Plus !! First ever picture of my booth babe......otherwise known around the house as "management". The orange boiler is a Heizomat chip/pellet/sawdust/biomass burner and the red and white unit is a Windhager BioWin pellet boiler. The green part attached to the Heizomat is the burner and part laying separately is the feed auger that would go in the fuel bunker/bin. Both boilers feature fully automated fuel loading and ash removal. Just hook em up to the fuel source and let them run. I really like the rotary "valve" on the Heizomat burner. It helps size any abnormal pieces that get through the whole process before it plugs up the burner and it provides a 100% fail safe fire stop so a burn back could never get to the fuel bin. They make them all the way from about 100,000 btu up to 3.5MM and any of them will modulate down to 10% firing rate.
