I live in a modern 2 bed flat with all electric heating. With an electric shower, I have no real use for instant hot water, other than to fill the kitchen sink for washing dishes each evening.
I have been starting to wonder if turning on the 2x 3Kw immersion water heater with a 120 litre capacity for one hour each evening is being energy efficient, just to fill the sink with 8-10 litres of hot water.
I have been considering is the purchase of a 3.5 litre whistle kettle which would take 15 minutes to boil with the electric hobs largest ring on full. Also the cooker hood fan would need to be on for the duration. This is still not enough hot water though so would also need to fill my existing 1.5 litre electric kettle for 3 minutes to boil.
Would I be better better off (energy consumption wise) continuing to use my immersion heater or opt for the kettle option?
Thanks!
