Hi. My DP is being a pain and saying I have to stop using the heating so much. It takes so long to heat up to 20 degrees (which I think is normal temp.) Normally the house is at 17 or 18 degrees. Heating as been on for 3 hours this morning and it's still 18 degrees. We have a fairly big old house with crap windows and he keeps telling me we can't afford new ones.
What sort of temp do people keep their houses at and does anyone else have this problem?
