Back Boiler Replacement - Time to Upgrade for Safety & Savings
Back boilers are outdated, inefficient, and increasingly unsafe. If yours is over 15 years old, you’re wasting £600+ annually and risking carbon monoxide exposure.
What You'll Save
Replacing a back boiler with modern combi:
- Annual saving: £500-£700
- Payback period: 4-6 years
- 10-year total saving: £5,000-£7,000
- Plus: Reclaim valuable living space
Why back boilers cost you more:
- Only 60-65% efficient (modern boilers: 90%+)
- Heat lost up chimney constantly
- Takes longer to heat water
- Harder to control temperature accurately
Safety Concerns - Why Replace Now?
Carbon monoxide risk:
- Back boilers produce CO through chimney
- Blocked flues cause dangerous CO buildup
- Older models lack modern safety cutoffs
- Annual deaths in UK from faulty back boilers
Fire hazards:
- Gas pipes run behind fireplace
- Deteriorating seals over time
- Limited access for proper servicing
- Parts increasingly unavailable
Warning signs to act immediately:
- Yellow or orange flame (should be blue)
- Sooty marks around fireplace
- Excessive condensation on windows
- Pilot light keeps going out
- Strange smells or sounds
- Headaches, dizziness, nausea (CO symptoms)
Don’t wait: Back boilers are no longer manufactured. When yours fails, emergency replacement costs 30-40% more.
