PURPOSE:To increase the heat accumulating efficiency as well as to make a structure and an embedding work of the apparatus under the ground easily, by constituting a heat exchanger laid underground of a building so as to form a heat accumulating and snow melting circuit, a room heating circuit, and a hot-water supplier preheating circuit, a respectively. CONSTITUTION:Heat exchangers 2A-2C are laid underground of a building. These heat exchangers 2A-2C form a heat accumulating and snow melting circuit 5 together with a heat exchanger panel 1, provided on the roof of a building, for the purpose of both solar heat accumulating and snow melting works; a room heating circuit 9 together with a heating appliance 13 provided to the inside of a building; and a hot-water supplier preheating circuit 10 together with a hot-water supplier 17 installed in the building, respectively. The heat exchangers 2A-2C laid underground the building consist of coiled pipings which form an earth heat-accumulating tank 8 to make an earth 3 a heat accumulating member, so that a work to lay a large tank under the ground is not needed. As a result, a burying work of the heat exchangers can be easily performed, and the earth which exists infinitely can be efficiently utilized as a heat accumulating member, and the expected heat accumulating effect can be obtained by determining the depth to bury the heat exchangers. |
