WHAT FAILS HERE
Heating faults common in Walthamstow
In Walthamstow, it's not unusual for us to trace a persistent cold radiator back to a loft conversion that altered the system's original hydraulic design, requiring a methodical purge of trapped air.
01
Air locks in extended heating pipework
Loft conversions and rear extensions can create high points in the pipe runs where air naturally collects, leading to cold spots in upper-floor radiators. An engineer will often start by checking the pump's operation and systematically bleeding the system from the highest points, like the new radiator in the loft space.
02
Inadequate pump performance post-extension
The original central heating pump may struggle to circulate water effectively through the added length of pipe and extra radiators in a converted loft. The engineer typically verifies the pump speed and checks for signs of wear, while also ensuring the system is balanced to prioritise flow to the new zones.
