i cant speak for CK but i am an engineer and just making a blanket statement that both systems have the same features so they should act the same is not accurate. it might indicate that it would act similarly but even that can get thrown out the window in real life.
i think one of the key differances here is the yukon furnace was engineered and designed from the beginning with these tubes. i am sure they performed hundreds of man hours of testing with lab equipment to prove that there design is the safest and most economical design that they can get.
i used to work at a furnace company and have a good friend who still works there in engineering. they are NOT just throwing parts together and calling it good. there are allot of design iterations and thorough testing to be done.
back a long time ago i had a similar heat extractor on one of my shop wood stoves. it didnt last long because it got clogged up with crap and started restricting flow.
it might work fine for you but the general consensus is it is not recommended. it is generally not worth the extra hassle and work for the extra heat you might get out of it.
i hope this might help clear your question up, each stove is its own design with its own quarkes and natural running tendancies. if it works for you great, i hope it treat you well.
