Now that it's getting colder outside I'm thinking about the cost of heating my apartment. It's a one bedroom place but the living room and kitchen are both pretty big and sadly the apartment is very badly insulated. Even though it hasn't been TERRIBLY cold yet (as in it hasn't yet hit 0) it's been necessary to keep my gas heater running almost nonstop to keep the apartment at a comfortable temperature (and I'm still wearing sweaters and using a blanket on the couch at night). When it starts getting colder I'm just terrified about what this will do to my gas bill since it's a gas heater. The heater is located in a small hallway between my living room and the bedroom and there's a small arch between the hall and the living room. I've been thinking about moving my TV into the bedroom and hanging a blanket over the arch between the hall and the living room so that I'm heating just the bedroom and the bathroom which means I can burn less gas and keep my bill lower. Of course, there's a problem. The heater's side is a foot (almost exactly) from the edge of the arch, where the blanket would be hanging. The warning label on the heater says to keep furniture and clothing away from the surface because of the surface temperature but it doesn't state the distance that things need to be kept so I have no idea how dangerous this would be. Obviously I don't want to do anything that would set fire to my apartment but I also don't want to end up with hugely expensive gas bills. If this is entirely too dangerous should I just keep the gas running on low and buy a space heater for my bedroom?
