I have the chest now one week. It depends since the first connection on Ernrgieverbrauchsmessgerät. The following data: average daily consumption 24 h 312 watts, which is 0.3 kWh outside temperature 24-28 degrees C, room temperature in the basement 18 degrees C. Years extrapolation: annual consumption ca 115 kWh costs about 32 Old chest 750 kWh costs about 165 The new cabinet has paid for itself in about 3 years, what values are excellent. I can recommend it only. I would like to say to the delivery service: 2 man delivery service, the two have taken the chest down to the basement, unpacked, inspected for errors and took the package. Also of note, the chest before turning on leave for about three hours. Providing an outstanding service. I can see the dealer and the takeaway only recommend. Full marks.
