It doesn’t happen often at Hydropool, but once in a while we do get customers who want to know the various parts of a hot tub.

We are commonly asked about the various parts of a hot tub. What are the parts of a hot tub?

  • IT MUST BE HOT: There is a heater
  • POWER: There is a motor, which is also often called a pump (often more than one of these, depending on the model) that powers the water through the jets
  • CIRCULATION: Pipes and jets
  • A TUB: An acrylic shell and synthetic cabinet
  • CONTROLS: There are controls, lights and an electric system
  • FILTRATION SYSTEM: Filtering and sanitizing your water

All of these components must work together for your hot tub to work. But there’s one little part left off here, and that’s the blower. It’s not on every hot tub, but we are asked about from time to time so we wanted to write this article to explain exactly what it is.

A hot tub blower is the component that creates air bubbles in the water. For this reason, it’s also known as an air pump or a bubbler. 

But there’s more. In this article we will explain:

  • How a bubbler or blower works
  • What the advantages of a hot tub blower are
  • The different power ratings of hot tub blowers

And we will tell you where to go if you need even more information about hot tub blowers!

 

 

How Does a Hot Tub Blower Work?

A hot tub blower is composed of an air pump that’s attached to a fan, all powered by the hot tub motor. The motor forces air through a length of piping and into the hot tub resulting in bubbles being blown into the water.

Some people confuse the hot tub blower with the water jets that create the intense massaging effect that hot tubs are known for. That water is powered by a hot tub’s pumps.

What does a blower do for you, the hot tub owner? A hot tub blower is a device that powers air into your hot tub, intensifying the pressure in the jets and creating a stronger jet stream as a result.

What Does a Hot Tub Blower Do?

  • The bubbles created by hot tub blowers can produce a refreshing, yet relaxing atmosphere.
  • The combination of air and water creates a flow of bubbles that adds to the effects of the massaging jets, often by creating a pleasing sensation on the skin.
  • Some people also like the fact that the bubbles create a cover for the bathing bodies below the water line and remove any awkwardness that may be caused by exposure.

What Kinds of Hot Tub Blowers Are There?

This generally only matters if yours stops working. Here’s what you need to know in that situation.

Although they all do the same thing, there are a number of different types of hot tub blowers on the market. Understanding these differences is important if you’re looking to install or replace one. Blowers are available to run at 110 or 220 volts and there are many different types of electrical plugs to choose from.

Hot tub blowers typically come in 1, 1.5 and 2 horsepower ratings. Which one is best for your situation will depend on how deep the water is in your hot tub, the amount of use it gets, the diameter and length of the air piping and the number of sharp angles the air has to navigate on its way to the water (of course, there’s always that tradeoff: the more power you have in the blower, the more it will cost you to use that power).

When in doubt, or to see what kind of blower you have, look at your owner’s manual or contact your local retailer.
