In the domestic heating market and the hot water market, there are some similar places. Solar water heaters and air source heat pump water heaters have been competing for the dominant position of the market. After summing up years of experience, the main questions of customers are as follows:

1. If the air energy heat pump and the solar heating hot water are done together?

2. What are the advantages and disadvantages of air energy heat pump hot water heating and solar water heating?

3. If solar energy is used as an aid, how much is the contribution of solar energy? Is there any value in investing in solar energy?

First of all, for commercial hot water heating projects, if you use clean energy, you must use heat pump for the main reason. The reason is very simple. The sun only has daytime, there is no sun for more than ten hours at night, and it encounters rainy days and fog. Haotian Solar has no way to use it. It can only be heated by electricity. The energy consumption is high, so you can imagine it. Air energy heat pump hot water heating is relatively easy, although it also faces the problem of ring temperature drop attenuation, but at least 24 hours of energy-saving and environmentally friendly cleaning units. For this reason, the leading heating unit must be an air energy heat pump.

The second question, what are the advantages and disadvantages of air energy heat pump hot water heating and solar water heating?

Solar water heaters can't collect sunlight heating at night. If the hot water heated during the day is used up, and the water needs to be used temporarily, the electric heating function must be used. The air can be slightly better than the degree of freedom and heating speed.

To the last question, taking Hebei as an example, according to the annual sunshine time of about 2000 hours, according to the temperature rise of 30 °C, it can produce 12 tons of domestic hot water, about 77,000 yuan (excluding insulation tank). For the 10 ton hot water project, on the basis of the heat pump, another 77,000 yuan will be invested, and the gains obtained are few. It is self-evident. In most areas, if the air source heat pump has been used for commercial hot water, then solar energy is used. It is not necessary, mainly because the investment efficiency is too low, not to mention a series of problems caused by the complicated system and high maintenance cost caused by adding more solar systems.

In view of the above reasons, in the hot water and heating market in recent years, the development of air-energy heat pumps is better than solar energy. Although solar energy is supported by factors such as state subsidies, it is destined to be unable to be used as the main heating equipment because of its own determination. used widely.
