I've used an outdoor wood "boiler" for years. Boiler is a misnomer because it heats water for the heat transfer rather than prooducing steam. I'm on my second one & they've improved greatly. I heat a woodworking shop (over 2000 sq.ft. w/13' ceilings). Northeren WI has cold that requires firing up from Oct thru May. I plan to expand to a green house that's heated soon.
 
Why I choose the Central Boiler brand: It's EPA approved, my woods in the back 40 is a renewable fuel source, shop scrap is a fuel source, safety over indoor flame, support from my salesman, & water test kit with optional treatment chemicals.
 
My experience: licensed boiler operator, industrial boiler operator for several years, & residential  boiler operation (both steam & hot water). I've burned wood half of my life as a primary or secondary heat source.
 
A better way IMHO is geothermal. I now use this for my residence. The underground gridwork is buried 6 or 7 feet beneath my garden. The energy input is electricity which runs the compressor, pumps & fan. We get heat, domestic hot water & air conditioning from one unit. It was twice the price of gas or oil furnaces initially. But I have used renewable geothermal energy for the heat/cool part of the equation for over 6 years with little fluctuation in my energy bills.
 
There are some biomass conversion products that I've seen prototypes of. They directly convert "waste" to heat, electricity or both. This could be the technology that makes cold climate green house a reality for wanabee winter gardeners in any climate.
