- Keep windows and door closed as much as possible. If you let the cold air in, it will just cause your heater to kick in and cost you more money and energy.
- Lower your thermostat. This will make it colder, but as long as you wear warm clothes inside, you will be fine and it will cost you less money on your heating bill.
