We have and old boiler which only runs the central heating, we have no thermostat on the wall, like in my old house. So we switch it on when it gets too cold to bare or but it on a timer to come on in a morning etc.
My husband and oldest son are always warm and me and my youngest cold.
So what I want to know how cold does it need to drop inside, before the heating goes on.
I have several layers on, my husband is sat in a t shirt!
