Who makes the best gas fireplace insert?
Napoleon and Kozy Heat make the best gas fireplace inserts we install — the Napoleon Oakville X4 for most conversions, and the Kozy Heat Chaska 25L when heat output is the whole point, since its blower comes standard and it's built in Minnesota for cold-climate work. Either one turns a heat-losing open fireplace into a sealed unit running 70% efficient or better.
Our two go-to inserts
The Napoleon Oakville X4 is the insert we install most — a 20,000 BTU natural-gas unit that slides into an existing masonry fireplace and seals it up tight. When a customer's real goal is heat, we point at the Kozy Heat Chaska 25L: 25,000 BTU, blower included standard rather than as an add-on, and built in Minnesota by people who understand cold winters — which reads well at 3,000 feet in Haywood County. Valor's L1, L2, and Portrait insert lines round out the board for anyone who wants radiant heat that ignores power outages entirely.
What an insert actually fixes
An open masonry fireplace can actually run a net heat loss — it pulls more warm room air up the chimney than the fire gives back. A sealed gas insert flips that: units commonly run 70% efficient or better, and the flame starts at the flip of a switch. No hauling wood, no cold-start smoke, no damper guesswork. We see this conversion weekly in older Asheville and Hendersonville homes with handsome brick fireplaces nobody uses — the insert keeps the hearth and finally makes it earn its keep. And if backup heat matters to you — after Helene, it does for most of our customers — millivolt and battery-backup ignition options keep a gas insert running when the grid quits.
The part of the job you can't see
Every insert we install goes in with a correctly sized chimney liner and, usually, a new or extended gas line — and in North Carolina, gas piping is licensed work. That's the piece a firebox showroom can't legally do. We handle the appliance, the liner, the gas connection, the county permit, and the inspection as one accountable company. If you're on the fence between a gas insert and a simple log set, come compare them burning at the showroom, or call (828) 545-0525 — we'd rather get you the right appliance than the most expensive one.
