Now think about a kettle to boil water for tea.
If you wanted a tea at 17:00 would you heat it up at 10:00 in the morning? No, because it would be cold by 17:00 and you would have to heat up again, wasting more energy.
But this is what is happening with your electric water heater!
As soon as finish to shower your electric water heater starts to heat up water straight away even though most probably you will only need hot water again by the end of the day or next morning. Even with insulation, it needs to turn ON several times during the day to keep the water hot inside, since heat can escape through its walls.
The hotter it is inside, the more heat, energy and money will be lost.
A standard 80L electric water heater wastes ~1.2kWh/day of heat through their walls, representing 64 EUR/year*!
In Europe there is an estimate of 28 mio. electric water heater installed which gives 12,264,000,000 kWh per year of wasted energy. This represents the same emissions of 2 mio. cars on the roads in one year, or 2 coal-fired power plants (BTW bigger tanks bigger waste)!
Because of this, blankets for water heater are actually a thing 😵 Check this guy!
