I have the Pentair Easy Touch panel, a pentair pump, and am leaning towards a Pentair heater. Pool size is 16x36, ball parking a little under 20k gallons. Pentair MasterTemp is what I am looking at, the 300k BTU natural gas version. Any other heaters that play nice with the Easy Touch that I should consider? Or is this a "6 of one, half a dozen of the other" type choice, and sticking with all Pentair is just simpler? Thanks
