How does the GT6000 work?

The new EPA Phase II Qualified GT-6000 Downdraft Gasification Wood Boiler is a 2-stage outdoor wood burning furnace that has a jet-engine inspired secondary burn chamber designed to heat the stage 1 burning wood exhaust to temperatures so high that unburned fuel left in the stage 1 exhaust is ignited for a 2nd stage of burning.  

Not wasting any heat, the stage 2 exhaust is then sent up through 2 sets of six pipes with butterfly diverters to again spin the hot exhaust gases. The heat exchanger pipes are surrounded by a flow of water from the circulating pump. This pulls even more heat into the water finishing the burning & heating process to make the GT Series the most efficient, reliable & cost effective gasification outdoor wood boiler you can find!

The wood gasification process has made heating with wood more efficient. If you go to our youtube site you will find several videos that will explain the wood gasification process and show information on the high efficiency wood boilers that we sell.
