24 Hr Circulation pumps

24 Hr Circulation pumps
5.4 Total Score

Circulation pumps also called “Hush Pumps”, and “Silent Flow” pumps are sold as an advantage and often as an upgrade on Hot Tubs.

The Pitch is that they are small efficient pumps that clean your water 24 hrs. a day and are quiet and efficient to run.
It’s usually about a $500 upgrade and in my opinion, they are not as good a the alternative which is a high flow circ system.
  • Although they use a small amount of power they run 24hrs a day whereas the high flow pump only has to run about 4 hrs a day to clean the same amount of water both systems use similar amount a power per day.
  • They wear out more quickly because they run all the time.
  • The tiny energy savings against the increased cost of replacement parts make them more expensive over the long run.
  • They can only filter so much water a day. if you have a heavy bather load or a party or busy weekend of hot tubbing it can take them a while to recover whereas with a high flow system you can change how many hours the pump runs! So after a party, you can throw it on 24 hr mode (or any other amount) and it will filter up to 6 times more water than a circ pump can over the 24hr period.
  • Circ pumps are also low flow and this means you need to be very regimented with filter cleaning, if the filter gets too dirty they go into flow error easily, the hi flow systems don’t unless you are truly negligent.
  • The new anti vibration mounting systems make the good hi flow 2-speed pumps almost as quiet as the Hush pumps, there is very little difference.
I’m not a fan of these systems I think they are sold to add margin into a deal or added value perception. It’s all marketing spin.

Hi to start off thank for the info on the Master Spa, I have been I contact with my closest dealer that you recommend. After a bit of back and forth with the dealer I like the TS 8.2. How ever he said it is spec with a circ pump. Is this such a bad thing?


Hello , and thanks for all the info here. We Live in Prescott Arizona, and are considering a swim spa, a 14′ is an ideal size. However, there are not an abundance of selection at any local brick and mortar shops. I can afford a mid-priced unit, and would appreciate your comments and recommendations, along with a dealer name. Thank you in advance, Derrill

I am just getting started with trying to figure out what hot tub is best for me and stumbled onto your awesome site. I live in Boise, ID and only have space for a small tub for my wife and I. I had back surgery last Nov and am doing great, but my doc suggested a spa with powerful jets to keep my hamstrings/back/shoulder muscles loose and relaxed. Also, I’m 6’3, but I have a small patio space under a pergola where I have to fit a smaller tub. Have not wet tested anything yet, but am interested in the… Read more »

Hi Chris….I’ve decided your straight forward info is my best advice. Thank you for the time you put into this site. Recently purchased TS 8.25 @ home expo in Kalamazoo MI. Sales guy was pretty right on….was NOT planning on buying a tub that day! Seems to be a great store in Grand Rapids where this purchase was through. Something we’ve talked about for years. I’m confident, based on your videos/info, that we made the right decision. Except…the circ pump. Why add that to a tub that’s otherwise so well built if it isn’t the best thing? Can we just… Read more »

PS…. had the most difficult time deciding between that and the 8.2. Especially now I see that is your favorite and your personal hot tub. We are a family of six, went with the 8.25 for more legroom in the well, and the fact that second time buyers don’t usually go with the lounger. Wasn’t sure about floating up. I wish you were my neighbor or a personal friend! I so want to do everything right when we get it.

Same here….closing deal today. May I ask what sort of price? I’m at 8800


TS 8.25, w/cover, lift, steps, Orion lights. Delivery, etc. 9500 out the door.


Glad I stumbled upon your site! Living in Ontario Canada, electricity rates are important, so finding your energy efficient must haves was great. I have looked at beachcomber, and on your recommendation have sought out a master spa dealer. I have some emails and they claim msrp on the 8.25 is 21895…plus options. He then said they had 20 to 40% off instock and floor models. This puts it into the crazy beach comber range. I’m in Sarnia, so I could look in the port Huron Michigan area too. We have a family of 6. Personally, I just like floating… Read more »

I have the high-end Master Spa MP LSX800. I bought it last summer. I do believe it has a circulation pump that runs 24 hours, and which is also extremely sensitive; if the filters are noti cleaned at least once a week or more, it just stops running. It is the worse feature of an otherwise good product. Has Master Spa looked at correcting this? And do I really need the filter with the weird and expensive mineral insert? There are filters the same size with no inserts.

I live in Denver, CO and have been looking at Bullfrog and Wind River Spas, made in CO. What’s your opinion of those? I went to Colorado Custom Spas.

Thank you,


Hi Chris,

I am looking at the Vita Spa Jolie for the family. What do you think of that model. They want $7k.

Thank You.

One question I left out, please advise between use of Aquafinesse and Spa Frog Ease system. Appears more people have skin issues with bromine than with chlorine?

Hi Chris thanks so much for website and volume of info inside. After a couple months of research I narrowed my choices to the MasterSpa HL7 and the MaaxSpa 471. Your previous posts and website data clearly steer me to the Master HL7. I have concerns about the differences in power of the pumps, both have 2 pumps. Maax states it has 2- 56 Frame 2-Speed 3.0 HP 6.0 bHP pumps. What is the difference between HP and bHP ratings – are the Maax 3 or 6? Master rep states the company doesn’t talk about HP anymore, only amps. I… Read more »

We own a rental cottage that sleeps 12. We have a 6 person hot tub, that was bought for low price only. We are in the market to replace the hot tub, with one that might be able to handle the “bather load”. The hot tub is a big draw to our rental, and we want to make sure we get the right tub next – we considered a Hydropool self cleaning – but it sounds like that may not be the way to go (?) based on your review. Perhaps we should be looking at a commercial model (?)… Read more »


Hi Chris, love all the info you put out, thank you. Been doing a lot of reasearch on tubs, followed all your videos and have landed on the Master Twilight 6.2 over the Hot Spring Sovereign. Still had a couple questions though….. You’ve stated not to fall into the add on traps, one of them being a “hush pump”. However now they come standard on the Master tubs and I was wondering if they are still prone to the same problems like wearing out faster since they run 24/7 and not being sufficient for proper filtering? Also the vac-formed abs… Read more »

Chris HELP!!!! Here’s what I have: Brandnew in June Master Spa 8.25, Mast3rPur, EcoPur Charge and started the tub up with Aquafinesse (bromine) per your advice about micro-film. I’ve developed sever jock itch and I was told “you got it from your tub”. I’ve never had jock itch before and time line adds up. (What changed got a “hot tub”) Check levels every other day: actually a little obsessed about them, my water looks crystal clear all the time. Bromide levels approx. 3 to 4 Ph 7.2 (but I always have to add acid or Ph down) Alkalinity is at… Read more »

Dear Chris,
Just looking for a solid performing hot tub for medical and relaxation needs. Empty nesters so a 3-4 person spa would be great.
I am a 60+ year senior who knows nothing about hot tubs…..can you make a recommendation.

Thank you,
