Commercial Wood Boilers E100

The E100 model is available in both carbon steel and stainless steel. It puts out 100,000btu/hr and will heat up to 3,000 square feet. It is the smallest model in the Wood Gun series, 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…



The Wood Gun™ wood gasification boiler by Alternate Heating Systems is perhaps the most efficient wood-burning device on the market today. This uncompromising multifuel system is ideal for any residential application where conventional log wood is used as fuel. The AHS Wood Gun™ E100 is well suited for homes up to 3000 square feet, subject to building design and construction.



The firebox of each Wood Gun™ can accommodate wood sizes ranging from unsplit logs to full rounds up to 10?. Typically, the large firebox need 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 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.



Wood Gun™ boilers can be fitted with either fuel oil, natural gas, or LP gas backup. The Riello fuel oil burner will allow you the option of automatic backup. This allows you to save money by burning a renewable fuel source and the convenience of burning oil. The oil backup system is rated over 84% efficient. With an efficiency rating that rivals top-of-the-line oil units, you cannot go wrong.



STAINLESS STEEL CONSTRUCTION

Wood Gun boilers use ¼” thick Type 304 stainless steel in the construction of the firebox, heat exchanger, and door frames. We use Type 304 stainless steel for its unsurpassed quality and longevity. Our stainless-steel boilers show no signs of deterioration, even after well over 20 years of service.



SMOKE

The Wood Gun™ wood gasification boiler, when installed, maintained, and operated properly, produces no visible smoke, and creosote formation in the chimney is prevented.



STACK TEMPERATURE

Exhaust stack temperature is one indicator of transfer efficiency. During combustion, temperatures of around 2000° Fahrenheit can be obtained. Amazingly, our exhaust stack temperature ranges from about 260-300° Fahrenheit. This stack temperature is unheard of in the industry. The Alternate Heating Systems Wood Gun™ is truly the pinnacle of wood-fueled heating devices!



HOW IT WORKS

Wood gas is produced by applying high heat to wood is a process called pyrolysis. The wood gas is drawn through the bottom of the firebox and into our uniquely designed refractory by an induction fan. The gases are combined with oxygen and combusted in the refractory. The super-heated gases pass through the interconnected refractory tunnels and into our uniquely designed swirl chamber. This is where the bulk of heat exchange takes place. Above the heat exchanger, the superheated refractory continues to gasify the wood remaining in the firebox. After combustion, the residual ash is combined with high-velocity airflow to scrub the heat exchanger preventing any build-up. This process leads to unparalleled consistency in heat exchange. Most ash exits the unit and is collected in the cyclone ash separator for fast and easy removal.



The Wood Gun™ cycles on and off much like an oil or gas-fired boiler. During the off-cycle, fuel is not consumed because oxygen is not present in the combustion chamber. With the large superheated refractory mass, re-ignition of the fuel occurs automatically when a drop in water temperature signals the need for heat. Automatic re-ignition can take place as long as 4 hours or more after the last firing cycle depending on boiler size.



During the off-cycle, wood gas inside the firebox condenses on the inner walls forming a solid that will eventually fall off. This combines with the remaining fuel, adding energy that in many other boilers goes up the chimney
