WHAT FAILS HERE
Heating faults common in Mitcham
Mitcham's mix of terraced homes and conversions means engineers here are often troubleshooting combi boilers that are simply too small for the property's upgraded layout and modern expectations.
01
Insufficient hot water flow for simultaneous use
A combi boiler sized for a small flat may struggle when retrofitted into a larger converted property with multiple bathrooms. An engineer will check the boiler's output against the property's demand, test the flow rate at hot taps, and assess for any undersized pipework that restricts supply.
02
Fluctuating water pressure with multiple outlets open
In converted properties, shared or original incoming mains may not provide adequate dynamic pressure for a modern combi to function correctly. Diagnosis involves checking the cold mains pressure and flow rate at the boiler's inlet, and investigating if pressure drops occur when other flats in the building draw water.
