110V Vs 220V Hot Tub

For those who aren’t familiar with the hot tub industry, it may come as a surprise that there are hot tubs that run on different voltages. What’s the difference between 110V vs 220V hot tubs? In this article, we’ll describe these differences and go over some of the advantages and disadvantages of each type.

Plug And Play Versus Hardwired Hot Tubs

The terms “plug and play” and “hardwired” are just simpler names for 110 volt and 220 volt hot tubs. Plug and play hot tubs run on 110 volts whereas hardwired hot tubs require 220 volts. Plug and play hot tubs have that name because they can be plugged into a regular household electrical outlet. Hardwired hot tubs, on the other hand, require a larger electrical receptacle that may only be found in areas where an electric stove or washing machine would be plugged in. If you’re planning on purchasing a 220 volt, hardwired hot tub you’ll need to hire an electrician to install the appropriate electrical outlet.

Ease Of Installation

Because you can simply plug a 110 volt hot tub into virtually any electrical outlet in and around your house, there’s no need to hire a professional to power your hot tub. Once the hot tub is in place it simply needs to be plugged in to power the various mechanical components.

220 volt hot tubs require the professional installation of a GFCI (ground fault circuit interrupter) to protect users against the higher voltage. This isn’t a DIY job. It needs to be done by a certified electrician and will require a connection with the household circuit breaker box. When it comes to ease of installation, the 110 volt model wins out.

Installation And Operational Costs

When considering like for like, the upfront costs of a 110 volt hot tub will generally be cheaper than a 220 volt model. This is because there’s no need to hire an electrician for installation, but also because many of the components of a 110 volt hot tub will be less powerful and therefore cheaper.

When it comes to operating 110 volt and 220 volt hot tubs, the 220 volt models will be cheaper to operate over the long run. Because 220 volt hot tubs can accommodate a more powerful water heater they won’t need to run as long to maintain the water temperature. 110 volt hot tub heaters will ultimately consume more energy, especially in colder weather.

Water Heating Abilities

Because 220 volt hot tubs have more powerful water heaters it takes far less time to bring cold water up to optimal hot tub temperatures. In a 220 volt hot tub, you can generally bring tap water up to the hot tub’s maximum temperature in about six to eight hours. In a 110 volt hot tub, this can take as long as 24 hours.

Water Heater Versus Water Pump

The amount of power that each type of hot tub can draw will also affect the capabilities of the water heater and pumping system. 220 volt hot tubs can power multiple water pumps, whereas 110 volt hot tubs are somewhat restricted in this area. In a 110 volt hot tub, you cannot run your water heater when the water pump is operating at top speed. 220 volt hot tubs allow both of these components to run at maximum power simultaneously. This can be a problem when operating a 110 volt hot tub in the winter. You’ll have to choose between maintaining the water temperature or receiving the most powerful massage.

Portability

If the portability of your hot tub is an issue, you’d be better served by choosing a 110 volt model. It’s not that a 220 volt hot tub can never be moved, but it would require more planning and the help of a certified electrician. If you want to retain possession of your hot tub, but can’t commit to a long term home for it, a 110 volt hot tub will likely be the better choice.
