The types and functions of wall-mounted boiler fans can vary according to different classification methods and new product designs. The following are some common types of wall-mounted boiler fans and their functions in wall-mounted professional households:

1. Built-in fans: Some wall-mounted boiler designs have built-in fans. These fans are usually located inside the furnace body and are used to circulate hot air into the room. They can increase the heat dissipation effect of the wall-mounted boiler, improve the utilization rate of thermal energy, and promote the even distribution of hot air to all corners of the room.

2. Auxiliary fans: In addition to built-in fans, some wall-mounted boilers can also be installed with auxiliary fans. Auxiliary fans are usually connected to the flue of the wall-mounted boiler to help remove smoke and exhaust gas and promote air flow during combustion. They can improve the combustion efficiency of the wall-mounted boiler, reduce the retention time of smoke, and remove harmful gases and smoke.

3. External fans: Some wall-mounted boiler systems can use external fans, which are installed around the wall-mounted boiler or in the flue. The function of the external fan is to promote the circulation and heat dissipation of hot air by increasing wind power. They can improve the thermal efficiency of the wall-mounted boiler and make the heat transfer to the indoor space better.

The functions of the wall-mounted boiler fan include:

1. Increase the heat dissipation effect: The wall-mounted boiler fan distributes the hot air evenly to the room by circulating the air, accelerating the heat transfer and heat dissipation process. This helps to improve the thermal efficiency of the wall-mounted boiler and make the indoor temperature more comfortable.

2. Promote combustion and smoke emission: Some wall-mounted boiler fans can assist the combustion process, increase the air supply, and promote the completeness and efficiency of combustion. At the same time, they can also help remove combustion exhaust and smoke, and improve the environmental performance of the wall-mounted boiler.

3. Improve air circulation and uniformity: Through the circulation of the fan, the wall-mounted boiler fan can evenly distribute the hot air to all corners of the room, eliminate hot and cold areas, and improve the uniformity and comfort of the indoor temperature.

It should be noted that the types and functions of the wall-mounted boiler fan can vary depending on the brand, model and design of the wall-mounted boiler. When selecting and using a wall-mounted boiler fan, it is recommended to refer to the relevant product instructions and user manual to ensure correct operation and installation, and select the appropriate fan type according to actual needs.
