Sounds more like a conventional ceramic hob to me.
Can you tell us what make/model it is? (Any user instructions left in the kitchen drawers for you?) Sometimes you can identify an unknown make/type just from spending ten minutes with Google images.
Agree that an induction hob is generally the best choice for a replacement. Frankly, none of them give you quite as much controllability as a gas hob, and they also won't take a cast iron steak griddle. (Surprise, surprise.) But we're still glad we bought our AEG.
There was another thread on this subject a couple of months ago. (
viewtopic.php?f=14&t=41878&hilit=induction+hob) You might find that some of your pans won't play ball with an induction hob, buut in our case that was only one out of twelve.
And don't buy an induction that plugs into a 13 amp socket, unless you're happy with the likelihood that it won't be able to give you four (or maybe even three) rings on power at once. (Duhhh, you just can't raise that number of kilowatts from a 13 amp plug.
) Instead, go for one that installs into a proper cooker circuit with the right heavy-amp cable.
