Which auxiliary heating is best for solar hot water projects?

With the social development, the continuous improvement of living standards, people have higher requirements on the quality of life, and the hot water is an indispensable part of people's health of life, but the contradictions between people and consume a lot of energy demand for hot water, and the birth of a solar hot water project to solve this contradiction, investment solar hot water project is relatively low cost, will not cause pollution to the environment, is the best choice for people to use energy. But as you all know, solar water heating project is very convenient, but in light of insufficient circumstances, there will be some trouble, all need to start auxiliary heating, otherwise the water is not hot enough! Which kind of auxiliary heating is the best then?
At present, solar hot water project has several ways, such as electric heating auxiliary heating, boiler steam auxiliary heating, auxiliary heating of gas stove and auxiliary heating of air energy heat pump.
Electric heating assisted heating
Mainly through the electric heating of water, so that heating way although fast, there are two bad, the first, the water and electricity have not been separated, the second instant heating, the consumption of electricity is very large! From the point of view of safety and energy saving, it is not advocated!
Boiler steam assisted heating
The boiler is a kind of energy conversion equipment. The energy input to the boiler is the chemical energy and the electric energy in the fuel. The boiler outputs steam, high temperature water or organic heat carrier with certain heat energy. This way of heating is too expensive, and the combustion is not sufficient, the pollution of the atmosphere is also very serious, the safety factor is not high, although the boiler auxiliary heating seems to save money, it actually consumes a lot of manpower and resources!
Auxiliary heating of gas stove
The auxiliary heating needs to start the high water pressure, live in high-rise users, such as the installation of booster pump will not be able to start the installation; to a hole in the wall exhaust fan; different gas burner nozzle, its shape, size, gas channel cross-sectional area are not the same!
Auxiliary heating of air energy heat pump
The heating of the solar hot water project is the best auxiliary heating, with the use of low cost, easy operation, good heating effect, safe, clean and multiple advantages, it uses a small amount of electricity from the air temperature in the compression temperature on water is heated in such a way, safety and energy saving. A large number of pollutants can also gradually reduce the traditional heating brings to the atmospheric environment, the year basically is available!
