Cleaning fan coil and water filters: how performance is affected

Maintenance of both the fan coil air filter and the hydraulic circuit water filter is essential for proper operation.

Fan coil air filter

When clogged, air flow is reduced, noise increases, and thermal or cooling performance drops.

Water filter

Impurities in the hydraulic circuit can restrict flow to fan coils or underfloor heating.

Impact on the heat pump

Low water flow can increase the ΔT and cause alarms or frequent shutdowns.

Periodic check

The cleaning frequency depends on the environment, water quality, and the manufacturer's instructions.
