Unfortunately, I did not know that cools this supply 24 hours around the clock. I was thinking more that it only cools like a fridge when it is necessary. Aside from the disturbing noise and whistles electricity costs are enormous! The dispenser has within 24 hours 1,45 KWh consumed, according to energy cost meter. This part takes between 40 and 65Watt Watt ...... around the clock without a break !! The part requires more power together than my TV and fridge / freezer. Equivalent to 40 cents electricity costs in 24 hours and 140 Euro Electricity costs per year, alone of the electricity costs can I buy 14 boxes Becks offer :(
