It is best not to install and use solar and gas water heaters simultaneously. Installing solar and gas water heaters at the same time can easily block pipes and pose safety hazards. It is recommended to simply use a gas water heater. There is no need to affect the use of hot water due to weather conditions, and it is also very quick and convenient.
Solar water heater is a device that converts solar energy into thermal energy, heating water from low temperature to high temperature to meet people's use of hot water in life and production. Solar water heaters are divided into vacuum tube solar water heaters and flat panel solar water heaters based on their structural shapes. Evacuated tube solar water heaters are mainly used, accounting for 95% of the domestic market share. The chaDomestic vacuum tube solar water heaters are composed of heat collecting tubes, water storage tanks, brackets and other related parts. The conversion of solar energy into thermal energy mainly relies on vacuum heat collecting tubes which use the principle of hot water floating. and cold water flows to cause microcirculation in the water.
Gas water heater, also known as gas water heater, refers to a type that uses gas as fuel and transfers heat to cold water circulating through the heat exchanger via combustion heating to achieve the purpose of hot water preparation. . Gas appliances.
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 user the auxiliary electric heater to heat the water to be used. 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, you 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 With the improvement of the technological level, the heaterssolar water heaters have generally become evacuated collector tube solar water heaters. The water in the vacuum tube uses the principle of hot water to float and cold water to sink. After absorbing solar thermal energy, it circulates through temperature differences to heat the water in the 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 thehouse, 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 solar energy, and low-rise residences, 1-3The relative loss of the building is also relatively large.
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 the periods when there is no sun in winter, it isut use electric heating pipes for heating.
