The manual on my Climadiff states that it uses about 154 kWh per year.....This compares with about 700kWh for an average fridge, which is logical as its internal temp. is 12C rather than 3-4C and it doesn't get opened nearly so often. Assuming most of this translates into heat somewhere I'm sure some bright spark could compute the effect on room temperature, but I'll bet it isn't very much. The multitemperature wine fridges would push out more heat I'm sure, as would those with glass doors.I'm just wondering to what extent a Liebherr will warm up the rest of the cellar/garage/room? My Liebherr is in my spare room, along with a lot of other bottles. I've stored wine in my spare room for many years. I keep the temperature down by keeping the curtains drawn and the radiator drawn. This has usually worked well but in recent years I have noticed that some wines have not lasted as well as one might expect. A couple of 1er crus Burgs from 1996 were out of condition earlier this year, to give one example. I had put this down to global warming but I wonder if the heat pumped out by the Liebherr is also a factor.
