I did a cost comparison between running my pump during on peak & off peak hours. The results are quite amazing. In my case I will save approx $42.00 a month running the pump off peak during the summer and $10.00 a month running the pump off peak during the winter. This averages to approx $26.00 per month or a savings of $312.00 per year. So my question is how many of you run your pumps, on peak or off peak?
