From an energy saving point of view, of course, solar water heaters are much better. They cost nothing for several months of the year. However, when there is no sun, water boils very slowly and uses a lot of energy. electricity. If conditions permit, it is best to install two water heaters, install valves on the water pipes for switching, and use gas water heaters when there is no sun .
From a savings perspective, is it better to use solar energy or gas water heaters for households? (Gas is natural gas)
First of all, in terms of energy type, solar energy is clean and green energy with low acquisition conditions. Gas water heaters are a secondary exchange energy, which is more environmentally friendly than solar energy. Original gas, but not as good as solar. More direct and broader coverage.
Second, in terms of expenses, solar energy is more economical than gas. You have to pay the required fees for gas, while solar power is free and a one-time investment that won't be used. It will take a long time to "get the money back".
However, gas water heaters are not affected by weather conditions and geographic location. If the location is in a particular area, for example, there are more rainy days than sunny days all year round, it is more appropriate to use them. install a gas water heater. But most areas are still more suitable for using solar water heaters, which are more energy efficient and cost effective than other water heaters.
But most of the solar energy we use today is greatly affected by the seasons. Using solar energy in winter is also a headachesummer. There are many things to pay attention to. continued rainy weather which will affect hot water usage in my home. A kind of ceramic solar installed some time ago is much more worry-free than the balcony wall hanging installed in the community now. He replaced my balcony railings. With the current solar heat collection system, there is no need to worry about safety and aesthetic issues because it is a ceramic solar air conditioning system. The problems of pipes drying out and bursting no longer exist. And it is also equipped with auxiliary electric heating, which solves the problem of hot water supply on continuous rainy days.

Solar energy is great!
The calculation is as follows:
The general price of solar energy is about 3,000 yuan,
the general gas price is 800 yuan
p>The price difference is 2,200 yuan
p>Based on 80L of water per day (not enough for a bath in winter)
Gas requires about 0.5 cubic meters, which is more than 1 yuan
At least 400 yuan per year
