Collection: Catalytic Combustors

Replacement Wood Stove Catalytic Combustors

SAVE MONEY: Using a Midwest Hearth combustor in your catalytic wood stove converts smoke from burning wood into heat. This produces more usable BTUs from your wood. Catalytic stoves can help you save up to 1/3 on wood costs. For families who buy 2 cords of wood a season, that could be $150 saved every year.

SAVE TIME: Enjoy longer (up to 8 hours longer) overnight burns without having to refuel your stove. Save time and sleep soundly, without the extra work to keep your stove loaded throughout the night.

CLEAN AIR: Particulates from burning wood is linked to cardiovascular, heart and respiratory diseases. Midwest Hearth catalytic combustors remove 70% of harmful wood stove emissions, keeping the air clean and your family healthy.

SAFETY: Catalytic combustors help prevent the buildup of creosote, so there’s a lower risk of house fires. Since 1990, the number of creosote-caused fires has decreased by 75% thanks to catalytic stoves.

MADE IN USA: Our catalytic combustors are proudly manufactured in the USA. Manufacturing facilities and laboratories are located in Atlanta, Georgia and Laurens, South Carolina.
