Why are so many air energy water heaters closed in winter?

Air energy water heater is not suitable for cold weather, this kind of water heater is not suitable for areas with low annual average temperature, cold places in winter will be very inconvenient, cold day energy consumption not to mention, heating effect is very poor, choose carefully, do not believe the layman's foolishness! Before paying for it, consult an insider.

No, this is usually sold in the winter, I don't know where you are.

Don't listen to the braggadocio upstairs, it's probably useless to say that.

My family also bought a locally produced one, and the effect is very good, so I won't say much about the brand, so as not to be suspected of advertising.

Generally, the household is about 150 liters, the temperature is controlled at 55 degrees, the compressor will automatically stop working if it is higher than 55 degrees, and the compressor will start working below 49 degrees, but this is much better than the electric water heater, after all, it is separated from water and electricity, and the safety performance is good. They also heat up differently.

However, I don't agree with buying solar. Because, on a hot day, you hardly need to boil water to take a bath, and when you want to use it on a cold day, the sun is often not very big, and most importantly, the installed water tower is often on the roof, if you want to use hot water, it often takes a long time to put the water before there is hot water. A lot of water is wasted in vain.

Although there are now 2 uses, solar energy plus electric heating. But this ** is a lot more expensive. You might as well buy air energy.

No, specialty stores are available all year round!

Hello dear. There are three solutions, but all of them have certain defects: 1. Time control

The timing control is to start the return pump at the set return time. 1. Regardless of whether the user uses hot water or not, the return pump will be started, which will consume the heat of the hot water, improve the energy consumption of the water heater, and shorten the service life of the return pump. 2. In the set water return time, it will cause the water heater to heat up slowly or not to heat up and other failures.

3. When hot water needs to be used outside the set return time, the return water system fails. 2. Remote control: Remote control is to use the remote control to tell the return pump a start signal when using hot water.

1. There are many hot water intake points for users, and there is only one remote control Zhiliang banquet device, which is easy to lose or difficult to find, and it is extremely inconvenient to use. 2. The key call remote control signal is easy to interfere. 3. Temperature control:

Temperature control is to set a return water temperature, and when the water temperature in the hot water pipe is lower than the set temperature of the return water, the return water pump will be activated. 1. Regardless of whether the user uses hot water or not, the return pump will start every dozen or so to lose the heat of the hot water and increase the energy consumption of the water heater. 2. When the water temperature of the water heater is lower than the set temperature of the return water or the water heater is turned off, the return water pump.

1. Whether the air energy water heater has hot water all day depends on 2 points:

1) Is there a full boot, if the machine is turned on all day, it will definitely be able to produce hot water all day, and the temperature is in a constant state, as long as you boil water and bathe, there will be hot water.

2) The insulation of the air energy water heater water tank, some users are not used to turning on the water heater all day, and it depends on what insulation material the water tank is used, if you want the water tank of Huatiancheng air energy water heater to use a 50mm thick polyurethane foam layer, you can ensure hot water all day**.

Second, whether you need to run the power all day, mainly depends on your needs, if your water consumption is very large, it is recommended to turn on the machine all day, but if it is a general family, turn on the machine before bathing, and turn it off after bathing.

3. Whether there is air conditioning all day, this depends on whether the air energy water heater has this function, if so, it will generally be there when it is turned on and running.

Fourth, the state of air energy water heater is not equal to the unit has been working, and the reason for keeping the water on at any time is that the water temperature in the water tank can be kept between 45-55 degrees Celsius to ensure 24-hour hot water. As long as the unit is not working, there is no need to consume electricity, only when the unit is running, the air energy water heater consumes electricity, but his power consumption is only about a quarter of the electric water heater. On the one hand, the starting point of water in winter is low, and the temperature needs to rise, for example, the water temperature needs to be increased by 55 degrees to heat the water to 70 degrees in the east day, and the water temperature needs to be increased by 30 degrees to heat the water temperature to 70 degrees in summer.

On the one hand, the ambient temperature in winter is low, and more heat is lost in the process of raising the temperature, and the ambient temperature is high in summer, and less heat is lost in the process of raising the temperature.

The air energy water heater heats up to the heating temperature you set and then stops heating, enters the state of insulation, if the insulation is done well, the water temperature drops very slowly, like the beauty of the general day is down 3-5 degrees, if there is no hot water used up, it is considered that there is hot water used every day, if you use more hot water, the cold water will go in quickly, and the hot water in the tank will drop fast, in this case, if you want to save and use the hot water, you need to let the machine continue to heat when you use it, If there are elderly people and children at home, it is recommended to turn on electricity 24 hours a day, let the water heater automatically heat after the water temperature drops, if there are people at home after work, it is recommended to start heating between 3 pm and 4 pm, and when you go home, the water has reached the temperature you set, this heating method allows you to use hot water at any time, and do not waste electricity. If you want to do it, there is still hot water to use.

Air energy water heater, I myself am engaged in machinery, so I know its working principle: air energy water heater can be divided into two steps from the heating process:

One is heating, the air is compressed in the compressor and will release heat;

The second is conduction, the compressed hot air circulates in the pipe hovering in the water storage tank, and exchanges heat with the water in the tank to achieve the purpose of heating the water. Therefore, strictly speaking, it is not simply the use of air for heating, but the conversion of electrical energy to mechanical energy and then to thermal energy realized by the air compressor and air under the action of the power supply. Air has heat, but it cannot be said to be heated by air.

Therefore, strictly speaking, it is not simply the use of air for heating, but the conversion of electrical energy to mechanical energy and then to thermal energy realized by the air compressor and air under the action of the power supply. Air has heat, but it cannot be said to be heated by air.

If the air energy water heater is not used for a long time, it is best to drain the water.

The steps to empty the tank are as follows:

1. There is an overpressure protection device or water discharge valve under the electric water heater;

2. Close the water inlet valve, open the protection valve (water discharge valve), and open the water outlet (hot water faucet, nozzle, etc.) at the same time, and the water can be released.

Precautions: When emptying the water in the water tank, remember to close the protection valve and the water outlet in time to prevent water leakage when the water is loaded next time.

If you don't use it during the day, it's not necessary, mine is open 24 hours a day. Use hot water if you want. Air energy water heaters are very energy efficient. Can't use much electricity in 1 day? There is no need to turn 1 on and 1 off. It's definitely not good for the machine.

The system sets a termination temperature, such as 45 or 50, and the air can be heated to this temperature and then stop running, and the water temperature will automatically heat up when it is lower than this temperature.

You can't turn it off in winter, don't freeze it.

It's okay if it's not frozen, but if it's a snowy area, use an electric water heater! After all, the installed cost of air energy water heaters is not low.

Air energy water heater is through.

By absorbing the heat in the air to achieve the purpose of heating water, no need for light, the annual operating cost is more economical than solar energy, the water and electricity are completely separated, and there is no potential safety hazard of gas leakage and poisoning, which is a reassuring hot water product.

Air energy water heaters are used around the clock all year round and are not affected by bad weather such as cloudy, rainy, snowy and winter nights. The water output is large, and the multi-point water supply is realized, the temperature is set freely, the intelligent defrosting is intelligent, and the whole process is intelligently controlled, which fully meets the various domestic hot water needs of users.

In winter, with the nine constant air energy water heaters, there is no longer the trouble of hot water being hot and cold, and there is no longer the complaint that cold water is heating slowly and the temperature is not high, bringing you convenient, constant temperature and stable hot water enjoyment.

1. Power saving, because the thermal efficiency of the air energy water heater is 300%-500%, which is 4-5 times higher than that of the general water heater, so the cost of making hot water is very low, and it also saves electricity. The daily electricity cost of air energy water heater is 1-2 yuan, which can save about 70-80% of the electricity cost per month compared with general water heaters.

2. Convenient and comfortable, regardless of rain or snow throughout the year, it can provide hot water continuously and automatically throughout the day, which is more convenient than the general solar water heater.

3. Efficient dehumidification, 24 dehumidification capacity of 6-8 kg per day, the effect of plum rain and rainy weather is more obvious, especially suitable for humid southern weather.

4. Low noise, the air energy water heater uses a closed silent compressor, and adopts sound absorption treatment inside, so the noise is very small.

5. It is easy to be affected by the surrounding air environment, and when the weather is cold and the ambient temperature is low, the amount of hot water produced will be slightly reduced. It is easy to frost at -10, and below -20, the unit will stop working. The problem of defrosting is a difficult point to be solved urgently.

6. The air energy water heater is relatively large in appearance, and it is required to be installed on the ground or roof, which has relatively high requirements for the home environment.

7. The compressor is easy to burn out, and the air energy water heater on the market generally adopts a circulating heating system, which is easy to make the compressor aging and carbonization when running under high temperature and high pressure, and if the system lubrication effect is not good, it is easy to cause the compressor to be burned out.

8. The heat exchanger and casing heat exchanger are easy to scale and break, because the outlet temperature of the air energy water heater can reach 50-60, and the water is easy to scale in this temperature range.

Air energy water heater, frequent shutdown and restart, affect the life, frequent switching is not a good thing for any electrical appliances;

The switch of air energy water heater should be divided into the following two situations:

1. If you often use hot water, it is okay to leave it on all the time;

Because, it has been on, than to use it to open it again, because it has been on, it will automatically keep warm at a certain temperature, and then the temperature will drop a little and it will automatically burn it again, that is, it will cost a small amount of electricity to burn again, and when it is burned, it is to burn from low temperature to high temperature, which is always in the use of electricity.

2. If you don't use it for a long time, it's best to turn it off;

Because, if it is not used for a long time, repeated heating will increase the scale and reduce the service life of the water heater.

Because of its energy-saving and environmental protection characteristics, air energy water heaters are more and more used in people's lives, which has brought a lot of convenience to our water heater life. Of course, there are some shortcomings in air energy water heaters, and below, I will analyze the advantages and disadvantages of air energy water heaters.

What are the advantages of air energy water heaters.

What are the advantages of air energy water heaters: environmental protection.

Traditional electric water heaters and gas water heaters are obtained by consuming electricity or gas, gas water heaters will emit toxic gases such as carbon monoxide when they are running, and most of the electric energy of electric water heaters is also obtained by burning coal, so the environmental performance of the two is poor. Air energy water heater is to transport the heat in the air to the water through the refrigerant, air is an inexhaustible energy, only need to consume a small amount of electricity during operation, and the environmental performance is excellent.

What are the advantages of air energy water heaters: energy saving.

The biggest advantage of air energy water heater is energy saving, heat exchange efficiency is as high as 350%-500%, low cost of use, heating the same amount of hot water, the cost of air energy water heater is only 1 4 of electric water heaters, 1 3 of gas water heaters, and 1 2 of solar water heaters.

What are the advantages of air energy water heaters: large water output.

The water tank capacity of the air energy water heater is between 150L-760L, and the user can choose the corresponding capacity of the air energy water heater according to the needs of the family, with a large water output, which can continuously meet the hot water needs of multiple water points of the family at one time, including kitchen hot water, bathing water, etc., which truly realizes the best hot water for the whole family and improves the quality of life of users.

What are the disadvantages of air energy water heaters.

What are the disadvantages of air energy water heaters: large size.

Due to the large capacity of the air energy water heater tank, it is relatively large in size, occupies a large space, and has specific requirements for the installation environment, resulting in some families being unable to install.

What are the disadvantages of air energy water heaters: frost problem.

The heating efficiency of the air energy water heater is directly related to the temperature of the air source, which is easily affected by the surrounding air environment, and the regional characteristics are obvious. Therefore, it is recommended that users in the north install air energy water heaters indoors.

In fact, there are many acquaintances between air energy water heaters and air conditioners about power consumption, the main engine needs to use compressors and evaporator parts, etc., air conditioners use evaporative cooling, heat pump water heaters use condensation heat, condensation heat is evaporative cooling plus compressor power consumption, so compared with air energy water heaters, air conditioners consume more electricity, and because the space for air conditioning refrigeration is relatively large, the power is larger than that of air energy water heaters, air conditioners have no insulation function, and the cold air made is easy to lose, and they need to be kept running to ensure the refrigeration effect of air conditionersThis leads to a long running time of air conditioners whether it is refrigeration or heating, so compared to air energy water heaters, it is more energy-efficient
