I know a few weeks ago lots of us were holding off switching the heating on. We're lucky enough to be able to light the fires in the livng rooms, but it's 2 degC out there right now, and even I think it's too cold in the rest of the house.
Plus, my husband has started putting the heating on constant every time I look the other way (all day yesterday, while the house was empty. grrr.) so I think it'll work out cheaper to have it on timer... 1 hour in the morning, 2 hours in the evening. Now I just to make sure that the radiators are switched off in empty rooms. Sigh.
How about the rest of you? Have you got the boiler fired up? Hot water bottles at the ready?
