Explore the B SeriesIntroducing our latest HeatMasterss outdoor wood boiler that will revolutionize the way you heat your home.
Through the power of gasification, and using wood already available to you, this is the best alternative heating method to eliminate your heating bill while providing long lasting heat.
Through meticulous research and stringent quality control procedures, we consistently hold the highest efficiency rating burning in real world conditions in the industry.
Gasification boilers require dry seasoned wood in order to efficiently utilize the gasification process. If you have access to firewood, you can benefit from the free heating and energy independence of our G series boiler.
Gasification boilers can use 30% to 50% less wood than a conventional style wood boiler. If you want to save time collecting, splitting, and loading wood, our G series boiler is right for you.
Cleans heat exchange tubes quickly and easily.
Oxygen and fuel (smoke) are precisely mixed to achieve the desired BTU output while maximizing performance and reducing emissions in all conditions.
The Smokeless Loading Handle turns on the fan and vacuums the smoke up the chimney and away from you while loading.
With a larger firebox, the G Series can heat a greater area while increasing time between loading the furnace. The full refractory floor provides consistent heat from corner to corner so the wood burns consistently and doesn’t “bridge” or hang up.
More efficient heat transfer to your water means few BTUs wasted and more heat for your home.
The longer chamber swirls the hot air in a tight spiral, meaning a more complete combustion resulting in higher efficiency, lower emissions and reduced fuel consumption.
Convenient access to plumbing, fan motor and electrical components.
Faster heat when you need it thanks to the recirculation pump that keeps the water temperature consistent from top to bottom and provides greater heat storage capacity.
Minimize heat loss thanks to closed cell spray foam that provides a seamless, dense insulation with an outstanding R-value, forming an effective air barrier.
Airflow to the top and bottom burn chambers is controlled independently with dual modulating dampers. An oxygen sensor optimizes the flow of air into the Tornado Combustion Chamber resulting in the cleanest and most efficient burn available.
Complete combustion is achieved as the oxygen and wood gasses swirl in tight spirals within the Tornado Combustion Chamber. Peak temperatures are maintained thanks to the mass of the refractory, and the chamber’s double pass allows enough time to burn all available fuel.
Heat exchange tubes with spiral turbulators transfer the maximum amount of heat to your water jacket, ensuring every available BTU can be used.
The G4000 is a great option for heating most family homes along with a garage or another small secondary outbuilding.
* Well-insulated building.

To choose the perfect size of furnace, you’ll need to know how many BTUs your buildings require.
For a helpful ballpark calculation, think about your insulation level
Now, add the total sq. ft. you are heating (house, garage, barn, etc.). Remember, for a basement, divide the sq ft. by half and add it to your total. So a 1,200 sq. ft. basement would actually only add 600 sq. ft. to your total.
Take control of your family’s budget and eliminate your heating bill with clean burning wood heat. Fossil fuel prices fluctuate but wood heat is consistently economical.
The G Series continues to be a leader in innovation with the highest efficiency ratings on the market, according to rigorous 3rd party testing. Using less wood means less loading, more heat!
A larger firebox gives 20-40% more heating capacity for the same price or much longer burn times.
Our innovative Tornado Combustion Chamber (Patent Pending) provides a cleaner, more complete combustion, reducing fuel costs and your time preparing and loading wood.
The new G Series can adjust its BTU output during periods of low heat demand while maintaining efficiency and reducing fuel requirements. Enjoy unlimited domestic hot water year-round or add a hot tub or pool.
The G Series is the only outdoor furnace that measures the exhaust and adjusts the air to guarantee the best real world performance and efficiency.
The Smokeless Loading Handle turns on the fan and vacuums the smoke up the chimney and away from you while loading.
No brushes, scrapers, chains or tools needed to clean your heat exchangers! Instead, the EZ Clean Handle makes quick and easy work of cleaning the heat exchange tubes.
Most furnaces can only be installed outdoors, but the G Series is UL listed and CSA approved for installation in a garage, shop, or other outbuildings.
Our in-house team of engineers design every aspect of our furnaces to achieve maximum performance and longevity in real-world applications. From the water jacket to the wiring, the G Series is fabricated to be the longest-lasting, most rugged furnace available.
We back each furnace with our best-in-industry Lifetime Limited Warranty so you can sleep easy knowing your investment is safe.
