Consumers should pay attention to the following aspects when purchasing air energy water heaters: Compressor As the core driver of the air energy water heater, when selecting the air source water heater, we must pay attention to the compressor brand it uses. The domestic market adopts world-class brand-name compressors such as Panasonic, Toshiba and Mitsubishi. The commercial market is currently better in the US Copeland and Japan Matsushita compressors. In addition to the brand, it depends on its heat, rated power and the corresponding tank capacity ratio. 2. Insulation layer If an air-energy water heater does not have good insulation, it is not a true air-energy water heater. The air energy water heater is a heat storage type water heater with a large water output, and the water temperature is generally set at 45 ° C - 55 ° C. Most air-energy water heaters have a temperature-maintaining function. For example, if the water temperature is set to 45°C-55°C and the temperature is higher than 55°C, the machine will stop automatically and stop heating. If the water temperature is lower than 45°C, it will automatically start to heat up and make the water temperature of the tank. Keep above 55 °C. Water heaters with poor water tank insulation will often start heating due to large heat loss. The high-quality air energy water heater insulation layer will be relatively thicker, and the imported polyurethane material is used, and the mature foaming process is used to make the hot water in the water tank cool down, which saves energy, and saves a lot of electricity invisibly. (The temperature setting data is for reference only) 3. Liner The inner tank is the most important part of the water tank. At present, the inner liner of the market mainly includes stainless steel inner tank, enamel inner tank and special steel inner tank. Special steel liner: consists of a bearing layer and a leak-proof layer, separated design. The pressure-bearing layer consists of a cold-rolled steel plate leak-proof layer, a crystal coating (special synthetic polymer material), a high-temperature treatment and a steel crystal integration process, which integrates the entire inner surface and opening of the inner liner, forming one time without any solder joints or welding. Sewing, super anti-corrosion, to prevent leakage. Stainless steel liner: welded from stainless steel. It is literally understood that it will never rust, but after the metal plate has been subjected to high temperature and high pressure (1, nickel element is reduced and destroyed, 304 stainless steel contains nickel 7.5-8, its main function is acid corrosion. 2. Reduced chromium content, 304 stainless steel If it contains more than 13% of chromium, it will not rust. After high temperature welding, it will drop to less than 11%. Enamel liner: As a non-metallic material, in the case of a smooth metal without a diamond edge, the porcelain is smashed and sintered at a high tide to break into the surface of the liner. Due to the limited thickness of the enamel, the excessive thickness of the enamel seriously affects the adhesion and uniformity, is easy to leak, and the surface is not smooth and easy to scale. In summary, stainless steel liner is the best choice. 4. Coil First of all, look at the coil is not good, the best coil on the market is the oxygen-free process copper tube produced by Hailiang Group. The second is to look at the outer coil or the inner coil. The inner coil is better than the outer coil, because the copper tube is placed in the water tank and directly contacts with the water, the heating efficiency is higher, the heating time is saved, and the electricity is saved. The copper tube is outside the water tank, and the copper tube is heated first. Insulation layer, reheating water, reducing heating efficiency, also consumes electricity, contrary to the purpose of us to buy air energy and energy saving; there is a fatal problem outside the copper tube tray of the water tank, that is, the copper tube should first heat the insulation layer. When the insulation layer is in a state of high temperature and high pressure for a long time, it will re-foam and the liner will easily burst. And from the maintenance point of view, the inner coil is lower than the outer coil. 5. Water tank capacity selection The capacity selection mainly considers factors such as the family population and the amount of hot water. Usually choose 50-60 liters of water per person, for example, there are 5 people in the family. We can choose 250L or 300L incubator, because we can consider the Chinese New Year holiday, or use some hot water to wash vegetables in the winter, it is better to choose a larger capacity water tank according to the actual situation. 6. Installation location At present, air energy water heaters are divided into two types: a circular water tank and a square water tank. For ample outdoor space, you can choose a round water tank. For the outdoor space is not much, you can choose the square water tank (more beautiful), put the host outside, the water tank is placed indoors. The main unit is installed in a ventilated, warm environment for better energy savings. When purchasing an air energy water heater, it is necessary to consider whether the installation problem is convenient. Some are integrated air energy that installs the water tank and the main unit in the same metal box. Relatively speaking, the air can be easily installed, the manufacturer has higher production cost, and of course the price is also It is much more expensive. It is especially important to note here that the integrated air energy enclosure must be stainless steel. 7. Brand service Consumers must understand the quality and after-sales service of the product before purchasing the machine. Currently, the air-energy water heater on the market is guaranteed for two years. 8. In the purchase, you need to consider the following precautions: (1) Appearance inspection: the outer surface baking varnish should be uniform, the color is bright, no detachment, no dent or serious scratches, squeezing marks, etc.; the outer shell is preferably a fluorotitanium plate. It is recommended to use stainless steel as well, do not choose color plates! (2) Strictly guard against counterfeit and shoddy products, it is best to find the manufacturer directly. (3) The accessories must be complete. (4) Check the power plug: The wiring should be firm, and the line is of course rough. If it is too small, it will heat up for a while, and even if it is turned on, it will cause a fire due to overheating. (5) Whether the power-on test and the constant-temperature performance check indicator light are on, and whether the machine is user-friendly or not requires no one to open normally. With or without overheat protection, the defrosting is good. (6) Noise: The noise of the heat pump water heater is as small as possible. (7) If the water heater has magnetization or ion activation, the effect is better. Our radiation pine board has a smooth surface and clear texture. Strong load-bearing capacity, manufacturers have an advantage in direct selling prices.
