Anyone turn the pilot light of their boiler or gas fire off in summer?
Never had a pilot light!
I'd be interested to know what proportion of new boilers have them...
None, they are all condensing.
This means there has to be a fan as the combustion products have no
buoynacy.
This means there has to be post and pre firing purges.
This mens there can be no pilot light.
