I see a few people on here putting a freestanding stove in the fireplace opening . Is there an advantage to this? I'm sure gaining an ash drawer would be a bonus . I have an open fireplace myself and am looking to get some real heat out of it . It seems to be on the small side 25" tall 30" wide in the front, 25" at the back and 22" deep. Any ideas on what to do with it ?
