　　Water heater burning gas is mainly for the user in a short period of time to supply hot water.

　　It is primarily through the burning of gas transfer heat water, the water reaches a certain temperature. With the improvement of people's living standard, most users are using gas water heater.

　　因为使用燃气做燃料比使用煤炭效率高很多，并且花费相对较低、对环境的污染也较少。但是燃气热水器只能单一的提供热水，并不能满足人们对此类产品功能的满意度。

　　Because use than the use of coal gas as a fuel efficiency is much higher, and relatively low cost, less pollution to the environment. But gas water heater can only single provide hot water, and can't satisfy people's satisfaction function to this kind of product.
