PURPOSE:To make it possible to store heat for a long time, by a method wherein a group of water tanks are formed in a coaxial multi-layer structure, and for each water tank surrounding the center water tank, latent heat material is filled in the gap between the wall having heat-aiding material and the heat insulator, and a heat divider is provided at the bottom of coaxis of the group of water tanks. CONSTITUTION:Water is poured from water supply pipe 25 into water tank A, and a proper amount of water is stored in water tank A, water tank B and center water tank N. When th temperature of heat collector 5 rises and temperature difference relay THS operates, hot water is ejected from the ejection port of return flow pipe 6 by pump P1. The hot water collides with buffer plate 13, and instead of flowing directly into center water tank N, is disperses at center frame 7 and reaches the uppermost part N' of frame 8. Here, if the inner temperature of N' is higher than the inner temperature of N, it goes up into N chamber. But, if the inner temperature of N' is low, it flows into outer water tanks in succession and raises their temperatures successivly. By the melting of the latent heat material of each water tank, heat is accumulated. Consequently, the center water tank is maintained at relatively high temperature at all times, so that it is possible to store heat for a long time. |
