In which type of heating system do emissions pass through a specific material to facilitate combustion?

A catalytic stove employs a specific catalytic material, usually made of materials like platinum or palladium, to support and enhance combustion. In this type of heating system, the emissions pass through the catalyst as they exit the combustion chamber. The catalyst accelerates the chemical reaction that occurs during the combustion process, leading to a more complete burn of the fuel, which in turn reduces the production of harmful byproducts such as smoke and unburned hydrocarbons. This technology is designed to maximize efficiency and lower emissions, making catalytic stoves an environmentally friendly heating option.

In contrast, a gas furnace burns natural gas or propane for heating without the need for a special catalytic process. A wood burner typically involves burning wood directly, with emissions not passing through a catalytic medium. An electric heater does not produce combustion emissions since it generates heat through electrical resistance.
