[0022] The roof snow melting solar heat collector A placed on roofs Q and R in this way is used for heating. The boiler B and the heat storage tank C are electrically connected via the switching valve V, and the clothes dryer D and the heating The heating medium of the heating boiler B is connected to the furniture E so that the heat medium of the heating boiler B can be supplied thereto.

[0023] As shown in FIG. 8, the heating boiler B has a pipe 30 through which the heating medium passes, and a pipe 30 through which the heating medium passes, for example. , a heater 31 that heats the heat medium in the pipe 30 using gas, electricity, etc. In this boiler, a heating medium heated via a pump 32 is connected to one end of the piping 30. A main outlet flow path 33 for outflowing the water is connected to the other end, and a main return flow path 34 for return is connected to the other end. Ru. In this example, an auxiliary boiler B1 having substantially the same configuration as the heating boiler B is installed in parallel.

[0024] In addition, the main flow path 33 includes a heat collector A1b and a heat collector A2 on the north side in this example. Branch outflow passages 35 for snow melting that communicate with each collective joint 21 of A3 are connected via on/off valves 37. The main return flow path 34 is connected to the heat collectors A1b, A2, and A3. A branch return flow path 36 for snow melting is connected to each collective joint 22 . Also, the collection on the south side A branch outflow passage 39 is connected to the main joint 21 of the heating device A1a via the switching valve V1. While connected to the outflow flow path 33, the collective joint 22 of the heat collector A1a similarly connects to the branch return flow. A channel 40 connects to the main return channel 34 via a switching valve V2.

[0025] Note that the pre-filled cutoff valve 37 senses the temperature of the heat medium in the main outlet flow path 33 and controls the temperature. A heat-sensitive on/off valve is used to close the branch outflow channel 35 for snow melting when the temperature is below a reference value. It will be done. In addition, in this example, the switching valves V1 and V2 have first and second switching valves as shown in FIG. , a motorized three-way valve with third ports x, y, z is used. Also, the switching valve V 1. V2 is normally conductive between the first and second ports x and y, and when energized operates so that the second and third ports y and z are electrically connected, and the main flow path 33 and and the main return flow path 34 are connected to the first port x, respectively, and the branch outflow flow path 39 and the branch return flow path Flow paths 40 each connect to the second port y. The switching valves V1 and V2 are shown in Figure 8. As shown by the dotted chain lines, each operating motor is connected to the power supply T via the on/off switch SW. At the same time, the power supply T is connected via a relay U downstream of the switch SW. Then, the pump 43 becomes conductive. In this example, the relay U is installed in the attic or the like. The temperature sensor S closes the relay circuit and operates the pump 43.

[0029] However, in the winter, when the switch SW is in the OFF state, the heating boiler is turned off. Activate B. As a result, the heat medium in heating boiler B is heated and the main It is fed under pressure to the outflow channel 33, and further to the branch outflow channel 35 for snow melting and the branch outflow channel 39. After passing through the heat collectors A1b, A2, A3 and the heat collector A1a, the main return flow path 3 4 and returns to heating boiler B. Also, the heat medium is the heat collector A1a, A1b, A2, A When flowing through the roofing material 3, the roofing material 5 is It heats up in a targeted and uniform manner and can melt snow on roofs. Similarly, the heated heating medium is It is supplied to the clothes dryer D and the heater E through the outflow channel 33, and can perform drying and heating. . In this example, snow melting, drying, and heating are performed at the same time, but the above-mentioned inlet valve When 37 is used as a manual on/off valve, each function can be performed independently. Also, the warmth When the chamber boiler B is enabled to operate, for example, by sensing a snowfall sensor installed on the roof. can automatically melt snow.

[0030] Also, in the summer and intermediate seasons, the switch SW is turned on and the changeover valves V1 and V 2 is energized. Thereby, the heat collector A1a is electrically connected to the heat storage tank C. At this time again The temperature sensor S senses the temperature of the heat medium in the heat collector A1a, and is sufficiently heated by solar heat. When the water is heated, the pump 43 is activated via the relay U, and the city water in the heat storage tank C is pumped. Hot water can be supplied by heating.

[0031] Further, the first and third ports x and z of the switching valves V1 and V2 are configured to be electrically conductive. In this case, the heat medium in the heat storage tank C could be heated by the stored city water. Also, the heating medium can be supplied to the clothes dryer D and the heater E, and drying and heating can be performed. .

[0032] In addition, in this example, by facing south, the solar radiation effect is high and the solar heat collection effect is excellent. Although the heating boiler B and the heat storage tank C are selectively connected to the heating boiler A1a, each The heat collectors A1a, A1b, A2, A3 are electrically connected to the heating boiler B and the heat storage tank C. Also, each heat collector A1a, A1b, A2, and A3 is equipped with a temperature sensor to prevent solar heat. By detecting the heat collector where the heat medium reaches the highest temperature, the heat collector and the heat storage tank C are connected. It may be constructed so that it is electrically conductive.
