My set-up to heat house using bitmain S7 (UPDATE 03JAN2016)

[DrG]

Older (read broken in) miners are safer to use if the exhaust is going to be inhaled directly.  If the heat is exchanged then there is no issue.

Newer miners (or any electronics for that matter) will give off more volatile chemicals when heated so consider that if you want to heat your house.  I won't say they'll cause cancer at a certainty but they are definitely not safe at higher concentrations.

definitely not safe

BS WARNING ! BS WARNING ! BS WARNING ! BS WARNING ! BS WARNING !
So how many deaths and incurable diseases per million population would you expect from fumes from an S7 and how does that compare to the fumes from other heat sources such as a new fridge or a new microwave oven or a new coal fire ?

hey guys...i have a question about this s7 antminer

I have ordered 2 from bitmain batch9 starting to deliver on 20 Jan,SO my question is :

Can you sleep in the same room with 2 s7 antminers working ? how loud are they realy?

[whizz94]

I don't have any S7; only the S1 which is a two year older design, so take this with a pinch of salt and let us know how you get on.
The S7 differs from the S1 in having push-pull twin fans, which should make it quieter for a given heat output, tri blade design (smaller fins) which should necessitate faster airflow, and 1300 Watts power in place of 360 Watts.  That is, I'd expect it to sound like too much of a jet turbine to try to sleep next to it.  It would be safe, just noisy.

On my S1, fans typically end up at 2000 rpm in normal weather increasing to 3600 rpm in warm conditions.  It is only quieter than that in the first half hour before it has warmed up or if underclocked to 2/3 of its design hashing rate.

I have slept in the same room as my running S1 without problem but usually prefer to shut the door on it because it is a little louder than the cooling fans of a server.

The other consideration is what to do with 2.6kW of heat, which is about the same as an electric oven.  Those tend to have a vent bashed through the brickwork and still make the room rather warm if used for a few hours.

They are loud. Small jet engine. That insulated duct I linked has a bigger version (8x25, 10x25, 12x25). I can't remember which works perfect but Philip listed one that you can stick inside which will reduce the noise incredibly.

Which PSUs are you going to use? If you use the 1300 G2 that thing is quiet but if you use the 2880 ones they are too loud. The 4k package from finsky is quiet as heck but needs 208V + outlet, the 1300 G@ EVGA only needs 120v outlet.

If you want a really quiet miner the Avalon 4.1 is quiet and can heat a room nicely. You can find them on Ebay or the marketplace section. They only do 1th/s but they are WAY quieter than the S5 which is comparable.

you know the thing is that this is the main problem I have made the order for 2 PSU 1600 bitmain stuff for 140$ each,im guessing those are gonna be louder that the miner itself:)?
does any one know for sure?please would be realy helpfull

Just as loud as the miner. Not much to quiet both unless you stick in that insulated duct but even then that is lots of noise

shit...ok thanks for you support guys !appreciate it

I just found your post, really nice setup! I have been working on a similar project and loving the free heat off of it.

Where are your miners pulling the air from? Are you basically circulating inside house air or pulling fresh outside air?

Air is being pulled from inside the garage. I have vents on the far wall that let the air inside the garage. Stays around 45 F inside the garage at all times and during the summer doesn't exceed 55 F. Its a 2 car garage with room for my workbench and storage. So pretty big area to pull air from.

So the air is coming from the house? I am asking because it would be more efficient to pull from the house vs the out side air.

Air from the garage, 2 vents on far wall allowed air to move freely in garage

Pulling the air from inside the house, to heat a house. Wouldn't that make the air quality poor? I guess there is a reason why we have vents?

thats scary actually.. air from you cars exhaust and engine fluids being heated/burned etc

you must be taking precautions or you wouldnt be alive to post.. or never run engines (the obvious answer)

yeah the heating that is done from device like asic is not healthy at all, there are case of guy running his miners inside is room where he sleep, and he had health problem at the end

That has nothing to do with air quality, but with temperature. The story is here. cryptotore was solely talking about air quality. That being said, that can probably be overcome with air filters, which are probably in place given the setup OP has

No one would be alive if they ran there car with the garage door shut. Not sure if I should even answer this obvious question.

I am still unclear by their question. I will try to break down barney style.

free flowing air (from the outside, not being pulled just flows in naturally through vents) comes into the garage from 2 vents. This air circulates in garage and the miners pull from this air. The air is from the outside which is cold (45 F currently) which keeps the miners running below 50 C. The miners blow into my HVAC system which is already supplied with air filters.

Please read previous comments. The air blow is not any more dangerous/not dangerous than the fan blows from a microwave, computer... etc. Think common sense please.

I love the ingenuity and creativeness that you have put into this project.  Really embracing what bitcoin is.  I also really like the idea and have a few questions.

It seems like you have been running for a bit, have you noticed you furnace having to turn on at all? Or is the heat from the miners enough to heat your entire house?
If you don't mind me asking, how big of a house are you heating?
You said you had to cut into the ducts, if you ever decided to stop doing this (say summer) or sold the house, is that something that is easily fixed by just putting a piece of metal over where you cut in?

Thanks for the answers, like I said, I really like the project and could see myself doing something similar.
