1. Add a pressure booster pump outside the water tank: In order to increase the hot water pressure, a hot water booster pump can be added to the solar hot water pipe on the roof, this which can solve the problem. the hot water problem Pressure problem.
2. Replace the thermostatic mixing valve: The principle of the thermostatic mixing valve is to use the characteristics of the temperature sensing element of the mixing outlet to push the valve core into the valve body. move, block or open the cold and hot water supply. When the cold water is blocked and the hot water is turned on at the same time, when the temperature adjustment button is set to a certain temperature, no matter how the temperature and pressure of the water inlet cold and hot water change, the proportion of cold water and hot water entering the water outlet will also change,thus keeping the outlet water temperature constant.
3. Reduce tap water pressure: turn down the main water valve of the indoor tap to a level that does not affect daily cold water use, thereby reducing cold water pressure, so both hot water and cold water can be used. When the water pressure is balanced, the hot water can also be adjusted via the mixer tap.
Precautions for using solar electric water heaters
1 When filling water when the weather is extremely hot and the temperature water is extremely high, you must use. the water supply valve to limit pressure and add water. It is strictly prohibited to add water after the water is used up. Fortunately, turn on the water before sunrise in the morning or two hours after sunset in the evening, to ensure the life of the chauffe-eau.
2. Each water heater has a vent at the top. It is normal for water to flow out when the water is full. It will stop after the water supply valve is closed. (This will not happen with water heaters equipped with temperature and water level indicators).
3. Electric heater: The power of the electric heater is 1500W. If it is used on cloudy days or in winter when the water temperature is not sufficient, do not plug it in for a long time. The power should be turned off when taking a shower. After plugging in, if the red light on the leak protection cap lights up, it means it is heating up, and if the green light lights up, it means the water temperature has reached 65°C.
4. When the temperature is not too low (7℃-5℃), after exhausting the water at night, there is still hot water (water in the vacuum tube) in the water heater, and it must be refilled with water immediately. Reduce the internal water temperature of the water heater, reduce heat loss that night, and make full use of thermal energy.
