Four Reasons to Choose
a HeatMasterss Furnace

Easy to Use

Cruise Control for Your Boiler

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.

Stay Clean & Safe While Loading

The Smokeless Loading Handle turns on the fan and vacuums the smoke up the chimney and away from you while loading.

Simplified Cleaning & Maintenance

No brushes, scrapers, chains or tools! The EZ Clean Handle makes quick and easy work of cleaning the heat exchange tubes.

Stay Out of the Weather with Indoor Installation

Most furnaces can only be installed outdoors. The G Series is also UL listed and CSA approved for installation in a garage, shop or other outbuilding.

Optimal performance in all places and at all times.

Saves You Money

Greater Heating Capacity & Longer Burn Times

A larger firebox gives 20-40% more heatingcapacity for the same price or much longer burn times.

Extend Your Heating Season to Reduce Energy Costs

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.

Save Time, Labor & Money

Our patented Tornado Combustion Chamber (Patent Pending) provides a cleaner, more complete combustion, reducing fuel costs and your time and effort preparing the fuel, loading. and cleaning the furnace.

Achieve Energy Independence

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.

Built to Last

Designed with a Purpose

Our in-house team of expert engineers design every aspect of our boilers 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.

Titanium Enhanced 409 Stainless Steel
  • Resists Corrosion
  • Withstands Higher Continuous Temperatures
  • Transfers More Heat
  • Doesn’t Crack or Warp
Best-In-Industry Lifetime Limited Warranty

We back each furnace with our best-in-industry Lifetime Limited Warranty, twice as long as the leading mild steel competitor.

Rigorous Testing and Quality Control

Our ISO 9001 Certified Manufacturing Processes, extensive field testing and ongoing quality control checks mean world class consistency in every furnace we build.

Home Monitoring

Check on your furnace from any device on your home network.

Smokeless Loading Handle

Vents heat, flame and smoke out of the chimney while loading. Approved for indoor installations.

EZ Clean Handle

Cleans heat exchange tubes quickly and easily. No brushes or tools required.

Ultra Efficient Heat
Exchanger

Designed with the perfect size and quantity of heat exchange tubes to match the BTU output of the furnace. The spiral turbulators create a vortex which spins the hot exhaust causing friction with the tube walls. This results in greater, more efficient heat transfer to the water.

Insulated Hinged Rear Door

Intentional design creates convenient access to plumbing, fan motor and electrical components.

Recirculation Pump

Water temperature is kept consistent from top to bottom creating a greater heat storage capacity and shorter recovery times during periods of high heat demand.

New
Cruise Control for Your Furnace

Oxygen and fuel (smoke) are precisely mixed to achieve the desired BTU output while maximizing performance and reducing emissions in all conditions.

New
Large Capacity Firebox

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.

New
Tornado Combustion Chamber

Patent Pending
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.

New
Thermal Resistant Foam
Board Insulation

The water-resistant board with reflective aluminum backing creates an air gap and higher R Value which increases as the furnace temperature rises.
