IMPORTANT UPDATE!!! That particular brazed plate heat exchanger is the wrong thing. Chlorine eats copper brazing, so it would eventually leak and mix pool water into my ASIC tank. You need to look up an all stainless steel heat exchanger for pools. Thank you!
Thanks for the heads up. One thing I don't seem to get about the heat exchanger line. You've got your 2nd pump to pull the hot liquid from the tabk to one side of the heat exchanger, but how does chilled water from the pool get into the heat exchanger?
@@jmaus2k as I understand it double walled means when there is a leak the two liquids don't mix, they leak out the bottom. It's not so you can drink the pool water without getting oil in your mouth, it's so you can submerge 20k worth of miner in oil without getting pool water in it!
Has the pool equalized in temperature yet? I'm sure you have been taking temps to see where outside heat loss matches the input from the mining heater.
I was a little concerned about the mixed reviews, but I used it last year and hooked it up again this year and it was great th-cam.com/users/postUgkx-izdrK3eF-HMvjzeBOxToD6Fx-4ulJUh . I couldn't get my 10' Intex pool above 76 degrees the year prior and last year I got it to 90 and had to put ice in it. This worked so well! I have just 1 mat hooked up to a 1,000 GPH Intex pump and it makes a significant reduction in the flow rate coming back into the pool, but that is to be expected with how far the water has to travel through the mat.
I can't imagine having an open fluid system without some kind of filtration. I'm curious what this fluid looks like after a year. I'd add filtration to those over flow holes.
Cool to hear this creative approach and update on multiple attempts! Air cooled mining can work for heating bit needs quite a bit of modding to make them quiet.
This is really cool. what would be more officiant is using the pools pump that circulates the water to enter and exit a heat exchange. then the water would discharge from the pool jets and one less pump to operate. great work
I had thought about that, except the pools pump doesnt run 100% of the time. Its on a cycle of like 8 hours off per day - which would affect the cooling of the miners pretty bad.. I could, I guess, turn the pump way down and have it run all the time and get that effect
When those type of heat exchangers fail it’s usually a leak that causes the 2 fluids to mix. I would think about a system to monitor that. I image pool water in your cooling tank would fry your miners. Proof testing your heat exchanger periodically wouldn’t be a bad idea.
What kind of system could monitor that? Can you do it with differential pressure somehow? I'm guessing a floatless level sensor detects it as the smoke comes out of your system. Red food dye in the pool would work if you watched it all the time.
you could have redundancy by separating the miner loop and the water loop by putting a closed loop of non-conductive liquid with a heat exchanger on both sides. that way both heat exchangers have to fail to cause damage, and the closed middle loop could have a dye to detect a leak in either heat exchanger.
Consider installing vents at the highest point where the pipes run. The next time you start the system, you won't have to cut the tubing. Greetings from DCX :)
I had some in my drawings, not sure why I didn’t follow my own plan. Hello, DCX! I’ve got some friends who’ve ordered your kits and I can’t wait to see them arrive and installed
Getting better, I look forward to version 25 followed by the video how I sold my house to pay for cooling solutions. At 500 watts for future graphics cards I look forward to crazy cooling solutions making a comeback. I remember seeing people putting gpu water coolers through concrete slabs.
So you have two pumps. Is that so you dont have to have your pool filter/pump running. Or would you have to have that running as well as the two other pumps in the video.
Correct - plus I didnt want THAT much water rushing through the heat exchanger.. My main pool pump is like 50 times stronger than the one pumping pool water through this loop.

@@Nato3713 that is correct. Two March mdx pumps with viton seals for the Bitcool side, and one cheap plastic little 8 gallon per minute submersible pump in the pool, pushing water into the heat exchanger and back to the pool

Im not sure where the mud would come from, but it could definitely collect dust.. I dont have a filter in this one - its a prototype for a future project
They would work incredibly well! You could set up a seperate line with a radiator in your basement and pump heat into the whole house. Or the garage, possibilities are endless

Well, unfortunately, I quickly discovered that brazed plate copper heat exchangers get dissolved slowly by chlorine! I need to swap out for a stainless steel heat exchanger.

@@SPACEDESIGNWAREHOUSE 10 degrees in 2 days, ya I'd say it's working well! How did you learn it dissolves, and how slow is slow?

I have a discord channel for my TH-cam and there’s an HVAC guy in there who told me to look into chlorine reacting with copper brazed plate heat exchangers and I found that they will corrode “pretty fast.” There are a ton of variables but heat speeds things up and that’s sort of the entire point of the thing.. It won’t happen in days, but it’s unclear how many weeks it’ll be before the water eventually mixes with the coolant and that would be very bad
@@SPACEDESIGNWAREHOUSE Fair enough. Gonna see how long he's been using it and any issues. I'll also warn him about that potential serious problem.. Thanks!
You mention that the setup was sufficient to keep up with the cooling of your two S19j Pros. I'm curious if that was with the pool in the loop or not. I'm working on my own set of tanks and the one part I have no idea about is the amount of heat those radiators can reject...even ballpark would be helpful to know.
These radiators are sufficient to keep two miners cool, but you have to be really careful about the flow of the coolant up through the machines. If your nozzle is positioned in such a way where the flow is biased to one side, it will cool one miner MUCH more than the other and not work well enough.. Engineered Fluids uses flow plates to make this work - I just had to play around with the nozzle position a bunch; but this radiator can handle both units without the pool
@@SPACEDESIGNWAREHOUSE wow, even with the overclock to 125gh? Either way, super cool videos! looking forward to seeing what's next. Not 100% sure what a flow plate is, but I'll head on over to the great google and see what I can dig up.
What tank are you using/materials? These look like electrical control cabinets ? Thanks for all the awesome videos, love the honesty of them showing all the issues etc
I got super backed up with projects and real life and I slapped two radiators on those lines and that’s how it’s been running for the last month. But I’ve got the thing!! Starting in a couple weeks I’ll stop traveling and get back to these projects
@@SPACEDESIGNWAREHOUSE thanks mate! You’re AWESOME 😎. I’ve subscribed and will be delighted to hear from this project update! Great way to make mining “somehow more sustainable”.
@@SPACEDESIGNWAREHOUSE I know. Unfortunately, crypto mining isn't as popular here (likely due to the cost) but still feasible. It just makes the sort of endeavours you're undertaking out of the question here really; we also don't really have pools in our gardens haha! P.S. I am a website developer so maybe you need a helping hand in that area of business!
Can you draw a diagram of the pipes in the paper and put at the end of this video? Because it's confusing to see in the video 4:59 how it turned out, because now there are 2 buckets. Great video, you can now set up a swimming pool heating company. Hahaha
The pipes got a little crazy because of how small the space is but yes I can make a diagram. I’ll have to upload it in the members area or in the discord, TH-cam doesn’t let you add on to videos
The metric is much appreciated. Couldn't imagine living in a country where the room temperature could boil ethanol at sea-level barometric pressure (on paper with some common unit oversight).
I got mine from polycase.com but it turned out they weren’t water tight and I had to plug holes with bolts and viton washers. So that may not be the best route
Awesome video love it! Curious about two things. I know you mentioned that the pump was approved via Engineered Fluids but I can't seem to find it. Mind sharing the model number or link? Also curious about the use of the radiator? It was hard to see how it tied in the final design. Was it intended to augment the heat exchanger or was it for an other purpose? Thanks again and great video. Wish I could make these!
For sure! And actually the pump is right there in the description; here's the link: bit.ly/3tIneAn The radiator is a redundant system. So in the event that the heat exchanger pump dies, or something gets clogged- that radiator is big enough to completely cool the whole system by itself, and so is the heat exchanger. These machines are too expensive to be thwarted by one part going bad in a home made cooling system.
Well 2022 was kind of a bummer, I keep getting more and more Bitcoin all the time, but the dollar value of my entire account has shrunk over the year! I’m holding though
@@SPACEDESIGNWAREHOUSE next halving and bull run could very possibly put you in the green even with the SATs you get. How much temp change was noticed from running the system vs not. In terms of the pool getting warmer. Was it noticable? If anything it's just over kill cooling for the miners.
@@evanwinegardner4103 Surprisingly YES, the pool was getting warmer! Its a huge amount of water, but a constant stream of hot water does in fact tip the scales. WHat I found out, later, though, was that chlorine and copper brazing dont play nice.. So I had to take the thing apart shortly after making this video otherwise eventually pool water was going to infiltrate the cooling system on the miner side.. You can do the same thing with a stainless steel heat exchanger.
Dude...did you submerged even the RJ45 network connections??? Well, it´s nice to hear you used bitcool. Congrats. I love a video like this, with all the messy things. Thanks for sharing.
is there a reason why you didn't go with the T cap to force air out? just like you did in your previous build. I wonder why did you go for pipe cutting here?
I thought I had bought one and then AFTER I started putting everything together and started filming and it was all happening I realized I bought it in 1” and didn’t have one, and didn’t want to stop everything and go to Home Depot:) I recommend having it!
@@SPACEDESIGNWAREHOUSE Thanks! My march pump is coming. I have it planned to be lower than the tank and installed a ball valve right after a T-cap. I should be able to prime it with no issues.
Excellent video friend. Do you think that using 2 containers, the external one with ice water and the internal one with mineral oil, will serve to keep the asic miners at a good temperature? Thank you
It would keep them at a good temperature until the ice melts. Generally if a container of ice water is sitting next to a tank of 100 degree oil, it will melt the ice and heat up that water tank.
@@SPACEDESIGNWAREHOUSE Friend, yes correct, the idea is to keep the ice in the external container with water constant, look for temperatures close to 20 ºC. Another thing, what disadvantages does oil immersion refrigeration have? Is it true that it affects the cards, and wire?
Iim glad you asked because it turns out the one I got is the wrong thing entirely.. Chlorine eats brazed copper, so you need to find a stainless steel heat exchanger made for pools..
I really thought someone would have invented a bitcoin mining water heater by now... I searched for this in 2016 and there were a few articles suggesting some companies were about to release one but every 6 months or so since then, I've looked again and nothing.
Makes sense, first priority should be heating house/garage, then if you still have too much heat you could heat greenhouse/pool/hot water tank/ maybe floors if you have required pipes. I would love seeing a micro ASIC farm heating all these at the same time, that would make a killer system brilliant piece of engineering.
Agreed, if I lived anywhere but where I do... Florida. Its going to be in the 70's today and we will run AC int he house! But the pool is too cold to get into
It might be cool to us this S19 with hydrocooling from Bitmain. Maybe it could be plugged in directly to the pool pump as long as the pool water wouldn't corrode the innards of the miner. Bitcoin Miner S19 Pro+ Hyd
After all of that mucking around with the tanks and all of the extra cooling liquid used, would it not have been cheaper to use bitcool's tank? I do like DIY but sometimes it is just easier to buy
@@SPACEDESIGNWAREHOUSE 2 unit system for $6500? Their market size is probably going to be 10 people tops. That price level makes no sense at all...depending on the miners you have it would take a year or more of earnings to pay that off before you even factor in the cost of power. People would be much better off just buying a plastic storage shed for their backyard for a few hundred bucks, hooking up an extension cord for power and putting their miner in that...or following in your footsteps and doing it diy.
@@SPACEDESIGNWAREHOUSE 6,500 that is definitely a high entrance point. DIY all the way! Your trial and error videos defiantly have highlighted some of the issues with immersion cooling
How many watts does each ASIC draw? A commercial pool heater is 5000 watts typically. Factor in losses and I bet you need 7500w worth of miners to match the heat rejection capacity of the pool water to the ground, the air, and what the pipes themselves reject into the air for now and into the ground later.
Great job on it all!! I'm enjoying the series! BTW, where are you getting those clear spillover tanks? I didn't see them on the engineering fluids website. Thanks
I have been trying to build an immersion cooling setup at home for some time now, and just the other day i found your first two videos, i was thrilled that someone documented the process fully, since i also have a pool, i plan on doing a similar setup. though i would also ask, due to summer heating the pool, how hot fo you believe your pool will eventually get?
I wonder that, too!!! I was just looking into the effects of chlorine on copper though and it’s maybe a little iffy to keep the heat exchanger running when everything gets really hot. If they DO fail, they do so by mixing the fluids and that would be catastrophic :(
@@SPACEDESIGNWAREHOUSE definitely a very bad scenario. my personal plan was to do somewhat similar to the setup in your second video, with my s19 inside my garage, but the tubing is piped through the wall, outside, to the radiator and a fan mounted on the side of the house, that way heat goes out, and miner stays inside. though with payouts being down by almost 50% for me, if it keeps up I will end up not even breaking even with electrical, so gonna hold off for a bit on buying the immersion cooling for the moment. hopefully, payout rates go back up at some point, still new to using ASICs.
Do you have a link for the 1/2" MNPT port? Having a hard time finding one. Great job on the videos, appreciate you sharing your knowledge and experience!
They’re not the only ones doing testing to see what’s best:) They’re probably right though. I wanted to see if I could hear the pool, and it’s looking like I can!
Well, the electricity is nearly 100% converted to heat. So if you consider a hot plate takes about 1000 watts, this would be like three hot plates running continuously. So 150 liters would heat up in 2 hours and 27 minutes according to this calculator? bloglocation.com/art/water-heating-calculator-for-time-energy-power
That would be a smart thing to add to the system. I dont have anything for that, but there are things that can alert you if the power stops at a particular breaker.
Hi!! I´m from Argentina, and i will like to know about the material of the tank. I´m doing one my self and i dont know about which material can i use!! if you can help me, i will be very gratefull. i really like your channel
Hey Patricio! This tank is made out of acrylic. But I didn’t put it together myself. I think steel would be WAYYYY easier to work with. There’s certainly no reason it needs to be seethrough.
Not at this scale. When you have a bigger system with like 6-10 machines then the electricity from the fans not running is greater than the electricity running pumps. But that’s not the reason to do this. It’s for temperature stability, overclocking and no more noise or filters
I've been subbed to your channel since the first vid and really enjoy the content. I have a ? For you tho. Based on the daily profit your sj19s are making a profit after power of 26 dollars a day. I am curious as to why you decided to go with a bitcoin miner instead of more gpus. Was it a space concern?. I only say this because even with scalper prices you could get at least 30 or more 1660ti gpus with the same 15k the bitcoin miner cost. Those make after power even on nice hash around 1.20 per day so the 30 would make 36 per day instead of the 26 per day. If I am missing something here please let me know. I was just curious is all. I've got a decent size gpu farm and have been running the numbers as I'd like to move into the bitcoin miners more but I can't seem to find one that can beat the daily profit on the investment that gpus offer atm
The Bitcoin miners make less profit but they should make profit for longer. We all know the impending doom of ETH2.0 and the uncertainty it will bring for profits afterwards.
I imagine that’s not too difficult to set up in the future.. I have 6 S19j pros total, so this is all a path towards getting them all immersion cooled. The final system should probably have something like that.
Next time use pex. No need for angle fittings and still good with high temps. Bitmain made a liquid cooled miner. Maybe you can modify your new ones with heatsink from those.
David Sundin from Engineered Fluids says that PEX is actually “cross-linked polyethylene”, or XLPE. He doesnt recommend it for use with an immersion system because although XLPE is compatible at lower temps, it softens in the presence of hydrocarbons at temps above 140F, which is right in the middle of the temp band where you’re going to be.
@@SPACEDESIGNWAREHOUSE Pex can do over 200F with no/low pressure and 180F under typical plumbing pressures. They test with chlorine to 140F(the max for the test). Since you don't have high water pressure, I would think it would be fine. That CPVC(or glue used) is like a ticking clock, it will degrade over time and give you a bad day. If you get higher temps then use flexible copper or stainless steel like solar water heating suppliers sell.
Hey man, why don’t you look into pump recirculating equipment for home brewing. Looks like you did a bit too much work for this. You could have gotten a custom copper pipe and ran it around the miner with the Bitcool filled in and ran the pump from the pool into the tank and back it to the pool for a fresh steam of cool water
Like just a bare copper pipe but no heat exchanger or radiator? These are pulling close to 7000 watts of power with most of that becoming heat. That’s quite a lot of heat to get rid of!
@@SPACEDESIGNWAREHOUSE brewing equipment such as an immersion chiller or counter flow chiller is taking water from 212 to 70 degrees within mins. You can probably engineer a double chiller. Use the bitcool with the miner, then in a different Vat, have some glycol that chills the bitcool, and then another chiller that runs to your pool. These chillers work wonders and they are fast. How hot does your bitcool get just by itself with no cooling? th-cam.com/video/S1CxyKL7sUg/w-d-xo.html
@@bg1n with no cooling it would just get up to 90C and shut itself off within about a minute. It needs to be cooling constantly at something like 14,000BTU
Well thats more dificult because once your water heater tank is hot, it will shut off.. but the bitcoin miners never shut off - the water would just get hotter and hotter forever.
@@SPACEDESIGNWAREHOUSE yep I understand, so you’ll need a more “smart” set-up which will “choose” between the home tank and the radiator cooling your liquids depending on how hot your home tank is at all times. I actually see this as a potential MAJOR disrupter in basically most of heating solutions, given that innovators like yourself can see it’s probability. Thanks for your help again!

These radiators are sufficient to keep two miners cool, but you have to be really careful about the flow of the coolant up through the machines. If your nozzle is positioned in such a way where the flow is biased to one side, it will cool one miner MUCH more than the other and not work well enough.. Engineered Fluids uses flow plates to make this work - I just had to play around with the nozzle position a bunch; but this radiator can handle both units without the pool
@@SPACEDESIGNWAREHOUSE wow, even with the overclock to 125gh? Either way, super cool videos! looking forward to seeing what's next. Not 100% sure what a flow plate is, but I'll head on over to the great google and see what I can dig up.
If nothing else, you are an amazing scientist.
What tank are you using/materials? These look like electrical control cabinets ?
Thanks for all the awesome videos, love the honesty of them showing all the issues etc
Thats right! Well, the bottom one is an electrical control cabinet. The top one is a truck tool box. They are both steel
GREAT project! Any updates on the stainless steel heat exchanger ?
I got super backed up with projects and real life and I slapped two radiators on those lines and that’s how it’s been running for the last month. But I’ve got the thing!! Starting in a couple weeks I’ll stop traveling and get back to these projects
@@SPACEDESIGNWAREHOUSE thanks mate! You’re AWESOME 😎. I’ve subscribed and will be delighted to hear from this project update! Great way to make mining “somehow more sustainable”.
Super cool! Loving your videos. Reach out if you're ever in Sarasota!
Very cool man. Can't wait to see the next step of the journey.
I love this dude, I wish I could even just help with these neat projects you're doing. Im already at my capacity renting a place with a few GPUs :(
What state do you live in, Tom Penny!?
@@SPACEDESIGNWAREHOUSE I live in the United Kingdom mate! In the county of Oxfordshire :)
@@SPACEDESIGNWAREHOUSE Where power costs 28p p/kwh (38c)
@@SnoozeyP30 WOW!! Well shoot..
@@SPACEDESIGNWAREHOUSE I know. Unfortunately, crypto mining isn't as popular here (likely due to the cost) but still feasible. It just makes the sort of endeavours you're undertaking out of the question here really; we also don't really have pools in our gardens haha!
P.S. I am a website developer so maybe you need a helping hand in that area of business!
Two observations:
1) Space Design Warehouse = MacGyver of ASIC mining.
2) She-Shed is now the SHA[256]-Shed.
I applaud your ingenuity.
I appreciate that!
Can you draw a diagram of the pipes in the paper and put at the end of this video? Because it's confusing to see in the video 4:59 how it turned out, because now there are 2 buckets. Great video, you can now set up a swimming pool heating company. Hahaha
The pipes got a little crazy because of how small the space is but yes I can make a diagram. I’ll have to upload it in the members area or in the discord, TH-cam doesn’t let you add on to videos
The metric is much appreciated. Couldn't imagine living in a country where the room temperature could boil ethanol at sea-level barometric pressure (on paper with some common unit oversight).
Awesome build. Can't believe you tried to put your mouth on the pipe lol. Could you link your 2 toolboxes that you used?
So I ordered the pump and rad - thanks - any tips on finding the water tight metal boxes?
I got mine from polycase.com but it turned out they weren’t water tight and I had to plug holes with bolts and viton washers. So that may not be the best route
4:50 when you said the brazed exchanger exits the oil a "little bit" cooler, does that mean such a channel alone won't be enough to cool an S19?
A heat exchanger alone WOULD be enough to cool an s19
Is there a company that makes containers for immersion?
Awesome video love it! Curious about two things. I know you mentioned that the pump was approved via Engineered Fluids but I can't seem to find it. Mind sharing the model number or link? Also curious about the use of the radiator? It was hard to see how it tied in the final design. Was it intended to augment the heat exchanger or was it for an other purpose? Thanks again and great video. Wish I could make these!
For sure! And actually the pump is right there in the description; here's the link: bit.ly/3tIneAn
The radiator is a redundant system. So in the event that the heat exchanger pump dies, or something gets clogged- that radiator is big enough to completely cool the whole system by itself, and so is the heat exchanger. These machines are too expensive to be thwarted by one part going bad in a home made cooling system.
@@SPACEDESIGNWAREHOUSE Good idea on the redundancy! Thanks for the reply and the link!
dude how do you only have 13k subs?? you make great content overall
Should of done a bad ass video of the system going with music and slow-motion real of only the fluid pumping
I subbed just because you did this. Well done. This is pretty genius. Funny thing will be if the crypto earned will have paid for it all
Well 2022 was kind of a bummer, I keep getting more and more Bitcoin all the time, but the dollar value of my entire account has shrunk over the year! I’m holding though
@@SPACEDESIGNWAREHOUSE next halving and bull run could very possibly put you in the green even with the SATs you get.
How much temp change was noticed from running the system vs not. In terms of the pool getting warmer. Was it noticable?
If anything it's just over kill cooling for the miners.
@@evanwinegardner4103 Surprisingly YES, the pool was getting warmer! Its a huge amount of water, but a constant stream of hot water does in fact tip the scales. WHat I found out, later, though, was that chlorine and copper brazing dont play nice.. So I had to take the thing apart shortly after making this video otherwise eventually pool water was going to infiltrate the cooling system on the miner side.. You can do the same thing with a stainless steel heat exchanger.
Dude...did you submerged even the RJ45 network connections??? Well, it´s nice to hear you used bitcool. Congrats. I love a video like this, with all the messy things. Thanks for sharing.
Yes I did! With bitcool, its like theyre in the air as far as they know!
is there a reason why you didn't go with the T cap to force air out? just like you did in your previous build. I wonder why did you go for pipe cutting here?
I thought I had bought one and then AFTER I started putting everything together and started filming and it was all happening I realized I bought it in 1” and didn’t have one, and didn’t want to stop everything and go to Home Depot:)
I recommend having it!
@@SPACEDESIGNWAREHOUSE Thanks! My march pump is coming. I have it planned to be lower than the tank and installed a ball valve right after a T-cap. I should be able to prime it with no issues.
how much are you making? say at BTC 42K, just interested
At BTC 42k I’m making about $130/day on six S19J Pro
@@SPACEDESIGNWAREHOUSE Is this after paying utility bills or before? Thanks in advance!
Any idea what the energy/Kwh draw is on the electric to run it?
What an adventure !!! Love it !
if sugars or starch would be mixed in that mineral oil, would that affect the cooling properties of the fluid
Anything mixed in would have SOME effect, but why sugar and starch? Also, there is no mineral oil in this system.
Amazing video again! Loved it!
Wow amazing. Subbed.
Excellent video friend. Do you think that using 2 containers, the external one with ice water and the internal one with mineral oil, will serve to keep the asic miners at a good temperature? Thank you
It would keep them at a good temperature until the ice melts. Generally if a container of ice water is sitting next to a tank of 100 degree oil, it will melt the ice and heat up that water tank.
@@SPACEDESIGNWAREHOUSE Friend, yes correct, the idea is to keep the ice in the external container with water constant, look for temperatures close to 20 ºC. Another thing, what disadvantages does oil immersion refrigeration have? Is it true that it affects the cards, and wire?
@@yeanpadron7020 if you use electrocool instead of Bitcool, it will not affect the wires and cards. But it’s rather expensive.
Interesting Video, which heat exchanger do you use for 2pcs S19? 160KW 40 plates? I would like to build the same.
Iim glad you asked because it turns out the one I got is the wrong thing entirely.. Chlorine eats brazed copper, so you need to find a stainless steel heat exchanger made for pools..
I really thought someone would have invented a bitcoin mining water heater by now... I searched for this in 2016 and there were a few articles suggesting some companies were about to release one but every 6 months or so since then, I've looked again and nothing.
bro your videos are amazing
bro, getting comments like this on my videos is amazing.
You know I gotta do it.... FOR THE ALGORITHM.
Your sacrifice for the cause is appreciated
Makes sense, first priority should be heating house/garage, then if you still have too much heat you could heat greenhouse/pool/hot water tank/ maybe floors if you have required pipes. I would love seeing a micro ASIC farm heating all these at the same time, that would make a killer system brilliant piece of engineering.
Agreed, if I lived anywhere but where I do... Florida. Its going to be in the 70's today and we will run AC int he house! But the pool is too cold to get into
@@SPACEDESIGNWAREHOUSE somewhat same here in texas was 68 2-3 days ago, though it is 28 now. would be nice in the winter, just not so much summer.
Hey bro. Can i ask one quistion. Will you still keep mining with the oil cooling system?
It might be cool to us this S19 with hydrocooling from Bitmain. Maybe it could be plugged in directly to the pool pump as long as the pool water wouldn't corrode the innards of the miner.
Bitcoin Miner S19 Pro+ Hyd
Love watching this project! So fascinating!
After all of that mucking around with the tanks and all of the extra cooling liquid used, would it not have been cheaper to use bitcool's tank?
I do like DIY but sometimes it is just easier to buy
Easier, yes, but cheaper, probably not. They’re going to be offering a two unit system for about $6500
@@SPACEDESIGNWAREHOUSE 2 unit system for $6500? Their market size is probably going to be 10 people tops. That price level makes no sense at all...depending on the miners you have it would take a year or more of earnings to pay that off before you even factor in the cost of power. People would be much better off just buying a plastic storage shed for their backyard for a few hundred bucks, hooking up an extension cord for power and putting their miner in that...or following in your footsteps and doing it diy.
@@SPACEDESIGNWAREHOUSE 6,500 that is definitely a high entrance point. DIY all the way! Your trial and error videos defiantly have highlighted some of the issues with immersion cooling
Funny, descriptive and educational- awesome!
Are you going to the Rolex 24 or 12 hrs of Sebring this year?
I'll be at Sebring this year.. Im not sure if Im free during the Rolex!
How were you able to appropriately size a heat exchanger per your setup or kw?
By oversizing it with two pretty big radiators, each 24”x24” with three loops inside them.
How many watts does each ASIC draw? A commercial pool heater is 5000 watts typically. Factor in losses and I bet you need 7500w worth of miners to match the heat rejection capacity of the pool water to the ground, the air, and what the pipes themselves reject into the air for now and into the ground later.
Each miner draws about 3500 watts so we’re close to that!!
Great job on it all!! I'm enjoying the series! BTW, where are you getting those clear spillover tanks? I didn't see them on the engineering fluids website. Thanks
They are test tanks that I don’t think they’re selling yet. They intend to start selling them this year
@@SPACEDESIGNWAREHOUSE Awesome, I'll be on the lookout for when they start selling them 👍
This is great 👏🏼👏🏼👏🏼
Hey Henry!
@@SPACEDESIGNWAREHOUSE sup nick 😎
Ive been trying to figure out how to do a Immersion cooling / in floor heating setup
Let me know if you end up prototyping anything. Been looking into this as well
Do you have a link to the heat exchanger and even the radiator you used in your other video?
amzn.to/3Imp0ew radiator... amzn.to/3GKje5L heat exchanger!
@@SPACEDESIGNWAREHOUSE LENEND :)
I have been trying to build an immersion cooling setup at home for some time now, and just the other day i found your first two videos, i was thrilled that someone documented the process fully, since i also have a pool, i plan on doing a similar setup. though i would also ask, due to summer heating the pool, how hot fo you believe your pool will eventually get?
I wonder that, too!!! I was just looking into the effects of chlorine on copper though and it’s maybe a little iffy to keep the heat exchanger running when everything gets really hot. If they DO fail, they do so by mixing the fluids and that would be catastrophic :(
@@SPACEDESIGNWAREHOUSE definitely a very bad scenario. my personal plan was to do somewhat similar to the setup in your second video, with my s19 inside my garage, but the tubing is piped through the wall, outside, to the radiator and a fan mounted on the side of the house, that way heat goes out, and miner stays inside. though with payouts being down by almost 50% for me, if it keeps up I will end up not even breaking even with electrical, so gonna hold off for a bit on buying the immersion cooling for the moment. hopefully, payout rates go back up at some point, still new to using ASICs.
hell yes!
Do you have a link for the 1/2" MNPT port? Having a hard time finding one.
Great job on the videos, appreciate you sharing your knowledge and experience!
Here you go! Make sure to swap out the rubber for viton or nitrile.. amzn.to/3tHtFUd
I thought engendered fluids says it's best to run a closed single loop dry cooler
They’re not the only ones doing testing to see what’s best:) They’re probably right though. I wanted to see if I could hear the pool, and it’s looking like I can!
how fast 3,2kwh asic mine will heat 150l boiler water to 65degress, for the rest of energy I want to use for home heating by drycooler
Well, the electricity is nearly 100% converted to heat. So if you consider a hot plate takes about 1000 watts, this would be like three hot plates running continuously. So 150 liters would heat up in 2 hours and 27 minutes according to this calculator?

Any form of alerting/notification if a pump dies?
That would be a smart thing to add to the system. I dont have anything for that, but there are things that can alert you if the power stops at a particular breaker.
Hi!! I´m from Argentina, and i will like to know about the material of the tank. I´m doing one my self and i dont know about which material can i use!! if you can help me, i will be very gratefull. i really like your channel
Hey Patricio! This tank is made out of acrylic. But I didn’t put it together myself. I think steel would be WAYYYY easier to work with. There’s certainly no reason it needs to be seethrough.
This is genius
do you save any money in electricity? ldo you consume less wattage by cooling the miners this way
Not at this scale. When you have a bigger system with like 6-10 machines then the electricity from the fans not running is greater than the electricity running pumps. But that’s not the reason to do this. It’s for temperature stability, overclocking and no more noise or filters
@@SPACEDESIGNWAREHOUSE do you have the dcx cooling oficial page by any chance
I've been subbed to your channel since the first vid and really enjoy the content.
I have a ? For you tho.
Based on the daily profit your sj19s are making a profit after power of 26 dollars a day. I am curious as to why you decided to go with a bitcoin miner instead of more gpus. Was it a space concern?.
I only say this because even with scalper prices you could get at least 30 or more 1660ti gpus with the same 15k the bitcoin miner cost. Those make after power even on nice hash around 1.20 per day so the 30 would make 36 per day instead of the 26 per day.
If I am missing something here please let me know. I was just curious is all.
I've got a decent size gpu farm and have been running the numbers as I'd like to move into the bitcoin miners more but I can't seem to find one that can beat the daily profit on the investment that gpus offer atm
The Bitcoin miners make less profit but they should make profit for longer. We all know the impending doom of ETH2.0 and the uncertainty it will bring for profits afterwards.
Will you try to modulate the system? So when the pool gets to your desired temperature it will automatically shift to the air exchanger?
I imagine that’s not too difficult to set up in the future.. I have 6 S19j pros total, so this is all a path towards getting them all immersion cooled. The final system should probably have something like that.
I would bet that the heat rejection of the pool water to the ground and air far outpaces the miners ability to generate heat at least in winter.
This is awesome, but I must point out that your shed is NOT a she shed. No woman in her right mind would claim that mess! 😜
Next time use pex. No need for angle fittings and still good with high temps. Bitmain made a liquid cooled miner. Maybe you can modify your new ones with heatsink from those.
David Sundin from Engineered Fluids says that PEX is actually “cross-linked polyethylene”, or XLPE. He doesnt recommend it for use with an immersion system because although XLPE is compatible at lower temps, it softens in the presence of hydrocarbons at temps above 140F, which is right in the middle of the temp band where you’re going to be.
@@SPACEDESIGNWAREHOUSE Pex can do over 200F with no/low pressure and 180F under typical plumbing pressures. They test with chlorine to 140F(the max for the test). Since you don't have high water pressure, I would think it would be fine. That CPVC(or glue used) is like a ticking clock, it will degrade over time and give you a bad day. If you get higher temps then use flexible copper or stainless steel like solar water heating suppliers sell.
I like it.
Hey man, why don’t you look into pump recirculating equipment for home brewing. Looks like you did a bit too much work for this. You could have gotten a custom copper pipe and ran it around the miner with the Bitcool filled in and ran the pump from the pool into the tank and back it to the pool for a fresh steam of cool water
Like just a bare copper pipe but no heat exchanger or radiator?
These are pulling close to 7000 watts of power with most of that becoming heat. That’s quite a lot of heat to get rid of!
@@SPACEDESIGNWAREHOUSE brewing equipment such as an immersion chiller or counter flow chiller is taking water from 212 to 70 degrees within mins. You can probably engineer a double chiller. Use the bitcool with the miner, then in a different Vat, have some glycol that chills the bitcool, and then another chiller that runs to your pool.
These chillers work wonders and they are fast. How hot does your bitcool get just by itself with no cooling?
th-cam.com/video/S1CxyKL7sUg/w-d-xo.html
@@bg1n with no cooling it would just get up to 90C and shut itself off within about a minute. It needs to be cooling constantly at something like 14,000BTU
How hard will it be to use that cool heat exchanger for hot water for your HOME?
Well thats more dificult because once your water heater tank is hot, it will shut off.. but the bitcoin miners never shut off - the water would just get hotter and hotter forever.
@@SPACEDESIGNWAREHOUSE yep I understand, so you’ll need a more “smart” set-up which will “choose” between the home tank and the radiator cooling your liquids depending on how hot your home tank is at all times. I actually see this as a potential MAJOR disrupter in basically most of heating solutions, given that innovators like yourself can see it’s probability. Thanks for your help again!
