After months of frustration with my new energy efficient water pump, this week I finally found out that there may be exceptions to the claims that energy efficient pumps save on your power bill. Long story short, even the Pentair tech support admitted that he had learned something from my experience.
Problem is that I have not seen any reduction in my power bill when I installed the Pentair energy efficient pump last November. After going round and round off and on for months, I found out by hook and by crook that since I have solar electric power production (NOT solar water heater) that my bill is already at tier 1 AND I have a salt water pool, an efficient pump will not reduce your power according to my experience.
I know, I know that I will probably be the first and only customer that reports this! The only other remote problem, which the company denies completely without checking it out, is that I just might have a defective motor. I have not run any tests because I am just an ordinary customer and the local installer is useless and tried to blame the entire matter on me personally and with the monitoring system! Its a Jandy. I was not happy with that remark and reported him to the Pentair!
Futhermore, Edison, my power company to which I got a check because they want people to purchase this pumps addmitted that they never had any independent studies that verify the claims of saving "Up to 90% of your water pump power useage" (From the Pentair website). Furthermore, the edison rep said that YOU HAVE A PROBLEM WITH THE PENTAIR NOT US! I was stunned by that remark. I was not accusing them of anything, I was just informing them that they ought to study the claims made by the industry.
Good news is that Pentair rep FINALLY understood that I may have a point because of the solar energy production that already puts me in the lowest cost. But he wants me to talk to THE expert of the company.
Thats my story. Bottom line is that if you have a salt water pool (requires a flow rate of about 1000-1500 rpm from the pump) and you have solar power on your house (not solar water heater) and your current pump is fine, you may or maynot get the reduction in your power bill if you decide to purchase the variable energy efficient pump.
I did not after 8 months of experimenting.
Have a good day,
