I just installed a brand new Intelliflo (011018) pump.
When I measured the power consumption using current clamp, I measured about 120 watts when running at 1000 rpm and 100 watts when idle/stop. The power consumption during idle is what concerning. Do I have a defective pump controller? The 100 watt seems excessive for the electronics. Has anyone measured it for the same model (011018) or could provide the number for comparison?
I called up Pentair and the customer service had no idea how much the power consumption should be. She opened a case to talk to the engineer. For a moment, she was trying to convince me that 100 watt is nothing and that electric is charged by kwh so it's pennies every hour. But where the pump is installed, the electrical rate is $0.274 per kwh and the whole motivation to install variable speed pump is to save electrical cost.
The old pump is 3/4 HP and running for 5 hours per day equal to 2.8 kwh
The intelliflo running for 12 hour and 12 idle equal to 2.6 kwh
That is a saving of only 8% and it would hardly justify the cost of the pump.
