Outdoor woodburner

[MTW]

Here are some pictures of an outdoor hydronic woodburner that we designed and built.  This unit is not overly large externally, but weighs almost 2400 lbs before you add 300 gallons of water.  The unit is forced or natural draft with automatic controls.  We kept those simple so that if anyone of them went bad, a local hardware could get a replacement.  The firebox itself is 36" long, 30" wide, and 36" tall.  All together it can feed three 33gpm Grundfos pumps.
