Drying Chamber
In the Wood Doctor Converter, heat that rises is trapped in the Drying Chamber where it dries out the wood and eventually transfers to the water exchanger... no heat or emissions escape out the flue.

Initial Firebox
This is the chamber where the actual fire occurs. In the off cycle the wood burns with no open flame and the heat and creosote smoke rise upwards into the Drying Chamber. In the on cycle the flames are pulled down through the coals creating a very efficient burn. The fire is Upside down. Dry wood is automatically fed as required.

Hopper
The wood is first placed on a ledge and then tipped into the hopper. This prevents hang-ups. The hopper holds wood up to 26 inches with a total capacity of over 11 cubic feet.

Final Combustion Chamber
This is a separate insulated ceramic chamber underneath the Firebox. The heated air in the firebox, including all smoke gas and creosote, is drawn downwards through the hot bed of coals and into the Final Combustion Chamber. Injection Air is added from above the coals and also pulled through the coals. The extreme heat (up to 2000°) ignites all gases including smoke and creosote. These gases, which would otherwise be exited out the flue, are used as fuel giving nearly 100% burn efficiency. You can expect the Converter to use up to 50% less wood than most wood stoves on the market.Water Temperature Simply turn a dial and the Converter matches the heat produced to the heat required. Big buildings or small - one size furnace does it all without excess fuel consumption.

Injection Air
A fire needs air to continue burning. The Converter features Air Injection. When the water temperature drops, air is injected into the firebox in measured quantities in just the right location - much like a blacksmith's forge. The fire burns extremely hot. Upon reaching the preset temperature, the air injection reduces and allows the fire to burn without open flame. During this stage, the heat produced is transferred to the Drying Chamber.
