Castleton

About the Castleton

Clean and efficient with extra long burn times. The Castleton has all the essential features of a modern-day wood burning stove.

A 4-tube secondary combustion system with a fixed baffle ensures a clean burn before the catalyst performs the finishing touches. The square shape of the Castleton creates a 19″ wide by 17″ deep firebox. It is perfect for loading and arranging firewood. Turn your stove to high and stoke a big fire. Turn it all the way down to keep a fire burning overnight.
