actually it is the same thing for storage vs stiebel. Storage heater consumes 3kW while stievel 7kW.

Assuming u r using a 25litres storage heater like JOVEN JH 25. U nd 2 wait 5 minutes for it to boil and you shower 10 minutes. (to make things simple, we assume kW consumption is per minute)

Total kW Consumed (Storage) = 15 x 3 = 45kW

Total kW Consumed (Stiebel) = 10 x 7 = 70kW
