WHAT FAILS HERE
Heating faults common in Dulwich
Dulwich properties often present a mismatch between elegant period conversions and the practical demands of modern living, with combi boilers frequently undersized for the actual number of occupants and bathrooms.
01
Poor hot water flow with simultaneous demand
Combi boilers retrofitted into flats or converted houses can struggle when multiple outlets are used at once, as the original mains supply or boiler output may be insufficient. An engineer checks the dynamic water pressure, the boiler's hot water delivery rate, and assesses whether a system boiler with a cylinder would be a better match for the property's usage.
02
Fluctuating water temperature in showers
This is a common symptom in properties where a single combi boiler serves several bathrooms, as drawing cold water elsewhere affects the flow rate through the boiler. Diagnosis involves testing the shower valve, checking for flow restrictions, and evaluating the boiler's minimum and maximum modulation capabilities against actual demand.
