Dual fuel range cooker (Sheringham NR26)

This Smeg brushed stainless steel range cooker is 90cm wide, 60cm deep, and 92cm high. It has 6 gas rings on the hob, with two fan assisted electric ovens below. It all works OK, but is not particularly powerful. It should be perfectly OK for a family, but struggles to cope with bulk cooking for dozens of people, which is what we have been trying to do! It sits on 4 plastic feet, one of which has broken - it could be glued back once the cooker is in place.
