When purchasing a solar water heater, you should pay attention to the following four points:
1 Look at the quality of the vacuum tube . The vacuum tube is a key part of the water heater. When purchasing, you should carefully observe the coating of the glass tube inside the vacuum tube. Its color is usually black, dark blue or dark gray. A good quality coating has a uniform color, no scratches, peeling or peeling on the film, there are no stones on the glass and the backings are placed correctly and will not come off.
2. Look at the insulation layer and the inner tank. In process technology, there is a layer of insulating material between the outer shell and the inner tank of the solar water heater tank, which plays a very critical role. role in hot water insulation. It is made of polyurethane. The lifespan of insulating materials can reach more than 10 years. The inner tank is where the hot water is stored and its thickness is approximately 0.5mm.
3. Look at the support design. The bracket supports the heat collector and the insulated water tank. It must have a solid structure, high stability, wind and snow resistance, aging resistance and no rust. The material is usually stainless steel, aluminum alloy or powder-coated steel.
4. Select the water tank capacity. Generally, domestic bathing water is the lowest: if domestic water includes cooking, the total water consumption can be estimated based on the per capita water consumption of 40L; The water temperature of domestic solar water heaters in winter is generally calculated at 50 to 60 degrees, converted to the water capacity of the water heater. Actual purchase depends on condition of water heater.
How to analyze the quality of energye solar
Huangming solar coating uses SUS304 stainless steel coating and launches unique PP nano-coating for areas with poor water quality. . Huangming solar coating uses fully automatic seamless argon arc welding. There are no soldering points. Air drying indicates whether the insulation layer outside the water tank will be alienated. Huangming insulation layer uses 40kg soaking per cubic meter. minutes of aging treatment, there is no problem with air drying for 15 days
1. The internal temperature of the solar water heater is relatively high, the life of the stainless steel heating tube is 1 year, and the life of the copper alloy heating tube is 2-3 years, while the best Inglai 800 heating tubes have a lifespan of 8 to 15 years.
2. Electric Glass Heating Tube: When fired dryat high temperatures, the glass will soften, warp or even be damaged.
3. Stainless steel electric heating tube: poor corrosion resistance and short service life.
4. Electric aluminum heating tube: poor corrosion resistance and short service life.
