Circulation Pump - are they truly a cost saver?
soon2float:
We are looking for a tub about 8' square with 1 lounge, in the 5-6500 range.
Several we have looked at have the circ pump as an option or not at all. Does anyone know if it truly is a savings.
We have looked at Artesian, LA Spa Heet, and Coast. Any other recommendation are very welcomed.
Thank you so much,
Lisa

Both methods are fine for filtering but when comparing the two I like the circ pump idea for other reasons. It is a bit of a cost saver (not major) but more importanatly to me, it allows for 24 hr ozone and is much quieter.

Spa Tech,
Thanks for answering. Why is 24hr ozone any more effective than the regular pump occassionally running keeping up temp running through the ozone filter?

Circ pumps run 24/7 and therefore you're getting ozone mixed with the water 24/7. With a 2 speed pump you're getting ozone during the filter/heat cycles (plus any time you're in it with the pumps on) which typically equates to about 6-8 hrs per day. Therefore, you're getting ozone input into a spa with a 24 hr circ pump about 3-4 times more often than a spa without a circ pump. I'm not saying this should disallow any thoughts of getting a spa without a circ pump but it is a big positive on the circ pump side.

When I was shopping, the Marquis dealer made a very effective arguement for using the main pump in lieu of a small 24-hour circ pump. Marquis apparently did offer the 24-hour pumps for a few years and then changed to their current design. The main reason was that the 24-hour pumps only last for a few years before they fail.
On the plus side, the 24-hour pumps offer constant ozone, even heat distribution, and clean water at all times.
In the end I concluded that how the pumps are configured ranks along side of horsepower ratings and the number of jets. In the final analysis all not very important relative to the more important issues of reliability, ergonomics, ease of use, and so on.
Regards,
Bill
