Just lighting the black iron plate can reach 60 or 70 degrees in summer, and only 30 or 40 degrees in winter. If you add high temperature oil to the solar collector tube, it can heat it to boiling. . Because the collector tube has good thermal insulation performance and high efficiency. Blue film is a selective absorption coating with high absorption capacity and low emissivity, fully absorbing solar thermal energy and, coupled with vacuum insulation, it can reach very high temperatures.
Two to three hours. The rate at which the water temperature of the solar water heater increases is related to the temperature, light intensity and capacity of the water heater. In hot summer, it can reach 60 or 70 degrees in two to three hours. the temperature is very low and there is no sunshine, the water temperature in the solar water heater will be difficult to increase. The heatffe-solar water is a device that converts solar energy into thermal energy, heating water from low temperature to high temperature to meet people's use of hot water in life and production.
