What's the best way to get more heat out of an existing wood-burning fireplace?
Put an insert in it. An EPA-certified wood insert — or a sealed gas insert — with a correctly sized chimney liner turns an open fireplace from a net heat loss into a genuine heater, commonly 70% efficient or better. Glass doors, better grates, and damper habits help at the margins; nothing else comes close to what an insert does.
Why your open fireplace feels warm and heats nothing
An open masonry fireplace is a beautiful machine for sending your furnace's work up the flue. The fire feels hot from six feet away, but the draft it creates is pulling already-heated room air up the chimney the entire time — which is why the far side of the house gets colder while the fire roars. Open fireplaces can actually run a net heat loss. We see this weekly in older Asheville, Weaverville, and Hendersonville homes with big masonry fireboxes: gorgeous hearth, cold house.
Wood insert or gas insert — the fork in the road
A wood insert keeps you burning what you've always burned, but behind sealed glass with EPA-certified efficiency — heat you own outright, completely grid-independent, which is why demand jumped after Helene. We install serious wood-burning brands like Regency, along with Lopi, Jotul, HearthStone, and Quadra-Fire. A gas insert trades the wood pile for a switch: no hauling, no cold-start smoke, and with millivolt ignition it stays power-optional too. Either way the liner is non-negotiable — an insert breathing through an oversized old flue never performs to spec, so every insert we install gets a correctly sized liner. Converting to gas also means a licensed gas line, which in North Carolina is our lane and no one else's; see our [conversion guide](/guides/convert-wood-fireplace-to-gas).
The smaller fixes worth doing anyway
Short of an insert: burn fully seasoned hardwood, keep the chimney swept so creosote isn't choking the draft, and fix a warped or stuck damper so you're not leaking heat when the fireplace sits idle. All worth doing — none of it changes the physics of an open firebox. If real heat is the goal, the insert is the answer, and the math usually surprises people.
