Abstract
A wood-burning boiler is provided, comprising a combustion chamber having a first air intake, and being adapted for holding combustible wood. An exhaust chamber is fluidly coupled to the combustion chamber, and is adapted to receive burnt gases from the combustion chamber. A preheat chamber is included, having a second air intake, and the preheat chamber is fluidly coupled to the combustion chamber and is conductively proximate to the exhaust chamber such that the burnt gases in the exhaust chamber heat the air within the preheat chamber prior to the air in the preheat chamber entering the combustion chamber. The boiler also includes a water jacket conductively proximate the combustion chamber.
