7 Signs You Need a New Boiler
Age, rising bills, repeated repairs, leaks and noise all point toward replacement.
Boilers rarely fail without warning. Watch for these signs to replace on your schedule.
The warning signs
Age over 12–15 years, rising gas bills, frequent repairs, leaks, kettling noise, slow warm-up and yellow flames all signal it's time.
Repair vs replace
If a major repair approaches a third of a new boiler's cost on an older unit, replacement usually makes more financial sense.
Key takeaways
- Age 12–15+ years
- Rising bills and frequent repairs
- Leaks, noise and slow warm-up
- Plan ahead of a breakdown
