It's getting colder, so I thought I'd pose the question: when do you feel the need to turn it on (if you have it)?
Since last week mine has been set to come on for 1 hour in the evening, between 7 and 8, just to dry clothes really as I have no outside area to hang stuff. It's set extremely slow so the radiators that are on get... "tepid".
It's unlikely that I'll turn them up, or on further until some time in November... basically until the cold starts to affect my typing.
I use sod all gas as a result - gas bill win!
However, a little tip for everyone - now is a good time to at least check your CH does indeed work - if there's a problem then you can get it sorted before you can't do to be without.
