That's certainly the case with me, Mike. I feel my electric bill is about $80 per month for the pump.

However, recently I've lowered the number of hours it runs and I'm hoping to cut that in half. Let's say that's so -- then $160 per season would be correct for a four month pool season (quite often the case without solar).

Before we bought the pool I understood the pump would be the biggest user of electricity next to air conditioning, and it's turned out to be the case. Then again, I have a 2 1/2hp pump (which apparently is overkill for our size pool).

Perhaps if you correctly size the pump AND run it the proper number of hours to clean the pool without over running it, then you can keep your costs down.
