<p>PURPOSE:To obtain the hot-water of objective heat-up temperature substantially every day at an objective heat-up time by a method wherein a fluid temperature in a hot-water reserving tank upon starting operation is detected and an objective heating capacity is operated from a temperature difference between the detected temperature and the objective heat-up temperature and a heat collecting time from the starting of the operation to the objective heat-up time. CONSTITUTION:The inlet and outlet temperature of a liquid heater 8 are being inputted into a main control circuit 13A from first and second temperature detectors 11, 12 and the heating capacity is being detected at all times in the main control circuit 13A by employing a temperature difference between them and a preset amount of flow of water. The objective heating capacity is operated in the control circuit 13 by the temperature difference between the fluid temperature in the hot-water reserving tank upon starting the operation, which is detected by the third temperature detector 15, and the objective heat-up temperature and the heat collecting time from the starting time of operation to the objective heat-up time while the objective heating capacity, thus operated, is memorized in the main control circuit 13A. The revolving number of a compressor 1 is controlled in accordance with the change of atmospheric condition so as to obtain the objective heating capacity being memorized in the main control circuit 13A.</p> |
