Do not buy Regency I1150. Has not work properly from day one. Poorest designed wood stove insert I have ever experienced. Had this stove for about 18 months now. Instead of an enjoyable evening with a warm fire, I am vexed and irritated every time. I'd give it less than one star if I could. It cost so much that I cannot just throw it away and start over. But I might because this is the worst stove I have ever used. 1) Smoke pours out of the stove through the fan box and the sides when I light it. EVERY TIME. This did not happen with the old fireplace insert that this one replaced. Had the fireplace installer come out twice. He said the stove is installed properly and acknowledged he had seen this problem before with this stove. Other reviews on the web also mention this is a problem. He had the same problem when he tried to show me how to light the stove. Flue has a stainless steel liner. Said i could take out the smoke baffle and that might help. Will also void the warranty, so not helpful suggestion. 2) Stove burns super hot and fast. The damper has no noticeable effect. No way this stove burns for 8 hours because if you fill it up, it burns so hot you are worried about it cracking stove. Have to add a piece of wood every 30 min to keep a fire going without overheating. Yes, the door has been adjusted. 3) Fan makes a very LOUD noise - like the blades are hitting metal shield. We have to stuff a shim under the front to get it a little quiet - and then adjust the shim as eventually the VERY LOUD rattle is back. So we don't use the fan unless we are not in the room. What good is that? The point was to have a fire in the room we use the most.
