Intex pump upgrade

Postby iowapool1492 » Wed 16 May, 2018 14:58

Hi all,

I need to crank up the GPH on my Intex Krystal Clear 1500 GPH Sand Filter Pump & Saltwater System with E.C.O. , the reason being the heater I bought for it

(link here sorry couldn't URL)
https://www.amazon.com/gp/product/B071C ... 3613854011

requires a higher GPH. Short of buying a completely new system, would anyone know of how I could upgrade to a higher GPH?

I've searched what I think to be the entire internet for a different pump for the system, but haven't had any luck. Could it be as simple as splicing in any 2500 GPH pump, or would the mismatched GPH be a problem?


Thank you very much!

Why do you need to increase your GPH? 1500 GPH should be suitable for that heater unless you have found a specification that states otherwise?

However up grading to a sand filter will vastly improve things over the pathetic little cartridge filter. Intex do a small sand filter about 12" dia but personally I would try to find a 16-18" sand filter.

I checked that link
I don't see why you would need to pass in excess of 1500GPH through this little 2kw heater (electric showers are bigger)
What is the pipe size, it doesn't look big and I doubt that you could pass 1500GPH through it

Thank you very much for the responses, & sorry I should have put more specifics in my original message. I talked to the guy that makes them - 1500 gph is the minimum flow rate for the safety valve to stay open - (it currently closes with the current 1500 gph). FYI I also have a solar heater w/ 40 ft. of tubing running back and forth to it; he feels that the additional work the pump has to do to get water back and forth to the solar heater lowers the gph enough to cause the safety valve to close.

FYI my small pool is in the shade most of the day so that's what's going on w/ all the heaters.......

Thanks again!

Tell the guy who makes them to make them better! they should be ok at 1000 GPM.
To answer your question better you really need to know the flow rate you are actually getting but in any case that puny little filter is not big enough to handle a large pump so I still suggets the change to a larger sand filter setup

My 5kw heat pump requires just under 2000 UK gallons per hour for up to 27kw output
Don't go for that expensive way of doing it get a heat pump

Thanks for the response - I actually do have a sand filter and salt water system...just the flow rate isn't high enough for the heater.

thanks, but our pool is only a small 8' x 11' oval/2000 gallons - a great idea though for a bigger pool though

Look at the maths
It takes one BTU of energy to raise one pound of water, one degree F. Water is 8.3 lb/US gal so 2000 gallons = 16600 lbs. requiring 16600 BTU's of energy.
1 kw/hr = 3412 BTUs so (3412*2) = 6824
16600/6824 = 2.43 hrs to raise the water 1 degree F
This assumes 100% of your energy goes to heating the water and none of it is lost.

A Heat Pump is a more efficient way of heating your pool electricaly
Regardless of this get a thermal cover
