Solar Net HC The face of many Solar water heaters Brand, often at a loss and a loss in the market Sell Solar Water heater There are many kinds and types of solar collectors according to points, can be divided into vacuum tube and a plate; by structural points can be divided into integrated and split; divided by production process can be divided into pressurized and non-pressure type. Currently, the most common type of household most non-pressure vacuum tube solar water heaters. The face of dazzling water heater market, consumers often are , I do not know how to choose now to tell you about the focus on the purchase of solar water heater, the first choice for a good brand and reputation with excellent product. Advantages: economy, Energy , Environmental protection , Safe and convenient water supply capacity, long service life. With auxiliary electric heating function of solar water heaters, solar-based, energy supplement, so that the use of solar water heaters can weather the whole year. Disadvantages: high price, installation complexity, compared to electric water heaters and gas water heater is more difficult to maintain. Purchase: 1. Watch brand. To select a specialized manufacturer of products, best quality brand, so it may have good quality and excellent after-sales service system and commitment. 2. Look at the quality of vacuum tubes. Water heater vacuum tube is a key component of vacuum tubes are under the same condition, the amount of heat, directly affecting the level of water temperature. Choose to carefully observe the coating on the glass vacuum tube, its color is usually black, dark blue or dark gray color uniform coating of good quality, Membrane Layer no scratches, no peeling or shedding phenomenon, there is no glass stones, pieces placed upright support, not loose. 3. Look at the insulation layer and the liner material selection, process technology. Solar water heater in the tank shell and the liner layer between Insulation material Of hot water insulation plays a key role, with polyurethane insulation materials make up more than 15 years service life. Liner is stored hot water, preferably stainless steel plate, thickness 0.5 mm. In short, consumers should choose imported polyurethane, water tank insulation layer thicker. Because the water heater insulation, and liner all in-house, consumer easy to see, so choose a good market reputation, product quality, performance, and service products will have better protection. 4. Look hot performance. The higher the water temperature is not a tank, it shows better thermal performance, while the average daily efficiency as high as possible to the average heat loss coefficient as low as possible. Second, water heater pressure test to see whether the pass, not a standard pressure test up easily lead to water heater leaks, waste water and can not use both. 5. See Support. Stent should have sufficient strength and stiffness. 6. See reflector design. In the purchase of products should pay attention to whether the design of reflectors can take full advantage of the vacuum tube of the absorber, the maximum degree of vacuum can be light. 7. The key technical issues, how to identify the out of consumption (1) vacuum tubes in different colors, because the absorbing layer, and the effect is also different; (2) reflectors are not used by most companies, since the use of a period of time, the reflectors become decorations, too much dust, no effect, but also from the wind angle, does not support with reflectors; (3) storage tanks are not the insulating layer thicker, the better to achieve the critical thickness after re-insulation thickness of no use. (4) water tank plate thickness, the non-pressure tanks, 0.4mm is almost universal standards of second-tier manufacturers have been able to ensure the service life of water heaters, but why 0.6mm of it, it was all brand-name products, prices are also expensive, costs that your selling price than others 50%. Note: Consumers should be careful to buy only the original host but not the standard fittings and pipes, "semi" solar water heaters. This causes the quality may not tell in a short time, but after the winter freeze, the summer sun, the problem will focus on the outbreak.
