Does Anyone have a Commercial Range/oven in their residence? I have some questions.

[HBARleatherneck]

We are at the point where a commercial 6 burner range with griddle would make life much easier.

I know that some insurance companies have a problem with this.
I know some companies void the warranty if used in a residence. No problem we are buying used.
I know that a commercial hood and perhaps a halon type system might be necessary.
I understand there are a lot more btus involved, I have researched it and compared.
I understand that more clearances are required, no problem here.

My question is more along the lines of how much heat did the pilot lights add to your home temp? How much more gas do you think you use a month to keep the larger multiple pilots lit? A range like we are looking at has 10 pilot lights.

Any other advice you have..other than "Dont do it"? Unless you have real experience with it. Otherwise we will be going to 2 full size ranges and a separate 24" griddle.

The range we are looking at is NG, I would convert it to LP. It is a 60" 6 burner with 24" griddle and 2 26" wide ovens. Full baking sheet size.
