If the water is cooler it will have a higher rejection rate as it makes the pores on the RO membrane close up tighter.
I have a 100ft coil of tubing inside my sump before the RO unit to help bring the input temp up from the underground temps and it also helps cool the tank water.
Interesting....guess I should go to more meetings. Since mine's hooked up to my sink, I wonder if the cost of heating the water to decrease the rejection rate is worth wasting less water? I'm guessing not. Kevin has a nice way of making it work though!
