How to connect the fan coil to the wall-mounted boiler
In domestic or commercial heating systems, the connection of the fan coil unit to the wall-mounted boiler is a common technical problem. The correct connection method not only improves heating efficiency, but also ensures stable operation of the system. This article will introduce in detail the connection method between the fan coil unit and the wall-mounted boiler, and provide hot topics and hot content in the past 10 days as a reference.
1. The connection principle between fan coil unit and wall-hung boiler

A fan coil unit is a device that uses forced convection heat exchange by a fan and is usually used in central air conditioning or heating systems. Wall-hung boilers are key equipment that provide heat sources. The connection between the two is mainly achieved through the water system. The following are the basic steps for connection:
| steps | Operation content |
|---|---|
| 1 | Confirm the location of the water outlet and return outlet of the wall-hung boiler |
| 2 | Connect the water inlet pipe of the fan coil unit to the water outlet of the wall-hung boiler |
| 3 | Connect the return pipe of the fan coil to the return port of the wall-hung boiler |
| 4 | Install a circulation pump (if needed) to ensure water circulation |
| 5 | Check whether all interfaces are sealed to avoid water leakage |
