Trying to find some BTC miners that are reasonably low power.
Ideal range would be 300-600 watts. Something efficient and quiet. I need the lower wattage as we we limited in the US. Looking for something I cohk

I use Asics to heat my home in the winter, but I need a couple more to really provide complete coverage.

Trying to find something that is efficient, quiet, and not break the bank. Does anybody have any suggestions? Also, must run on 110V.
