WHAT FAILS HERE
Heating faults common in Eltham
Eltham's many subdivided properties mean we regularly see combi boilers that are simply undersized for the actual number of occupants and bathrooms now present.
01
Poor hot water pressure when multiple taps run
A combi boiler sized for a smaller original property may struggle to meet the simultaneous hot water demand of a converted flat with an extra bathroom. An engineer will assess the boiler's kW output, check the cold water mains flow and pressure entering the property, and evaluate the installation's pipework for restrictions.
02
Fluctuating shower temperature in converted dwellings
This is a classic sign of a combi boiler being overwhelmed by conflicting demands, like a shower running while a washing machine draws hot water. The check involves testing the boiler's plate heat exchanger for scaling, verifying the thermostatic shower valve is functioning, and confirming the system's water pressure is stable under load.
