PURPOSE:To supply circulating water of stabilized temperature, into the side of low- temperature load by a method wherein a bypass circuit, connecting a high-temperature circuit to a low temperature circuit, is provided to control the heating of a heat exchanger by the output of a low-temperature detector provided in the low-temperature load. CONSTITUTION:A heat exchanger 2, effecting the control of heating of water circulated by a pump 1, and a tank 3, absorbing the expansion of circulating water, are provided while a high-temperature load 4 requiring high-temperature water employed for heating or drying by warm-air, is connected to the heat exchanger 2 through a high- temperature circuit 5. Further, a low-temperature load 9, connected by a low- temperature circuit 8, branched from the connecting part of the water inlet port of the heat exchanger 2 and the pump 1, and requiring low-temperature water for floor heating and the like, is provided while the high-temperature circuit 5 is communicated with the low-temperature circuit 8 through a bypass circuit 10 interposed with a checking device 11. The temperature of the low-temperature water is detected by a low-temperature detector when the low-temperature load 9 is used and the heating of the heat exchanger 2 is controlled so that a measured temperature arrives at a temperature set by a temperature setting switch 22. |
