How the hell do you get your electric oven to 450 degrees celcius?
First of all, this a homebuild oven, i had full control in how to reach these temperatures, and i even reached a temperature of 600 degree celsius.
Before i started building i studied commercial pizza ovens.
I saw that most ovens runned on 380volt and where about 3 kilowatts or more, in that way you must have a 3 fase connection in your home what is expensive to have installed, and those professional ovens are expensive to.
I just recalculated wattage (power consumption) into oven size, because these ovens are mutch bigger.
In that way you can calculate oven volume into power consumption, just make it smaller is the answer.
That became totally clear when i found the first ovens that did run on normal 220volts, from the brand Diamond.
The inner measures of these ovens where about 40*40*20 cm, and they consumed about 2 kilowatts.
My oven is made out of a metal box with the measures of about 41*41*18cm and cunsumes also 2000watts.
The inner space of my oven is even some smaller because i had those durox stones placed of 3 cm thick because they hold the heating wires, you cant connect them to metal.
All must be heated, plus these stones, so you have the same power consumption.
It is just recalculated the resistance of the heating wire into wattage, thats just a electrical formula. ( W=I*U) and (U=I*R)
To reach these temperatures in a normal oven is a total differend story, the heating element has to less power or wattage, and the ovens are way to big in size, they reach about 250 degree celsius, and end story.
The only thing you can do is to resize it ( chainsaw
) slice a big piece out of the middle and mount it back together.
And even than its the question if you can reach 450 celsius because the heating element has to less power, it must be around 2000 watts in those sizes i spoke of.
The only thing what you can do is to buy a old oven and take the heating element out, and mount that in your oven on the top or bottem ( parallel connected), or you must have ( a to big oven ) oven with a power consumption of 1800 watts and just make it smaller.
You can also buy this heating wire, and place that in your oven, just on the bottem mounted on durox connected parallel.
With other words you will be building it in the same way as i did, and you must have some electrical understanding how to connect these elements safe to reach those temperatures.
I just started from the bottem and build it all myself.
I could have bought that Diamond oven, but it costed about 1000 dollar, my own oven costed me around 100 dollar, but that could be even less if have the right materials at home, plating, stones, isolation and so on.
The biggest problem with good pizza is the oven, thats for sure.
