WHAT FAILS HERE
Heating faults common in Carshalton
Carshalton's characterful conversions can present a classic mismatch, where the original building fabric meets modern, high-demand living in a way the heating system wasn't designed for.
01
Poor hot water pressure in converted flats
A combi boiler sized for a single family home is often inadequate when the property is split into flats, struggling to deliver sufficient flow to multiple outlets. An engineer assesses the boiler's kW output against the property's demand, checks for undersized gas or water supply lines, and tests dynamic water pressure.
02
Temperature fluctuations during simultaneous use
In a multi-occupancy conversion, someone showering while another taps runs can overwhelm a standard combi's heat exchanger. The diagnostic focus is on checking the boiler's modulation performance, the condition of the plate heat exchanger, and whether a system boiler with a cylinder would be a more suitable retrofit.
