Residential - yes, but not that good in a hot climate. Those large radiators are harder to vent outside than a plain S9 with some ducts. But works great in a cold climate during the winter - free quiet heat.

The way to run these is having a well pump water into a drum and have closed loop water supplies running to each miner (and don't use the radiator). Using the radiator would be senseless for venting the air out of the mining space. You would just need some circulating pumps (get a three speed and set for 40 psi) and a bladder to distribute each water lead. If the hashrate was a bit higher, I would order some.

Seems, nobody is willing to do the math... It is a worthless piece of shit even with -free- energy...

18TH mines 0.0007 BTC a day x 365 days = 0,2555 BTC a year without diff and hashrate going up.
Roughly every year the mining power triples, so 0,2555 BTC \ 3 = 0,0852 BTC a year taken in the diff and hashrate rising.
(Again, I do not count energy. Presume you have this free for this calculation)

Even mining 2 years = 0,0852 BTC x 2 = 0,17 BTC mined in 2 years (not even mentioning the diff and hasrate rising in 2020!)

Costs of the miner are (for me in the EU with VAT and import) +- 1300 euro (without PSU) = 0,22 BTC cost of the S9 Hydro right now.

Simply said; You're better off keeping your BTC in your pocket and skip this garden hose miner Wink

I give you an amen on that.
