Today’s Patio and Spa at Cactus and Tatum (they’re awesome) had this Pentair IntelliFlow Variable Speed 3HP on display with a computer program to estimate your electricity bill saving’s per month. The knowledgeable and helpful salesman showed me something like this on the fancy computer screen:
Hours per day: 10
kWh charge: $0.13
Old 2HP pump cost per month: $97.50
New pump cost per month: $12.48
(NOTE: The picture above depicts $55/mo savings b/c I went back and put in my actual kWh rate, $0.09 and snapped this photo after I wrote this article.)
The screen was animated to look pretty, but the calculation was pretty simple. The way this pump saves so much is it only runs at high speed cleaning mode for 2 hours a day at about 1 kWh and then very low speed for 10 hours a day at about 150 Wh (that’s 0.15 kWh). My old pump only had one high speed and consumed about 2500 Wh for the full 10 hours a day it ran.
My old motor burned out and I needed to buy a new one. My decision to buy this Pentair IntelliFlow Variable Speed unit for $1250 (grand total out the door, with pro certified install and sales tax) over the $450 (grand total out the door, w/ sales tax, but self install) was based on long term cost savings. At $85/mo in electric bill savings, I’ll break even on the cost difference in 10 months, and the unit will pay for itself after 15 months. After that, it’ll be $85/mo in my pocket. Sounds like a wise investment…..
BUT, will it really save me $85/mo? REALLY REALLY?
