After much research I decided on the hot water tank Stiebel Eltron UFP5T. Ordered and the delivery was made in the usual very short time. The device makes a very well-made impression. Rear is a separate sheet rail temporarily taped, which is fixed with 2 screws in the lower cabinet. By this we hung the device ready. Only then fill up no more bubbles come and only afterwards the power plug into the socket.
Water supply hoses are not supplied, but they are either present or anyway favorable to get additionally. For existing hoses using new gaskets is recommended!
Indicated a standby current consumption of 0,23kW / 24. Now it has to make in the coming days time, own measurements (without water withdrawal) and the readings to be averaged, also at a water temperature of 60 degrees. Result: 0,205kW / 24h! Power depending on the tariff ie an annual saving of approximately 27 euros electricity costs compared to the old unit :-)
The device remains almost completely cold, only the front of the groove (the vertical indentation below the temperature selector) is there minimal warm. Had this indentation, the well is only designerischen aspects omitted, a few millimeters would be at this point but more space for insulation available. But anyway, precisely because of demonstrably very low standby power consumption: full marks! I am very satisfied, Stiebel Eltron.
