I get the sense some of these posts are talking about devices connected directly to the building's supply wiring (not to a receptacle downstream of the circuit breaker panel).
In the US all residential washing machines are 110V, as are gas dryers, but electric dryers take 220V.
In the US it's 30A minimum for an average "220v" (it's actually 240 V) outlet such as a dryer or AC, that's more than double what 13A 220V gives in the UK.
How many people in the US do really not have 220V in the garage? I bet a lot of homes have either a sub-panel (and thus could add 220V very easily) or a laundry (dryer socket, 220V).
No. Most US houses have, at most, a single 240V outlet in the laundry room for an electric dryer. Literally everything else is 120V. There is almost no household equipment other than drying machines that is sold taking a 240V plug.
Electric cars may change this. They haven't yet, at least not much.
That's not it. Electric dryers in the US are overwhelmingly 240V and on a 30A breaker. At 80% of rated, that's 5.7kW available. (Gas dryers here are typically on a 120V, 15A circuit.)
Every heat pump dryer I looked at on the home center's website is 240V. (Edit: I found one Miele on another home center that was a 15A@120V.)
In the US electric dryers run on 240v which has a different plug. Not sure how they are in the EU but it's something to consider when looking for one of those plug monitors
Driers, and similar high power appliances, don't use a single 120V phase. They use two phrases, 180 degrees apart in normal residential houses and 120 degrees apart in apartment buildings. Any American clothing dryer I've ever seen has 240V (slightly less in apartment buildings.)
A standard US dryer outlet is rated for 30 amps at 240v. For a sustained rating of 80% that's 5760 watts, which at 4 miles per kwh is 23 miles per hour, not 30.
Frankly it would take a hell of a lot to convince people to be ok with getting home, plugging their car in, and having the charge level go down instead of up. I certainly wouldn't be comfortable with it.
Funnily enough that's a normal practice in the UK/Ireland. In all the places I've lived, washer and dryer are plugged straight into a regular outlet (sometimes with an extension cord if it can't be reached).
Makes me wonder, why not make a 110v washing machine and save the trouble of having both 110v and 220v at home?
