If you're looking for sleek and ultra-modern fireplace, then consider Starfire Direct's Alterna vent-free fireplace. It allows for the functionality of a traditional fireplace without the hassle of setting up and cleaning a ventilation system. While we do recommend keeping your glass door open for proper combustion, this fireplace doesn't need to be connected to a flue or other system, cutting down on installation time and cost. 

Our vent-free fireplace is compatible with fire glass, a lovely alternative to wood, coals, and other fire media. Ventless fireplaces have come a long way since the days of mimicking wood burning fires with ceramic logs. The fire glass used with this fireplace enhances its modern look, matching any home's contemporary design scheme.

Our Alterna vent-free fireplace is very simple to maintain and requires very little cleaning. This is because fire glass doesn't leave ash or soot and only needs to be rinsed with water from time to time. The unique burners of this vent-free fireplace keep the actual burner free of fire glass meaning virtually no clean up.

It's an efficient way to warm your home, as well. It draws in air from your home at a 99.9% combustion rate to cut down electricity bills while adding colorful warmth to your space. Let the Alterna vent-free fireplace increase the comfort in your home with its modern elegance.
