Apparatus and method of automatically regulating intake of air into heating unit

This invention relates to a novel apparatus and method for automatically and dynamically regulating the intake of air into the combustion chamber of a heating unit such as a wood burning stove, furnace, or fireplace to ensure even and efficient burning of fuel. More particularly, this invention pertains to a method and apparatus that uses negative gas pressure in the heating unit's flue, and no additional temperature or pressure sensors, to automatically and dynamically control a damper regulating intake of air into the combustion chamber in inverse relation to changes in negative flue gas pressure. This method and apparatus are especially useful in combination with a heating unit having two combustion chambers, one chamber for combustion of solid fuel and a second chamber for further combustion of exhaust gases and other byproducts from combustion in the first chamber. The two-stage combustion in a dual chamber heating unit is an especially dynamic situation where traditional static controls are not very effective.
