The wall-hung boiler is used as the heat source, and the floor heating radiation is used as the terminal heat dissipation method to form a floor heating heating system of the wall-hung boiler + floor heating coil. This method saves space, has relatively low operating costs, is comfortable and hygienic, and has strong thermal stability, and is deeply loved by users.

Working principle: The natural gas heats the heating water to the set temperature through the combustion of the wall-hung boiler. The heated heating water passes through the sub-catchment, and the water divider flows the heating water to the floor heating pipes of each room, and the heating water is in the floor heating coils. The flow uses radiation and convection to transfer heat to the room to achieve the purpose of heating; the heating water after heat exchange is unified back to the wall-hung boiler through the water collector, and the circulating water pump of the wall-hung boiler is used to provide power for the heating water to achieve heating.
