13. The Oven Trick
After baking or cooking anything, a useful way to heat your home is by keeping the oven door open while it cools down. You’ve already paid for the electricity to heat the oven, you might as well utilize as much of the heat as possible. However, don’t use this as an everyday way to heat your house, it’s meant only to utilize the left over heat. This can also be somewhat dangerous if you have little ones running around, so be sure your home is suitable for this.
