Twin ovens are not a new concept...as a matter of fact most old french bakeries had twin ovens but...were fired with a separate firebox. You may be able to stack your ovens with possibly one as a "white" oven above and a "pompeii" below.

Let me know on those things and I might be able to steer you in a good direction. Check out my posting on the new oven design on the forum. Might be something of what you are looking for.

Pizza is mainly what I'll be cooking. Might try my hand at some hamburger buns but Pizza is the dish. Think of an aprox. 8 foot wide hallway - length in the hallway is not a problem but depth is. Basically I have a max of 56" of depth but it only leaves me with 36" of walking/working space so long peels would be a problem.

By new oven design do you mean the barrel vault the heaters assoc. built?

Thanks.

Now that I think about it, is there really a difference between the barrel vault and two pompei ovens joined? maybe if you had an elongated pompeii oven that is built more like half of a pill as opposed to half of a ball. you could fire the oven with wood in each door and then slide the coals to the middle between the doors and also some to the far left and right. That might work. Just brainstorming here...

I would second Dutch's idea of the new design concept he posted from MHA. I think you would be able to make that as wide as you like - the trick would be in designing some way of isolating half of it (dry stack firebricks?, a partition that slides between?, a folding removable partition of firebrick splits?).

An interesting problem.

And by "interesting" I mean I'm glad it's not MY problem.

Then again, interesting problems often require innovative solutions that occasionally change the entire paradigm.

I personally like the idea of an elongated MHA oven with dual side openings or the 'half pill' idea with dual openings. I think either is very possible, its figuring out what type of removable/retractable shared wall to use.

The one thing to keep in mind, and I think this was mentioned - The heat up.
Simply building a fire in the middle would not heat up both sides. This would work for keeping the temps up (we all push our fires to the back or to one side after heat up).
Your left with firing one side, then firing up the other side as needed (and having to wait) then combining the fires in the center to support both
OR
Firing the entire (both sides) of the oven each time (one big ass fire!!!).

this is one of those scenarios where I don't think you can have your cake and eat it too.....but a dual, elongated oven is a cool, very cool idea.

The problem with the "pill" shape(spherical ends and cylindrical middle) would most likely be room for the fire. The artigiano shape is about as narrow as one might go, the deeper the oven is the less convection also (I would guess). My brain is telling me that a "stack" of ovens could work. Both could be a "pompeii" with a very shallow ceiling that would vent out the front as usual but for bottom oven (#1) instead of going directly out you could install a diverter and circulate the hot gases beneath the floor of the top oven and up into the chamber(of #2) to vent out the door. When you don't want to heat #2 you could simply divert the exhaust from #1 straight out, when you want the heat switch to heat #2.
Let's see how everyone chews on this idea!

Ya I see what you are getting at there. Could work, but I guess I'm too much of a newb to know for sure. I think I know have more questions than answers haha. Gotta say though, am intrigued by the rotating oven design. That would solve the problem. Now am I crazy enough to attempt building such a thing on my own? Yes, the answer is yes - I just might be

The construction would be pretty straightforward on the oven's themselves. The flue systems you might need to do some research on because you have to make sure gases slow down enough to heat the surface but not so much that the flue system begins to cool and create creosote(fire hazard-BAD ) . The "twister" oven seems like a real winner, seems very simple to use and very user friendly. There was a company that made ovens like that for bakeries as well. would be really difficult to construct one of your own. Hope I can help with some of the questions with some fairly good answers. Check out the other stuff on the MHA site. They have some true "white" ovens that are situated above masonry heaters and that would be similar to the system that would need to be constructed for the stacked ovens. There you will see the routing system for the hot gases as well as where the cleanouts would be located.
All the best!
