That's right. All power-hungry appliances (those that produce heat, mostly) get their own 240V circuit at amps typically ranging from 20-50. Electric dryers and water heaters usually get 30A @ 240V, stoves get 40A-50A @ 240V, and AC/heat pump units depend on size, but usually 30A+ @ 240V. It's really just our basic receptacles that are 15A or 20A @ 120V. This is plenty for 99.9% of uses, with the exception of some kitchen appliances that produce heat (e.g. a plug-in kettle.) If you bought a unit that required higher voltages and was rated for use in the US, you could always have an electrician wire a 240V circuit with one of the standard 240V receptacle types.
