All that wood burning info you may want to find is at.www.woodheat.org. I just came inside, 25 degrees in Nov...and thought I wood look up woodfiredboilers. This was the site I spent some time at. Good info, seemed up to date, not to much bashing. Decided to wait on a boiler and just stick with the wood stoves. Plenty of info for those there too. Be safe with wood...educate yourself... stay warm and cozy.
