Diagnosis in SW7
Central Heating Problems We Diagnose
Heating not coming on
Check thermostat settings, time programmer and zone valve operation. If the boiler fires but heat doesn't reach radiators, the zone valve or pump has likely failed. Zone valves typically last 10-15 years — a common failure point in London properties.
Some rooms hot, others cold
System imbalance is very common in London Victorian terraces where pipework runs and radiator sizes haven't been recalculated since the original installation. We balance lockshield valves so every room reaches temperature without any radiator over- or under-performing.
High gas bills but poor heating
A sludged system makes the boiler work harder, burning more gas for less heat. A power flush and magnetic filter typically cuts heating bills by 15-25% and reduces boiler wear. We test efficiency before and after with flue gas analysis.
London system age: many London properties still have central heating systems installed in the 1980s or 1990s. Upgrading controls (adding TRVs, replacing programmers with smart thermostats) can improve comfort and cut bills without replacing the entire system.
