Mine is in a room with about 25 degrees and the wine is still cooled down to 12 degrees.

We never have 25 degrees in the room (kitchen) - but with an outside temperature of 25 degrees, it depends on whether this temperature has an influence on your room. We never had any problems, but as I said, the sun almost never shines into the kitchen. Setting 8 degrees WW/13 degrees RW - Kind regards.
