Our heating is on a timer to come on at about 6am and off by 8am, on again at 3pm and off at 10pm. We've found that keeps us warm quite happily, although last night I turned the heating down to minimum and kept it on solid thoroughout the night. Sore throat this morning from it!
It's been on all day, everyday over Christmas however. Thankfully, we're mid-terraced, decent double-glazing, new insulation in the loft and have a neighbour who has his house like an oven - so our CH has never gone over half what it can do. Shame it's quite an old one that's likely to be inefficient. Hopefully the gas credit will cover some of the Winter costs.
