My first post. We live in the southeastern US and put our pool in just under 2 years ago. I don't know very much about the ins/outs of the pool so please bear with me.

Our electric bill is averaged out so that we pay the same for 12 months and then it adjusts. We have seen great increases since adding the pool. My power company recently did a home audit to help us find ways to lower the bill. They found the pool pump using 1.5-1.6 KW per hour. I do have a timer. My pool is a 16X36 rectangular pool with a 8.5' deep end. So I assume it's around 26k gallons. I currently have a Pentair Easy Touch Control system with a one speed, one hp, Pentair Superflo pump. I'm trying to decide if a variable speed pump or 2 speed pump will help. My concerns are will operating on slower speed affect my salt water system? I have Pentair saltwater chlorine generator. Will it help lower costs? My pipes are 1.5" and I eve contacted Pentair. They said I need to determine TDH to determine correct pump. I haven't gotten good response or information from my pool company. I was thinking of a Pentair Superflo Variable Speed or perhaps an Ecopump. Just want to lower my monthly costs without sacrificing quality of the pool water.

Thanks for any help.
