WHAT FAILS HERE
Heating faults common in Hayes
Hayes sees a lot of demand for combi installations in older buildings that have been subdivided; the mismatch between the original infrastructure and modern expectations for instant hot water is a frequent source of complaints.
01
Poor hot water flow when multiple taps are used
A combi boiler sized for a smaller original property can struggle when retrofitted into a converted flat with an additional bathroom or kitchen. The engineer will test the dynamic water pressure and flow rate at the boiler's cold inlet to see if it meets the unit's minimum requirements.
02
Hot water runs lukewarm or cuts out during a shower
This is a classic sign of a boiler's hot water demand exceeding its capacity, often in properties where an electric shower has been replaced with a mixer fed by the combi. We check the boiler's output temperature setting, the thermistor readings, and whether the mains water pressure is sufficient during peak demand.
