The Basic Components of a Hot Tub

As a popular option to relax at the end of the day, hot tubs are becoming increasingly popular in our region and Martella Electric Company has extensive experience in hot tub wiring and installation. That is why we provide useful information regarding the basic components of every hot tub. Hot tubs come in a wide range of sizes and configurations, but every system possesses the same basic components.

Key Elements of Hot Tub Functionality


  • Control system: This is the brain of the system and often takes the form of a digital keypad that can be located near the hot tub. The control is often integrated into portable units or located away from the tub for in-ground units. It’s an important part of spa wiring because it gives you the freedom to adjust the temperature, jet action, filtration, and more.
  • Filtration system: Clean water is critical for an enjoyable experience and the filtration system for hot tubs (that are not drained after every use) keep the water clean. Since filters and related equipment can often be located away from outdoor tubs, proper hot tub wiring plans should include the filtration system.
  • Pump and heater: Warming and circulating the water is at the heart of any spa, so the water pump and heater must be considered. Oftentimes, wiring a spa can be facilitated when these components are located adjacent to related equipment.
  • Lighting: A spa’s lighting system sets the atmosphere for the entire experience. Whether the tone is subtle or vibrant, any hot tub installation should address how lighting will be used in and around the tub.

Types of Hot Tubs

Portable Hot Tubs

Understandably, portable spas are designed to be moved. These manufactured self-contained units include all equipment required for operational use and frequently require only an electrical connection. While there are some units that can be plugged into an 110V GFCI outlet, 90% of hot tubs sold today require a 220 volt dedicated circuit

Planning should be performed before any hot tub installation in Delaware County to ensure that the spa wiring can be easily accessed for inspection and repair. Our expert electrical contractors are happy to help you with this step of your planning.

Built-in Hot Tubs

As the name suggests, built-ins are not intended to be moved and can be located both inside and outside. Spa tubs are commonly found in today’s modern baths and although they are self-contained, they require greater care during the installation process. 

Outdoor hot tubs have distributed systems which require much more planning. Wiring and installation can get complicated, so advanced planning regarding placement must be performed to simplify the process.

Our experienced Delaware County electricians can provide you with any electrical assistance that you need with your hot tub. You can reach us by calling (484) 341-7113.

What Are the Electrical Requirements for a Hot Tub?

Because water and electricity are within close proximity to each other in a spa environment, hot tub wiring in Delaware County  must be performed with utmost care and planning. At Martella Electric Company, we closely adhere to both national and local electrical codes to make sure that we meet all the necessary requirements to ensure that our customers can enjoy their spa safely.

While the Electrical Codes Can Vary Widely, Some Issues to Keep In Mind Include:


  • Electrical requirements may vary: While smaller portable hot tubs can simply be plugged into a 15-amp, 120-volt ground fault circuit interrupter (GFCI) outlet, larger units can require a much more complicated installation with a 50-amp, 240-volt feed. In addition, larger units require a more involved wiring plan.
  • Electrical disconnect switch: Hot tubs generally have power fed through a disconnect switch, which must be located at least five feet from the tub. Proper planning and placement of this switch can make wiring a hot tub much simpler.
  • Portable units should be UL listed: To confirm that your hot tub or spa has been tested to be safe and reliable, it should be labeled with the sticker from a recognized testing label, like Underwriters Laboratories (UL). Wiring a spa can be complex, but portable units themselves should be ensured with a safety label so that all hazards are minimized.

Hot tubs are an excellent amenity when they are installed and wired correctly and can be enjoyed for a number of years. Our customers are glad they chose us to help them pick out and install their new spas.
