Peter, dear - all American homes have 240V right to the electric panel. All of them, even in Alabama, Arkansas and West Virginia.
:-B
My range is 240V, as is the dryer. We use 120V at outlets because, as we were first (as is customary
LOL ) in providing electrical power systems (although 110V at the time) to a large number of people, we didn't have the technology at the time to use anything else and the voltage was really determined by inventions such as Edison's lightbulb. By the time electricity was widespread, it was too late to make changes as it would cost people billions (in appliances) to convert to 240V.
Yours was [widespread] later, made 240V from the start. We ought to upgrade our systems over the course of some years I should think.
As a side note, 120V actually has higher available amperage; amperage is what provides the heat, whereas voltage is the push, or pressure. 240V is safer due to the amperage being split between two legs rather than being on one so the shock danger is lessened.
