I'm new to the forum...and need some advice about changing out my pump. I have only one pump that I believe is about 23 years old. It is not too loud and seems to be working ok, but electricity in Palm Springs is very high and I seem to be constantly going into the highest price Tier in the summer which is $.32 kWh. I'm wondering if changing out my pump for a variable speed pump would be worth the expense. My current pump is a 2H and seems to use over 400kWh a month in the summer.
