My husband and i are eager to build a pizza oven which integrates mass-heating technologies (we eat allot of pizza and want to smartly heat our home while doing so). All research I've done has only allowed one or the other (either mass heater or pizza oven). Due to the cost and effort and spacial position (its on the centre of our home) of the oven we cant take any risks for it to flop. Please shower me with some wisdom.
I'm afraid that my pizza oven smokes me out of the house if the chimney chambers suddenly start meandering. I'm research heavy and practically light (we've never built a mass heater or pizza oven before, but I do know that woodburning fireplaces are NOT what i want (I'm practically sitting on top of one right now just to gather a little heat.)
We've been building our off-grid home for 9 years and plan to move in around December 2018. So we can't afford to mess this oven up - it'll be in the centre of our home. Help!
Have you seen Matt Walkers Tiny house cook stove? here is a link to the post https://permies.com/t/71700/Tiny-House-Cook-Stove-Heater. It might be just what your looking for. It does not have to be a mass heater, just an oven.
Not sure how big a pizza it fits but its worth looking at.
I think Matt's tiny house cook stove would work as a pizza oven, with the addition of an insulating cover for the cooktop. This would probably work best as a three sides and top unit, with a removable door side. It might also be practical to have the pizza enclosure removable if it is lightweight fiber construction with a sheet metal shell, either hinged in back to tip up, or on pulleys to raise up, so the cooktop can be used normally when not baking pizza.
The design allows for running the exhaust directly to the chimney or through a mass depending on damper position, so you would have some control over how much it was heating your house.
Thank you SO much for the responses! I love Matts oven but the cob oven is more of what i had in mind. I was hoping that it would be possible to use the flue from the cob oven to integrate into a mass heater (allow the flue to rise say 500mm and then add an elbow to start redirecting the smoke/heat)? Or would this negatively influence the ovens draw?
I have not worked with a cob oven, but my guess is, NO you won't be able to redirect the exhaust . However I suspect that it will produce all the heat you need in S. Africa.just the way it is.
Someone who has lived with a cob oven might have a better idea if it were possible.
