The E100 model is available in carbon steel and stainless steel. It puts out 100,000btu/hr and can heat up to 3,000 square feet. It is the smallest model in the Wood Gun series and is rated at over 80% efficient.
The E100 can be used with any heating application (water-based, steam, forced-air). It was built to reduce the labor involved that is found in a typical wood stove.
For residential wood boilers, see our Super E110.
The E100’s firebox can accommodate wood sizes ranging from unsplit logs to full rounds up to 10″. Typically, the large firebox needs only be loaded 2-3 times daily. The Wood Gun will handle wood of relatively high moisture content, as high as 35% moisture, freeing you from curing a 12–18-month supply of wood (30% moisture or less is preferred). Unlike European-style gasifiers, the Wood Gun excels on full rounds.
Weekly cleaning allows for optimal performance. The easy-access front and rear inspection doors, along with the included ash scoop and rake, make cleaning fast and convenient.
A high-velocity draft fan moves air through the wood, allowing for an easy cold startup. After the gasification process begins, this air movement produces intense flames and very high temperatures in the gasification tunnel. In turn, the air flows through the heat exchanger, cleaning it as it passes through.

Domestic Coil
This Domestic Coil features a 100° F rise at 5 gallons per minute, 50° water inlet temperature, and 65 PSI water pressure. It is threaded into a 4 IN NPT threaded fitting provided on the boiler for this purpose.Cycle Timer
This feature adds a timer that triggers the boiler to run for 10 minutes every 2 hours, even if there is no call for heat. This maintains an internal temperature above the kindling point, reducing the need to manually relight the unit during periods of low demand.Smoke Exhaust Hood
The Smoke Exhaust Hood mounts over the loading door, capturing any smoke that may escape during the fuel-loading process. This smoke is then vented directly to the outside through a separate vent. When tolerance for smoke is low, the smoke exhaust hood is essential.Low Temperature Shutdown
If all the fuel has been consumed in your boiler, the Low Temperature Shutdown Feature will prevent the boiler from attempting to fire. This keeps the draft fan from running which would blow the remaining heat out through the flue.Oil/Propane/Natural Gas Backup
The Wood Gun wood boiler can be fitted with a backup fuel option. This requires a dedicated firing tube that must be built in during manufacturing.
The E100 is capable of producing 80,000 BTU/hr when running on oil, propane, or natural gas.
Automatic/Manual Switching
For #2 fuel oil, the oil backup can function in an automatic switch-over scenario, with fuel oil taking over when the boiler has exhausted its wood fuel. For other fuels, such as natural gas or propane, switch-over is manual only.
