The biggest difference between vented and vent-free gas log sets is how they operate and the purpose they serve.
Vent-free gas logs are designed to provide supplemental heat and do not require a chimney or vent to the outside. Because they retain more heat inside the home, they’re an efficient option for adding warmth to a room.
Vented gas logs require a functioning chimney or vent and are primarily designed for ambiance. While they produce the realistic look and sound of a traditional wood-burning fire, much of the heat is vented outdoors.
Both options are available from Euliss Propane. We carry CSA-certified Heatmaster gas log sets in vented and vent-free configurations and can help you determine which style best fits your fireplace, home and comfort preferences.
