Which is better, air-energy or gas water heater?

Air-energy water heater (hereinafter referred to as air-energy) has an external unit like an air conditioner, and then there will be a heat storage tank next to it; but the home rarely uses integrated water storage water heaters, and the most commonly used is the wall-mounted water heater.

1. Comparison of purchase price

There is no doubt that the price of air water heaters is much higher than that of wall-mounted water heaters. If some large families use water storage water heaters, their purchase price is higher than that of air water heaters. If it is an ordinary household user, gas water heaters will be given priority for price considerations.

2. Comparison of occupied space

Due to the product structure of the air-energy water heater, the external unit can be hung on the wall, but there are requirements. The specific requirements are similar to the installation of the air conditioner external unit, and can refer to the air conditioner installation requirements; in addition, it also has a heat storage tank, which usually requires 1㎡ of space; gas water heaters can be installed on the wall and will not take up too much ground space.
The installation of air energy, the distance between the outdoor unit and the heat storage tank is to hope that the effect is as short as possible, so many factors should be considered during installation, such as outdoor unit heat dissipation, power supply, water source, drainage and other issues; installing a gas water heater is much simpler, and only water and electricity need to be met.
Therefore, in ordinary apartments, using a gas water heater is a better choice.

3. Convenient to use, better timeliness of hot water

The consideration of this factor is of more concern to everyone. First of all, from the convenience of use, they are very convenient equipment, but the air can look a bit complicated because it has a pump and other accessories, but also waits for hot water to arrive, and directly opens the faucet to use.

In addition, it is obvious that the gas water heater's ability to reheat hot water is much higher than that of air energy, and its thermal efficiency can produce hot water in time. The heat exchange capacity of air energy cannot achieve the effect of gas, and must wait for the regeneration of hot water.

Therefore, in people's lives, users who choose gas water heaters are higher than air energy, because users need to use it simply. Timeliness of hot water.

4. Comparison of installation convenience

The installation of gas water heaters is almost always indoors, and only a few screws are needed to connect the water pipe components after fixing; the installation process of air energy will be much more, and sometimes it is necessary to install and fix it on the outer wall with a safety rope. Therefore, compared with the convenience of installation, the installation of gas water heaters is simpler and the cost is lower.

5. Comparison of later maintenance costs

The stability of gas water heaters is directly affected by air. Water quality. The impact on gas quality should be regularly cleaned. The exhaust channel, water channel, and gas channel. As long as the refrigerant does not leak, air requires almost no maintenance. Therefore, for future maintenance, air can save a lot of trouble.

6. Comparison of energy consumption

Speaking of their specific energy consumption comparison, this is a more complicated topic because it depends on the ambient temperature and usage.
In addition, the lower the outdoor temperature, the slower the hot water capacity, and even the start of electric auxiliary heating to heat hot water, the higher the energy consumption.

The above is a comparison between air energy and gas water heaters. Generally speaking, for ordinary mass users, it is better to use gas water heaters than air energy because it is convenient to have hot water in be timely manner. This depends on the specific area of ​​use. Air-energy water heaters not only have insufficient hot water supply, but also have high energy consumption, which is similar to using gas water heaters.
