"This miner won't work in a 110-120 VAC mains voltage system."
I'm looking for a decent miner to give me heat during the winter, but where i only have 120 outlets
It's pretty cheap to put in a singe 240V circuit near the panel. You can use some conduit to protect the cable and surface mount it all. That way you could run this miner.
Just a thought because using the miner as a heater isn't really about efficiency of the equipment. You need all the heat it can produce and you would be paying for it in some other way, so the coins are almost pure profit. You only need to earn enough to cover the cost of the equipment, and in your case the only limitation is running on 110. That being said you could look into older miners and figure out the best case for your situation.
