Do hot tubs require 220/240V electricty? The answer is… it depends. Not all hot tubs are wired the same or equipped with the same components. Some hot tubs can be plugged into a 110/120V outlet, and some need to be hardwired at 220/240V.
Some hot tub models are factory configured to operate with a 110/120V plug-in GFCI power cord. These models are called “plug and play.” There are also some hot tubs which will allow you to “convert” the voltage from 110/120V to 220/240V, which in turn allows for a higher heat output from the electric heater. And then some hot tubs come only as a 220/240V unit.
“Voltage is the electrical unit of measure of electromotive force. Electromotive force is provided by a source of electrical power, usually household power lines wired to a main service panel.” -PHTA Service Tech Manual
So, what voltage do you need?
Use the following list to help you decide which voltage is best for you: *
- Just plug it in
- Heats slowly
- Weaker jet pressure
- Smaller hot tubs
- Probably needs an electrician
- Heats more quickly
- Stronger jet pressure
- Larger hot tubs
