Old boiler with a flame!

[Scud14]

It is rarely a quick return on investment to replace a reliable working boiler. The pilot light itself will cost you about fifty quid a year to run (assuming 2 cubic feet a day) and that cost just doesn't exist with a new boiler. In addition, a new boiler will save you 20%-40% on your gas bill. You will have to decide whether it is worth replacing, but a full cost analysis generally says not until it starts to break down or not meet your needs in some way.

it is cubic meter and i checked it yesterday to see the reading reached 2723720

there is another digit to the right of the 0, but it keeps moving like counter.
