Three links in the purchase of solar water heaters
As the weather turned cold, the solar water heater market began to be bustling, with a dazzling array of brands, chaotic prices and a variety of pleasing service commitments that consumers could not overwhelm. How can we rationally purchase a good solar water heater? Sina home reviewers suggest that consumers can choose a safe and easy-to-use solar water heater from the three aspects of hot water demand, standard life and installation service. Good winter is the standard Consumers buy solar energy in order to use domestic hot water, especially in winter, but according to media reports, 70% of solar water heaters purchased by consumers have failed in winter or rainy days. These products use inferior vacuum tubes. The heat collecting capacity is poor, the heat preservation effect of the water tank is weak, and the hot water is not produced when the sun is shining in the winter. A qualified solar water heater must be used to produce hot water in winter, and the insulation effect is good. Pay attention to long-term use The second key factor in identifying solar water heaters is the life expectancy, not the simple service life. Some solar water heaters are still not damaged on the roof, but the heating effect is very poor, the product has not been used for a long time, but it has not achieved the normal use effect. Production quality, production technology, installation services and other factors directly affect the actual service life of solar water heaters. Some inferior solar water heaters use inferior vacuum tubes, low vacuum, and a large amount of impurities and water vapor remain in the tubes. Within two or three years, the film layer has aged and fallen off, and it is unable to absorb enough heat; and the selection and processing of the inner liner and the water tank insulation layer Also cut corners, shoddy, shoddy, inferior materials, after a few months, the insulation effect plummeted, basically no insulation after one or two years. Although such solar water heaters are low in price, they not only have a very short life, but also have a very limited service life. On average, the price paid by consumers is not low. Standardizing services is the most critical As a special heat collecting device, solar water heaters are not the same as home appliances. They are only a semi-finished product after delivery, and need corresponding installation and after-sales service. If the installation and after-sales service are not in place, it will seriously affect the use of the product. Therefore, consumers must thoroughly review the service capabilities of the manufacturers before purchasing solar water heaters. At present, some non-standard production and operation enterprises on the market, while selling products, are also slickly indicating the warranty period and even promised a lifetime warranty to consumers. However, when consumers really have problems finding a door, it is not that the phone can't get through, or that people go to the building, causing consumers to complain. Moreover, these companies often use inferior fittings when installing products, and it is easy to freeze or freeze cracks in winter, causing the paralysis of the entire solar water heater. Therefore, the tempting service promise does not make any sense if it is not guaranteed. It is more like a commercial deception. Consumers should stay away from such products.
