Website says the oven maintains an even temp of 500. My home oven does a fantastic job of that.
But, you're home oven doesn't have a well insulated hearth built with (most likely) 2 1/2" thick firebrick. 500 with that much thermal mass probably translates into the equivalent of 625 in a home oven with a typical 1/2" stone.
Why someone would pay thousands for a WFO oven, though, and then run it at NY temps- the logic of THAT complete escapes me.
