G-Class Wood Furnaces

G-Class is all about making wood burning as clean, simple and easy as possible while eliminating your high heating bills. To accomplish this, the G-Class is packed with an impressive array of features which together deliver unmatched product value. You will love how easy the G-Class is to operate and be amazed at how much less wood you will burn when compared to older outdoor wood furnace technology. G-Class takes it to a whole new level.

  • Efficient – The combustion chamber can reach temperatures up to 2000°F because the perfect amount of oxygen, fuel, and high temperatures enter inside the chamber. This creates an extremely high temperature vortex of fire which fully burns every ounce of wood for an efficiency rating of 99.5%! Which means every possible BTU of energy is extracted from the fuel (wood) and smoke is converted into heat. When an older style outdoor furnace is replaced by a G-Class furnace, the saving on wood consumption is as much as 60%!

  • Easy to clean – Heat exchangers within wood furnaces get coated with dust over periods of time and have to be cleaned regularly to maintain their efficiency. All G-Class products include the EASY SWEEP SYSTEM. This allows the heat exchanger to be cleaned daily in as little as 5 seconds!

  • Safe to use – Whenever the fire chamber door is opened, the suction fan and a channel built into the top of the fire chamber work in tandem to extract any smoke to ensure your comfort and safety during loading. This is an absolute must for indoor installations.
