I'm surprised at all the pro glass top comments. One of my brothers had one. I don't know if it was a couple of spills that got "burnt in" or whether the pans they used were unsuitable for the surface or what but it became an uncleanabe mess with rough circular patches in no time. My impression is that they may be OK if you treat them with kid gloves and for all I know even have to change all your existing cookware...

I find that people have very different likes with types of cooker. Pip gets on well with the old solid electric plates and knows exactly when to change the heat (including turning off for the last bit of cooking) but I struggle with something that slow and am constantly juggling saucepans as I find something has got too hot.

My ideal combination is a gas hob and a fan assisted electric oven. I had that set up when I had a flat and liked it. I found the hob easy to clean too. The top burner parts just lifted off so I washed them in the sink and gave the top a clean before putting the bits back on.

Barry, are you talking complete output for oven and hobs? According to the manual, the total output for our electric cooker is around 10KW which I get to 34,000 btu/h.
