I have worked out the ampage and I dont think its a good idea to install 5 panel heaters with a cooker circuit, shower all these turned on at once 43.45+45 and whatever an electric cooker takes be over the dno fuse whatever it is 80 or 100 amp have to do with a gas cooker or put in less panel heaters and update the existing old gas fires to new gas fires in the bedrooms to get the ampage down!
