I'm riviving this thread to show you a project I did in 2015.
I was heating a pool and cooling two Antminer C1. The miners were running super cool and the pool was a lot more enjoyable. Because were I live a pool rarely goes higher than 25.5C (85F) without heating. I was running two C1 in series with one pump and a stainless coil in a pool for cooling.
