Vent-free gas products remove the need for a chimney or venting, allowing you to install your heating appliance nearly anywhere. An efficiency of 99% means vent-free systems are unmatched in delivering available heat directly to your room. Tens of millions of households worldwide enjoy the safe comfort and convenience of vent-free gas heating products.
Vent-free gas fireplaces look just like traditional fireplace, and come in all shapes and sizes. Because there’s no chimney or vent, they can be installed into any interior or external wall at a fraction of the cost of a traditional fireplace installation.
A vent-free gas fireplace insert installs within an existing masonry or factory-built fireplace, turning a messy, inefficient decoration into an efficient heat source. Inserts deliver the unbeatable heating efficiency of vent-free gas logs, and some offer a blower for improved heat distribution.
Space heaters can be permanently installed on a wall or mounted on a floor stand. As the most cost-effective and compact vent-free appliance, space heaters offer the most installation flexibility.
Installed in a traditional masonry or listed factory built fireplace designed for wood burning, cent-free gas logs operate with the fireplace damper closed, which allows heat to stay in the room and not go up the chimney.
They’re easily mistaken for wood stoves, but cost considerably less to install and operate; with a vent free gas stove, there’s no flue, no hole in the ceiling or wall, no wood to chop, no soot, and no ashes to clean up.
To document how vent-free gas products affect indoor air quality, the American Gas Association Research (AGAR) Laboratories† performed an extensive, independent scientific study. They ran trials with real vent-free products in a real home — the AGAR research and demonstration house. AGAR scientists tested the levels of all five major contributors of indoor air quality — oxygen, carbon monoxide, carbon dioxide, nitrogen dioxide, and water vapor (humidity) — against the latest indoor air quality guidelines and recommendations.
