Two Question: 1. How does the hot tube get heated? 2. Does it just take a regular electric plug to the outdoor walk jack?

Hello Tony and thank you for your question. The heater inside the hot tub is electric and the hot tub has a GFCI cord on it that plugs into a standard 110 volt 15 amp outlet. The maximum temperature is 105 degrees Fahrenheit, which is the maximum setting for all hot tubs in the USA.
