Maintain your fireplace


Use your fireplace wisely

An open fireplace is one of the most inefficient heat sources in your home, as it draws warm air up the chimney and pulls cold air into your home.

The cost to upgrade the efficiency of your fireplace, or to purchase an energy-efficient one, varies widely. With some simple maintenance you can make your existing fireplace more efficient and cut down on wasted heat and make your home more comfortable.

If you're not ready to give up your old fireplace, make it as energy efficient as possible.

  1. Check the damper periodically to ensure it can close tightly and is in good working order. Close the damper tightly when the fireplace is not in use.
  2. If you don't use your fireplace, seal the damper tightly with weatherstripping and fill the chimney with insulation. Remember to remove the insulation if you decide to use the fireplace again.
