hello all , i have my stove burning from the top only , or should i say secondaries only no flames from the wood or not really and red coals, is this good or bad? i was told that the secondaries give more heat hence the reason behind it. i dont have any tubes in feeding air just a vermiculite baffle i created my self instead of the steel one, secondaries seem to work fine but them alone how efficient is it to do it? , i can post links for vids
