Gas Fireplace Inserts
A gas fireplace insert is the most efficient way to bring a cold, drafty masonry fireplace back to life without the cost or disruption of a full rebuild.
Inserts drop into your existing firebox and convert it into a sealed, high efficiency heat source rated between 70 and 85 percent AFUE, compared to the 10 to 15 percent efficiency of a traditional open wood fire. Every gas fireplace insert at Fireplace Insider ships free nationwide with white glove delivery, comes from a factory authorized brand, and is backed by our price match guarantee.
We carry direct vent, B vent, and vent free gas inserts from Napoleon, Heat & Glo, Superior, Majestic, Empire, and other premium hearth manufacturers. If you are unsure which model fits your fireplace opening, our free insert sizing calculator will narrow your options in under two minutes.
