Sorry it took awhile to get back to you. I did a little experiment. There are 5 burners. I put 4 cups of water in a pan and tested how long it took each burner to boil water. I cooled the pan between tests and no lid was placed on the pan during warm up. It took the burners 5,7,7,7 and 6 minutes to boil the 4 cups of water. That doesn't seem bad to me. How about you? I do know that when we cook for large groups and we have a large pot of something like corn on the cob to boil, it just takes forever and ever...and almost won't boil without a lid on it. We have had electric cooktops in the past, but never felt they took as long to cook with. Thoughts?
