The E140 model is is available in both carbon steel and stainless steel, and can heat up to 4,000 square feet.
The Wood Gun line of boilers is the most fuel-efficient option on the market. While typical boilers waste two-thirds of your fuel’s energy potential, the wood gun captures and burns 66% more combustible matter, transforming it all into clean, consistent heat.
The Wood Gun was built to reduce the labor involved in standard maintenance…
Easily handling full logs of up to 10 inches in diameter, the Wood Gun spares you considerable wood-splitting work; with the ability to burn logs of up to 30% moisture, it cuts down on wood curing time; and, thanks to our signature Exhaust Scrubbing technology, the Wood Gun’s heat exchanger is self-cleaning—so the only cleaning you’ll have to do is weekly ash disposal.
The Wood Gun line can be used with any heating application (water-based, steam, forced-air).

Smoke Exhaust Hood
The Smoke Exhaust Hood mounts over the load 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 prevents the boiler from attempting to fire. This keeps the draft fan from blowing the remaining heat out through the flue.
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.
Note: A thermal storage option is a good idea for any wood boiler, but is especially important for boilers fitted with the cycle timer option.
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.
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.
The ASME Certification guarantees the steel grade and weld quality of the boiler water jacket. Each ASME Certified water jacket has been pressure tested to 60 PSI, and includes a 30 PSI release valve.
