How do you determine the proper size heater for swimming pool?
I was suppose to get the 350K BTU heater that's no longer available.
Pentair now offers 300K or 400K units.
The cost is only ~$65, but PB already delivered 300K unit.
I want to get some data on proper sizing of my 16'x40' FB pool, with all plumbing running with 2" PVC.
I have a hard time figuring out the proper size.
I know that any heater will eventually get my pool to temp, but what's the most economical?
Is the right direction to go with 300K unit and run the heater/pump longer, or do I blast the 400K unit and run it that much shorter?
Running gas is not a determining factor as we already have to redo the gas pressure to deliver either 300K or 400K to the pool.
