The E155 OBE (Outdoor) model is an outdoor boiler unit. It is similar to the other E155 Models, however, it includes a custom-built heat shield cover to help reduce heat loss to the outdoors.
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).
Note: While our outdoor models produces the same BTU/hr as our indoor Wood Gun units, they will heat less square footage due to heat lost naturally to the outdoors.

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.
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.
