<p>PROBLEM TO BE SOLVED: To make a trial run for filling a bath with hot water even in a state water in a storage tank is not fully warm by controlling the mixing rate of water and hot water by a control part, and by providing the control part with a trial-run mode for filling the bath with hot water by using only water. SOLUTION: A switch for a trial run for filling a bath with hot water of an operation part 32 is operated for sending a trial run command to a control part 31, and a trial run mode that controls an electric valve 4 for mixing hot water with water by the control part 31 is set so that it is fully opened only at a water side and executes an action for filling the bath with hot water. Then, the switch for filling the bath with hot water of the setting equipment of the operation part 32 is turned on, the electric valve 4 for mixing hot water with water is activated for opening the switch of a solenoid valve 28, and hot water in a storage hot water tank 1 passes through an upper mixing valve hot-water supply pipe 14 for supplying to the electric valve 4 for mixing hot water with water. On the other hand, water from a water source is passed through a mixing valve water supply pipe 13 from a water supply pipe 11 and is supplied to the electric valve 4 for mixing hot water with water. The supplied water is mixed with the supplied hot water by the electric valve 4 for mixing hot water with water, passed through bath piping 15, and is supplied into a bath 2 via a bath adapter 3, thus the bath is filled with hot water.</p> |
