I've worked out that the pilot light on my old Vaillant combi boiler
uses the equivalent of 60UKP of gas per year, does this sound right?
This means a new boiler would repay in 10 years on the cost of pilot
light gas alone.

My boiler pilot light for water heating was about £1 per week two
years ago. Depends on the size and shape of the thing. The large fan
shaped ones are the most expensive that I found.
