PURPOSE: A heating control device is provided to automatically and conveniently operate a hot water boiler by using a temperature sensor installed in a hot water supply pipe when sunlight is not radiated and to minimize consumption of fuel. CONSTITUTION: In a solar heater or a hot water boiler, a heat storage tank high temperature sensor(2c) and hot water circulation pipes(6,6a) are installed at upper and lower sides of a heat storage tank(5). A plate heat exchanger(7) is installed at the hot water circulation pipes. A first hot water circulation pump(8) is installed in one hot water circulation pipe, and heating hot water circulation pipes(14,14a) are installed in the plate heat exchanger. A control unit(2) comprises a solar heater control unit(20a) connected with a collecting plate temperature sensor(2a), a thermal medium circulation pump(3) and a heat storage tank low temperature sensor(2b) and a hot water boiler control unit(20b) connected with the heat storage tank high temperature sensor, the first hot water circulation pump, a second hot water circulation pump(9) and a burner(13). With the control unit, hot water heated by the solar panel is heat-exchanged by the plate heat exchanger. Therefore, heating pipes are heated. |
