My Jotul 3cb continues to almost, but not quite, comfortably heat all of my 1900 square ft. open-floor-plan two story. I'm happy with the stove and understand its limits, but I've gotten conflicting neighborly advice on how to heat best. My chimney is 25' straight shot double walled pipe. Some say install an in-flue damper because given the strong draft much too much heat is going up the chimney, others say the system is already well tuned and about efficient as it's going to be, don't mess with a good system and that any in-flue gadget will only encourage creosote and/or other problems. I had the chimney swept in the fall and the sweep said he found not a bit of creosote only soot. Like everyone I want to get the most heat out of my stove that I can. What do you think. I remain open to all ideas.
