9. Cover up tile and wood flooring
Much of your home’s heat can escape through your tile and wood floors. Consider installing some carpet to retain that warmth.
If that’s not possible, pick up several large rugs and runners. You can use them to cover up most of the exposed areas and trap in more heat.
Plus, your feet will be warmer on plush fabric than they will be on cold tile or wood. Everyone wants to have toasty toes in the wintertime!
