I was trying to avoid it for a little long until at least November but it's just so cold. 8 degrees here in the North. I have my thermostat set at 18 and it's kicked in a few times over the weekend. I have a young child as well so I don't want to scrimp on the heating but I'm so worried about how much the gas bill over winter.
Is it actually cheaper to have it set at a temperature or should I just program it to come on at certain times during the day?
