Most engineers recommend an annual service, but this can vary based on usage and the boiler type.

Common causes include leaks, faulty pressure relief valves, or issues with the expansion vessel.

Frequent breakdowns, unusual noises, inefficiency, and higher energy bills are common indicators.

Engineers may suggest upgrading to a more efficient model, bleeding radiators, installing thermostats, or adding insulation.

This could indicate trapped air, low water pressure, or a buildup of limescale or sludge.

Engineers often troubleshoot ignition issues, electrical problems, or faults with the thermostat.

This may be caused by a faulty thermostat, broken diverter valve, or issues with the heat exchanger.

The lifespan of a boiler is typically 10-15 years, depending on maintenance and usage.

Condensing boilers are highly efficient because they capture and recycle heat that would normally be lost. Engineers are often asked if upgrading to this type of boiler is beneficial.

Engineers provide estimates based on the type of boiler, the complexity of installation, and any additional work required.

Due to safety regulations and the complexity of installation, only qualified professionals should install boilers.
