If you want to save on electricity here are a few tips:
Install a timer for the boiler instead if burning 24/7
Use a steamer so only one ring is reqired for vegetables etc
We have Been to a company in Los Alcazares called Iberswitch who source the cheapest supplier and facilitate the switch, for a small charge. Our son used them and has saved a lot of money after living here for 12 years
If you want any more info we are here until early July
