Wood Gun High Efficiency Gasification Wood Boiler.
The Wood Gun wood gasification boiler by Alternate Heating Systems utilizes the most advanced technology in wood burning and is perhaps the most efficient wood burning device on the market today. This uncompromising multifuel system is ideal for any residential application where wood or wood by-products are used as fuel. The AHS Wood Gun is available in residential sizes ranging from 100,000 to 250,000 BTU’s and commercial sizes up to 1,000,000 BTU.

Features:
  • Automatic cycling on and off in response to heating or hot water demand.
  • Domestic hot water coil provides abundant quantities of hot water.
  • Exceptionally safe and clean burning. The use of dense refractory material cast into specific shapes causes complete combustion to occur at temperatures of up to 2000° F.
  • When operated properly in the gasification mode, visible smoke is eliminated and creosote formation inside the chimney is prevented.
  • The large cyclone separator removes most of the fly ash resulting in very 
  • low emission.
  • Spontaneous re-ignition of the wood will occur after an off period of 2-4 hours
  • Re-ignition is dependent on the refractory temperatures.
  • Wood Gun readily adapts to new or existing hot air systems through the use of a heat convection coil.20 Year Warranty
  • The design maintains all heated walls at the same temperature using a "water wall". This constant temperature eliminates stress fractures caused by differences in temperature between components of the boiler thus increasing it's life. In addition, this design produces greater efficiency because heat that is normally lost through a drywall is captured in the water wall.

Stainless Steel Construction

All Wood Gun boilers use 1/4" thick Type 304 stainless steel in the construction of the firebox and door frames. We use Type 304 stainless steel for its unsurpassed quality and longevity. Some of our stainless steel boilers have been in service for over 28 years and they show virtually no signs of deterioration. It is the combination of the Wood Gun's stainless steel construction and the ability to utilize an off cycle that eliminates the need to use thermal storage in heating applications that utilize the Wood Gun.

Wood Gun Residential or Commercial?

The Wood Gun E250 represents our crossover unit between the residential and commercial Wood Gun boiler lines. Commercial Wood Guns are characterized by larger capacities, heavier door refractory, belt-driven induction fans, and default features (dual air inlets, top fuel feed port and others) not found on our residential units. It is best to size a unit based on heat load, with the goal of having sufficient load on the boiler to keep good refractory temperatures.
