OK I know this is a weird thing to ask on a disney forum but anyway

Im having an argument with a friend over whats best to do. Leave the heating on all day/night at a set temperature say 70 and that way the house just gets constantly topped up to that temperature or switch it off when we go out and back on when we come back in. Obviously that saves the gas when we're out but then it has to heat it up from scratch again

What do you do?
