Where should a thermostat be? Should it be in the hallway? For a long time the standard place to put a thermostat was in the hallway, but this doesn't make sense, why spend loads of money burning gas trying to keep a room you spend zero time in. When you could spend less keeping the room you actually spend most of your time in just right. Who cares if your hallway is a couple of degrees lower than the living room.
