The US is one of a few countries that houses are for the most part just 110, and even then most houses have 220 installed (think your dryer), you can get more 220 breakers into your house by getting an electrician and having some rewiring done.
Yes, the US is one of the few 110 places. I just happen to live here so...
220 in many locations is not as common as some people think. The condo I live in now is 110 only. Even in the entire community, Condos, town homes & full detached houses the master plan is all 110. It's happening more and more if you have gas for the dryer / oven / stove / etc. 220 was not needed. Actually a bit of an issue now with a lot of people getting electric cars and then dealing with pulling in 220 from the street.
If a DC in the US isn't using 220 they are fairly dumb, power efficiency is usually better at the higher voltage and most electronics are ok up to 240.
Billing reasons. Racks come with 20A of power. Then in the small print 110V.
Yeah, it's scummy but what can you do.....
This would be nice, I never had one but heard when they worked they were great. Unfortunately it doesn't make sense for manufacturers to cater to the home miner anymore; if they did a run of something like this I imagine the price would be ridiculously expensive in Cost/TH.
True, but a know a lot of people who used them for space heaters during the winter.
You can either turn power to heat with 0 Th with your space heater ot turn power into heat with 8.6Th with your R4
Cost to run is about the same :-)
