Well after all of your help and questions being answered I decided to to go with a Kumma Vaporfire 200. Expectations were high and they were by far exceeded. I ran separate ductwork from the Vaporfire to the existing registers in my home. I am currently burning less then ideal wood and getting 8hr burn times I would expect them to go to 10-11 hours maybe more when I start burning locust and oak. My house is 2200sft and it was 31deg last night - woke up to a 73 deg house!! with a bed of coals. Best of all - NO SMOKE. Granted the first 5 - 10 min a small amount of light smoke can be seen coming from the chimney but it quickly turns to vapor and stays that way usually even through reloads. Very little ash. I should have went with the glass door though. Sometimes I just cant help myself from opening the door to see whats going on in there. I might get it because I was told that opening the door during a burn decreases the burn time from the cooling of the fire chamber. I will keep you guys posted. Feel free to ask any question. Overall excellent product built like a tank and absolutely great people to deal with.
