Why pick gas inserts
Modernize Your Old Hearth
Most older masonry fireplaces are heat thieves — they suck warm air out of the room and send it up the chimney. A gas insert solves that completely. It slides into your existing fireplace opening, seals the chimney, and converts your decorative hole-in-the-wall into a high-efficiency heater.
We carry the Heat & Glo Provident at the entry tier (still a major upgrade over an open fireplace), the Chaska and Supreme series in the middle, and the Escape and Nordic series at the top — efficient enough to actually heat the rooms around the fireplace.
Most insert installs take one day. We handle the gas line, vent liner up the existing chimney, and trim work. You light it on the way home from work and the room is warm by the time you eat dinner.
Why choose a gas inserts
What You Get
Stops your chimney from stealing heat
Closed-system inserts seal the flue, eliminating drafts and turning a heat-loss source into a heat source.
Drops into your existing opening
No demolition, no reframing. Most installs are a one-day project.
Runs in a power outage
Battery-backup ignition keeps you warm when the grid goes down.
Hides the work, keeps the look
A surround panel covers the install seam — the front looks like a fireplace, but underneath it's a modern appliance.
