My pool pump is dying. It is a Pentair WFE-6, or model #011514, 1 1/2 HP single speed pump. I can replace it with an identical pump for around $550. Is it advisable to step up to a variable speed pump at this time?
My pool is an in ground pool, about 16,000 gallons.
We have a solar heater on the roof of the garage, the pump will have to push water up to and through that heater. The highest point of the heater is about 20' above the ground, it is about 130' run of pipe from the pump to the heater. 2" pipe all the way. We have a small waterfall, and in floor pop up cleaning heads.
What would be the proper variable speed pump to replace the 1 1/2 HP single speed pump?
Can a variable speed pump handle the extra load of the solar heater and still use less power?
Something to consider, we use the heater in spring, March, April, and May. Then again in the fall, October, and November. The rest of the year it is not used.
Thanks for your advice.
