While it is certainly less expensive to purchase a ventless gas fireplace, there is no equivalent model available to match the specs and appearance of the Empire Tahoe Luxury RF model. Personally, I would recommend sticking with direct vent for a few reasons; you can see a list of pros and cons in our Gas Fireplace and Stove Buying Guide
. If you still want a vent-free recommendation, I would suggest the Empire Vail vent-free series; please see details below. Empire Vail Vent-Free Gas Fireplaces
. These are available in 24", 26", 32" and 36" sizes.
