Ventless vs Vented Gas Burner Fireplaces


I want to put a gas "contemporary glass" burner into a wood burning fireplace (my fireplace already has gas run to it).
Should I use a vented or a vent-free burner?

Ventless can be dangerous and are outlawed in many areas due to safety concerns.
With ventless, you should not use the fireplace for a primary heat source and should open a window or door while it’s operating.

stay away from vent free fireplaces, they should not be legal.

If you read and follow the listing for a vent free unit you will have a small unit in a large room with a window open. No matter how clean it is supposed to be, you will be breathing the products of combustion. I recommend a vented unit.

Re: Ventless vs Vented Gas Burner Fireplaces


Neither are a particularly good primary heat source (the vented sets send a lot of heat out the flue and the ventless sets will put a lot of CO2 and water vapor into the room). If it's just for aesthetics, either will work. If it's a backup heat source (again, for occasional use only) the ventless sets are more efficient.

Ventless sets are prohibited in bedrooms.

For aesthetics, can always go for an electric fireplace and keep the heat off.
