We have a 30,000 gallon pool that we heated with a Paypak RP2100 for 11 years before it needed replacing. We live in central Maryland and it sits out in the elements year round and we have been very pleased with it.
I have a 40,000 btu forced air propane heater and its orfice is .085. I ended up drilling it out to 1/16", removing the regulator and hooking it up to NATURAL gas and it works fine. [for added info not pertaining to original question]
