We have an indoor pool. We used to run the pump about 8 hours a day, usually at night when electric rates are lower. However, we had some problems with our HVAC dehumidification system which requires that we run the pump 24/7 for constant circulation. I was concerned about our electric bills so we recently replaced the pump with a Jandy Pro Series Plus HP PHPF.50 at the suggestion of our pool mechanic. He said we would run 24/7 at about the same cost of the previous pump running 8 hours a day.
I wanted to replace with variable speed pump but our pool guy dissuaded me because we have a solar heating system on the roof and he said a variable speed pump would not be able to pump the water through the roof panels (ironically, my solar installer recommended the variable speed pump).
Anyway, our electric bill is still pretty high - maybe not as high as it would have been with the old pump but I'm wondering if a variable speed pump would still make sense. From what I have read they are much more economical. Anybody know anything about this??
