What you get
The Duluth Forge FDSR25 Dual-Fuel Vent-Free Gas Stove is a vent-free gas stove that its maker rates at 26,000 BTU per hour and says heats up to 200 square feet.
Makers rate heating area in their own conditions, so read 200 square feet as a ceiling; the size calculator lists the closest fits for your space.
At full fire it burns about 25 cubic feet of natural gas or about 0.28 gallons of propane an hour (its 26,000 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: Electric, Gas. Never connect a gas heater to a fuel it isn't set for.
Ignition: Piezo ignition.
Also on the listing: overall dimensions of 16.9 in (D) x 28 in (W) x 26.2 in (H), a shipping or unit weight of 80 lb and ceramic construction.
