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

[rockyforever]

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.

1000 squ ft I am heating. It was keeping the house at 68 until temperatures dropped to below 30 F. I now have 3 Avalon 4.1 in the house (2 running in living room and one in guest bedroom), that combo is keeping my house above 72 F which is too warm so I have almost all the windows cracked. I am currently selling 2 of the Avalons since its too warm and temps outside have risen so the 2 S7s will be plenty until summer.

The duct I cut an 8 inch hole. It will be easy to cover with some metal. I can either attach some small screws or special glue for duct work. Its easy fix.

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?

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

the hot air moved by the fan from the asic is not healthy, so yes it has to do with the air, because those part from the asic, when the temperature is high enough they begin to release some particles from the combustion of the pond

not to mention the air moved is full of dust...

Yeah, if you are heating your room with air wich is just going out from a device and filling all the room the air quality will be poor and you'll have headaches or even worse problems with your health.

I think you should make the hot air go through a metal (not heat-insulated) vent tubes and thus they'll heat your room just like radiators do.

You are correct but by just using a high quality 3 inch media filter (whole house filter) you can totally reduce any contaminants by 99% or more. My HVAC engineer friend who has set up hundreds of server rooms in RTP (Research Triangle Park), help me with my setup and this was one of concern's that was addressed.

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 ?

You want me to cite incidence and prevalence of VOC induced disease states?  Why don't you do the homework and post it?

I've bought 2 new fridges in the last 20 years.  I have bought over 500 video cards and 100 miners in just the last 5 - nice troll though

I think he also changed your original text - quoted for advanced trolling technique citing lol.

When I was running my card farm I could definitely smell the chemicals but then again I was pushing them hard to near 90C and had over 100 cards going.  Don't know if I would want to be breathing all that in days on end.

Hm, I haven't thought about that, a high quality filter might solve the problem. IMO that's actually much better than turning the vent tubes into radiators like I proposed. Nice decision. Good luck with your mining!

Came up with a redneck solution instead, has killed the high-pitch sound, so its not a problem anymore.
What I did was basically make sure all the miners get direct cold air from the outside, which made the temps go down. And then the fans didn't have to work as hard anymore, problem solved (for now).

I'm heating my 1800 sq ft home with 4 s7's and it's wonderful. I live in central Canada and it's been a warm winter thus far but I have not had to use my other heat sources yet this year even when temps go down to -29 with windchill. Very simple to get the heat into house.. i run s7's in vertical position and have a 16' flexible tube that moves the heat to upper level where i can store it or use it by simply turning on a fan on.
  The noise of the psu's is a work in progress but have got it down where it is "wife approved" lol

These 4 s7's not only pay for power bill and I get 100% heat recovery.. they pay for my mortgage and bills as well

Do you put 1 S7 in each room so that the heat is distributed evenly? If you put them together and use a distributor, it will incur extra cost.

That's not feasible with the noise, outlets, or wires and he mentioned his wife (I have the same issues). It would be amazing to run a miner in each room but normal house outlets (among all the other things plugged in) isn't an option. Running Ethernet cables to each room, reducing the noise of each miner in a room, running a PSU for each, etc, etc.
