Turning down your thermostat in the winter
Turning down your thermostat by just a few degrees to 68 F in the winter can save 5-10% on your overall heating bill.
If you think about it, this makes sense. By turning down the thermostat to a more reasonable temperature in the colder months, there is less of a difference between the air outside and the air inside. Keep in mind that insulation only slows the transfer of air, which moves from warm temperatures to colder ones. The closer the temperatures, the less air will move.
Additionally, there is less of a demand on your furnace. So besides the thermodynamic aspect explained above, the furnace will be “on” for less time. And it will not turn on as often to maintain the temperature. If your furnace runs less, it will not use as much fuel. This translates directly to lower energy bills.
Your actual savings may vary depending on various factors including fuel cost and your home’s energy usage. For example, if you have poor insulation you can still expect to save money on your energy bills than if you kept the temperature higher, but you can not expect the same savings as someone who has better insulation. In other words, you will save money on your heating bill than if you kept the temperature higher.
You can always mitigate how to combat a colder room instead of turning up the heat on your thermostat, if the temptation strikes:
- use blankets
- dress warmer (sweaters, layers)
- use space heaters
