I've seen/heard several dissenting opinions on pool heaters. Right now I have an ancient Purex Triton 350M (millivolt version) that I want to replace at the same time as the pump, and possibly at a SWG and an automation system. One pool company came out and recommended a Rheem 333k btu cupronickel heater, as they said they are dead reliable. However, I've barely been able to find any info on Rheem pool heaters other than that they are similar to Raypack heaters. I have not been able to find any pricing whatsoever on Rheem heaters.
A different pool guy came out to give a second opinion and he really seemed to dislike Rheem/Raypack and said they are unreliable and inefficient. He recommended a Hayward H-series or Pentair master temp. I've read very mixed reviews about the H-series and I don't want the Master Temp because it comes in either 300 or 400k BTU, and I want to stick with 333-350k BTU (to avoid having to pay to get the gas line changed). Both people seemed to like the Sta-rite Max-E therm, but it didn't seem to be the "heater of choice" for either.
With most brands it's easier to tell the difference in quality due to variations in price. It doesn't seem like pool equipment manufacturers work the same way, as everything is similarly price. My goal is to find the best quality and most reliable equipment.
I know my post is a bit long winded. In summation:
1. Does anyone know any further details about Rheem heaters, and anyone's personal experiences?
2. Hayward H-series vs Rheem vs Sta-rite
