Common Questions

How long does a boiler last?

A cast-iron boiler can last 25 to 35 years. A modern condensing boiler usually lasts 15 to 20 with yearly service.

Can I replace a boiler with a heat pump?

Yes, with an air-to-water heat pump or a ductless system. The radiators may need upgrading, because heat pumps run cooler water than boilers.
