I woke up to my house being 13.5oc. I was brought up with no heating and scrapping ice off the inside of our windows so I'm us to being in a cold house. But I always remember how hard that was and how everyone else house was way to warm, I still feel lile that now. It doesn't take long to feel ill in a hot house, thought I can cope well in 35 plus heat in summer lol. I have to try to remeber that I don't want kids to feel that dread of being cold when they get up in the morning and seeing their breath inside isn't a good memory to have even though it can be fun for a few minutes. But I also carn't afford to heat the house to 18oc everyday. Our house usally stays at 15 and no one complains.
