I have single speed 2HP pump motor on my 11k gallon pool and spa. I'm new to pools and we bought this house with the pool last September. My current pump works fine (although it's very loud) but I've been running it less than 2hrs a day during winter and the water has been clear.
Now that the summer is coming, I'm worried that I'll need to run it much longer (6hrs). With $.30/kwh energy costs, I'm considering replacing my pump with a Intelliflo VS. The pool store is offering a free install for ~$1000 after rebate.
So my question is: is my 2HP pump too big? Is replacing it with a VS pump worth it on a small pool?
