![]() ![]() In most cases, it requires its own dedicated wiring. Do not connect the hot tub electricals with other circuits.Since it is associated with water, even a 120v hot tub must be connected to a GFCI-protected circuit to minimize the risk of electrocution.This could be useful in situations where you need to shut down its electrical connection. Install an easily accessible emergency switch within five meters of the device.However, this is all just an estimate of the spa unit’s energy consumption, since a lot of factors might affect its power draw, such as: All you need to do is to enter the required info, such as how many watt the hot tub draws, your usage hours, and the electricity price. If you don’t want to perform this computation, an online calculator of an equipment’s electrical bill is an excellent alternative. In this scenario, if you use your hot tub for one hour a day and a total of 30 hours per month, you can expect your hot tub equipment to cost $28.8 in energy. If you want a further result, such as a monthly expected cost, multiply the calculated number by the total hours you use your hot tub in a month. As a result, the estimated energy cost is $0.96 per hour. If you live here in the United States, where the electricity rate per kWh is an average of $.16, you can multiply 6kWh by this number. So 6000 hot tub wattage divided by 1000 is 6 kWh, which is then multiplied by the cost of power, which varies depending on where you live. \textįor example, a hardwired 240v or 220v hot tub consumes 6000 watts when its heating and jet are activated. To calculate the energy cost of a hot tub, use the formula: Calculate the Electrical Cost of a Hot Tub However, when it comes to installation, this might cost a lot and requires a professional to do the work. It is also more efficient than a small spa in the long run. One big advantage of this unit is the ability to run water pumps at top speed while also using its heater function. Moreover, it draws about 6000 watts when the jet and heater are on. In most cases, it requires a 40-to-60 amp dedicated circuit with voltage requirements of 240v. The hardwired hot tub is the typical unit you see on the market. ![]() Furthermore, this is also great if you move houses frequently. It does not require electrical expertise to operate. However, when talking about portability, this unit is recommended. It can be plugged directly into a standard 15 – 20 amp outlet.Ī 20 amp hot tub is not as efficient as larger models. This type might draw an average of 1500 watts for the heater and 3000W if we count the pump as well. Types of Hot Tub 01 Plug and Play Hot TubsĪ plug-and-play hot tub is usually a 110v hot tub. Let us learn how much power needed for hot tub depending on its types below. In general, various types of hot tubs have different current ratings. ![]()
