13amp versus 32amp hot tub

January 11, 2022 / Sarah Elphick

There are a lot of choices to consider when purchasing a new Miami Spas hot tub for your home. Factors like size, shape, power, seat number, and the quantity of jets, will need to be decided, as well as choosing between a 13amp and a 32amp hot tub. If you are not sure what the difference is between the two, this article will help you to make an informed decision.

What’s the difference?

A 13amp hot tub benefits from simple installation; it is connected to the power source by a standard household 3-pin socket, which is why 13amp hot tubs are known as ‘Plug and Play’. This ease of installation is preferred by many first-time hot tub owners that want to be able to connect their hot tub and use it instantly. The price point of these units is also frequently more economical than 32amp features.

By contrast, a 32amp hot tub requires an electrician to connect the necessary wiring and components to the power supply before it is ready for use. 32amp hot tubs also consume more energy than others, but they have the advantage of more powerful jets and can run multiple pumps and the heater simultaneously. They may also benefit from a number of additional features that are not available in 13amp versions.

Is a 13amp hot tub cheaper than a 32amp?

There is a cost difference between 13amp and 32amp hot tubs. For tubs with comparative features and seating, a 32 amp version, such as the Emerald hot tub, will generally cost more to purchase depending on what you need; the extra investment may be worth it. 

Alternatively, those that want to use their hot tub for hydrotherapy purposes may prefer a 32amp hot tub with its additional power and better heating capabilities. The spa-like qualities of tubs such as the Tourmaline or the Ara appeal to many owners and can work especially well for those living in colder climates. 

Bigger amps mean that more than one pump can keep water cycling through the hot tub, and jets can benefit from stronger water propulsion providing better massage qualities. The added power may mean that running costs are slightly higher for 32amp hot tubs, but with the advantage of better heating and jet function. 

However, 13amp hot tubs can seat up to 5 or 6 people and are ideal for those that find the easy installation of plug and play an advantage. For soaking, relaxation, or entertainment purposes larger tubs like the Lynx or the Dorado are perfect. The single pump and heater configuration that is characteristic of 13amp tubs is enough to keep water warm and jets bubbling. There is also the added benefit of slightly lower running costs with lower amps, and the power it takes to run the hot tub and maintain water temperature will be less than with 32amp tubs. With available features like Bluetooth connectivity and LED lighting, 13amp hot tubs are a popular choice. 

Which tub is right for me?

Choosing between a 13amp and a 32amp hot tub will depend on what you want it for and may be impacted by where you live. If you happen to live in an extremely cold climate then you may benefit from a 32amp hot tub that can heat up faster and maintain water temperatures with ease. If you’re a keen athlete or sports player, you may wish to have the additional hydrotherapy power of a 32 amp tub. 

If you are using your tub for relaxation and want to simply switch on and get in, then 13amps will be suitable for your needs. Along with slightly lower costs in terms of initial purchase and running costs, these hot tubs have the added advantage of portability. Should you move house you can simply drain the hot tub, unplug, and move it to a new location.
