Age alone does not decide whether a boiler should be replaced. Fault type, repair cost, parts availability, reliability and the condition of the wider heating system all matter.
Understanding the issue
Age alone does not decide whether a boiler should be replaced. Fault type, repair cost, parts availability, reliability and the condition of the wider heating system all matter.
What to check
A modest repair on an otherwise sound appliance can be sensible. Repeated expensive faults or obsolete parts may shift the balance toward replacement.
When to get advice
Compare the total expected cost and disruption, and consider controls and system condition at the same time rather than focusing only on the boiler box.
