I have two corn stoves in my house, and they work great! I got both of them from Pinnacle Corn Stoves this past winter. www.pinnaclecornstoves.com I installed the Ruby model myself in the fireplace in my den, and it only took about 45 minutes. Piece of cake. The Emerald model heats my workshop cheaply and efficiently. When I had a question about the installion, I called them up, and they were very friendly, knowledgeable and helpful. I recommend them highly!!!
