So, unless you live somewhere that gets 26 hrs of sun every day I think you'll be ok :laughing-rolling: 8-}

It will heat up in a few hours with the additional hot output from the still...this refers to passive heat I think.... My experience is that in summer an IBC can reach temperatures of 40 degrees in a few hours when you combine the gradual rise due to environment with the hot water from the cooling system... I have tried a heat exchange plate in an ice slurry before the return to the cooling tank...but found it useless after 1/2 hour or so...It was a 1000 litre tank with a large 6 foot wine heat exchange plate. But it struggled to keep up... I now think that the best idea is two reservoirs one for the line out cool water and one for the line in hot water ...the tanks can be interconnected to allow the cooling water to slowly re-integrate with the cooler water in the line out tank.

But i get the point your making, the shade is more to protect the plastic that holds the water as even UV stabilised plastic still gets brittle over time.
But if you could use sub 30°C cooling water you would wouldnt you

Just wondering doc was the reason it didn't work well because the ice wouldn't last that long? my plan was to have a line in block and a line out block bringing the temp down both ways and the ice bath was only a temp solution I planned to have them sitting in my cool room with a small tank of glycol recirculating through both.
