SINGLE Phase Electric Oven: considerations

I'm looking at purchasing an electric oven.  Each deck requires a 30 Amp service, and since I'm looking at 2 or three decks, each with a three pan capacity, I'm going to have to increase my amp service by another 200 amps.

While I've inquired about 3 phase power the cost would be prohibitive.  So what I'm looking at is buying an oven in single phase.

My question is this:

Are there any downsides to purchasing an oven in single phase?

My other option would seem to be buying a phase converter.  I'm not fond of them.  I have one for my sheeter, a rotary phase converter, and it's not quiet, but presuming I had to go that route I could always put the phase converter outside of my building in an insulated box so that I wouldn't have to listen to it as I bake.

 

Thoughts?

Phase converters use a lot of electricity; I do not recommend it.  Plus they break eventually.  Is it impossible to get a gas oven?  They are usually cheaper to run and less easy to break.

No.  I have a gas oven, a pizza oven actually, and the footprint of even the smallest gas ovens I've seen is, I'm afraid, too large for my space.

i bought 2 bake off/combi ovens which can be either 3 phase or single phase they do use a bit more power on a single phase connection 

one is a salva k5 which is 5 grid and 6kw the other is a unox xl505 and xb603 5 grid but also has a prover which uses 9kw combined, the prover is a seperate unit which plugs in on 13 amp plug but is controlled by the oven control unit

i removed the salva and have just had the unox wired in on a 10mm wiring 40amp rcd

ive also cut a 15mm sheet of granite worktop i got from a salvage yard to 600x400 on bottom runner for oven bottom breads and its working well, and the steam injection certainly helps oven spring

im also in the process of making a clay wood fired oven in my garden with a granite sole made from the leftover granite worktops
