10 Common Central Heating Problems in Fulham & West London – And How to Fix Them
Practical advice for homeowners dealing with boiler faults, cold radiators, and heating issues across Fulham and West London.
1. Cold Radiators or Uneven Heating
If some radiators remain cold or only heat in patches, heat isn’t circulating properly. This is often caused by trapped air, sludge buildup, or a failing pump — common in older Fulham properties.
How it’s fixed:
Bleeding radiators helps with trapped air. If sludge is present, our engineers carry out power flushing to restore circulation. Faulty pumps are repaired or replaced.
2. Boiler Not Turning On
A boiler that won’t start may be suffering from pressure issues, thermostat faults, or internal failures.
How it’s fixed:
Our Gas Safe engineers diagnose faults safely and restore heating without unnecessary replacements.
3. Strange Noises From Boilers or Radiators
Banging or gurgling noises usually mean trapped air, limescale, or pump issues — common in hard water areas like West London.
4. Low Boiler Pressure
Low pressure stops boilers heating efficiently and often points to leaks or faulty valves.
How it’s fixed:
We locate leaks with non-invasive tools and restore correct pressure safely.
5. Radiators Hot at the Top, Cold at the Bottom
This indicates sludge buildup restricting water flow.
How it’s fixed:
Power flushing removes debris and restores full radiator heat.
6. Faulty Thermostat
Unreliable heating often stems from thermostat faults.
How it’s fixed:
We repair or upgrade thermostats to modern, efficient controls.
7. Frozen Condensate Pipe
Frozen condensate pipes can shut boilers down during cold snaps.
How it’s fixed:
Pipes are safely thawed, insulated, or rerouted.
8. Leaking Boiler or Pipes
Leaks reduce pressure and cause property damage.
How it’s fixed:
Accurate leak detection and lasting repairs.
9. Noisy or Failing Circulation Pump
Pump failures prevent heat reaching radiators.
How it’s fixed:
Air removal, flushing, or pump replacement.
10. Inconsistent Hot Water Supply
Often caused by limescale or boiler issues.
How it’s fixed:
Boiler servicing, flushing, or system upgrades.
