Gas water heaters are the most dangerous and expensive water heaters to operate. Solar water heaters 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.
Should the solar water heater be connected to a water heatergas or electric?
The auxiliary energy of today's solar water heaters is usually electricity due to the structure of solar. water heater, it 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.
Is it better to use a solar water heater or a gas water heater?
This is generally not necessary, but it is doable if you want, but the specific operation is very complicated. And there are many pipelines. There are many valves. You must fully understand its operating principle, and its feasibility must be combined with the real situation of your house (certain shapes of pipes, aesthetics, etc.). Even if you save money, you won't make it. to save so much. You can Under normal circumstances use solar energy. If the weather is bad, you can use gas (occasionally, solar energy has a heat preservation function, unless the pipes freeze in winter, and now solar energy is generally photoelectric. complementary). If conditions permit, my personal opinion is to install a backup gas water heater (especially if the solar pipe is long and hot water is not produced at temps), use this method for small quantities of water. professionals should not use this method (you understand, it is impossible for all family members to understand)
Like the two most common water heaters on the market, solar water heaters and gas water heaters actually have their own advantages. and disadvantages. The choice is mainly based on actual conditions and personal needs.
Solar water heaters are heating devices that convert solar energy into thermal energy, converting low temperature water into water heated to high temperature to meet people's water use. hot water in life and production.
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 heating par combustion to achieve the objective of hot water preparation. . Gas appliances.
Comparison between solar water heaters and electric water heaters
1) Easy installation: solar hot water needs to wait for a long time from the roof to indoors, and it should be installed in a place with sufficient sunlight. Places such as roofs, balconies, etc. are very difficult to install. Electric water heaters are compact and beautiful and can be installed indoors.
2)Convenience: Solar water heaters need to wait a long time from the roof to indoors, and the water pressure is not enough, which will cause difficulty in bathing; electric water heaters heat immediately when turned on, are small and easy to install.
3) Price: The advantages of electric water heaters: hot water can be set at a constant temperature , the price is cheap and it does not depend on the weather. GOODsure it uses electricity, but you can turn it on just before taking a shower, so the power consumption shouldn't be very obvious.
Solar water heater: It does not require electricity and is energy efficient, but it is highly dependent on the weather. It may not be very suitable for the rainy season in the south.
