Comfort Glow CGWS2500 review
Comfort Glow CGWS2500 Wood Burning Stove, Fits 21" Logs
By Tom Calder
The largest stove in this group: a 2.7 cubic foot firebox that takes 21-inch logs, rated by the maker at up to 112,800 BTUs for 2,500 square feet. EPA's list shows 2.4 g/hr and 72% efficiency, and its tested output tops out at 50,470 BTU/hr, well under the advertised figure, so treat the maker's BTU number as a first-hour peak.
- Best for
- A large open-floor-plan home or a shop with a big wood supply

Who shouldn't buy this
Don't buy it if you are heating one small room: EPA notes that a properly sized stove burns less wood and gives more usable heat.
