How long does a residential boiler last?

A well-maintained boiler typically lasts 15-30 years. Annual maintenance — including cleaning, safety testing, and component inspection — is key to reaching the upper end of that range.

What are signs my boiler needs repair?

Strange noises (kettling, banging), uneven heating, increased energy bills, water leaks around the boiler, or the system cycling on and off frequently.

Do you install high-efficiency boilers?

Yes. We install high-efficiency condensing boilers that can achieve 95%+ efficiency ratings, significantly reducing your heating costs compared to older standard-efficiency units.
