100% Agree!

LOL! Missed that one...the auto-subtitle tool loves to replace miner with minor...and make me sound bad.

Agreed...having some extra room around the miners in the tank is great insurance against any minor changes in miner size and aspect ratio!

Great ideas. With my home layout, the sound of the pump is unnoticeable outside of the room, but if you have your mining setup closer to your living spaces, the hum of the pump could become an issue.

Thanks! Yeah, this was an idea I had for quite a while and I just had to see if I could make it work!

I'm sure you've checked the numbers. I just did a check on mine, out of curiosity. On high heat the dryer system draws 22-23A @ 240v. There is one higher setting, but we never use it. If you've tested, what kind of draw are you seeing with the heating elements "disabled".

Another concept I'm starting to look into is using our cold well water with an exchanger to cool the house before it goes to the irrigation system, which runs for an absurd amount of time each day in the summer (6-8hrs)

@@nickdaniels7593 Good question...so when my dryer is running normally, the current draw is always the same regardless of low/medium/high setting. The difference is duty cycle...at the low and medium settings, the heating element is turned on/off during the drying cycle. When I run the dryer in 'air dry mode', the heating element is off all the time. The difference is 25 amps when element on and 22 amps when element is off. The remaining 3 amps is used by the motor which spins the drum and spins the dryer fan. ...I learned a lot about how dryers work on this project, LOL.

@@nickdaniels7593 that is a fantastic idea! If you have 6-8 hours of water flow, you can run it through a BPHE to cool the miner. Depending on flow rates, you might also be able to use an indirect water heater 'backwards'. The miner constantly dumps its heat to the water heater, but then your irrigation setup cools it down periodically...you might be able to keep your miner running non-stop this way.

Funny...as I've been building, I've thought more and more about how this would/could scale up to a commercial site. If you ever want to collaborate, find me on Telegram and we can talk!

Hi! Yup! I used it in my 120V Immersion build...its a great low-cost option.

@@HBIM_Channel this fall is the time to do it. Been getting hydronics installed spring summer. Will be heating a garage and greenhouse along with a house. Doing a hottub for the summer heat dissipation.

I have only made it through your first 7 or so vids today. Thanks I will try to watch the rest sometime soon.

@@Ironrodpower Awesome to hear! If you have any questions feel free to DM me on telegram

Thanks! More videos to come!

Thanks! Yes...I think there are many opportunities in the home mining space.

Thanks for the comment...and you bring up good, valid points. Previous generations of miners indeed didn't last that long, but as i covered in my miner efficiency episode, the turn-over in miner efficiency is slowing down. For example...the s19 design is going on 4 years old and some models are still very profitable. There are folks using S9s for space heating (see CryptoCloaks' website for examples). I'm very curious how long the latest s21-class miners will stay profitable (maybe > 10 years??)...and who knows what comes after that! We are definitely early and miner heating is currently driven by us hobby-ists who are having fun building and showing proof-of-concept...but if the prevailing trends hold, I think there will be a time down the road where mining-based heating will make a ton of sense over the long run. An average furnace/heat pump costs several thousand dollars...I think there may be a time years from now where a miner-based furnace is just another competitive long-term option to chose from. That's one of the main purposes of the channel...to push the technology and show what could be done. Think the late 1970s in personal computers or 1950-60s with performance add-ons for cars...early tinkering leads to innovation leads to commercially viable products for the average user. We don't know what is possible until we try...and when we learn what is possible, we can build on that and try again 🙂. Some of these ideas will definitely be failures...but some will work. We have to try them all to find out!

What I would add to that is that older miners can be obtained quite cheap. People tend to look at them only in term of bitcoin rewards vs electricity usage. If you count in the heat provided, the whole game is different. Question is not wether you can heat for free. But a lot cheaper than with alter alternatives. But I do agree with a bitcoin miner for heating for your calculations its good to have a horizon of a few years. If you can, invest in solar energy for your home. Will also make businesscase more favourable.

Yeah...and its a great article! Would love to see a new generation of miners developed that ran at hotter temperatures...that would really be revolutionary

Thanks for the kind words...if you're having any questions along the way, let me know...always willing to lend a hand :-)

Thanks for the suggestion...I'm building a second setup for another project (coming soon)...I might try that route!

Sorry to hear...unfortunately, I don't know anything about Kaspa mining or miners...I know on bitcoin miners, you can't run the fans in the fluid and when you remove them, you either need spoofers or an OS update that ignores them...but that's a complete random guess...I'd like to be more help, but know really nothing about how kaspa machines operate.

Great question...my understanding is that Fog Hashing is just re-selling Shell S3 X fluid...but I'd ask them to confirm. If true, you can't get S3 X in small quantities, so you'd have to go back to them to ask for more fluid. As for mixing...I've seen this question posted on other forums and the response has been "Don't know...but it shouldn't be a problem". People generally just buy a single fluid and use it, so info here is scarce. Maybe the thing to do is to take a small amount of both fluids in a small plastic container and microwave/heat it up. If nothing happens, you're good to go...might save you from destroying your entire supply.

You can watch the related episode to get the full story - you need to use immersion cooling fluid

Good question...this is where it gets a little confusing. There is a dev fee (2.5%) for using the OS and a pool fee (2%) for using the pool. When you stay within the Braiins Pool/OS ecosystem, they only drop the pool fee. With a bitmain miner, you have to use an aftermarket OS or you loose up to 20% efficiency gains. By waiving their pool fee, Braiins is pulling more people into their pool. More people = more blocks = more consistent block rewards

True...its tough to understand what's going on...might be a great idea for a new episode! Thanks!

Yes! For my system I didn't deploy the DCX dry cooler, but made my own--its covered in other episodes. I have a mixing valve and temperature switch built into the design so the fluid routes around the dry cooler in the winter (to keep the heat in) and only turn the fan on when the fluid gets hot in the summer.

@@HBIM_Channel yep am making my way through your videos now as my miners aren’t local to me so I need better remote monitoring and management. The pipes froze a couple of months back and now the ICP15 is a write off! Going to upgrade but also want to incorporate the monitoring that you have. Where are those meter displays from? Vosk has them also but not sure if they’re US specific?

@@hewhorocketh Oh no! Sorry to hear about your ICP15...freezing temps can be tough. I got the meters off of Amazon, made by DROK...they are cheap, but so far they have worked fine. www.amazon.com/DROK-80-300V-Voltmeter-Multimeter-Transformer/dp/B01MRZAFAF/ref=sr_1_3_pp?sr=8-3

@@HBIM_Channel that’s really cool. Might be something for the next install. Another thing dcx suggested is putting insulation around the water loop sensor. Would have been nice if that was from factory!

@@HBIM_Channel thanks. I may go down the smart PDU route but the meters are a nice visual real time view without logging into anything. I’m not on site at the farm often.

Great question...cost breakdown will be in the next episode!

Great comment...very obvious you know a bit about hydronic systems 🙂. The way I've designed the system is the main fluid flow is through a larger loop containing the main dry cooler. This loop is sized to prevent deadheading of the pump, or overheating of my miners. This is the 'normal' operation of the system. The garage heater in this video is a lower-resistance bypass of this main loop with the thermostatic valve regulating how much fluid goes through this bypass path. When it is mostly closed, the main loop takes all the flow (normal operation) and when it is open, more fluid goes through the lower resistance bypass which is easier for the pump. In either case, the system keeps fluid flowing and the pump happy (and my miners cool).

Good question...it has the power, so it should work. However, the voltage will likely be a little on the lower side which will limit how hard you can drive the hashboard.

It should be OK. Pex is HDPE...I'm going to use Bitcool and HDPE is listed on their compatibility list as 'recommended'...as long as it doesn't get too hot. I got the idea to use PEX from others in the Immersion space and they've had success using it...but to be honest, this is a new material for me, so I'll be finding out the hard way if it doesn't work. :-(

I agree that's the 'easy' answer...its what I did in my home setup. But, I've had some requests from folks trying to mine in an apartment setting where their electricity is paid for...but they only have 120V outlets. ...just trying to give more folks the ability to stack sats, wherever they live! And...honestly...it's been fun seeing what you can do with 120V power! :-)

Do you mean current flow over the re-built wiring harness going to the control board? Its the same 6 pin control board connection as the S19...and without fans running there should be less current flowing through that connection, right? Did you see overheating at the control board or APW3 side of the harness?

Yes! Look through my more recent episodes, starting at EP20...I'm heating my house, water, and garage with my miners right now...and I've got some cool plans for upcoming episodes!

Good question. DCX says you need the transformer...but 220 AC is 220 AC, so I've read many people stating it should work. The only thing I can think of is the pump has a ground wire. In European 220, that ground wire is at 0V, whereas in the US, it would be at 120V...I'm not an electrical engineer, so I'm not sure if that matters. The transformer box costs about $100, but a new pump can run you $300...so I guess it depends on how much risk you want to take Heating your pool is a great use of miner heat...I've helped a few folks get there and I've got an episode on pool heating...that might help with some planning/details on the pool heater. The tank coming from DCX doesn't have a sealed lid, but the lid overhang and latching mechanism is good...it would take a pretty good storm to get water blown up into the tank. But...given the cost of the fluid and miners, I think it might be worth having some external protection like a cabinet or shelter for the tank. Might be something to plan for, but make the call whether to add additional protection once you get the tank and get a good look at it.

@@HBIM_Channel It would be interesting if you can get a power/load value for just the pumps/cooler alone. By that, I mean measuring that circuit separately from the ASICs. Still need to have the "heat" produced by the ASICS but to be able to measure the pumps and fans to determine the "overhead" for the DCX system.

@@ronwatkins5775 Agreed! I've been meaning to do an episode on 'parasitic losses'...I don't think they are huge, but they aren't zero...would be interesting to see how big they really are for immersion. ...so many ideas, so little time!

25kW...nice!!! Yeah...that should get you pretty close. Make sure to take in yearly variation...long/short days and changing sun angle. Another option is to enter your data into the PVWatts website, which will do the math for you...and is put out by NREL, so it should be somewhat accurate. Its all estimates, though...the goal is to get 'close enough' 🙂
