Abstract

PURPOSE: To reduce the overshoot of hot water temperature by parallell-connecting two water heaters, disposing a circulation pump in the return pipe, disposing a water flow rate sensor upstream of the joint of the supply pipe and the return pipe, and disposing a flow rate regulator in the water line of one of the water heaters.
CONSTITUTION: When a hot water tap 6 is opened, water is fed through a supply pipe 4 and detected by a water flow sensor 15. If a warming circulation operation is under way at this time, the electric supply to an electric heater 10 and a circulation pump 9 is suspended, and, upon detecting a water flow greater than the minimum operating flow rate by a water flow rate sensor 22 in a first water heater 2, the heating is started. A flow rate regulator 13 disposed in a bypass pipe 12 is controlled to a target temperature which is set by a remote controller. Then, hot water heated by the first water heater is mixed with water supplied through the bypass pipe 12, and the mixed hot water at the set temperature is delivered by regulating the flow rate based on the detected temperature by a temperature sensor 14. When the flow rate detected by the flow rate sensor 15 becomes greater than the set flow rate, a flow rate regulator 35 is opened to cause water to be supplied to a second water heater 3 as well to heat up to a temperature higher than is set by the remote controller. Therefore, the overshoot of hot water temperature can be reduced.
