What you get
The Comfort Glow GFD4625R Dual-Fuel Vent-Free Gas Fireplace is a vent-free gas fireplace that its maker rates at 33,000 BTU per hour and says heats up to 1,200 square feet.
Treat the 1,200 square feet as the maker's best case for an open, reasonably insulated space, and check it against your room before choosing.
At full fire it burns about 32 cubic feet of natural gas or about 0.36 gallons of propane an hour (its 33,000 BTU/h divided by EIA's heat content for each fuel).
There's no vent, so all the heat lands in the room along with the water vapour combustion makes. Follow the minimum room size in its manual, and confirm vent-free heaters are allowed where you live. Vent-free vs direct-vent.
Fuel, per the listing: dual fuel. Never connect a gas heater to a fuel it isn't set for.
Also on the listing: overall dimensions of 17 in (D) x 46 in (W) x 45 in (H) and engineered wood construction.
Warranty, per the listing: 2 year manufacture defect only.
