SWG..before or after large heater

[rmeden]

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.

Hi, Sean,

Thanks. The reason for my post is this is a REALLY big heat exchanger and, while it is not yet running, I am calculating 20+ farenheit temp changes. Still no issues?

I have an autopilot system. Would it be feasible to move the sensor section between the filter and heater. Replace the sensor section with a piece of pipe and leave the cell after the heater. Just a thought.
You would have to be carefull not to turn off or reduce the flow thru the cell. Since the flow sensor would not be at the cell.

20 degree split on any heater, regardless of heat exchanger size, means insufficient flow through the heater. This can lead to premature damage. Other areas of concern if this is a heat pump is the evaporator coil. Any blockage around the coil will cause inefficiencies and higher temp splits.

splitting the tri-sensor from the manifold....hmmm too risky. All you need is for the cell to be scaled and the tri-sensor to not detect this condition (blockage of flow) and you can have a read disaster. "Don't do it" is my 2 cents, besides, it voids warranty.
