Abstract
Heating devices and methods for mitigating heating device pollution are generally described. In an example embodiment, a heating device includes a primary combustion chamber for combustion of a fuel. A first and a second secondary combustion chamber are in fluid communication with the primary combustion chamber for receiving an exhaust flow of combustion products from the primary combustion chamber and are configured for combustion of one or more combustion products received from the primary combustion chamber. The first and second secondary combustion chambers may provide parallel fluid paths from the primary combustion chamber. A secondary combustion selector is provided for selectively allowing the exhaust flow through the first and second secondary combustion chambers.
