The necessary electrical outlets for a washing machine are standard 110V outlets, every apartment in New York has them. They might not have convenient water hookups for them,though.

Clothes dryers usually usually take 220V outlets, which an apartment might not have.

Heat pump dryers, now common in Europe, use about 800W which is within the 1500W maximum for a normal American outlet. Maybe these will become more popular in New York apartments?

They are more expensive to purchase, and take longer to dry the clothes, but use much less electricity.

Yet another example of shitty infrastructure, having to juggle different voltages and power outlets.

In fairness, my modern Danish apartment has a different voltage and power outlet in the place for the tumble dryer: 400V and probably one of these [1] though I've never pulled the machines out to look.

In practise, the massively power-hungry dryers of decades ago aren't very common, so my dryer is connected to a normal 220V outlet.

(Three-phase power in an apartment is now only used for the oven and hob, but is used in the building for the lift and the EV charging points in the basement.)
