A. How much did this cost you, surely phase change would have been cheaper?
Don't get me wrong, this is full of awesomeness, but I just don't know why. Are you a millionaire who doesn't work anymore?
It cost a bit more than $500, the same as my dual loop setups pumps, tops, radiators, fans and fittings. Going 80 feet down the hill with extra piping and insulating it took up $120 of that. Routing to the utility room for the pump/res location cost at least $65. The unnecessary filter was $35. I could have kept it just under $300 by directly coming into the computer area with the loop buried closer.
The long term cost is only the pumps electricity usage which varies from 65-80w depending on the restriction. That's efficient chilling!
Iwaki pump: $85.53 shipped
300' geothermal pipe: $98.53 shipped
144' 5/8th wall insulation: $53.67 shipped
Why? Because it was cheaper than switching to low fpi radiators with silent fans. My fans were driving me nuts and the loops didn't cool as well as I needed.
Most importantly it was fun to plan and design it.
