We currently have an old 250litre electric heater that is dying.We are heating this twice daily using CL2 but regularly run out of hot water in the evening.Considering replacing with a 315litre and staying on CL2 twice daily heating or going to a 400litre and heating just once a day off peak.Has anyone done similar?Am trying to use calculators to work out best option but it’s so complicated.any advice is much appreciated?
