Every family has a water heater, but when buying a water heater, some people will buy a solar water heater, while some people will choose to use an air energy water heater. How to choose an air energy water heater? The points for attention in the purchase of air energy water heater are:
1. The higher the water temperature heated by the heat pump, the more hot water is obtained
The heating water temperature of the heat pump refers to the temperature that the water in the water tank can be heated only by the heat pump system. Why should we pay attention to the heat pump heating water temperature? Because in the actual use process, the higher the heating water temperature of the heat pump, the more bathing hot water users get, and the multi-point water supply in the central household can be guaranteed. The national standard heat pump heating water temperature is 55 ℃, and a few companies with strong R & D strength, such as a.o. Smith, can make the heat pump heating water temperature as high as 65 ℃. The experimental data show that under the same rise, 65 ℃ can output 30% more bath hot water than 55 ℃!
2. The higher the energy efficiency grade is, the more power will be saved, and the first-class energy efficiency will save 78%
The energy efficiency grade depends on the cop (energy efficiency ratio) value, which directly affects the power saving degree of air energy water heater. The energy efficiency ratio of air energy water heater reaching the national first-class energy efficiency is 4.2, saving 78% electricity. After conversion, the use cost of air energy water heater is indeed lower than that of other water heaters, and the water temperature is comfortable and constant. Therefore, energy efficiency should also be the focus of purchase. When purchasing, users can pay attention to the energy efficiency label on the fuselage to understand the energy efficiency grade of air energy water heater. The big advantage of air energy water heater is that it has low operation cost and good energy conservation, which is an important reason why the public choose air energy water heater. Therefore, when choosing air energy water heater, it is natural to choose air energy water heater with high energy efficiency; Generally, the energy efficiency ratio of air energy water heater is calculated based on the average value of one year. In South China, most of them take 15 ~ 20 ℃ as the standard. At this time, the energy efficiency ratio is generally about 3.5-4.5.
3. Select professional and brand manufacturers
Nowadays, the products are mixed. Many manufacturers of water heater will go to whichever product they see to make money. Without certain technical basic support, the products produced will not be guaranteed. It is a new product such as air energy water heater. Therefore, when choosing air energy water heater, we must choose professional and brand products, as well as brands with good reputation and good sales. At present, Meide has good domestic sales.
4. The water tank has the function of constant temperature and heat preservation
This function can be said to be an important function that takes into account the needs of customers. The constant temperature function can ensure that the water will not suddenly heat during bathing and avoid scalding. It is for families with elderly and children.
5. Whether the maintenance is convenient
Generally, there are two kinds of air energy water heaters: one machine and split machine. Now customers choose more one machine, but one disadvantage of one machine is that it is troublesome to maintain; Therefore, if the place where the water heater is installed at home is not small, it is recommended to use the split machine, which is conducive to maintenance.
6. Capacity selection of air energy insulation water tank
The capacity selection of air energy water heater mainly considers the amount of hot water. Generally speaking, each person needs about 50-60 liters of water per day. Customers can calculate according to their family’s actual population. In order to prevent visitors and other special factors, they can choose a larger water tank according to the actual situation.
7. Air Aftermarket
At present, Midea has a 6-year warranty for the whole machine. The warranty of household machines of general air energy manufacturers is two years and that of engineering machines is one year. The air energy water heater is a durable consumer product with a normal service life of 12-15 years. If the warranty time is not long enough, it will be repaired once every two or three years. It will cost 500 or 600 yuan each time. If you buy too many brands, it will be expensive to use in the future, and it will bring a lot of trouble. It is better to directly find the manufacturer to buy it.
