1. Firstly, as an energy-saving, environmentally friendly and renewable energy, solar water heater is a device that absorbs energy from the sun through heat collecting plates or heating tubes and converts light energy into thermal energy. . It is equipped with a water tank to convert heated low temperature tap water into hot water to meet our hot water demand.
2. Second, let's talk about why the water is not hot. If irradiation is low, it is recommended to activate the supplementary heating device with solar energy. to heat it; there is too much scale in the water tank and electric heating pipes, which prevents heat dissipation in the heating wire; there is a malfunction in the heating mode of the solar water heater or in the internal accessories of the thermostat; whatever the temperaturefrozen, the water is still not hot; there may also be too many impurities in solar energy, which affects the heat transfer effect.
3. Finally, you should clean and maintain the water heater regularly to maintain the hot water conversion efficiency. Activate the electric heating mode appropriately so that the water heater can. heat even when there is no use of light water.
