Does anyone have experience with one of these boilers burning only wood? I'm having my faulty TL300 replaced free of charge from Harman and would like to go with a wood burning boiler this time around. I have an 1150sq ft. ranch house on a full basement. The basement will be 2/3 finished with the other 1/3 the boiler/water tank/etc room. The house was built in 1994 so insulation should be decent, although I do not know what R value it is. I currenlty have NG HWBB that I would tie a boiler in to. My biggest concerns with the Harmans is the short burn times it seems most have with burning wood only. If its going to burn out of wood through the night or while Im at work and the gas kicks on, its not of much use to me. Not to mention the creosote buildup from idling. Please don't say to burn coal. I get free wood and am going to stick with wood only. I know the gassifiers are much better option, but also much more $$$, and I don't have room for storage. So with that said, is the Harman a wise choice, or should I just save and go with a gassifier without storage? Can someone suggest one that is reasonably priced? Thanks for any help.
