Is an air energy water heater suitable for household use? Is it energy efficient?

First understand what air energy is, air energy is to absorb low-temperature heat in the environment through refrigerant, and convert it into high-temperature heat through compression, and then use heat exchange to heat the cold water in the tank.

Of course, air energy is suitable for household use, and the installation is the same as the air conditioner, which is to add a hot water storage tank, which can refer to the air energy water heater of Muge in Four Seasons, and the water tank is quite beautiful.

When it comes to energy saving, the electricity of air energy is mainly consumed in the internal compressor work, most of the heat required to heat the water mainly comes from the low temperature heat in the air, the efficiency is the highest when the ambient temperature is 20, the compressor consumes 1 degree of electricity, which can produce a heating effect of 4 degrees of electricity, which is quite energy-saving.

Of course, the lower the ambient temperature, the lower the efficiency of the unit. The ambient temperature of the household air energy water heater unit is generally -7 43. At -7, the efficiency of the unit is reduced to a minimum, coupled with the defrosting consumption of the unit, and it will not save energy if it is continued to be used.

The air source water heater is a new type of energy-saving and efficient water heater. Compared with the traditional electric water heater, the energy efficiency ratio is above, that is to say, 1 kilowatt of electricity can produce more than 10 million heat, while the traditional electric water heater only has an energy efficiency ratio, that is to say, 1 kilowatt of electricity only produces kilowatts of heat. It can be seen that the energy-saving effect of air source water heater has been achieved.

Compared with solar water heaters, the biggest feature of air source water heaters is that they can produce hot water 24 hours a day. When it rains or snows on a cloudy day, or when there is no sun at night, the solar water heater can only be heated by electricity, and it becomes a traditional electric water heater. Its total annual electricity consumption is not much less than that of an air source water heater.

Of course, the disadvantage of air source water heater is that it is high, and the quality of domestic brands is poor, which affects the promotion of air source water heaters. It is recommended to choose an imported or joint venture brand. Such as the American brand PHNIX

Air energy water heaters.

The most fundamental principle is also to use electrical energy to convert into heat energy, of course, it is also a water storage type, the volume will be larger, and the installation environment requirements are high.

Gas water heaters.

The use of gas to heat water can provide a constant temperature and pressure of water, provided that gas is available.

From the perspective of physical feeling, the gas water heater will not have no hot water in the bath, and the water storage of the air energy water heater is preferred.

From the perspective of energy conservation and environmental protection, air energy water heaters are more environmentally friendly and more energy-saving.

I have always suggested in line with one strategy: with a budget of less than 3000, a gas water heater is recommended.

Budget more than 3000, direct air energy. Air energy is better than gas water heaters in terms of comfort, energy saving, safety and environmental protection. Why do you say 3000 as the limit?

Because the two are compared by comparison, because the air can be energy efficient even in winter.

At its lowest, the cost is still 32% of that of a gas water heater. In the other three seasons, the air energy cop can reach more than 4, and of course, the initial temperature of gas heating will also be above 20, compared to the air energy water heater.

The cost remains at about 30% of that of a gas water heater.

However, the mainstream brand of gas water heater is below 3,000 yuan, and the mainstream air energy is basically above 5,000 yuan, which means that the energy cost saved can be leveled for at least 4 years, and the advantage is not big. However, from the perspective of life, the shelf life of air energy water heaters.

For more than 6 years, the warranty of Haier can reach 10 years. In this way, from a long-term perspective, combined with the unique safety and constant temperature characteristics of air energy, the advantages of air energy far outweigh the disadvantages. For details, please refer to the following article:

The summer breeze is like a song, the summer breeze is like a song: how to buy an air energy water heater: the key points to grasp.

Answer: The electricity consumption of the gas water heater itself is very small, so there is no way to compare the two products of air energy water heater and gas water heater simply by the size of the electricity consumption. And this comparison is not very meaningful.

Air energy water heaters also consume electricity to work. Compared with electric water heaters, it can save about 40 70% of electricity.

In the process of heating water, the air energy water heater will absorb more heat from the outdoor ambient air and transfer it to the water while consuming a certain amount of electricity. In the case of 20 degrees in the outdoor environment, every 1 kilowatt-hour of electricity consumed can transfer the heat equivalent to 3 kilowatt-hours of electricity to the water; When the outdoor ambient temperature is about 7 degrees, every 1 kilowatt-hour of electricity consumed can transfer the heat equivalent to 2 kilowatt-hours of electricity to the water; When the ambient temperature is below 0 degrees Celsius, the heat equivalent to the kilowatt-hour of electricity can be transferred to water for every 1 kilowatt-hour of electricity consumed. Compared with electric water heaters, it is much better to consume 1 kWh of electricity to produce heat equivalent to 1 kWh.

However, air energy water heaters also have a lot of disadvantages:

Disadvantage 1: Relying on the refrigeration system to achieve hot water production in reverse Carnot cycle, the system is complex and prone to failure;

Disadvantage 2: The hot water production capacity is greatly affected by the outdoor ambient temperature, the higher the ambient temperature, the better the effect, and the lower the ambient temperature, the worse the effect; It cannot be used when the ambient temperature is lower than -10 degrees;

Disadvantage 3: The final water temperature heated by the heat pump alone generally does not exceed 60 degrees, if a higher water temperature is required, only the auxiliary electric heater is equipped to continue heating;

Cons 4: **High.

Water heater is our most commonly used household appliances, its emergence has greatly facilitated our life, such as winter, summer or other two seasons can ensure that we take a hot bath, now more popular is the air energy water heater. And the air energy water heater not only has the ordinary solar heat function, but also it has very good intelligent characteristics, the air energy water heater mainly uses air energy, it not only has very good environmental performance when heating, but also the heating speed is very fast. So let's talk about air energy water heaters.

Is the air energy water heater any good

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

2.Convenient and comfortable, regardless of rain or snow all year round, hot water can be continuously and automatically provided 24 hours a day, which is more convenient than ordinary solar water heaters. Efficient dehumidification, the maximum dehumidification capacity of 24 hours a day is 6-8 kg, and the effect of rainy season and rainy weather is more obvious, especially suitable for humid southern weather.

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

3.Environmental protection, because the household air energy water heater does not use gas, so it will not produce exhaust gas, so that it will not damage the ozone layer, but also because it saves electricity, and every time the consumption of electricity is reduced, it can reduce the pound of carbon dioxide production when generating electricity, and it can also reduce the destruction of the ozone layer. Therefore, the use of household air energy water heaters can also delay the "global warming".

It can also be used to purify indoor air for town tombs.

4.Safety, household air energy water heaters do not use gas, so the potential safety hazards of carbon monoxide poisoning can be completely ruled out. It will also not be heated with an electric heating rod to rule out the possibility of leakage. So it's safer for the Wangs.

5.It can be used by many people, the temperature control of the household air energy water heater will automatically stop when the temperature control reaches 55, when the hot water is started, there will be cold water in, until the temperature drops to a certain temperature, the system will automatically start, and can continuously produce 45-55 hot water 100-700 liters per hour. After testing, the shower water temperature per person needs 42, 40-50 liters of hot water, and the household air energy water heater can provide more than 3 people with a continuous shower.

The above is what you have told about air energy water heaters, I think you should have a very good understanding of air energy water heaters after reading them. Air energy water heater is a very advanced type of water heater. Therefore, many friends have installed air energy water heaters at home.

With the development of science and technology, many new water heaters have emerged more and more rapidly, such as solar thermal water heaters, gas water heaters, and electric water heaters. But now the air energy water heater is a kind that everyone likes very much, it has a lot of functions, and it is also very intelligent.

You can get it for free

At present, there are two kinds of technologies that claim "air energy" in society: one is pseudo-science to deceive people, and the other is real science, which can save energy.

The former actually uses compressed air to do the work.

Originally, this was just a form of energy storage, because it needed to consume energy to compress the air, and then the output of work could actually be less than what was previously consumed. But propagandists lie that they can output more work "from the air" (so they call themselves "air energy"). This kind of propaganda is a kind of "perpetual motion machine"**, similar to the previous "water to oil"**.

The latter (the so-called air energy heat) is not used to do work, but only to provide heat.

It uses the principle of a heat pump to extract part of the heat from the ambient air while consuming energy (electricity consumption), and transmits it to the user who needs heat together with the heat it consumes. Compared with the old simple "burning electricity to generate heat", this technology greatly reduces the waste of energy and has the significance of energy saving.

Although the latter is a real technology, there are also flaws in the publicity, that is, the wording "air energy" is easy to misunderstand, and it is used by the former as a "evidence" for them to promote pseudoscience.
