The E180 puts out 180,000 BTU/hr and can cover up to 5,000 square feet. A third-party testing lab evaluated it at more than 80% efficiency.
The E180 can be utilized with any heating system (water-based, steam, forced-air). The Wood Gun line has been tested and proven for more than 35 years! It was designed to lessen the work involved that is found in a typical wood stove…
For residential wood boilers, see our Super E210.
The firebox of every Wood Gun™ can accommodate wood sizes varying from uncut wood to complete rounds of 10″. Generally, the huge firebox requires only loading 2-3 times every day. 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 accessible front and rear inspection doors and the included ash rake and scoop make cleaning quick and practical.

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.
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.
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.
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 running which would blow the remaining heat out through the flue.
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.
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.
The E180 is capable of producing 160,000 BTU/hr when burning 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.
ASME Certification
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.
Low Pressure Steam
The Honeywell Aquastasts are switched out for Honeywell PressureTrolls and two Low Water Cutoffs are included. An automatic water fill valve and Steam Relief-Valve are also included. In some models, the vessel is changed slightly to allow for a larger steam shelf. The Wood Gun can produce steam up to 15 psi. To know what size steam boiler you need, first, figure the amount of BTU/hr needed for your home, then add 20% to the total. This extra 20% is only needed to create the initial head of steam.
Note: only available on Carbon Steel boilers.
Variable Speed Induction Fan
This enables the BTU output to be easily changed. This is accomplished by upgrading the 1-phase motor to a 3-phase motor and controlling the motor with a Variable Frequency Drive.
Canister Pool Heater
Heat your pool with wood! Available in either Carbon Steel or Stainless Steel. This is a separate canister from the vessel.
Automatic Feed
The Wood Gun™ series can be ordered with the ability to automatically feed itself wood particle fuels, such as sawdust, wood chips, shaving, pellets, etc. The Wood Gun™ auto-feed system loads the fuel into the firebox from the top. Only slight reconfiguration is required to still burn logwood in the firebox! This option comes with a photo-eye sensor, which controls when more fuel is needed, and an upgraded control center, which allows the user to easily control the entire system in one location. Touchscreen controls are available as well.
Additional Required Pieces:
- Rotary Airlock – Rubber blades or machined stainless steel.
- Fuel-Valve – acts as a second airlock, available in stainless steel.
- Transition Tubes – available in stainless steel – connects the boiler to Airlock, Fuel-Valve, and Auger
- Auger – available in nearly any diameter (4″, 6″, 8″, 10″) and any length
- Diverter Bricks
- Secondary Air Brick with cover
