TALKED TO THE OWNER OF THE KUUMA FACTORY ABOUT HIS UNITS. SOUNDED GOOD TO ME. ALSO HAVE READ THE POSTS ON THE CADDY. ALSO LOOKS GOOD. AM STUMPED! ARE THERE OTHERS I SHOULD CONSIDER? BACKGROUND: LOG CABIN IN N. KY. NOT VERY WELL INSULATED,BUT NOT TERRIBLE EITHER. ABOUT 1200 SQ. FT. ON THE MAIN LEVEL WITH A LOFT ABOVE-TOTAL ABOUT 18 FT. CEILING. FULL BASEMENT(UNFIN) BELOW.THE YUKON IS IN THE BASEMENT. LEAKY,BURNS A LOT OF WOOD AND AS A RESULT IS NOT VERY EFFICIENT. TIME FOR AN UPDATED UNIT. WOOD: HAVE MANY CORDS OF PRIME HARDWOOD-ASH,WH. AND RED OAK,HICKORY-NO JUNK. STUFF I BURN IS MIN OF 2 YRS. C/S/S/ AND OUT OF THE WEATHER. NOTHING IS BURNED OVER 18%. WANT SOMETHING THAT CAN BE EASILY ADAPTED TO EXISTING DUCTWORK. ANY IDEAS?
