The unit is very quiet and even below still applies the specified power consumption of 100kWh proJahr. I use the device in the basement with the spacers supplied. The current measurement with Fritz! Dect 200 egab an average daily electricity consumption of 0,233 kWh / day. This corresponds to an annual consumption of 85 kWh - super. The consumption is affected of course by the individual use of the freezer. Frequent opening of the door and freezing food, increase power consumption.
