so closing on the new house Monday, and still have not decided on which furnace to go with. My choices have actually went up not down.... although the kuuma is not completely out of the running my main fear is it won’t keep up on the very cold nights and weeks we get here. Central Ohio with a well insulated 3000 sq ft home not counting basement. Next is the max caddy which I’m leaning more toward since today I found a deal at a dealer for $3650 out the door with all the accessories needed to run. However with this stove same issue minus price is I’m affraid it won’t keep up on extreme cold weeks. Last option is the ds stove kozy king 400, good price at 3350 and will put out more than enough heat and still has an efficient rating of just over 85%. However I feel this stove will use more wood than the other two and not quite the set it and forget it like the other two. Anyone have experience with the kozy king? Maybe compared heat output to the maxcaddy? Also one final question is the max caddy has a rating called maximum input btu of around 400k btu and another btu rating of only around 67k can any one break this down for me? Also the Kozy king has a 205k btu where the kuuma has only a 30-40k btu rating can someone break these numbers down?
