What makes a gasification Outdoor wood furnaces so unique?

What makes a gasification Outdoor wood furnaces so unique? Barrett Enterprises, Inc, is all about Green Products that reduce use on fossil fuels while being environmentally friendly. These Gasification outdoor wood furnaces create less smoke, use less wood while creating more heat. Gasification is a process for burning wood where the gases from the wood are burned at very high temperatures. The term gasifying means that the wood is being superheated and largely turned to wood gas to be burnt. Traditional wood furnaces do not reach high enough temperature to achieve this. Gasification is achieved by drawing the wood gases off using an induction fan and then burning the gases underneath the wood so that much more complete combustion occurs. Downdraft produces extreme heat up to 2000 degrees igniting all gases including smoke and creosote therefore giving almost 100% efficiency!

These units are so clean burning that the Federal Government has qualified them for the Energy Tax Credit.


It will give you:

  • Lower Emissions - Less Smoke !
  • Less wood consumed Burns about 1/2 as much as other outdoor wood furnaces
  • Longer Burn times A true 18 - 24 hour burn
  • Less wood consumed About 50% less wood than other OWHH
  • Higher Efficiency Almost 100% combustion
  • 3/5 inch boiler plate with 20 year pro rated
  • warranty
  • Will produce very steady heat
  • Comes with an ash pan for easy clean out
  • Heats homes, business, radiant slabs, hot water, greenhouses, hot air, hooks to existing systems or for new construction.

If you live in a state that does not currently require an EPA Gasification furnace, the SHAVER models will give you the biggest bang for your buck!

What a great investment. No longer do I have to drag my wood into the basement. No more running up and down the steps to load a wood furnace 4 times a day. No more smoke in the house. No more house that seems either too hot or cold. My new wood furnace sits out beside my wood shed which eleminates handling the wood as often, plus I do not need to cut my peices of wood as small anymore since I can take up to a 4 foot peice. I load the stove in the morning on the way to work, and in the evening after dinner.
