Hello, would you like to ask which solar water heater vacuum tube manufacturer is best? The vacuum tube of the solar water heater is made of Linorite. Because Linorite is an enterprise dedicated to the research and development of solar vacuum collector tube products, its brand reputation is very good and its quality is guaranteed, so the solar water heater vacuum tube is Linorite.
How much heat can the vacuum tube of a solar water heater produce in one hour?
The function of the vacuum tube of a heater -Solar water is to absorb heat. sunlight to heat the water.
The solar vacuum tube is the heart of the solar water heater. Its structure is like an elongated thermos bottle. There is a void between the inner and outer layers. The surface of the inner glass tube is covered. a spectrum selective absorption coating using a special process used for absabsorb the energy of solar radiation as much as possible.
After being irradiated by sunlight, the photons strike the coating and the solar energy is converted into thermal energy. Water absorbs heat from outside the coating, water temperature increases, density decreases, heat increases. water rises and cold water with higher density decreases. The hot water is always in the upper part, i.e. in the water tank.
Detailed informationDaily maintenance
1. When installing a solar water heater, there may be a smell of dust or oil in the water pipe. When you use it for the first time, you can open it. tap to remove debris first.
2. The water stored in the solar water heater should be discharged regularly depending on local water quality conditions. Drain time can be selected in the morning when the temperature of the cadapter is lower.
3. The surface of the solar water heater should be wiped regularly depending on the amount of dust in the area. It can be cleaned when it rains. Keeping the water heater surface clean can get higher heat. collection efficiency.
4. When hot water is not used for several consecutive sunny days, the hot water temperature will be very high. When using the solar water heater, please turn on the cold water first, then turn on the cold water. hot water to avoid burns.
5. There is usually a filter device at the outlet end of the faucet. Scale and debris in the water line accumulate on this screen. It should be removed and cleaned regularly to increase water flow. smooth exit.

The vacuum tube of the solar water heater can generate2.42 kWh to heat in one hour. For a 58mm x 1800mm vacuum tube, when the thickness of the collector insulation layer is 5cm, the illumination area is about 0.093 square meters. When the thickness of the collector insulation layer is 10cm, the lighting area is about 0.090 square meters. to say, when the collector insulation layer is 10cm, the lighting area is about 0.090 square meters. When the thickness of the insulation layer of the casing is 10cm, the heat collected amount of a single 58mm x 1800mm vacuum tube is only 96.77% when the thickness is of 96.77%. of the insulation layer of the header is 5 cm. Assuming that the amount of solar radiation per square meter is 1 kWh and the heat collection efficiency of vacuum tubes is 52%, a collector with 50 tubes can absorb 2.42 kWh of heat in 1 hour when the thickness of the collector insulation layer is5 cm. it measures 10 cm, it can absorb 2.34 kWh of heat in 1 hour, which represents a total difference of 0.08 kWh.
