First off, I want to thank the many who regularly contribute to these boards. I've lurked for a while now and learned a lot, and been entertained more. After much thought I think I'm going to install a wood furnace in my basement. I have a RSF see through wood fireplace that is absolutely beautiful, the wife loves it, and we burn everyday (winter) when we're home; but it is not super efficient. I've been trying to figure which wood furnace to purchase and have kinda narrowed down the choice to three different furnaces. BUT NOW, I noticed Blaze King is advertising a new cat wood furnace called the "APEX CBT" Any one hear anything about this neat looking wood burner? http://www.blazeking.com/furnaces-heaters.html Herbster PS I'm heating a 2600 sq ft house, air tight (air to air exchanger), well insulated, in central Wisconsin. Been using wood on and off since college when I lived up near Lake Superior. In 1977 we lived in a shack and heated it with a Sears "Wonder Wood."
