I've been working for some time on a pool that was designed from the beginning with low power consumption in mind. The pool is about 30,000 gallons and has 4 floor returns, a main drain, suction from the skimmers and return to the skimmers (for venturi). The Intellflo pump handles all the pumping needs eliminating the need for a boost pump for a pressure cleaner.
Today I powered it up and I thought there might be some interest in how much energy it is using running the basic functions.
gpm watts pressure
15 133 2.0
20 145 2.0
25 165 2.5
30 191 3.0
35 240 3.5
40 295 5.0
45 370 6.0
50 500 7.0
First off I wouldn't put too much faith in the back pressure numbers. The reading are such a small percentage of full scale that they could easily be off substantially particularly at the low end. Second the power numbers are from the unit itself not from a calibrated watt-meter. Still the data gives a good idea of how the system is performing which appears to be quite efficiently. Assuming 1 turn/day and $0.10/kwh this setup would consume less than $10/mo in electricity.
What these number don't include would be the cost of running any water fixtures, pressure cleaners or the venturi skimmers. I'll be testing the last of those next, then the pressure cleaner and will post the results as soon as I have them.
