We are in the process of getting quotes from various vendors for an in-ground pool in our back yard. Due to the configuration of our lot, we'd like to place the pool pump and heater at the end of our side yard, which is about 60 feet away from where the spa will be located. The first two contractors didn't mention anything, but the third guy today strongly advised against putting the heater that far away and wants to locate it 20-25 feet closer to the pool in a less than ideal area. He stated that our bill will be "double" if we put it where we want it. While I'm sure he has a lot of experience, I am skeptical that an extra 40-50 feet of buried PVC (20-25' each way) will make that much of a difference in efficiency or heat loss. Any thoughts?
