If you are going to heat the entire pool then a 400,000 BTU heater is best. Not sure if you wish to have a Heat Pump or a true Heater. Since you have all Pentair equipment then you can stay with that mfg. Raypak also makes a heater or Heat Pump depending on what your preference would be. A heat pump is normally all electric whereas a heater can be run by natural gas or propane.
