Air Heat Pump Water Heater Selection Guide

Air Energy Heat Pump Water Heater Selection Guide Air can be used as a new type of water heater, attracting many customers with its huge advantages. However, customers are very upset when purchasing, do not know what kind of air energy water heater is really high-quality products, because from the product appearance, the brand does not seem to have significant differences. The purchase of home air energy heaters can be started from the following aspects:

First, brand service selection Consumers must understand before the purchase of the brand in the city's service quality and product quality reputation. The brand product quality is better, after-sales service also has certain protection, and can enjoy on-site installation, long warranty, lifetime maintenance, and a series of services. But the brand is generally more expensive than the no-name brand, do not buy the most expensive, only to buy the best, you can choose to enjoy the on-site installation, long warranty, lifetime maintenance, and a series of services!

Second, constant temperature insulation function 1, constant temperature function: The constant temperature function can guarantee the water does not appear the hot phenomenon while bathing, but also may avoid the scald accident occurrence. At present, the state-provided hotel class water heater safety heat temperature is about 55 °C. The water temperature people use for bathing is generally more than 30 degrees.

2, insulation function: If a water heater insulation does not have a good insulation function it is not a true sense of the water heater, water heater insulation box at the temperature of 15-20 °C, the water temperature in the water tank at 55-60 °C Under the conditions, the 24-hour temperature drop cannot exceed 4°C. Therefore, it is extremely important to choose a water heater, which can virtually save a lot of electricity.

3, magnetization or ion function: If the water heater with magnetization or ion activation function, improve the human health function is an unexpected gain.

Third, the choice of capacity of the capacity of the heat preservation water tank mainly considers the family population and the hot water usage and other factors. Generally choose 50-60 liters of water per person, for example, there are 5 people in the family. We choose a 250L or 300L incubator, because it is considered better to have a larger capacity water tank based on the actual situation.

Fourth, whether the maintenance is convenient to buy water heaters to take into account the convenience of future repairs, generally people prefer to choose one machine, from a professional point of view, one machine in the maintenance when the ratio body machine trouble, maintenance and customer is not in the future Not facing things. Therefore, it is recommended that if the place where you install the water heater in your home is not particularly small, it is recommended to use separate machines. The so-called split machine is a separate host from the water tank. The all-in-one machine is equipped with the water tank and the main unit in the same metal box.

Fifth, energy efficiency is simpler than the so-called energy efficiency ratio is the ratio of the heat produced and the amount of electricity consumed. Since the average annual cost of an air-to-energy water heater is really lower than that of all other water heaters (including solar water heaters), its superb energy-saving performance is also highly favored by people. Many people see whether energy efficiency is better or better. Here, we solemnly remind consumers that we must not use this indicator to judge the quality of water heaters because many businesses intentionally exaggerate their energy efficiency ratios when publicizing their effectiveness. For example, a domestic brand declares that the energy efficiency ratio of its products can reach 6.0. The reason for the above is that it is not based on the average ratio of one year, and it is advertised based on the highest energy efficiency ratio of the water heater in the high temperature environment. The energy efficiency ratio of the general industry is calculated by the average of one year. In Guangdong, most standards are 15 to 20°C. At this temperature, the energy efficiency of the machine is generally around 3.5-4.5. The best way is to ask the merchant for a COP graph, fill a box of water, and then read the meter's reading to determine if the other identified energy efficiency ratios are true. Practice is the sole criterion for testing truth. Of course, this is a bit complicated. As for the volume of water, all brands are generally the same.

When purchasing key air-energy water heaters, key points to note are several core components that are related to product quality. Among these, the most important thing is: the compressor brand, the tank liner, the coil material and the unit configuration, which require special attention. At the same time, a longer after-sales service commitment is a reflection of the confidence of manufacturers in product quality, and it is also a worry-free protection for users during product use.

1. Compressor: As the core component of the heat pump compressor, the household machine compressor brand is Sanyo, Meizhi, Mitsubishi for high quality, while the industry uses domestic air-conditioning compressor, the unit performance and life can not be guaranteed.

2. Coil: It is best to use copper tubes, and high purity can effectively guarantee the thermal conductivity and service life of copper tubes. Some of the industry uses alloyed copper, and its corrosion resistance and thermal conductivity are significantly lower than that of copper. There are also stainless steel coils that can effectively prevent corrosion.

3, the liner: the crystal liner, also known as the special steel liner is the best, anti-leakage layer and pressure layer separation design, the inner wall of a special synthesis of polymer materials sprayed by high temperature processing and steel crystal integration process, the entire The bile surface is completely free of any welds and effectively prevents scaling. Different from ordinary stainless steel inner liner, it is stronger in corrosion resistance and high pressure resistance. In the industry, common stainless steel liners are used, and the welded parts are easy to rust and perforate, which may cause water leakage.

4, Shell: The best imported fluorine titanium plate material, marine materials, more corrosion-resistant, to ensure that the product does not fade in ten years and paint off phenomenon, followed by 304 stainless steel; the industry is mostly metal paint, for the current paint technology Even if it is Mercedes-Benz, BMW's paint still has the problem of shedding.

5, unit configuration: The best 1:1 gold configuration, high-power heating faster, effectively guarantee the life of the compressor. Some products in the industry are equipped with large-capacity water tanks for small-power main engines. Such small horse-drawn carts keep the compressors running, which directly leads to shortened lifespan of air-heated water heaters.

6, after-sales: At present the general air power manufacturers home machine warranty is one year, the engineering machine is two years. Air energy water heaters are durable consumer goods. The normal service life is 12-15 years. If the warranty period is not long enough, it will be repaired in two or three years. Each time you spend five or six hundred dollars, you can buy a brand that is too cheap, and it will be expensive to use in the future. , And bring a lot of trouble, it is best to directly buy manufacturers to buy better.

In the purchase, you also need to consider the following considerations:

1. Appearance inspection: The outer surface of the paint should be uniform, bright color, no shedding, no dents or serious scratches, extrusion marks, etc.; shell is better with rust-proof steel, such as 304 is best. Almost the use of domestic cold rolled steel paint. This kind of box is cheaper, but it tends to rust.

2, to prevent fake and shoddy products, generally to the manufacturers or manufacturers authorized to buy the best agent.

3, the attachment must be complete.

4, check the power plug: wiring to be solid, the line is of course rough is better. If it is too small, the electricity will heat up for a while, even after the long room is opened, a fire may occur due to overheating.

5, power test, temperature performance check: first look at the indicator light, the machine is humane settings do not need to go to normally open normally off. With or without overheat protection, the defrost is good.

6. Noise: The noise of the air energy heat pump water heater is as small as possible, generally less than 55 decibels.
