DIY chiller idea

[mark]

Always can dig a hole in the backyard. Dig deep and ground soil temps stay around 50°F year round (examples for Lacombe and Lethbridge CDS sites).

There's a few good threads on geo-loops on RC for cooling (here's one) just need a cooling loop, titanium's nice, dump your ro/di waste into the hole to the distribute the heat, thermostats, a pump, etc. Guess too for the cost could get a chiller.
