Looking to replace gas hob with electric and cant decide between Induction ( seems the best) or Ceramic. Wife has got her eye on Induction hob that works off 13a plug as we don't have enough power in kitchen, but it appears that all 4 rings cannot be used at the same time? Also i'm told that with induction you can only use certain pans, stainless etc, anyone got any experience with them? Any help is appreciated TIA
