PROBLEM TO BE SOLVED: To provide a heat accumulating device in which surplus electrical power is accumulated in place of heat, the accumulated heat is taken out and utilized when a consumed electrical power is increased during the day and entirely an amount of consumption of electrical energy can be reduced as much as possible. SOLUTION: A heat source machine 1, a first pump 2 for supplying fluid to this heat source machine and a heat exchanger 4 are arranged in series in this order in a hermetically closed fluid circuit capable of circulating fluid. A plurality of pipe passages are arranged side-by-side in parallel with the heat source machine, a first pump and a heat exchanger. Each of these pipe passages is provided with a radiator 3. The heat exchanger is provided with a parallel pipe passage different from the aforesaid pipe passage. A second pump 5 is arranged in this pipe passage and a heat accumulating fluid circuit capable of circulating fluid from a heat accumulating tank 11 in addition to the hermetically closed fluid circuit is connected to the heat exchanger. |
