PURPOSE:To obtain a heat accumulating apparatus utilizing solar heat, which is capable of supplying hot water promptly and can be installed with case, by disposing a heat exchanger in a heat accumulating tank, and providing a fluid passage switching means and a conduit for circulating a heat accumulating medium in the heat accumulating tank to the heat exchanger by means of a single circulating pump without passing the heat accumulating medium through a solar heat collector. CONSTITUTION:Heat is accumulated by circulating a heat accumulating medium 3 to a solar heat collector 4 by operating a circulating pump 8 when the solar rays are sufficiently available. By use of a heat exchaning conduit 7 connected to external apparatus, superfluour solar heat can be recovered directly in a heat accumulating tank 1 and heat is accumulated simultaneously with utilization of the solar heat. In case of utilizing accumulated heat in the night or on a cloudy day, the heat accumulating medium 3 having accumulated sufficient heat is circulated only to a heat exchanger 5 by means of a fluid passage switching means 9 for exchanging heat with the external apparatus. |
