All About Hot Tub Pumps | Do You Need a Hot Tub With a Circ Pump?

[@captainron8111]

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?

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!
