Is it possible to have a rocket stove with two exit pipes?

Hello Erica & Ernie,

I see you get a lot of questions. Hope you have some time to give me your thoughts..
Is it possible to have a rocket stove with two exit pipes?

Maybe there exists some system to open/close these pipes so you can choose to heat
the kitchen in the morning and the livingroom (or bath-, bedroom..) in the evening?

Friendly regards,
Sascha

Although I am not Ernie or Erica I'll share my experience. It works on my stove, I have a bypass(straight to the exit stack) to light when cold, an option for the bench, and an option for the tube/shell hot water heat exchanger. All ultimately share the same exit stack but don't need to. You should have some way of priming the various exit options to ensure draft when switching. Canyon

yes we have it setup as a bypass system it works pretty well. you will want to ensure that you have a good seal between the systems or you could get a CO build up in to one you are not using.
I would suggest a T and the flap configured so you dont shut both paths off. (I dont like smoke back). You could also make a really short system for the kitchen that would let you set up a warming oven.
