Ways to keep warm
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.
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.
Put up curtains. A set of heavy curtains can block heavy drafts of air. Open them when the sun is shining and close them when it's not.
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.
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).
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.
- Check that all heat registers are adjusted open, especially where plumbing pipes might freeze. Unblock cold air returns in heated rooms (they may be blocked with furniture or rug) so heat can circulate efficiently.
Put down a rug or carpet. Rugs and carpets help prevent heat loss through the floor. They are generally warmer to the touch than wood or stone, and so
offer a warmer surface to walk on.
Add insulation in the attic and the crawl space. A lot of heat escapes through the attic, as warm air rises and cold air sinks. Make sure that your attic has enough insulation.
Cook.
- Bake cookies or a pie. Your oven will help to dry the air and heat the kitchen. The kitchen will be warm while you are cooking, and then you can have a great home cooked meal too!
- Limit cooking that gives off steam, as this will increase the humidity in the air and make your house damp. Lowering humidity in the winter time helps you to feel warmer. Water vapor (humidity) has a greater heat capacity (ability to absorb heat) than dry air. As a result, humid air feels colder in winter than does dry air and it takes more heat to make damp air feel comfortable.
Light a candle. A candle/candles can produce a lot of heat, just be mindful of where they are placed and do not leave them unattended. A trip to most any grocery store or discount store can provide you with a number of candles cheap!
- Use a candle heater. It doesn't create as much heat as a fireplace or real heater, but will create warmth very cheaply.
