Commercial Solar water heater is a heating device that converts solar energy into heat energy. It heats water from low temperature to high temperature to satisfy people's use of hot water in life and production. The solar water heater is divided into vacuum tube solar water heater and flat panel solar water heater according to its structure. The main type of solar water heater is vacuum tube solar water heater, which occupies 95% of the domestic market share.
Vacuum tube household solar water heater is composed of collector, water storage tank and bracket and other related parts. The conversion of solar energy into heat energy mainly depends on vacuum heat collector. Vacuum heat collector utilizes the principle of floating and cooling water sinking in hot water to produce microcirculation of water and obtain the required hot water.
High-tech products, copper-aluminium anodized composite core or all-copper core, high surface treatment technology, good heat transfer performance, strong heat absorption capacity, large water production. The system has good heat preservation performance, large heat storage energy and water storage function. It can meet the needs of large numbers of people to use hot water centrally, and also can be used as emergency water source when water stops.
The solar water heater system operates automatically and statically without any dangers such as personal supervision, noise, pollution, leakage, fire and poisoning. It is safe and reliable, environmentally friendly, energy-saving and beneficial to the nation and the people. The utility model has the function of sewage purification, and the water source is clean and pollution-free. Vacuum tubular solar water heater has good thermal insulation and freezing resistance. Installation of large area has thermal insulation effect on floor
The advantages of commercial solar water heaters are safety, energy saving, environmental protection and economy.
Among them is the commercial solar water heater with auxiliary heating function. It uses solar energy as the main energy and electric energy as the supplementary energy, so that the commercial solar water heater can be used all the year round.

Disadvantages: Complex installation, such as improper installation, will affect the appearance of housing, quality and city appearance; maintenance is more troublesome, because solar water heaters are installed outdoors, mostly on the roof, roof, so it is more difficult to maintain than electric water heaters and gas water heaters. In the case of sunny summer days, the water temperature can reach boiling point in less than two days. If water is not used for a long time, such as traveling or traveling, keeping the water tank in a state of high temperature and pressure for a long time will promote the aging of sealing rings, accelerate the aging and shrinkage of polyurethane, sometimes the exhaust is not smooth, and the pressure is too high, which will also cause the water tank to swell.
It will scale and shorten the life of water tank. When the solar water heater is not in use, it releases the water, and then covers the vacuum tube with a cover cloth to prevent the vacuum tube from drying in the air and reduce its service life. When the cover is uncovered, the water can be used before the sun comes out. If gas water heater or electric water heater is selected, long-term use of the equipment is not good. Before use, check whether the equipment is safe, whether the work is normal, whether there is drip leakage phenomenon in water and electricity.
If everything is normal, it can be used normally. Without solar water heater for a long time, we can try to unload the collector and empty the water. If it is troublesome to unload the collector tube, the collector tube can be shielded by a color shingle, and the water should also be drained. The air temperature of solar energy will be very high, even if it is not used for a long time, it will not affect the quality of vacuum tubes.
