Looking for a way to reduce your heating bills? Wood boilers from Alternate Heating Systems are engineered to deliver powerful, efficient, and environmentally-friendly heat for both residential and commercial spaces[^1]. Manufactured in Pennsylvania since 1981, these systems combine rugged design with advanced combustion technology to offer one of the most reliable wood heating solutions available today.
Why Choose Wood Boilers?
Wood boilers harness the natural energy stored in wood to provide heat, without the volatility of fluctuating fuel prices. Unlike traditional fireplaces or basic wood stoves, these systems are engineered to burn cleaner, hotter, and more efficiently. Alternate Heating Systems takes this even further with their innovative Wood Gun line.
Gasification: The Heart of Efficient Wood Boilers
At the core of Alternate Heating Systems’ wood boilers is wood gasification technology, which burns both the wood and its gases for maximum energy extraction. This results in up to 85% efficiency, meaning less fuel is needed to heat your home or facility[^2]. Our wood gasification boilers use 2/3 less wood than a conventional wood boiler.
The true downdraft design of these wood boilers pulls flames and gases downward into a high-temperature combustion chamber, ensuring complete and clean combustion[^2]. This also minimizes creosote buildup and significantly reduces emissions.
Long-Lasting Wood Boilers Built with Stainless Steel
One of the most important aspects of choosing a wood boiler is longevity. The Wood Gun series stands out with fireboxes and heat exchangers made from ¼” thick Type 304 stainless steel (on models E100 through E250)[^3]. Larger models (E500 and E1000) feature stainless steel in all critical, corrosion-prone areas[^3]. All of this is backed by an industry-leading 20-year warranty, offering unmatched peace of mind.
Maximum Heat Transfer with the Swirl Chamber
Unlike many conventional wood boilers, the Wood Gun features a patented Swirl Chamber that maximizes heat extraction while minimizing maintenance[^4]. Exhaust gases start at over 2,000°F and exit the system at just 350°F—proof of the chamber’s efficiency. Even better, the Swirl Chamber is nearly self-cleaning, requiring minimal user upkeep.
Flexible Heating with Dual-Fuel Capability
If you’re not always home to load your wood boiler, no problem. Alternate Heating Systems offers optional dual-fuel capability, allowing your boiler to automatically switch to oil, propane, or natural gas when needed[^5]. That means you get consistent heat—no matter what.
