Rocket Stoves burn wood very hot, clean and fast. With this Heat Exchanger will pull more heat out of the chimney where heat is concentrated on rocket heaters and stoves. Our Gasifier stove allows you to heat a much larger space while not restricting venting draft like our old griddle. This allows the stove to breathe better, burn cleaner even with air flow turned down.  Heat exchanger can not be used with 50BMG TEG stove without an adapter. Call for pricing.
