<p>PURPOSE:To prevent excess or insufficiency of hot water by obtaining supply hot water consumption heat quantity based on a temperature of hot water and a heating temperature in a hot water storage tank at the time of ending hot water supply of one day, storing the heat quantity for several days, dividing a maximum value by a total volume of the tank, and correcting it by a temperature of supply water to calculate a target heating temperature. CONSTITUTION:A hot water storage tank 1 is fully filled with water, heated up to a heating temperature Th set in response to a water temperature T0 by a condenser (heating means), heated to a bathing temperature, and hot water is discharged from the top of the tank 1 through a hot water supply tube 8 for use. At the time of ending hot water supply, a controller 9 inputs warm water from warm water sensors 11a-11f, calculates supply hot water consumption heat quantity of one day by the temperature Th and volumes of installations of the sensors 11a-11f, and stores them in a memory 12. The maximum heat quantity for storage is discharged, and divided by the whole volume of the tank 1. A constant responsive to a supply water temperature detected by a water temperature sensor 10 is added to the result to obtain a target bathing temperature. The heating temperature for next one week is controlled according to the target bathing temperature.</p> |
