It sounds like you need a better electric range. The one in my old house was from the 70's, spiral plug in burners. It's a beast.
The spiral ones I can kinda deal with. When there's enough electrons going thru them I can kinda see how hot they are.
But, when this glass top goes, it's the last one I want in our house. Of course, it's 15 or so years old now, assuming it came with the house when built. Maybe that's part of the problem? With the $450 element fix noted in that post above though, I'm not likely to start exploring why a medium setting one on burner is just that, but the other is more like a medium low and won't heat up my pancake griddle.
First world problem though. I'm not cooking over some rocks with scavenged cow dung for a fuel source.
