Ventless Gas Fireplaces
Ventless Gas Fireplaces produce real flames and plenty of heat. They don't need any chimney or vent which makes them more efficient when it comes to heating. The ventless design also makes the installation much easier and more affordable.
There are 2 types of ventless gas fireplaces: all-in-one units and inserts.
All-in-one fireplaces include firebox and the burner and can be one-sided or 2-sided (see-through).
Ventless gas inserts are basically just burners that come in two styles: traditional gas logs and contemporary burners. They can be used as inserts in existing fireplaces or in building a custom ventless gas fireplace.
