My electric bills have increased from $150 per month for the first three years after my pool was built to $400 - $500 per month the last two summers. I replaced my two-speed pump three years ago as my original 1 hp two-speed pump kept failing.
Being a bargin hunter, I purchased a 1 1/2 hp two-speed pump from an on-line vendor (have read lots of negative feedback on this vendor since my purchase), and I have worried that the pump is not quite right and I now believe I purchased more hp than I need. I installed the pump myself, so who knows maybe I did something wrong with the wiring. I am willing to do whatever is necessary to lower my electric bills by at least $200 per month.
There are only two things that run in the summer that do not run other months; pool pump and central A/C for house.
I have been trying to pinpoint the problem. My pool builder was over yesterday and today, and he said I could take the motor off and take it in to an electrical motor shop and have them check to see if it is out of balance. He also said if the motor was made in China, that is was a piece of junk. He said that is why he switched from selling this manufacturer's products because they are now making their equipment in China. Need to take a picture of the motor and equipment, which may help suggestions.
He agreed something is wrong given the amount of my electrical costs. I asked about replacing the entire pump with a different brand, and should I consider replacing all my PVC at this time given the age of the pool. One thing I appreciate about him is that his always looks for the least expensive solution. However, I wouldn't not have minded if he provided pros and cons.
I also obtained my neighbor's electrical bills just to see how I compared. As you can see in the attachment, it is in the summer when my costs are more than double the neighbor's. I am also attaching my electrical usage and costs if that gives any insight.
Appreciate all suggestions
