Topic: The winter mining setup - page 2. (Read 4082 times)

I have 3 miners running in the garage.  They are ducted from the exhaust and dump directly outside.   
Now that outdoor temps are 50-60 during the day, 30-40F overnight, i unhooked the exhaust duct off one unit and turned it facing into the garage. Garage is now holding a steady 72°.

The garage footprint is about half the house, with all 4 bedrooms above the garage area. Unfortunately, I don't have forced air HVAC, so I can't really spread the heat throughout the house.  But hoping the warmer garage will help overall house heating. With a "bleed-out" effect. 

The garage is not temp controlled like the rest of the house (split level) and in the deep winter can get down to another 45-50°. 

I currently have a houseguest living temporarily in the other half of the basement.  If/when she moves out, I can open the interior garage door and basement door, and simply run a box fan to move the heat upstairs. 

Another month or so, and temps may allow un-ducting of a second miner.

*blowing sound* Time to dust off the old basement and offset those damn winter utility bills again. I've taken some of the lessons from last season, and applied my sound dampening from the summer mining setup.

I present my test of 3 m10's in my new and improved Winter set up for the basement. Mineral wool insulation both intake and exhaust side. Intake has screen mesh wrapped around it to prevent any insulation being sucked into the fans should it degrade or flake off. Right now 2 30 amp circuits feeding the 3 m10's, and going to let it run another day or so to see how it fares. 2 shelving units sans shelves laying flat for the tunnels, and 1 upright with a shelf to create the seal and balance routers and PDU's as necessary. Animals strictly forbidden from entering the space, gave them a firm talking to.

So far the sound dampening is amazing compared to last year. I couldn't hear any of the fans upstairs over my general background furnace fan noise, so that's huge. This gives me hope that I will be able to put the M20s in there. plenty of space left, and this way I can downclock my 741's super low and place them just on the concrete slab near the furnace to do their part. That or drop them off at my buddies winter shack, but unless I'm going there anyways the gas isn't worth it. I'll get some sound meter readings at some point but this was the end of 3 late evenings of planning, placing, re-planning then just going for it. Oh yeah big difference is that I am exhausting towards the stone wall, atm I just have a larger baton of mineral wool placed against it to prevent degrading the mortar, but will place more. This has redirected a lot of sound and heat from where I have my PC set up downstairs. Here's some photos enjoy.One thing I did forget that I believe will help as well is placing a fitted piece of 1/2" rigid insulation under the miners themselves. It will raise them up a bit and reduce some of the sound I hear downstairs by taking them off the metal rack.

Well I guess the first day of spring is as good as any to call my Winter mining Dead for the season. Well at least on life support. Currently I am running the 2 M10's in the basement with the 741's offline. Our temperatures just haven't dropped off enough.

In the evening I have played with cycling 2 741's on for a couple hours to help with the evening cool off, but haven't in a couple days. Now the reason I am running such a silly way and not just my 741's and the M10's in the garage is that in short I can't lift 1 arm enough to set up my garage for the spring-fall season.    
I am slowly gaining my mobility back so hopefully tomorrow or the next day I'll get things moved around and can get back to free hash inside for another couple weeks. I figure I'll be between 1 and 3 741's for a few weeks while we hover between -5 and 7 Celsius.

I will definitely update next year when the M10's move back in the house with ideally with a nicely insulated box to cut some of that noise down. Worst case they can run low power mode.

Edit: July 10

I am locking this thread until the fall when I move some miners inside. Maybe even a few other cool locations who knows. For more see what I'm up to this summer. Summer Mining

Tons actually. I have been essentially pumping ~8 kw of heat into my basement directly in the path of air recirculation. It's funny you asked this today as I had planned a little update. We've rolled into some very warm early March temps of about -2C highs in the day. Without the furnace kicking on my house was pushing 23C, that's with the furnace S/P at around 18C.

Needless to say I had to back off the M10's a little, I started with low power mode on both units but was able to put the underperformer back up to normal power mode.

I am hoping it cools off a little though, but it is nice to know that so early into the spring season I am already taking my furnace right out of the equation, and still getting ~80TH from what's in the house.

Thanks Haggs.

The heater was the last thing I spoke to Canaan about and  Steven did say it has no certifications for international sales. I don't think it will ever be sold outside China as they don't have faith in it having enough demand for adoption outside of China.


I personally wouldn't set up with liquid cooled. Its a neat idea but not ideal for me for a few reasons.

Added cost and care requirements
I can build a suitable soundproofing alternative

I did however discuss with a guy one time something similar. He wanted to use his miners to heat his water. My suggestion was to use an old radiator (he had multiple from old homes and cars). Same concept to remove heat.

I tried to get one for a review, but they say that it is a mainland China-only product at the moment. I think that the regulations and approvals may be the issue with the international sales.

Cool setup ST.

For the noise issue plunge miner in dielectric fluid but for the next part I wonder how to make an air exchange to get hot air, at least enough hot air to warm a room.

You need to have an update firmware to handle the fan issue.

This Canaan Mining Warmer  is great idea, I wonder how it works, do you have more inputs HagssFIN  ?

Anyway Steamtyme this is a good idea, well done.

Way to rub it in.


I legitimately can run all my miners in the house until the end of April especially if I go low power on the m10's. Now into May I will move the m10's to their summer home in the garage. Come the end of May my 741's will be tucked into their dark boxes where it all began. That's just until next winter maybe.

I have been counteracting the profitability issue by upgrading to the M10's; especially with the same free electricity offset of the basement set up. I will probably grab 2 or 3 more to run through the summer bringing me up to 4 or 5.  This will decide whether or not my 741's see the light of day in my home again. This will be a repeat going forward as long as I can make it happen.

I don't know in which country you reside, but here in Greece it starts to get summer-ish!
Even if Bitcoin doesn't crash any lower, I believe your miner will become unprofitable soon, any plans to counter that?
Maybe use water cooling and create a sauna? Then if Bitcoin crashes even lower you can start renting your sauna for money!

The life of cryptowarriors has become harsh, huh?

So below you can see how the beginning of the migration into the home for he M10's on the left. The right is the temporary permanent setup that has appeased the wife so far.



In the current setup I found that having the overhang of in this case the 1/2 inch rigid, definitely helped with the noise above. It just forced the sound to bounce down a bit more before being unleashed on the floorboards above. i'm currently playing with some designs for a build that I can use for years to come. It's just down to the dimensions at this point.

You can see I played with some of my left over 6" mineral wool insulation from my home renos. The difference in sound directly above was amazing so I got to thinking of a build using this as my main sound barrier for everything past the miner exhaust. On the intake side it will be the same, but lined with either with white fire blanket or a lightweight thermal roll cut and stapled. It's really only three to prevent the mineral wool fibres from entering the miner.Now for the unveiling of what I try to forget I've been breathing for 2 winters. Still shaking my head at the thought of it, stupid me thinking they would have lined the joists/floorboards with tin as well.

The top image was in the main air return to the furnace, now acting as the main air return to the basement. This has since been isolated to the right, to prevent air flowing through the ramainder of that patch until I clear the family out to yank it all down. The left is the air return at the base of my main level stairs and front door. the bottom 2 are where I opened up to create return lines to the furnace, these are in the same area as the miners, on the side they exhaust towards.



So far I'm pleased with how this year has gone, but to extend this as long as possible I need to make a few adjustments. I've noticed on our few days of -12C that the basement gets warm. Nothing severe but the fans definitely work harder and I notice them more through the day, over the family noises. It's mostly because I'm listening for it, but best to get ahead of these things.

pictures?

please

I would hope that if they are building them with people residing there that they used sound dampening materials and ducting. Otherwise I'm not sure it would be worth it, especially if the entire home is heated by miners.

I'm purely guessing, but I would have to assume that my rigs are cutting the load from my heating elements by around 25%, the offset is my furnace fan is on all the time to even things out.

Now if you do not mind editing your post to match this:


Everything I removed was off-topic for this board and thread. IF you don't remove it your post will be deleted by MODS, as it appears you may be shilling this fantastical mining APP.

I think you missed the premise of the thread.

I am using my mining to supplement my winter heating requirements. So it is definitely profitable for me to run any equipment that provides a coin of value.

And to the point of mining in general, with low enough electricity costs people are still profitable with some equipment.

To be fair i solved the problem with an old Humidifier

Well I've managed to get the house up to ~90TH/S
2 x M10 units - I jumped on these a few weeks ago, for the purpose of trying to ROI the equipment faster by offsetting the operating cost in my cold season.
4 741's already in place - These are now at controller setting -1

For this I had to add another 30 amp circuit for the additional miners.

This also required modifying my furnace ducting and switching the fan to continuous. The duct-work was really just opening up the return air on the south side of the run, and opening up the north side of the run near the miner exhaust discharge. This was easy as they were just using tin and the joists as for the run - Which I will be replacing in it's entirety. Upon opening this I found a disgusting crusty mixture of whatever has leaked through the floor boards in the last 20 years.

The M10's in normal mode, have made me consider additional sound proofing. Nothing major probably just play around with the rack I'm using a little more. The hum is noticeable upstairs when the house is quiet, but only I notice when say the TV is on - as I'm always listening for it.

I'll update with pictures soon - So far the wife is happyenoughish with the setup.  

Tapping into nature cold regions can really help make mining more profitable! that will reduce cost on production ann improve the profit

looks nice

Main effect mining in-house during winter is air get super dry.
I had reading of 30% moisture, Arizona desert style.
I dry my clothes around the house to help moisture the place.

If you have moisture issues in your basement, mining help a lot  

A mining operation I was involved with in taiwan was above a bank on a busy street in the city, the miners vented directly out of the slatted window pointed down at the street. Imagine, it’s 35 centigrade in the summer and you’re walking along the street and a great hot blast of air from 300 S9s hits you in the face
