In Suning Appliance's Liujiayao store, only the Smith family put out an air-energy water heater prototype, and a special display board explained its working principle to consumers. Reporter noted that the same 60 liters capacity, air to water heaters are much larger than ordinary water heaters. “This is a compressor with a heat pump inside.†The salesperson knocked on the arc-shaped edge of the right side of the box, and he reminded that the grille inlet needs to maintain a distance of at least 30cm from the wall, so the bathroom should be larger. With a load-bearing wall that is more than 1.2 meters wide, it is only possible to hang this kind of air-to-water heater with a water tank and a compressor.
"There is also energy in the air? How can we save half the power?" A couple of middle-aged couples who came to buy water heaters stared at the exhibition board with suspicion. Female sales are easy to calculate, the heat pump power is only 250 watts, the water temperature in winter to 50 degrees Celsius to 5 degrees, the power consumption is 1.25 degrees; the same volume of ordinary electric water heaters, power 3000 watts, probably burning 50 minutes, The power consumption is about 2.5 degrees. In order to cope with the need for urgent hot water, air heaters and 3000 watt heating rods can be started at any time.
However, the heat pump in the end how to work, the winter room temperature is not high how to heat the water to fifty to sixty degrees Celsius, the sales will not be explained.
In Gome and Dazhong Electrical Appliance Stores, consumers can see the air-energy water heater Ariston also has a new product, but also a water tank compressor, and hit a power-saving 66% of the eye-catching ads, but the sales staff said they have not seen To the product specification, the price is not clear.
Airborne water heaters, which are intensively used for advertising in the United States, do not seem to be able to expand into the northern market. There is no way to connect prototypes in home appliance stores. A salesperson explained that the United States' home-based model in Beijing had only two large-volume products, 160 liters and 190 liters, and it was too occupied. According to reports, the two products are priced at 5,000 yuan and 6,500 yuan, respectively, belong to the family's central hot water system, generally installed in the balcony or storage floor, sales are very small.
The reporter learned that air-energy water heaters are currently more popular in the areas south of the Yangtze River. The high temperatures in the four seasons have the advantage of collecting heat from the air. Usually, split-type designs are used. The water tank is in the bathroom, and the compressor is installed outdoors like an air conditioner. “In the north, air-energy water heaters have been installed through an integrated design room to solve the problem of collecting heat in cold weather in winter. All major brands have already achieved water temperatures above 60 degrees.†Wang Lei, deputy director of the China Household Electrical Appliances Association, said The energy efficiency of air-to-water heaters is 3 times that of ordinary electric water heaters.
In developed countries in Europe, America, and Japan, air-energy water heaters are rapidly being promoted. In the United States, about 30% of water heaters use air energy units; the European Union and Australia have listed air-energy water heaters as renewable energy products and consider gradually eliminating ordinary electric water heaters; Japan has given the production, use, and even publicity of air-energy water heaters. The government subsidy, in which the use of subsidies for the average link to reach 25% of the total price, the new heating water heater has accounted for 80% of the share of heating.
Wang Lei analyzed that high prices, limited choice of brands and products, limited installation space and other factors are not the main obstacles for the promotion of air-energy water heaters in Beijing. The key is that consumers do not understand this new technology and it is difficult to accept common sense. At the same time, it lacks related support policies.

Absence of energy-saving subsidies
Energy-saving lamp promotion, ground-source heat pump air-conditioning, solar roof power generation, and contract energy management are important energy-saving emission reduction projects funded by Beijing's financial subsidies. From September of this year to February of next year, citizens can buy first- or second-grade energy-efficient televisions, refrigerators, washing machines, air conditioners, computers, and enjoy old-for-new subsidies while they have 100 to 300 yuan of energy-saving subsidies.
Why does the air-energy water heater not include the energy-saving subsidies? Energy and environmental protection center of science and technology personnel said that on the one hand is that this type of water heater has not been listed in large quantities, and the choice of space is small; on the other hand, the consumer groups are mostly families whose residential conditions are good adopting the central hot water system and enjoy their strong consumption power. Energy-saving subsidies may be controversial.
In this regard, the industry pointed out that, in theory, the performance of air energy water heaters is 4 times that of ordinary electric water heaters, and 3 times that of gas water heaters. If it is vigorously promoted, it is of great significance in alleviating the pressure difference between the grid system and gas supply. Schools, hotels, bathing centers, hair salons and other units that apply air-energy hot water systems may first adopt a subsidy policy.
Air-to-water heaters are expensive and the market is cold
“Is your home water heater replaced?†Recently, frequent air-energy water heater ads caused many consumers to curiosity. Reporters visited a number of home appliance stores found that the fourth generation of water heaters known as the air can be very rare and expensive. According to experts from the China Household Electrical Appliances Association, the energy consumption of air-to-water heaters is at least half that of conventional electric water heaters, but market promotion also requires the support of relevant policies.
