WHAT FAILS HERE
Heating faults common in Ruislip
Working in Ruislip's well-kept original homes often means encountering heating systems that have been reliably topped up for years, quietly accumulating the internal corrosion that eventually demands a thorough clean-out.
01
Cold spots and noisy radiators despite bleeding
In systems that have been in operation for decades without a flush, magnetite sludge settles in radiator bottoms, blocking heat transfer and water flow. An engineer will check for a black, magnetic sludge by draining a small amount from a radiator drain-off point and using a magnet.
02
Pump failure and boiler lockout due to sludge
Heavy contamination can cause the central heating pump to seize or overwork, leading to overheating and boiler shutdowns. Diagnosis involves inspecting the pump isolator for black water, checking system water clarity in the feed-and-expansion tank, and assessing if a power flush is required to restore flow.
