#1 – Close all of your windows properly. This includes making sure storm windows are installed and closed in place if you have them. Windows should be latched. Open them during the day if the outside temperature is higher than the inside temperature.
#2 – Use cheap clear shower curtains over the windows that receive sun light. This will keep the cold air out, and the warmth from the sun will heat your house without cold air coming in. You could also cover your windows with clear plastic sheets and make it airtight.
#3 – Seal your doors. Check around the door frame and also under the door. You may want to buy weather stripping or a door sweep. Again, at minimum, make a draft dodger or stuff a towel at the bottom of the door.
#4 – Let as much sun hit your house as possible. Check for obstructions (e.g. plants, sheds) that might keep the sun’s rays from reaching your house. Remove items leaning against walls on the sunny side of your house. (Ideally, put them back again at night for additional insulation).
#5 – Close off any unused rooms. The closed door makes that room another barrier between you and the frigid outdoors. It also stops air from circulating as much, which reduces heat loss. Home improvement stores sell magnetic register covers to ‘shut off’ forced air furnace registers in unused rooms. That way when the heater does click on, only the registers in the rooms you use will pump out heat. This makes for more efficient use of the heater.
