This invention solves the above-mentioned drawbacks and prevents the hot water supplied from the solar heater from being cooled by the water in the water supply room or pumping room, and instead allows it to be heated by the high-temperature hot water supplied from the boiler. This is the purpose.

The basic structure of this idea is that a water supply chamber leading to the water pipes and a water pumping chamber leading to the water supply pipes of the solar heater are installed adjacent to each other on one side of the valve box, and a hot water supply chamber leading to the boiler is installed on the other side of the valve box. The room and a landing room leading to the downfall pipe of the solar heater are provided adjacent to each other, and the landing room is provided on the opposite side of the water supply room and the water pumping room, and is not adjacent to either the water supply room or the water pumping room. A mixing chamber is provided which communicates with the hot water supply room and the exit room, respectively.The mixing chamber communicates with the discharge pipe through a first outlet and the shower hose through a second outlet, and the first outlet and the second outlet are connected to the shower hose. The water supply chamber and the water pumping chamber communicate with each other through a water pumping port, and the water pumping port is provided so that the water pumping port can be opened and closed alternately with a switching valve, and the water supply chamber and the mixing chamber communicate with each other through a water outlet. The water outlet is provided so as to be freely openable and closable with a water outlet valve, the hot water supply room and the mixing chamber communicate with each other through a first hot water outlet, and the first hot water outlet is provided so as to be freely openable and closable with a first hot water outlet valve, and the hot water supply chamber and the mixing chamber are connected with each other through a first hot water outlet. It communicates through a second tap, and the second tap is provided so that it can be opened and closed with a second tap.

Water is supplied to the solar heater by operating the pumping valve, water is discharged by operating the water outlet valve, and hot water from the boiler is discharged by operating the first hot water valve. This is done by operating the second hot water outlet valve, and switching between the discharge pipe and the shower hose is done by operating the switching valve.

The temperature of hot water supplied from the solar heater is 30-50℃
There is only 1 in the front and back, so it is not high, and the cooling room filled with hot water is not adjacent to the water supply room and pumping room, but is adjacent to the hot water supply room, so it is not cooled by the water in the water supply room and the water pumping room.
