- 1/4″ Stainless Steel Construction
- OUTDOOR CAPABLE
- Qualified for 26% Tax Credit
This is the Super E210 Outdoor. This outdoor wood furnace can produce up to 170,000 BTU/hr and will heat up to 4,000 square feet. The SE210OD achieved 87% efficiency during testing without the use of thermal storage. Our stainless steel boiler vessels come with the industry’s best warranty!
The SE210OD is an outdoor wood gasification boiler that meets the newest EPA emission requirements. You can use this outdoor wood furnace with any heating application (water-based, steam, forced-air). The Wood Gun has been tried and true for over 40 years! We created the Super E210OD to reduce the labor involved in a typical wood stove…
The Super E210OD qualifies for at least two tax credit programs.
- The Federal Tax Credit of up to $2,000.
- The Efficiency Maine Rebate of up to another $6,000.
Introduction
The firebox of our outdoor wood boiler accommodates wood sizes ranging from unsplit logs to full rounds up to 10″. Typically, you only need to load the large firebox 2-3 times daily. The Super Wood Gun will handle wood of relatively high moisture content, as high as 29% moisture, freeing you from curing a 12–18-month wood supply. Unlike European-style wood gasifiers, our wood boiler excels on full rounds of firewood.
Weekly cleaning allows for optimal performance. The easy-access front bottom inspection door, along with the included ash rake, makes 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.



Stack Temperature
Exhaust stack temperature is one indicator of transfer efficiency. During combustion, temperatures reach around 2000° Fahrenheit. Amazingly, our exhaust stack temperature ranges from about 260-300° Fahrenheit, which is unheard of!
The Super E210OD has a second heat exchanger! The exhaust exits the swirl chamber and travels inside the insulated cabinet to the back of the boiler. We use this space to bring the combustion air around the exhaust. The second heat exchanger further cools the exhaust and preheats the combustion air. This unique design makes the Super E210 Outdoor the most efficient Wood Gun yet. We can achieve nearly 90% efficiency in this wood boiler.

Low Water Cutoff
A Low Water Cutoff senses the water level in the boiler’s vessel and will shut the unit down if the water level drops to an unsafe level. Available with automatic reset or manual reset.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.Variable Speed Induction Fan
This option comes free with every SE210. This enables the boiler to change the BTU output based on real-time needs. This is accomplished by upgrading the 1-phase motor to a 3-phase motor and controlling the motor with a Variable Frequency Drive.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.Canister Pool Heater
Heat your pool with wood! Available in either Carbon Steel or Stainless Steel. This is a separate canister from the vessel.Custom Engineering
At Alternate Heating Systems we have expert fabricators and engineers ready to tackle any design change! Whether it is a custom bin, moving the cyclone to the other side, an extra load door, water storage tank, or whatever you may need to fit your application.
