Boiler Repair vs Replacement: How to Know Which One You Need
When your boiler breaks down, the first question most homeowners ask is: should I repair it or replace it? It depends on age, cost, and efficiency. Our Gas Safe engineers in Greater Manchester will help you decide.
The Age of Your Boiler
Boilers under 8 years old: repair is almost always the right choice. Over 12 years: replacement is often more economical. Most modern condensing boilers last 10-15 years with annual servicing.
The Cost of the Repair
Use the 50% rule: if the repair costs more than 50% of a new boiler, replace. Minor repairs (diverter valve, thermocouple) are worth doing regardless of age. Major repairs on older boilers (cracked heat exchanger, PCB failure) may not be economical.
Boiler Efficiency and Your Heating Bills
Old non-condensing boilers run at 70-80% efficiency. Modern A-rated condensing boilers run at 90%+. Replacing an old boiler reduces gas bills significantly.
Frequency of Breakdowns
If your boiler has broken down more than once in a heating season, replacement is worth serious consideration. Repeated breakdowns are costly and unreliable.
When Replacement is the Right Choice
- Boiler condemned as unsafe by a Gas Safe engineer
- Back boiler (discontinued in the UK)
- Boiler is 15+ years old with a major repair needed
- Parts unavailable for discontinued models
