Our electric AGA with companion is about 20 years' old. Beautiful to look at but was costing us around £5K pa in electricity when left on constantly so we had it adapted around 18 months ago and now you have to turn it on and off like any conventional oven. So now our electricity bills are far lower BUT we don't get any of the advantages of an AGA any more and the oven takes ages to heat up and even then I am not sure it is getting hot enough. So I think it is time to change to something else. I would be interested to hear peoples' views on electric (not induction) range ovens (we are rural and don't have gas). Thank you
