Response to Hi Jennifer, Yes this heater comes with a 120V cord and plug which can be plugged into a standard outlet. This heater also has the ability to be hardwired at 240V. This heater would probably be overkill for a 70 gallon tub as it typically is used on aboveground pools ranging from 5,000 - 12,000 gallons. For something 70 gallons I would suggest one of our 120V electric spa heaters.
