Hi SM, the wood stoves and inserts are fantastic. Except for the sec burn baffle, very much like PE and Regency. The SS sec tubes are solid performers, I've had the 1700 FS for the past 4 years, its the best burning stove I've had. That's against a Jotul Oslo, Quad 3100, and HS Phoenix, all outstanding burners. Easy to light and run, typical steel stove and great pricing too. Talk to Phil at Russo, Enviro is the best kept wood stove secret around. I'd highly suggest carrying them, we sell them ourselves down here. Supposedly the 2100 is being redesigned, still has the brick baffle in the top and center tube like Napoleon and Energy King at one time had. The Boston is a pretty insert, but the cast mounting frame was close to the blower (mounted vertical on LSF) and would make contact if not just right, we handled prob with gasket in between. The Kodiaks are excellent pricepoints, the 1200 is a solid 1500sqft heater, the 1700 solid 2k plus heater. Enviro (like many other mfrs) went nuts on their ratings in sq ft for the cabello, its the same engine as the others. It was meant to compete against VC Montpelier and Quad's Voyageur (flush mount inserts) the depth is the limitation if there is one. Hope this helps Good luck.
