How old is my boiler?

Boiler serial number and manufacture date

Which serial number should I use to date a boiler?

Use the boiler manufacturer’s appliance identification. A pump, burner or control can have its own serial and replacement history. For a combination boiler, keep the full model so the correct product family is identified.

Can a service sticker prove the boiler’s age?

A service sticker records work done at a particular time. Keep it as maintenance history, but use a printed manufacture date, supported serial format or manufacturer confirmation to date the boiler.

A boiler typically lasts 15 to 30 years in normal household use. Once one reaches 15 years, it is worth budgeting for a replacement.

Have it serviced yearly and watch the pressure gauge; frequent topping up points to a leak.
