Set and forget — electronic ignition eliminates matches and messy starter mixes; allows ‘set and forget’ thermostat setting.

Saves fuel with auto shut-off after periods of ‘no heat required’. Automatically re-ignites when heat is called for.

Thuroheat™ Delivers Maximum Heat
Heat your WHOLE home. Thuroheat™ Chamber features an exclusive multi-stage airflow design that delivers more usable heat to your home than furnaces boasting higher BTUs. Endurance draws cold air, warming it across the preheat manifold, then through a high-performance heat exchanger with 18 ft. of stainless steel heating tubes. The result is more thorough heat transfer, higher output at the plenum and minimal waste heat at the exhaust.

Cyclean™ Technology Minimizes Cleaning
Most furnaces that heat with corn require daily shut down and messy clinker removal. Not the Endurance. The patent-pending Cyclean™ technology is a self-cleaning fire pot that automatically discharges a light ash wafer while maintaining the flame, assuring a continuous, uninterrupted fire. You simply empty the ash pan as required, which averages once a week.

Smaller Foot Print, Bigger Output
Endurance requires only 5 sq. ft.; easier to install — with greater heat output that units twice as large.

99% Combustion Efficiency
Positive auger feed and complete combustion means you’ll burn 99% of your fuel, with virtually no waste, for even greater savings.

Stainless Steel Burner Pot and Heat Exchanger
These critical components must be engineered to withstand continual exposure to high temperature and hot ash. Endurance features a rugged stainless steel burn pot and heat exchanger tubes for years of dependable performance — we invite comparison.

Larger Hopper
Holds 112 pounds for longer burn times with fewer loads.

Attractive Cabinet
Endurance is a handsome addition to your living area — the modern cabinet features radius corners and a powder coat finish. The large front door glass offers an enjoyable and practical view of the fire.

Fully Programmable Thermostat
Set your personal preferences in the easy to use control panel; a wide range of settings helps keep your home more comfortable. Choose manual or thermostat mode.
