Our "Hot Springs" spa has been one of best purchases that we made 25 years ago. We run ours on 110V, which means that either the jets run, or the heater with a circulation pump operating when the heater is running. If we would have set the same tub up for 220V, then both the heater, and jets could run simultaneously. We keep it at 105 degrees, so even with the cover off running the jets on a 20 degree day, it is still warm enough after an hour of operation (no reason to rewire the house for 220V). In 25 years, we have replaced the cover twice, and had to get a new pump once.

Ours is an all in one unit, with rigid insulation that doesn't fall out when moved, and could honestly be placed anywhere you have 110V, even a rooftop, or backyard.
