@ryder72, which Gutmann hob do you have if you don't mind me asking? I did look at them, although I've struggled to find much information. The kicthen companies I've been dealing with all recommend Bora, but none of them have even mentioned Gutmann, maybe it's not that well known in the UK.
What has put me off a little is the cooking zones on the Gutmann hobs seem to be a max of 22cm. A couple of my favourite pans are 24cm diameter, and I have a 26cm frying pan. The Bora Basic BFIA model has a 23cm diameter heating zone which is closer. The Siemens is 24cm.
Maybe I'm worrying too much about a cm or two, but I love cooking and want things to work properly, and from what I understand of induction hobs (I have only had gas up until now), if the cooking zone isn't as big as the pan, there's likely to be cold sopts around the edges. Do you use any large pans on your hob and if so, how do you find them?
