SWG..before or after large heater

[tonyl]

Definitely after....the high concentration of chlorine gas will destroy the heater.

Just about every SWG manual that I have ever read suggests placing them AFTER the heater

Yeah, guys, I agree, after the heater makes the most sense.

I am pretty sure they adjust Cl output based on the temp of the water, tho.

I can't figure out how it compensates for "heater on" water of maybe 110 or so and "heater off" water of around 80 or less?

I believe the adjustment you're referring is for COLD water to prolong the life of the cell. COLD....is tough on the cell so the output is automatically adjusted with roughly 50 deg water or less. You won't notice a difference in 110 vs 80 degrees. My wife cranks our heater and I've never had any problems. Hope this helps, Tony

Hi, Tony,

Yeah, that explains that temp thing. Makes sense. Thank you.

my PoolPiliot has it's own temperature/flow sensor right by the chlorine generator.

Dave,

The Pool Pilot does have a temperature compensation that will increase the output if it senses an increase of water temperature. Note also that most heaters have a 2 - 10 degree temperature split between the inlet and outlet pipes of the heater. This should not fluctuate the Pool Pilot output that much.
