Actually if you have a clothes dryer, range or water heater that is electric, those are always 220 volt.  Residential panels can have 220 volt if you want them to.  Yes, most residential electricians will look at you funny though.  I have an S9, D3 and a GPU miner on one 20A circuit that is drawing about 14 amps.  I use these (search on amazon):
Leviton 620PA 20 Amp, 250 Volt, Armored, Grounding Plug, Steel
Morris 82221 Industrial Grade Decorative Duplex Receptacle, 20 Amp Current, 250V, White
