While I wait for my estimates for the gas line, here are duel fuel ranges. I can't find any with 4 burners, all have a 5th one. Which of these look good?
What is the stated purpose of those oblong middle/fifth burners?
For a 30" wide stove, I'd want to be able to have two big pots going over big BTU burners, and then have two other burners available for normal sized pots. My stove is over the top (six burners, 48" wide). Each grate is 14" wide -- more than enough space for big pots and to use a big griddle pan.
I've never had all six burners on at the same time. May not have ever had four going at the same time. So all those other burners are mostly used as counter/holding space. Nice to have, not a must have.
