Solar energy and natural gas are used together. If the solar water is not full, it will not affect the natural gas.
Installing a gas water heater has nothing to do with cold water pipes. You can either share a cold water line with a solar water heater or install a separate cold water line.
The key is that you need to add a transfer switch at the connection between the hot water supply pipes from the solar water heater and the gas water heater. When using the solar water heater, open the solar water heater. valve of the hot water pipe and close the valve of the gas water heater;

When using a gas water heater, close the valve of the hot water pipe hot water supply to the solar water heater and open the valve of the gas water heater. .
The prerequisite for starting the gas water heater is the power of the water flow when thehot water tap is open. If the hot water tap supplying the shower is turned off, the gas water heater will not start without the power of the water flow, so there is no impact.
Why can gas water heaters be installed on the first and second floors to use solar energy but not gas water heaters?
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, you can add half or three cells of water. , sote 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.

Solar water heater:
With the improvement of technology, solar water heaters have generally become solar water heaters. vacuum collecting tubes. 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 st tankwater storage.
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 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 solar energy. For thelow-rise residences, the relative losses between the first and third floors are 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 times when there is no sunshine in winter, electric heating pipes should be used for heating.

Should I install a gas water heater if I already have a heater solar water?
The source of energyThe auxiliary element of current solar water heaters is generally electricity. Due to the structure of solar water heaters, they cannot be used with gas. When comparing solar water heaters to gas water heaters, the results are as follows:
Friends who have used solar water heaters don't need to tell you about the benefits solar water heaters: environmental protection and energy saving, no need to pay electricity or gas bills, hot water is available when the sun is available and hot water is available when there's no sun. Electric heating is also available. Overall, this saved a lot of money. Solar water heaters also have many limitations that must be considered before installation.
Gas water heaters are the most dangerous and expensive water heaters to operate. Water heatersu solar generally have electric auxiliary heating. When there is no sun, it is a good electric water heater in itself. Why install a gas water heater? Even if you have a large family and are worried about the lack of hot water from the solar water heater, do not install a gas water heater. Simply install a tankless water heater. It is best to use it in series with the solar water heater. the water temperature of the solar water heater is sufficient, turn off the electric water heater; When the water temperature of the solar water heater is not enough, turn on the instant electric water heater to warm it up. This method is good, but the pipeline is a bit complicated and not all installers may know it.
