Vented Versus Unvented Gas Logs

Vented gas logs offer the most realistic flame.

Vented versus unvented gas logs.

Vented gas fireplaces are not as flexible as ventless gas fireplaces in order to install a vented gas fireplace you must use a chimney or an exterior wall. Vented gas logs offer a full authentic looking flame presentation with plenty of ambiance while ventless gas logs provide a reliable and efficient heating source. Vented gas logs require a fully functional wood burning fireplace and must be burned with the damper open ventless or vent free gas logs can be installed in either a wood burning fireplace or a ventless fireplace that is rated for aftermarket ventless logs and are burned with the damper closed. They put out a constant rate of heat.

This is so that it can both take in air from the outside and then vent out the by products from the flames inside the fire box. Yes ventless gas logs heat more effectively than vented logs because there s no chimney flue for the heat to escape through. Vented gas logs are ideal if you value ambience over efficiency or if you have an existing wood burning fireplace that you want to convert to gas. Unlike vented these logs do not require a chimney or flue to operate allowing more heat to stay in your home.
