I have an old, 3000 sq ft home with an oil furnace and steam radiators. We are interested in converting the radiators into hot water units (they have two pipes- supply and return)and heating with an indoor wood boiler (garage or basement). I would like to convert the first floor to radiant (floor joists are open in cellar). Friend has a Tarm, but I also like the looks of the Grenwood. Is it possible to convert the steam system to run with a wood furnace?
