This chamber has small vents at the beginning where the stage 1 exhaust comes through from the burning wood above. The exhaust is ‘turbo boosted’at this point by a forced air blower. This air boosts the re-ignition for the stage 2 burn, supplying much needed oxygen to the fire forcing it to curl into itself which increases the heat and burn efficiency. 

The firebrick reaches a 'hyper-heated' condition causing the fire to burn even hotter. This is where gasification occurs. The temperatures inside the DSBC can reach 2000 F or more. Wood normally burns at 800-900F! The stage 2 exhaust is then forced to travel in a spinning motion through refractor channels. This circulation helps the refractory to evenly transfer the heat to the steel, then to the water. For maximum heat transfer, the firebricks are cemented to the steel. When researching competitor's units, check to see if they utilize this technology.

The stage 2 exhaust gases now run through a ceramic honeycomb catalyst filter. Using this catalyst filter increases the stage 2 gasification exhaust heat from 500F-800F up to 1500F which further burns particulates and any usable molecules. Again, when researching competitor's units, check to see if this technology is used. Not wasting any heat, the stage 3 exhaust is then sent up through six pipes that 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, cost effective wood boiler you can find!

Not wasting any heat, the stage 3 exhaust is then sent up through six heat exchanger tubes that 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 gasification furnace the most efficient, cost effective outdoor wood furnace you can find!

 Go Green & Heat For Less This Winter

Burning wood for home heating is a great way to reduce your carbon foot print. Wood is considered carbon neutral by some scientists. Carbon released during combustion of wood is in the active carbon cycle. The carbon that trees take in from the atmosphere is released the same way when wood is burnt as it is when wood decomposes. Burning wood is almost totally carbon neutral. Your only carbon foot print is from the cutting and transportation of the wood you are burning.
