Pros
- Turns an open masonry fireplace into a real heater for up to 1,200 sq ft
- Blower and faceplate come in the box, so there is nothing extra to buy to finish it
- Tested at 73% efficiency, so far more heat stays in the room than with an open fire
- Takes 18 in logs
Cons
- The blower needs an outlet, and without power much less heat leaves the fireplace
- Not approved for mobile homes
