Too bad so sorry but you engrish long nose round eye's can't buy it.

Only for China market first....later you suckers can have ...after we take most profit first..

This is only the last place for that info because some saboteur overzealous moderator quickly deleted at least two threads on this machine since Thursday.

18th's at 1700w isn't a game changer. Plus think of the downtime scrubbing scum from tubes will bring.

There are easy well know solutions to keeping water effectively biologically inactive.
Using distilled de-mineralized water would be a must... and UV is very effective at keeping it biologically inert.
But since water is rather resistant to heat absorption..Glycol AKA "Rad fluid" would become the standard substitute pretty quick I imagine.
Though there are also some more exotic more effective liquids.
But then you are dealing with a closed system that must have fans and airflow and ventilation all over again. Bye bye to your electricity "Savings"

You are correct in noticing the electrical efficiency will be minuscule.
Reliability and service life should increase dramatically...but will probably not offset the huge increase in maintenance costs.
Pumping high volumes of air is always going to be much cheaper than pumping water
And there will never be a better solution to heat dissipation than using mother natures free cold from extreme Northern/Southern latitudes and simple convection.

Further I would speculate the actual added volume/space requirements would be another huge cost for large farms to replace and modify the set-up density.

Bottom line is this a short sighted gimmick. It only give the illusion of increased efficiency.
From a total engineering perspective it significantly increases in-efficiency and risk.
Looks like it was designed to target small scale residential market of hot climates

i think it is actually superb...
If you have a cool water source, you can run them silent and efficient, and even recoup the energy in form of heat, which usually goes out the window.

i love it, and i hope to aquire some very soon.
Now, improve and upgrade to 30Th as the competition does curently, and i'm all ears... :)

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.

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 ;)

Unless your looking forward at a higher price for bitcoin in the future.
Not everything is about the now profits..

So you are saying buying a miner for 0,22 BTC that DOES NOT make 0,17 BTC within 2 years is a great investment?

Well, this is where I pass...  I will NOT buy any miner if the amount of BTC (or BCH, LTC or ETH) is -lower- then the BTC, BCH, LTC, ETH I allready own.
Sorry, but it the most stupid thing you can do with your Cryptoś right now...

Investing and not gainging the amount of BTC you pay ???  Maybe I am stupid, but I don't get that.

Be me guest, if bringing your BTC to lower numbers then you allready own is your goal.

what does it have to do with btc.

I have 2000 usd
I have .3 btc

I buy btc  with the 2000 usd.

and buy the miner.

my btc stays the same.

.3 btc

my cash drops.

I think what he's saying is, if you have 0.3BTC and $2k, you could buy another 0.3BTC with that $2k or buy a miner which, over the next two years, will mine you about 0.2BTC. End result being, if you want more BTC you're better off buying BTC than this miner. Especially if you're looking for a boom in BTC pricing, since with booms come higher diffs which means a lower reward. 0.6BTC now is better than 0.5BTC in two years because 0.6BTC now can *still be* 0.6BTC in two years, guaranteed, while that 0.5BTC is a speculative best-case.

If you're planning on electric radiant heat in floors or a pool, this miner might be a good investment. But if BTC is your primary goal, I can't envision a situation where this machine is worth buying.

I use the tradeblock.com calculator to give me an idea of what the miner will bring in given average changes in diff/month to see my break-even and profit in a year. I usually use 7% diff increase/month (which I should probably increase...) and if I don't see ROI in 6 months, I don't buy the miner. For me, the profit motive portion of mining to acquire more BTC over time than I would receive if I bought BTC with USD or simply held.

So long as mining will net me more BTC than I otherwise would have, ill keep investing in miners/upgrades.

but he is wrong since the reality is I am using cash  not btc to buy the miner.

The fact that I buy whatever in btc  and don't hold the btc has nothing to do with my hodl btc.

He fails to separate and understand he is using cash  and btc has nothing to do with the purchase. Other then as an envelope to deliver the cash to bitmain.

He fails to understand that buying gear and  mining is a completely different animal  then buying coin and holding.  huge issue for me.

He fails to understand that a 45gb miner has $$$  to some as a good space heater.

Myself I can't use this as they lack efficiency of the T2Turbo  and cost 2x that of the standard s9.

If your goal is to mine regardless of profitability, or to make hot water via electricity at reduced cost, this miner is acceptable.

If your goal is to end up with more money (in whatever form) than you started with, this miner is not acceptable.

You're not accounting for that BTC and cash are directly interchangeable. One is the other. That's the whole point of currency. Trading 1BTC for a BTC-making machine that'll only make 0.5BTC is a net loss no matter what currency you started with, unless the heat it makes is worth more than 0.5BTC to you. And that's assuming the substantially increased mechanical complexity doesn't fail first.

Trading cash for power to receive BTC is always a win. Mining altcoin for profits? Be careful with those bags.

I clowned this asic talking with sidehack calling it a CPAP machine. The concept for hobbyists is on point, still not a novice asic. Some say neither are the industrial style but I'd probably start with a cheap s9 or 8 series canaan still.

I think fanatic called it on the other thread, that no farm is going to house these by the 10's of thousands. Though putting 1-5 of these in house would be better for the wife at home and much easier for sound management with all the sealing and acoustic absorption I've done.

Happy wife happy life.   

yeah, we seem to have the same "problems" ;-) at home ...

Seems like a cash grab to sell off the rest of their old S9 parts. I bet they wish they had Yang Zuoxing back.

for those interested, the S9 Hydro is now available on the bitmain.com website - no longer China-only.

Miner itself is $780 USD. With radiator + PSU it comes to $1008 USD or 0.18645827 BTC as of [right now]

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.

I give you an amen on that.

For the whole set we have it listed just over 1.4k. Seems shipping charges are higher for this but the APW5 is 2600w and is $10 less than the APW3++ they have. Since I need 2 more psu for the evga's that arched I'm going to grab these. I'll have to have web check shipping prices for other antminers see if they've change their rates on all their listings.

cool idea but some one has been selling s9 water blocks on ebay for some time now .they cost, it looks like they modded some GPU water blocks to fit S9 hash boards .

https://www.ebay.com/itm/Antminer-s9-Hashboard-with-waterblock/202354553927?hash=item2f1d457447:g:B7oAAOSwyLdbNkAn

This does look cool but nothing new and more to get money for old chips for bitmain I'm guessing, which it will sell . now if the S11 or what ever they call there 7nm chip model does this at 32 th or higher using like 1400 watts that might be  something to look at maybe .

What I hope happens, later on is some one figures out a way to lower the power use age as the hash goes up at some point they will have to. it's possible but when is the question.

Another overclock S9? with liquid cooler original S9 can crank up high freq i think..its cooler and silent

I was waiting for something like this for a long long time.. well I have been waiting since 1TH/s Antminer C1 became obsolete... I used those to warm my house 2 years... They are quiet, emit heat and I can get my heating expense back.. well using C1's I even had some "left overs" :)

I definitely plan to get one or two if the get little cheaper.. lets say.. 2x cheaper :)

Some of the product information seems to now be listed on the main bitmain website around the $745 range.

its essentially just an S9 (i/j)
It has four hashboards, so obviously it hashes 1/3rd higher, and uses 1/3rd more power. Effectively its just 1 1/3th S9 in one housing, wich is possible due more effective heat transfer.
It saves space, less noise, re-usable heat (if you can), and less problems especially in warmer aeas.
I see the benefits....
Only pitty is: why do this with 2.5 year old technology instead of the newer technology that all competitors have...?

I was thinking that myself,it made me think of the C1 .  The ant C1 was a over clocked ant S3 .




I still have one working C1. same  i might buy one.


They did one time then stopped because of greed which I'm guessing will be the reason they don't again > greed.

Hint Antminer C1 an you could use the water blocks from the C1 on the antminer S5's which may happen again with the S11 etc .

So tempting to just grab one of these since I need psu's. .. . then I think of my exhaust project getting finished.

Hopefully it is just to sell off their inventory of remaining chips and deal with any customer issues that arise due to liquid cooling before they roll out the S11. 

they have yet  to build a good chip since losing the chip designer to whatsminer this seems to have really set them back.

Maybe  there won't be an s11 until they  rob a design from the other builders.

You mean one water connection starts to leak and sprays water over your 20 other miners... yeah that might cause a call or two to the support :)

you do realize  that  distilled water  does not conduct power.

I have had leaks in water cooled systems  and you don't kill the system  if you have distilled water in it.

I may grab one of these devices just for the reduction in noise as a result of the liquid cooling (45-58dB according to the site listing), and the thing just looks interesting to work with overall. This is obviously a bit of a novelty device like the C1 was due to the radiator and all, and it’s likely an attempt from Bitmain to offload existing S9 stock or chips, but it’s been a while since Bitmain has officially released any watercooled equipment, and I’m excited to see how these things actually turn out.

I wonder if it’ll be possible to use an aftermarket radiator and pump on one of these things. $130 seems like a somewhat hefty price to pay for their radiator.

Since temp changed here in the NW 80% fan speed has been very welcome on my ears on the s9's. I want to try one of these too. Hoping to order in a month or so and place in office. Though Bitmain radiator looks to have a number of 120mm fam makes me wonder some on dbs.

Hello,
i had one S9 Hydro. Of course, it got under way to see its interior ;)

My Hydro also runs since about 2 month... did anyone put this system to a external heat exchanger and feed his heating system at home??

My plan is to use 3 hydros and put it to an ex heatexchanger that is connected to a 1000l heating tank to heat about 300m² with about 33° water temp.

Any news about the noise of the miner itself?
Are the fans on the radiator monitored as well? (can they be deleted?)
