Which is better, gas wall-hung boiler or electric wall-hung boiler?

In view of the comparison between gas wall-hung boiler and electric wall-hung boiler, it can be roughly divided into three explanations:

First, in terms of installation, gas-fired wall-hung boilers are superior to electric wall-hung boilers, because the heat source of gas-fired wall-hung boilers is natural gas, which is a renewable resource and unconstrained. The electric wall-hung boiler is different, such as a villa with a building area of more than 200 square meters. The voltage of the electric wall-hung boiler can't meet the requirements, so some customers who want to use the electric wall-hung boiler will give up buying it.

Second: in terms of use, in view of the past, the application scope of electric wall-hung boilers is larger than that of gas wall-hung boilers. General gas-fired wall-hung boilers are suitable for the use area below 200m2, while electric wall-hung boilers can be suitable for the use area of 500- 1000m2. In recent two years, with the technological innovation and research and development of gas-fired wall-hung boilers, modular boilers can be completely applied to villas, beauty salons, hotels and other large-area duplex buildings, which can not only provide partial heating but also realize central hot water circulation, killing two birds with one stone. Third, in terms of use cost, for example, the construction area is 100 square meter, and the cost of using natural gas for gas-fired wall-hung boilers is about 6-8 cubic meters, and the cost is 8 cubic meters *2.2 yuan/cubic meter = 17.6 yuan. With the same building area, when the electric wall-hung boiler is 8kw, 1kw is equal to 1 degree \, the actual heating operation for 24 hours a day is about 8- 10 hour, and the cost is 64 degrees *0.56 yuan/degree =35.8 yuan. Obviously, the figures show that the use cost of gas-fired wall-hung boilers can be said to be half of that of electric wall-hung boilers. However, this does not mean that the gas-fired wall-hung boiler has no shortcomings. In terms of environmental protection, the gas-fired wall-hung boiler is a double-layer chimney, which needs to emit some waste gas, while the electric wall-hung boiler is required to have zero emission, which is superior to the gas-fired wall-hung boiler.
