I have a 7 year old 40K gallon inground concrete pool and the 2HP pump needs to be replaced. We typically run it 8-10 hours a day and have a DE filter and a spa. I've had someone tell me that if I buy a smaller pump (1HP for example), I can leave it running 24 hours a day and still spend the same in electricity. The advantage being that the water is constantly being moved and filtered and stays cleaner, albeit at a slower rate. Just wanted to get thoughts on this from others here.
There's actually a pool pump forum? :-)
Thanks, I'll check the link!
No, this is the perfect place. In fact, I was over at "www.PoolMaintenanceAdvice.com" this morning posting my thoughts on Obama's new health care bill and someone replied to my post and needed to know where to get pool maintenance advice. It sent him to Freerepublic.
I, myself, like to pump and filter more and chemically treat less. But I am willing to pay a price for the electricity.
You need a big’un
Hey, it was worth the laugh I got reading your response!
I think yours is a good trade off, and it seems with the newer pumps I should be able to realize some savings even with the same 2HP size.
I have a 15k/gal pool and run the pump 4-6 hrs a day. I buy a bucket of 2” chlorine tabs and a couple of bags of baking and washing soda at the supermarket, a bottle od algecide and clarifier and it lasts all season. In Memphis.
“WHAT VOLTAGE 240?”
220... 221, whatever it takes. :)
Here you go. Now you have something exciting to do tonight.

Have you checked-out the Pentair IntelliFlo Pool Pumps?
They're expensive but can really cut your energy costs. Probably pay for itself within a year or so.

George: Well what's in this giant box out in the hall?
Kramer: Uh? Oh that must be it.
George: It's huge!
Kramer: Yeah, yeah, I got the biggest one they had. It's industrial strength. 16000 BTU's.
No such forum but rules require that we have a go at serious inquiries.
The site is real and appears to have what you need and more.
Check the label on your 2hp pump for the “SF” the true hp is the rated hp multiplied by the SF number ,, it can range from 0.9 to about 1.5 ... if your 2hp pump is a SF 0.9 then you really have a 1.8 hp pump and a 1.5 hp pump with a 1.2 SF will replace it ...
With a DE filter you have a problem with dirt and debris going back into the pool after every instance the pump shuts off and restarts .. I am assuming your DE filter redeposits the DE powder on the screens automatically at startup ... with every power cycle you let MOST of your dirt go back in the pool ...That is why commercial/public pools are required to filter 24*7*365 .... you should probably get a sand filter..
I hate it when people try to misle me!
8 - 10 hrs a day is too much....IF that's your average over a year.
My rule of thumb was to buy the biggest equipment you can afford...and keep you water chemically correct.
Good luck!
Yes, that said, does his service provider charge for tiers and time of day? If you exceed a certain level, they bump the cost per kwh meaning overall cost of ownership might be lower with a pump that draws less. Of course, if they charge more at peak then a stronger pump that can turn the water over faster but runs off peak would be the better choice.
IF YOU GET A SMALLER MOTOR AND RUN IT 2X AS LONG U WILL USE THE SAME AMNT OF CURRENT OVER A 24 HR PERIOD;;;SORRY 4 CAPS
