenishing water saving by raising to a high temperature the regenerative hot water and warm water by the hat radiation from circulating water warmed by solar heat collecting facilities and utilizing efficiently the heat in a boiler to heat the replenishing water to a warm water and replenishing this warm water to the boiler. CONSTITUTION:A hot water storage boiler is constituted with a regenerative hot water storage boiler 1 at this lower section and a warm water storage boiler 2 which is installed at the upper section. Into the regenerative hot water storage boiler 1 part of a hot water storage pipe line 18 for storing regenerative hot water which has been used for bathing and thermally insulating it is inserted. When the circulating water which was heated by a solar heat collecting device 26 reaches a first set temperature, a circulation pump 8 operates to heat the warm water in the warm water storage hot water boiler 2. The warm water is heated to a second set temperature by a circulation circuit via a circulation pump 8 from a circulation pipe 6A, and when it reaches the set temperature is leaves the circulation circuit through which it has passed up to now and pass through a solar heat collecting device 26 which has reached a high temperature via a circulation pipe 6' and its temperature is raised by heat radiation. If its temperature does not reach a third set temperature, an auxiliary heat source machine 5 starts operation automatically and heats it to store hot water and insulate its heat. |
