WHAT FAILS HERE

Heating faults common in Chiswick

In Chiswick, many elegant period homes have been vertically expanded, which can strain the original heating layout. We often find the system needs re-balancing to accommodate the new thermal load upstairs.

01

Cold upper-floor radiators after loft conversion

Extensions often add radiators beyond the original system's hydraulic design, creating weak circulation points. An engineer will check for airlocks at the new high point and verify the pump's capacity to push water up to the added circuit.

02

Gurgling noises from extended pipework

The new pipe runs in converted spaces can create air traps, especially if the feed and expansion pipe location is no longer optimal. Diagnosis involves checking the automatic air vent in the loft space and manually bleeding the highest radiator in the new zone.
