Sorry if I maybe using incorrect words, English is not my first language. I’m in France and there’s a big electric water boiler which provides all the hot water in our apartment. I have 2 questions regarding the energy consumption:
1. I suppose it consumes electricity initially to heat the water inside, but does it keep consuming to keep them warm?
2. Between 10pm – 6am, the electricity cost is lower in our plan. Does that mean it costs us less if we use the hot water(shower/dishes) between these times?
Cheers!

Heat will slowly leak out into the surrounding environment and the boiler’s thermostat will switch on every once in a while to maintain the set temperature. How much heat is lost depends on the insulation of the boiler.
You might save some money if you use water at night, because then the boiler will have to be on all the time until the water is heated up. You want to be using the water between 0:00 and 3:00 hours to give plenty of time for the boiler to reheat before the price increases again.
Look carefully at the electricity price to see if such micromanagement is worthwile. You might find that the “distribution fee” is the same at night, and not all nights are cheap on NordPool.
