Vertical tubes in the firebox increase the steel heating surface area by approximately 50%. This will create a natural hot air draft inside the tube and will draw cool air off the floor. The hot air produced by convection will constantly circulate through your house with no electrical blowers or fans, meaning even heat through your home.


The DS Regulator is not electrical. It uses two different metals bonded
together. The metals expand and contract based on temperature, directing the heat to where it is needed. Mounted directly on the hot surface of the stove, it governs the temperature by opening or closing the draft control. This draft control connects to a specially designed draft intake, through which air can enter to increase or decrease the temperature of the fire, depending on the heat radiated from the stove. The DS Regulator is equipped with a 5-position mechanical control dial.
