What is the purpose of spa heater elements?

What is the purpose of spa heater elements?

The spa heater element is a crucial part of hot tub heaters since it helps maintain consistent water temperatures for maximum comfort. When the water temperature drops below the set point, the spa’s thermostat signals the hot tub heater element to warm up the spa. Once the tub reaches the desired temperature, the element will automatically stop. 

The hot tub heating element is made of high-resistance materials that convert electrical energy to heat, enabling year-round use for continuous and uninterrupted enjoyment.

How do you know if a hot tub heating element is bad?

Various signs may indicate that a hot tub heating element is not working correctly. Address the issues below quickly by following electrical safety procedures or contacting a technician or hot tub manufacturer for assistance.


  • Inconsistent heating
  • Unusual noises
  • Visible damage
  • Rust or corrosion
  • Cloudy or discolored water
  • Malfunctions on the spa control panels


In addition to these signs, consider if the spa pumps are circulating water properly, as this can also impact the efficiency of the heating element for a hot tub.

How long should spa heating elements last?

The lifespan of spa heating elements varies depending on several factors. If the heating element is well-maintained and properly used, it can last 5 to 10 years or more. Investing in durable heating element materials, maintaining proper water chemistry and quality, and regularly cleaning the spa can help extend the lifespan of the heating elements.

Is it easy to change the heating element in a hot tub?

Changing a heating element for hot tub efficiency might seem more complex than replacing other spa components, such as hot tub pillows. However, with determination and some electrical knowledge, you can successfully replace a heating element by following manufacturer and safety guidelines.

Here are some general instructions:

  1. Ensure the power is turned off and the hot tub is drained.
  2. Carefully disconnect any electrical wires attached to the heating element and other hot tub components.
  3. Install the new heating element before reconnecting any wires, filling the hot tub, and restoring power.

Keep in mind that changing heating elements can vary based on the make and model of your spa.
