Question: Is this stove U L certified?
Document: We have used this stove in a 2200 sq ft central MN home for about 2/3 of a heating season and are happy with it.I too rec'd the T-stat and fan options.
This is a quality stove that needs a outside combustion air fire box port. Optional fan with thermostat recommended. Using in 2000+ sf cabin and it has great aesthetics with excellent burn time.
It is about 500 lbs so get a good 2 wheeler with straps or 2 husky men to move it. You can easily pay about $2000 for a similar quality stove. It looks real nice too although its not in the catagory of a "decorator appliance". It can put out a lot of heat and hold a lot of fuel.
etc.). Soft woods would be OK for less demanding needs (less hours of less output). Getting up midevening or relighting on chilly mornings gets to be a pain after a few years.Its a XLG stove and I wouldn't put it into a situation where it heats less than 1500 sq ft. It would overheat it or smolder too much at the min. setting.I wish the design had a T-stat bimetal inlet damper feature. It does not and is not available.
THIS STOVE IS EASY TO START A FIRE IN, QUICKLY HEATS UP AND HOLDS ENOUGH WOOD TO LAST ALL NIGHT. OTHERS HAVE SAID THE DOOR NEEDS TO BE LEFT CRACKED OPEN UP TO A HALF HOUR TO GET WOOD STARTED, BUT IF YOU KINDLE CORRECTLY, IT CAN BE SHUT WITHIN A MINUTE OR TWO. IT IS WELL MADE OF HEAVY DUTY MATERIAL AND LOOKS GOOD IN OUR LIVING ROOM. I DID REPLACE THE PAINTED WOOD AIR DAMPER HANDLE WITH A CUSTOMIZED WALNUT HANDLE ENGRAVED WITH OUR LAST NAME.
Answer: no
