Make your fireplace more energy efficient

While a fireplace should certainly not be a primary source of heating, if you have one, you may use it for “atmosphere,” particularly during winter holidays and when you have guests in your home. Here are suggestions for making your fireplace as efficient as possible:

  • Keep damper closed unless a fire is burning; otherwise, it’s like you have a window wide open
  • When using the fireplace, reduce heat loss by opening dampers in bottom of firebox or open nearest window slightly, about 1 inch, and close doors leading into the room; lower thermostat setting to between 50 and 55 degrees
  • Install tempered glass doors and a heat-air exchange system that blows warmed air back into the room
  • Make seal on fireplace flue as snug as possible
  • Buy grates of C-shaped metal tubes to draw cool room air into the fireplace and circulate warm air out
  • Caulk around the fireplace hearth
  • Plug and seal the flue if you never use the fireplace
