So here's the Keg in Black. Last weekend I still lazied out and didn't make the solar heater, however yesterday the weather was sunny and the keg was on a sunny spot for a few hours. It was reported to me that the water was "warm to the hand". I'm not sure what temp is that in Celsius as water colder than body temperature can fall into the category of warm over a certain point.
