All right, now we're talking.

So, wood fireplace. Two problems. Number one, most of the heat goes up the chimney. Solution for that is a fireplace insert. Inserts have heat exchanger tubes above the firebox, so that heat otherwise wasted in the smoke can be recovered and sent into the room via a fan.

Second problem: intake air. Fire needs oxygen; a fireplace pulls air from the room it's in. This makes the house negatively pressurized, so you start sucking cold air from outside from every crack and creating cold drafts. Solution for that is a fireplace insert that has a separate outside air intake. It has a sealed combustion chamber so house air that's already been heated stays in the house. Sadly, not all inserts have outside air intakes, so you have to do your homework when selecting yours.

Stuck in the 70's

Our house was built in the 70's. It had an inefficient wood burning fireplace. In the winter (when we were not burning it) it would always be at least 10 degrees cooler in that area.

Two years ago we had a wood burning insert installed. It cut our heating bill dramatically. And now we can heat the whole house with just the fireplace if we want.

One caveat. I would suggest you hire a professional to install it. If you are considering doing this DIY, check with your homeowners insurance. If something goes south and you have a fire, it could be an issue.
