A Ventless fireplace is a vent-free fireplace with no chimney. Ventless fireplaces are natural gas or propane fired fireplaces. Because Ventless fireplaces don’t need any vent or chimney, they are much cheaper to install than vented models, and can be placed in rooms where other fireplaces cannot be installed.
Ventless (vent-free) fireplaces have an oxygen-depletion sensor to shut off the gas if the oxygen level ever drops below a preset level. Additionally, their burners produce very low levels of carbon monoxide.
Ventless fireplaces have very high efficiency ratings because all the heat is recirculated into the room. On the other hand, Ventless fireplaces have smaller and less realistic fire than other fireplaces. They are require you to leave a window slightly open during use.
How Ventless Fireplaces Works
The working principle of a vent less gas fireplace is quite simple. When the system is installed, the fire is adjusted to burn at optimum efficiency minimizing the release of harmful carbon monoxide gas and moisture to a level that is safe enough to be vented into the home.
Ventless Fireplace Buying Guide
