Now which kind of water heater is good, solar energy, air energy, and pick the eyes are all spent!

It must be as new as possible, and technology is developing! Cry to death when the sun is gone! I've had my time. I recommend one.

Preferred: The roof has installation conditions, solar: 3 executives, 1800*58, 30 tube series, cost price 2800. No need for electric assistance, no sunshine for a family of 5, can be used for 3 days. If you don't have the installation conditions, don't consider the balcony wall-mounted.

Secondly: there is pipeline gas, and the cost of installing a gas water heater is about 2000. It can be mixed with solar energy conditionally.

Again: none of the above conditions, electric water heater, about 1000 yuan.

Finally, consider air energy: south of the Yangtze River, or further south, can be considered for use, and it is better not to consider it for the north. The cost price is about 4800. Choose 200L or larger volume, the equipment has good stability, can meet the large capacity of water, people do not fire.

If you are using it for commercial purposes, the combination of solar and air energy is the best option.

Each has its own advantages and disadvantages. When the solar sun is good, it is a zero-cost hot water, but the effect is not very good on cloudy days and winters, so it has to be heated with electricity. If it is on the coast, it is necessary to pay attention to the installation firmly, this time the two typhoons came together, and the typhoon passed over, and the solar energy suffered heavy losses.

Electric heaters are cheap, but the operating costs are the highest, and there is also a potential risk of leakage. The air can save electricity, the electricity consumption is only 1 3-1 4 of the electric water heater, the water and electricity are completely isolated, the water tank is not electrified, the safety is good, the water temperature is adjustable, and the comfort is good, but it is high and large. You can pick a suitable type according to your own reality.

As long as you use it, both solar and air energy are good. The cost is about the same for a year, the air can have hot water 24 hours a day, and the solar energy is generally available at night. Energy saving and environmental protection.

It depends on what you use it for, in what area, whether it is for commercial or domestic use, and how many people use it.

Solar water heater is good.

The working principle of air energy water heater is a heat pump, through which the heat energy in the air can be transferred to the water to heat up the water. Its heating coefficient directly depends on the air temperature (air temperature), and the intensity of sunlight is not light. The heating coefficient can reach 7-8 in the hot summer and only 2-3 or even lower in the winter.

Whereas, heat pumps need to consume electricity to work.

Solar water heaters can convert light energy into heat energy, so as long as there is sunlight, hot water can be produced, if the heat collection area is large enough, the water capacity is large enough to use up hot water on the day, and the next day even if there is no sun, there can be hot water. On rainy days, you can also use auxiliary electric heating to save the emergency. Air energy water heaters need to occupy a certain amount of housing space, while solar energy does not take up indoor space.

How to choose a water heater:

1. Look at the inner tank, the inner tank of the electric water heater is divided into stainless steel inner tank, enamel inner tank, and galvanized inner tank, among which the stainless steel inner tank has the best quality and long life, which is slightly higher.

2. The galvanized liner has the shortest life and low cost.

3. Pay attention to safety performance, electric water heater should have anti-dry boiling, anti-over-temperature, anti-overpressure device, leakage protection and automatic disconnection without water, as well as additional power-off indication functions.

4. It is safer to choose products with large thickness of moisturizing layer and high density of insulation materials.

5. The key to the impact of thermal insulation effect on the power consumption of water heater is the thermal insulation effect, and it is more energy-efficient to choose products with large thickness of moisturizing layer and high density of thermal insulation materials.

6. Pay attention to the heating pipe of the electric water heater, the quality of the heating pipe, and the electrical performance of the electric heating pipe directly affect the use of the electric water heater.

Solar water heaters are very common in our lives, it is a tool that can help us provide hot water for bathing, and it is very common in our lives. Nowadays, people are very stressed in their lives, so when they are finished after a day's work, they want to take a shower to help relieve stress. Solar water heaters have helped us achieve this wish.

There are also many different types of solar water heaters. Air energy solar water heaters are one of them. What about air energy water heaters?

How about an air solar water heater

1. Safe and reliable.

Compared with electric water heaters and gas water heaters, air energy water heaters have very good safety performance, especially for families with elderly people and children at home, air energy water heaters can generally operate normally within the temperature difference of -5 degrees to 43 degrees, it is recommended to run in spring, autumn and summer, and use more in East China, South China and other areas south of the Yangtze River. Winter in the north may not be used.

2. Convenient and comfortable.

The air source water heater is regenerative type, and the heating function is automatically started according to the temperature in the water tank to ensure that the hot water is sufficient for 24 hours, so there will be no problem that the gas water heater cannot meet the hot water of multiple faucets at the same time, and there will be no problem that the electric water heater has a small capacity and many people need to wait for a bath. Ready-to-use hot water, large water output, stable water temperature, meet all your hot water expectations.

3. Economy.

The electricity consumption of air energy water heater is far less than that of electric water heater, generally speaking, only a quarter of it is needed, according to the statistics made by the relevant department of Chimen, a normal family of four, a year with air energy water heater than electric water heater to save nearly 1,000 yuan.

4. Green environmental protection.

From the beginning of the design and manufacture of the air energy water heater, environmental protection is the primary consideration, it only transfers the heat in the surrounding air, and does not release harmful gases to attack the body, so it does not have any impact on the environment.

5. Low maintenance rate.

Although the structure of air energy water heaters is complex, they are relatively durable and will not break down often like water heaters.

Compared with other types of solar water heaters, the biggest feature of air solar water heaters is that they are safer. Therefore, air energy water heaters are more suitable for families with elderly people and children at home. The hot water efficiency of the air energy water heater is very high, and it can ensure that the temperature of the water is above 43 degrees.

Hello, glad for your question. Air energy water heater is better than solar energy, because solar water heater is susceptible to weather influences, if there is a cloudy day, the heating speed will be slow, and the volume is large and the range of use is low, while the air energy water heater can absorb and convert heat no matter what the environment, but the compressor requirements are high.
