I usually turn the central heating off at 7.30 when the children go to bed. After that I usually potter around tidying up and am then in my bed by 8.30 to keep warm. I read or watch tv. I've just decorated the living room and now that it's lovely I would like to enjoy it on an evening. The room has got an electric fire. I was wondering whether it would be cheaper to have the electric fire on or keep the heating on whilst I'm in the living room on an evening.
