For domestic water heaters, everyone wants to choose a water heater that is safe, durable, easy to use, and saves money.
Among them, storage electric water heaters, gas water heaters, and solar water heaters are the mainstream water heaters.
However, some of the new types of water heaters were really popular for some time.
The air energy water heater is a very typical water heater, which is energy-saving, safe and easy to use.
Nowadays, however, they are rarely used. Do you know why?
What is an air energy water heater?
Since we want to understand why fewer and fewer people use air energy water heaters, we must first figure out what an air energy water heater is.
Air energy water heater, in essence, is also a kind of water heater, which can use air as an energy source to a certain extent, which is the name of the water.
For air energy water heaters, the more accurate introduction is as follows:
Air energy water heaters, also known as "air source heat pump water heaters". The "air energy water heater" absorbs the low-temperature heat in the air, vaporizes the fluorine medium, and then pressurizes and heats up through the compressor compression, and then converts the water to heat through the heat exchanger, and the compressed high-temperature heat energy is used to heat the water temperature.
Why do so many people want to install air energy water heaters in the first place?
In fact, the reason why many families choose air energy water heaters at the beginning is mainly due to the advantages.
Because, compared with the traditional water heater, the air energy water heater first realizes the separation of water and electricity in a complete senseSecondly, it has a better energy-saving effect.
As for the reasons why it can be accepted by many people, I will summarize it personally, mainly the following six points:
High efficiency. Air energy water heaters are highly efficient and energy-saving. With the same amount of hot water, the efficiency of an air energy water heater is 4-6 times that of a general electric water heater. Its average annual heat efficiency ratio is 4 times that of electric heating, and the utilization energy efficiency is high.
Easy to install and less restricted. The air energy water heater overcomes the shortcomings of solar water heater that relies on sunlight for heat and is inconvenient to install.
Separation of water and electricity is safer. Since the work of the air energy water heater is through the medium heat exchange, it does not require the electric heating element to be in direct contact with the water, which realizes the separation of water and electricity in a complete sense, and avoids the danger of leakage of the electric water heater.
Keep away from the area of use, there will be no ** and gas poisoning. It prevents the risk of gas water heater poisoning, and more effectively controls the exhaust gas discharged by the gas water heater to avoid air pollution.
The conditions of use are more relaxed. Air energy water heaters don't need sunlight, so they can be placed at home or outdoors. The conditions of use are also simpler.
More comfort. Once the stored water in a solar water heater runs out, it is difficult to produce hot water immediately. If it is heated by electricity, it will take a long time. The air energy water heater, above minus 20 degrees Celsius, can operate under pressure 24 hours a day.
Why do so few people use air energy water heaters anymore?
Since air energy water heaters have so many advantages, why are few people using air energy water heaters now?
In fact, for this point, you will also find that when most homes are renovated, they basically consider storage electric water heaters and gas water heaters.
For the purchase of air energy water heaters, it is indeed becoming less and less.
It can also be seen that air energy water heaters cannot meet the needs of families in many aspects.
In particular, the following points are more prominent, so that many friends have to give up air energy water heaters.
(1) - High installation space requirements
A very important reason why many friends can't choose air energy water heaters is that the requirements for installation space are relatively high.
For air energy water heaters, in fact, we can simply understand them as outdoor units of air conditioners, plus storage electric water heaters.
This means that if we want to install an air energy water heater, then we have to have a water heater host and a water tank in our home that can install air conditioning.
The main engine and water tank of the air energy water heater are equivalent to an outdoor unit of the air conditioner, and it is equivalent to a storage water heater.
So for this, there are many families that are difficult to satisfy:
For those who live in buildings, most of them do not have the space to install air energy water heaters. Because in the space, it's basically an air conditioning unit, but it can't put a water tank. Therefore, the installation position is limited.
If you install it on a balcony, you will find that almost half of the balcony is occupied by an air energy water heater. Not only is it not good-looking, but it will also bring a lot of difficulties to the decoration of the balcony.
Therefore, to install an air energy water heater, we must consider whether it can be installed or not. This problem also restricts many families.
(2) - High
One of the very important reasons why air energy water heaters have been abandoned by many friends is that they are relatively high.
I believe that when you buy different water heaters, you will compare them and want to choose a lower water heater.
And if the ** of a water heater is very high, I believe many friends will give up.
When we compare air energy water heaters, gas water heaters and storage electric water heaters, we will find that the price difference between them is indeed very large.
Among them, the air energy water heater can be said to be the highest among all these water heaters:
The most common example is a 200-liter air energy water heater. A common domestic brand of 200 liters of air energy water heater basically costs seven or eight thousand yuan or even tens of thousands of yuan.
If we choose an 80-liter storage electric water heater or a 20-liter household gas water heater commonly used in the family, we will find that basically two or three thousand yuan or three or four thousand yuan is completely enough.
It can be seen from this that an air energy water heater is five or six thousand yuan more expensive than an electric water heater. Many people consider this price difference and often give up air energy water heaters.
(3) - Greatly affected by the outdoor environment
Air energy water heaters have a very big drawback, that is, they are very affected by the outdoor environment.
Because, the reason why an air energy water heater is called air energy is that it needs to use the waste heat in the air.
To put it bluntly, the higher the temperature of the outdoor air, the better the effect of the air energy water heater.
However, the outdoor ambient temperature changes gradually throughout the year, so in this process, the impact on air energy is very large.
In particular, in some special areas, air energy may not be available in winter.
For example, air energy water heaters may have the following situations in use:
It cannot be operated at low temperatures. For example, in the winter in Northeast China, it may reach minus twenty or thirty, and it is difficult to produce hot water from air water heaters. Even when hot water is produced, it is inefficient.
Electric-assisted heating is more power-intensive. Especially when the outdoor temperature drops, it is difficult for most air energy water heaters to use the air waste heat, and the water heater will use electricity to supplement the heat. To put it bluntly, it is to use electric heating, which is very expensive at this time.
Thermal efficiency decreases quickly. For example, the new air energy water heater feels very easy to use and saves electricity in the first year. However, after two or three years, you will find that the air energy water heater is very power-intensive, which is the efficiency decreases.
All in all, air energy water heaters will be less efficient with the increase of service life, and they are very affected by the outdoor environment. When it comes to use, there are great limitations.
(4) - maintenance troubles
Compared with traditional electric water heaters or gas water heaters, air energy water heaters also have a very prominent problem, that is, maintenance is more troublesome.
For most households, the water heaters we have installed in our homes are almost always usable, maintenance-free, and rarely malfunction.
However, air energy water heaters are different.
Because air energy water heaters do work differently from other water heaters.
Therefore, there may be some problems in the process of using air energy water heaters.
And for these problems, it is difficult for us to solve them ourselves, and we need to find after-sales service to deal with them
Frost. The problem of frosting is a very common problem in the use of air energy water heaters. Especially in winter, when the outdoor temperature is extremely low, the impact will be very large, and it may even be impossible to use it without hot water.
Scaling. The second problem of air energy water heater is its fouling. Because the air energy water heater increases with the increase of service life, its scaling is still very bad. If it is not effective in descaling, the efficiency will decrease year by year, and eventually it will not be usable.
Therefore, compared with the traditional water heater, the air energy water heater is still more troublesome in the use angle, and it is not as worry-free as the traditional water heater.
(5) - The compressor is easy to burn out
For air energy water heaters, the core component is actually the compressor.
However, for the compressor of the air energy water heater, there is a very fatal flaw, that is, it is easy to burn out.
Because the current common air energy water heater is basically a heat pump water heater, which adopts circulating heating.
In the process of working with circulating heating, it may bring the following problems:
There is a defect in the circulating heating system, that is, under high temperature and high pressure conditions, when running, it is easy to make the compressor age, carbonize, and the lubrication effect is not good.
The combination of the above problems will gradually eventually lead to a defect, that is, the damage of the compressor.
Therefore, everyone will also worry about the service life and failure of air energy water heaters, and slowly stop buying air energy water heaters.
Written at the end of the article
Air energy water heater, conceptually speaking, is a very energy-saving, safe and environmentally friendly water heater. However, there are many limitations to use and installation.
Therefore, as for whether to choose an air energy water heater, we must first confirm whether we are familiar with the air energy water heater, and then confirm whether the area where our home is located is suitable. Figure these out before deciding whether to buy or not.
