In the apartment, heating and hot water are provided by electrical energy. Heating and heating does not take place for 24 hours, but only for the "low tariff" period.
There is no problem with heating. But with warm water, you need to manage it. The boiler has a capacity of 120 liters and is heated only twice a day at these times:
Monday - Friday from 0:25 to 5:55 and from 15:10 to 17:45. Weekends and public holidays from 3:00 to 8:00 and from 13:05 to 16:05.
It is my fault this information was not in my guide. Sorry, now it is possible to find it.
