Boiler Repair London – Common Boiler Problems:

Boiler repair in London is a common necessity for homeowners dealing with heating issues. When your boiler malfunctions, it can disrupt your comfort and daily routines. London’s most prevalent boiler problems include thermostat issues, strange noises, and water leaks. A malfunctioning thermostat can lead to erratic heating or no heat at all, necessitating boiler repair.

Unusual noises like banging or whistling may indicate lime scale build-up or a faulty pump, requiring prompt attention. Water leaks can be dangerous, potentially causing damage to your property. Professional boiler fix in London is essential to address these issues promptly and restore your heating system’s efficiency and safety.

Radiators failing to heat up – Because of trapped air, dirty water in the system, or faulty radiator valves.

Low boiler pressure – When boilers continuously lose pressure or switch off, the culprit may be a leak on the central heating system or automatic air vent, a faulty pressure relief valve or a failing expansion vessel. Might be time for a boiler fix.

Flashing lights on the boiler – Often to do with the boiler electrics and circuitry. We use multimeters to locate the issue and replace the faulty component. Pumps can wear out or seize. Fans can get stuck and circuits boards can blow so a boiler repair would be recommended.

No hot water – This can be the result of several of the issues above or blockages in the boiler. We replace heat exchangers and run tests to get your showers running hot again as quickly as possible.

We can make recommendations on how to improve your boiler’s energy efficiency during a boiler repair. We also provide reminders on when your boiler or gas appliances are due for annual servicing. This gives you the peace of mind that comes with proper boiler maintenance.
