We have signed the contract and are waiting to start the pool build. The only thing I left out was the heater. We were unsure if we wanted it so we are having it prepped for one. Electric will be done and ready to add the heater if we decide on it. I'm still not sure if we will want it but I am thinking we will probably need a chiller. I was thinking of getting the Pentair UltraTemp 140 H/C. Any experience with this? We are in the Tampa area. The pool will be screened in so I'm sure that will block some sun.
