Not included. Common water heaters include electric, solar, and gas. Gas mainly includes natural gas and liquefied petroleum gas. However, the problem of solar water heaters and gas water heaters can also be installed. added when installing a gas water heater, in many households solar water heaters and gas water heaters are shared.
If it is convenient to install solar energy, of course it is more suitable to install solar energy.
With a one-time investment, the cost of future use will be very low. Even in rainy weather, you can use the electric backup heater to heat the water for use. solar water heater, you must also install a water temperature and level indicator. This way you can easily check the water temperature and water level in the solar water tank. In winter or rainy weather, vYou can add half or three cells of water. , so that the heating time is very fast and it is very convenient to take a bath or use hot water. However, if the user is in the northern region, the pipes should be well insulated during installation and good quality thickened insulation jackets should be installed. Otherwise, when the temperature is very low in winter, the water pipes will freeze and become unusable.
Detailed information:
Solar water heater:
With the improvement of technology level, solar water heaters have generally become evacuated collector tube solar water heaters. The water in the vacuum tube uses the principle that hot water floats and cold water sinks. After absorbing solar thermal energy, it circulates through temperature differences to heat water in thee water storage tank.
1. Advantages:
The advantages of solar energy are safety, energy saving, environmental protection and economy. Especially solar water heaters with auxiliary electric heating function, which is an energy utilization method based on solar energy and supplemented by electric energy, so that the solar water heater can be used all year.
2. Disadvantages:
Its disadvantage is that the installation is relatively complicated. If it is not installed correctly, it will not only affect the appearance and quality of the house but also. This affects the appearance of the city and its maintenance. This is more inconvenient because the solar water heater is installed outdoors, mainly on the roof of a building, so it needs to be cleaned and maintained outdoors.
However, high-rise residences cannot use energysolar. For low-rise residences, losses relating to the 1st to 3rd floors are relatively significant.
Solar water heaters also have water pressure issues. If the water tank is lower than the solar water heater, i.e. the water pressure is very low, it will not be able to supply water. is not enough, a booster pump will be installed to solve the problem!
Although the water in the solar water heater tank will not freeze, the inlet and outlet pipes may freeze, insulation measures must therefore be taken. ! As for times when there is no sunshine in winter, electric heating pipes should be used for heating.
