1. Install a ball valve on the solar hot water outlet pipe. When using solar energy, the valve opens and the electric water heater valves are closed at the same time, so that solar water can be used. used. When using an electric water heater, close the solar valve and open the electric water heater valve.
2. The solar water heater tank is equipped with auxiliary electric heating. If the water temperature is not sufficient, you can directly use auxiliary electricity to heat the water temperature, which is much faster than the heating time. of an electric water storage water heater. When the weather is bad, do not fill the solar water tank, just fill it halfway. This way the heating time will be faster, making it easier to use hot water.
If you want to connectr solar water heater and electric storage water heater, you need to buy two tees and a water valve to connect the connecting water pipe of the solar water heater to the water pipe. of the electric water heater.
3. Electric water heater refers to a water heater that uses electricity as energy for heating. It is one of the three main water heaters, alongside gas water heaters and solar water heaters. Electric water heaters can be divided into three types according to heating power: water storage type (also called volumetric type or heat storage type), instant heating type and instant heating type.
4. Solar water heater is a device that uses sunlight to heat water. Solar water heaters are divided into vacuum tube solar water heaters and flat panel solar water heaters accounting for 95% of the domestic market share. HeatersDomestic vacuum tube solar water heaters are composed of heat collecting tubes, water storage tanks, brackets and other related parts. The conversion of solar energy into thermal energy mainly relies on vacuum heat collector tubes. Pouring cold water to produce microcirculation in the water to reach the required hot water level.
