Does electric home boiler consume electricity all the time?

Question

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!
