A misconception that we hear all the time is that converting a spa to 220 volts will increase the jet power. Both 110v and 220v spas will keep the water hot around the clock. 220v spas can heat the water while the jets are on high or low. 110v spas can only heat the water while the jets are on low.
Correspondingly, how many volts is a hot tub?
If money is an issue and you need an inexpensive spa and don?t want to pay an electrician, you should choose the 110 volt spa.If, however, you want a spa that has enough power to run everything simultaneously while maintaining the desired temperature, with a lower montly electrical bill, the 220 volt hot tub is for you
What is the voltage on a hot tub?
Hot tubs with mixed voltage components (such as 120V ozonator and 240V heater) require 4-wire systems, which means they require an electrical circuit providing (2) hot wires, (1) neutral, and (1) ground wire. Check the owner's manual. The two hot legs (black + red) provide 240 volts (120V +120V).
How many watts does it take to run a hot tub?
At the time of publication, electricity costs more than 11 cents per kilowatt-hour. Using this figure, you can calculate how much it costs to use your hot tub. Divide your hot tub's wattage by 1,000 to convert it to kilowatts. For instance, a hot tub with a 240-volt heater uses about 7,500 W, or 7.5 kW.
