Keeping your house warm during the winter can get expensive. That cost is expected to be even higher than the last two winters according to the U.S. Energy Information Administration due to expected colder temperatures and costlier energy prices. Suggested fixes for keeping your home well insulated can also be a hit to your wallet. Better Business Bureau® serving Eastern Oklahoma is sharing a few tips to keep your home warm without breaking the bank.1. Let the sunshine in: If it's a sunny day, use the earth's natural heat source to warm up your home. Open curtains and blinds during the day to save money on both lighting and heating. Close the curtains as soon as the sun sets to help keep your home insulated against the cold night air. Invest in good curtains that are lined, like sun blocking curtains for best results.2. Let the oven do double duty: Using the oven can warm up a room. While it may be ill-advised during the warmer months, because it causes your air conditioning unit to work harder, it is perfect for colder months. When you’re done cooking or baking in the oven, leave it ajar as it cools down, allowing the heat to spread throughout your home.3. Cover floors with area rugs: Warm air can be escaping through your floorboards but insulating under your house could be costly. Use plush area rugs to insulate your floors and keep your feet warm. 4. Keep doors to unused rooms shut: Rooms that are not currently in use don't need to be warm. Keeping the doors closed cuts down on the amount of spaced that needs to be warmed by your heating unit and helps insulate the rest of the house from cold air. 5. Use your fireplace or seal it: Sitting around a toasty fire can be a perfect way to stay warm during the winter. Rearrange your furniture, so your favorite chair gets the best warmth from the fire, but be careful not to get too close as it can be a fire hazard. If your fireplace is decorative, make sure it is sealed off thoroughly as it can be an area where warm air escapes and cold air enters the home.
