2. Add water to operate the solar water heater, add cold water to the water tank, open the cold water valve and temperature regulating valve, and input cold water into the water tank through the supercooled water pipe, cold water valve, temperature regulating valve and upper and lower water nozzles. When water overflows from the overflow pipe, the cold water valve is closed and the water supply is finished.
3. Take a bath with hot water. When the water temperature in the water tank reaches the bathing temperature, open the hot water valve, the temperature regulating valve and the nozzle to make warm water flow out for bathing. If the water flowing from the nozzle is too hot or too cold, adjust it through the temperature regulating valve and cold water valve until the water temperature flowing from the nozzle is appropriate.
