What is a Circ Pump or Circulation Pump? Do I need a Circ Pump? Why? What makes a Circ Pump essential for a quality hot tub?
In the blog below, we hope we can answer all of your questions about Circ Pumps.
What is a Circ Pump?
A Circ Pump is a low-flow pump that comes standard on most hot tubs carried by The Spa and Sauna Co. A Circ Pump keeps the water in a hot tub circulating at all times. This is done so the water inside the hot tub is being filtered, heated, and treated with sanitizer 24/7.
Do I need a Circ Pump? Why?
A Circ Pump is used to enhance your hot tub experience.
Since hot tub water is only changed about every 4 months, Circ Pumps are used to keep water fresher and cleaner for a long period of time.
The Circ Pump ensures that your water is moving and clean.
While you can still purchase a hot tub without a Circ Pump, our hot tub experts at The Spa and Sauna Company recommend that you purchase a hot tub with some sort of filtration system.
Hot Tubs without a Circ Pump often use a two-speed pump. The pump is on low-speed when circulating the water and on high-speed when running the jets.
Just like switching a light on and off often burns out an incandescent light bulb faster than leaving it on all day does, constantly changing the pump speed of a two-speed pump wears out the motor in the hot tub faster than using constant filtration provided by a Circ Pump.
If replacement and maintenance costs are a concern to you, you may be better off making a slightly larger up-front investment, in exchange for less repairs and replacement costs down the line, as well as a superior hot tub experience.
What makes a Circ Pump essential for a quality hot tub?
Would you like your water to be refreshed, filtered and heated, while you are in your hot tub? Without a Circ Pump, you need to alternate between those functions.
It comes down to what is more important to you. A hot tub with a Circ Pump has an easier time maintaining the temperature you’ve selected. That’s because while you are in the hot tub, the water circulates past the heater, and fresh, sanitized, heated water comes out of the jets, while you use your tub.
With a two-pump system, you have to decide between heated water or moving jets.
Most people have a more enjoyable spa experience, when they can have both at the same time.
Here, at The Spa and Sauna Company, it is our goal to provide you with the most enjoyable hot tub experience, at a budget that suits your needs.

Thank you, excellent presentation. I work on boats and just last week tore the large pump and motor out of my Gulf spa and replaced it with a Jabsco 12 volt marine pumps...upgraded the thermostat and love the silence and efficiency of our new and improved spa. Great video.

The larger dual speed systems move the water every thirty minutes throughout the plumbing. On a single pump spa the entire plumbing has moving water and zero stagnation. Some larger two pump spas will have roughly 50% of the plumbing not having consistent water movement. The smaller circulation pump only runs water through a tiny 1/2 - 3/4" line from the circ pump, heater and filter. So in essence 99% of the tubs plumbing will be stagnant 100% of the time while filtering/heater. Is that a correct statement?

Thank you for your comment. Many spas with a circulation pump also draw small amounts of water through the jet pump(s) plumbing to make sure the water is turned over when the jets are not in use. Many spas with a circulation pump also have the ability to cycle the jet pumps on daily automatic cycle.

That`s very interesting subject. However, does it mean for outdoor spa systems, please? What about indoor spas? Does it make sense to install a circulation pump? Thank yoiu

Hi Alexander, it depends on your brand of spa. All of the spas we specialize in are outdoor spas, but can be placed indoors in some situations. We don't generally recommend installing a circulation pump on your spa if it doesn't already have one because of the cost. It's usually more cost effective to upgrade your spa through our Hot Tub Trade In program than to install a circulation pump. Your best bet is to contact your manufacturer and discuss your options.

@@TheSpaSaunaCompany O can find the main reason to install a circ pump is to keep water heating all the time you want (not only during whirpool jets are working). I have realized that if we have one pump only, all the heating functions switched off when you are soaking. No water flow via heating element- no heating. That`s not nice. I`d like a circ pump to support a low water flow for keeping desired temperature. Unfortunately our SPA manufacturer has disappeared :) It was Lanark

What are some of the names and models of dedicated circulating pump options that I can install?

[@TheSpaSaunaCompany]

Hi Stuart, we generally don't recommend installing a circulating pump on a hot tub that doesn't already have one simply because of cost. It will usually make more sense cost wise to upgrade your tub to one that comes with a circulating pump. That said, it all depends on what make and model spa you have. For example, on Hot Spring Spas tubs like we carry, the circ pump is referred to as the Silent Flow 5000 because it moves 5000 gallons of water a day silently. Other manufacturers might not have names for their pumps, but they'll be able to clarify if you can install one on your spa. Hope this helps!
