PURPOSE:To reduce heat loss due to heat discharge at nighttime by making it possible to separate the solar heat collector from the hot water storage part and covering the upper surface of the heat receiving tank of the heat collector with a heat insulating material. CONSTITUTION:An outer box 4 contains therein a heat pipe type heat collector 5, an enclosed vessel type heat receiving tank 6 disposed to receive the heat from the heat collector 5 and has fluid inlet and outlet ports, and a heat insulating material 7 covering the upper surface of the heat receiving tank 6. A solar heat collector 2 is made separable from a hot water storage part 3 provided with a hot water storage tank 14, and a heat insulating material is convered on the upper surface of the heat insulating tank 6. Hence, the heat discharge of the heat storage tank 14 and the heat receiving tank 6 at nighttime is extremely small, and hence the heat loss can be reduced to an extremely small value. |
