Fireplace Heat Loss

Any ideas how to get more heat out of a large woodburning fireplace? Seems like most of the heat is going up the chimney. Room has high ceilings and stays cold.

It depends on what is important to you. The best way to get efficient heat out of a fireplace is to install an insert. If you are more into the looks rather than performance, glass doors on the fireplace opening would help a little.

Thanks for your reply. I have looked into inserts but way too expensive at this time. Any other ways to push the heat back into the house instead of up the chimney?

Hi, Director:

Here's one way to get more heat out of your fireplace: Once you have a nice fire going, or a good, strong coal bed, close your damper down to a level that will still draft, but only just above what is needed to keep the fire/coals from back-drafting/smoking into your home. This should kick more heat out of your firebox.

Note, however, that fireplaces are notoriously inefficient. I installed an insert this year, and now get SUBSTANTIALLY more heat out of the wood I burn. . . and I burn less than 1/4 of what I did in my open fireplace. The savings on wood and heating oil/natural gas/LP/electricty by not running your main heating system will pay for the insert in just a couple of years max. Might be something you want to run some numbers on.

Good luck. . . keep warm!
