Home decoration kitchen appliances can’t be lacking is the hot water equipment. What is the difference between a gas water heater and a gas wall-hung boiler? A detailed analysis is as follows:

1. Functionality

The main function of the gas water heater is to solve the hot water problem at home. For the remote toilet, it can realize the purpose of timely hot water output according to the installation of circulating water pump and time controller. According to the requirements of different users, choose water heaters of different power; The main function is heating and domestic hot water. After solving the house heating problem, it can also solve the domestic hot water problem. It is not recommended to install a circulating water pump for hot water circulation for dual-function wall-hung boilers. Single-function wall-hung boilers need to be equipped with a water tank. Hot water circulation can solve the problem of secondary heating and hot water at the same time.

2. Service life

The state stipulates that the service life of the water heater is 8 years, and it needs to be replaced if it exceeds the time limit of use. However, many users' water heaters are over-aged, and the water heater is not easy to maintain. The result is the low efficiency of the water heater and the increase in the cost of natural gas used. . The design life of wall-hung boilers is as long as 20 years, and the service life of condensing wall-hung boilers can be 30 years. Wall-hung boilers have a relatively large impact on heating. Therefore, users who install heating will attach great importance to the maintenance of wall-hung boilers. The components of the system are maintained and used. The service life can realize the service life of the design.

3. Water temperature constancy

The water heater directly heats the tap water according to the internal furnace. When the hot water is used, there will be high-temperature baking tap water in the furnace. When the hot water is used again, a short period of high-temperature hot water will come out. At this stage, most of the wall-hung boilers on the market adopt plate-exchange heating for hot water heating. Cross heat transfer between high-temperature heating water and tap water inside the plate exchanger (heat exchange without water exchange), when the hot water is terminated There is no continuous high temperature heating inside the plate exchanger, so the hot water produced by the wall-hung boiler has a constant temperature.
