Back Boiler Replacement Estimated Saving £170 per annum.

The most recent work on www.conserveandsave.co.uk has been on the heating system which, including cooking, accounts for approximately 50% of the project houses energy cost. One of the key components of this is the central heating boiler which is definitely of low efficiency because its age and obsolete design. For example, it

1. Has a continually lit pilot - Modern boilers don't.
2. A simple heat exchanger of approx 70% efficiency - 90% or higher can now be expected
3. Draws its combustion air from inside the house - Modern systems have an integrated intake with flue.

If the boiler could be replaced with a more modern design the estimated saving is approximately £170/year. This is an attractive project to consider although if the replacement cost was £1000 including labour, the payback would be 5 - 6 years. However, this doesn't take into account fuel price increases so the payback time would probably be further reduced.

It's a pity the government have replaced the boiler scrappage scheme because it's still a large sum to find!
