When the probe inside reach 842°F the top heating element shut off, you what it always glowing red because the air temperature drasticly drop when you open the door of the oven to put the pie in (and turn it halway for an even cooking) it's not good for short baking time, because the air need more time to warm up, or it need to be constant.
With the height of this dome, 800F (with a 42 degree buffer to make sure the upper element stays on), isn't bad for Neapolitan, but I'll concede that if the oven is insulated well enough for 900F on top, then perhaps a thermostat mod might not be a bad idea.
Scott, Leaufroide P22 is even more powerfull, I've done the maths
It's a twice 3.25" x 20.75" x 20.75" Deck but he only uses the top, the bottom is filled with refractory bricks, and he uses 2x 1450W heating element for the top.
P22: 7.90W/cm3 P134H: 7.59W/cm3
I did not take into account the lower resistances.
Sub, I'm confused about a couple things. Is Leaufroide = Baker's Pride? Who is 'He?' Is it the person in the video that was linked to earlier?
When you talk about the bottom being filled with bricks are you referring to this person's modified version or does the P22 ship like that?
Btw, from another video of the same individual, it appears that the bottom baking chamber has a broiler in the top of it (or the bottom pizza wouldn't brown):
My calculator makes the assumption that a 2 deck oven has 3 elements- 1 under the bottom stone, 1 under the middle stone and 1 under the ceiling. If the P22 doesn't have an element under the bottom stone, then, looking at the specs, it references 3.6 kw, translating into two 1.8 kw elements. 1,800 watts divided by 430 square inches (the area of each deck) equals about 4 watts per square inch. That's still half the watts per square inch of the P134H.
Also, while we're on the topic of P22s, I took a good look at the pizzas the person in the link is making, and, while they look great, they're not, imo, anywhere near Neapolitan- like Seb's are. Even with a doubled up resistor, the P22 is a vastly inferior oven to the P134H.
