You can run them in a shed no problem, the heat will warm up and dry up the place. Prepare a plan where you can heat up the place BEFORE starting up the miner, IE do not start the miner at -20 C
1 miner might not be enough to warm however. might need 4 hehe.
Okay thanks. I guess I could also just use a heater to heat up the place before starting them.
And the heat/cold mix won't create too much moisture?
As the miners heat the shed up, it will DROP the relative humidity in the shed, moisture won't be an issue.
Just make sure it doesn't leak, and that you have the ability to flow a little air through it even in the winter in case your miners are generating TOO MUCH heat.
