I have an old 1982 russo that has a nice fireview window with blower but no secondary burn technology at all that I am currently using and just picked up what appears to be a hearthstone hii. I might just consider cleaning both up and fresh paint , selling, and getting something more energy efficient. I also have an older harmon pellet stove I got in trade with all wall piping but not thermostatically controlled. I should stop collecting junk and just buy something new, my wife prob wouldn't oppose. lol. I use the woodstove in the basement of a 1500 sq ft very poorly insulated Cape with a fieldstone foundation and have a Castille pellet insert in my old firebreathing dragon of a fireplace. I am new to the forum but have been getting some good information for years from here. Thanks to all.
