Solar water heater without the sun how to do?
Solar water heaterThe utility model relates to a solar water heater, which is a device for converting solar energy into heat energy, which is used for heating water from low temperature to high temperature, so as to meet the requirement of hot water use in people's life and production. According to the structure of the solar water heater is divided into vacuum tube solar water heater and flat type solar water heater, mainly vacuum tube solar water heater, occupy 95% of the domestic market share. Vacuum tube type solar water heater is composed of a heat collecting pipe, a water storage tank and bracket and other related parts, converting solar energy into heat energy mainly rely on vacuum tube, vacuum tube using the principle of cold water sinking floating, the water circulation and desired hot water.
2, now the solar water heater, taking into account the rainy weather, the general installation of electric auxiliary heating device, in the absence of the sun, you can use electricity to heat.
Solar water heaters do not have to worry about the sun:1, there is no sun weather, the water in the water heater is not heated, naturally not hot, but, if one day the water has not run out, it depends on the function of water tank insulation, good insulation, high temperature. On the other side. Such as Zhejiang in the winter is very cold, but the sun, three or four hours after the sun, the water temperature is also fifty or sixty degrees, is to rely on the preservation of the water tank.
