That is true, but previously you based your figures on horsepower, now
you're using the correct terms that I showed you.

You're charged in Kilowatt Hours used. It sometimes takes twice as long to
heat a spa at 110v as it would 220v because 220v is capable of doing
twice the work in half as much time. Not only can 220v use less wire size,
it can do so in a longer run.
