Pool water

all pools have salt, including pools treated with "pucks". there is usually a slightly higher ppm in a salt cell pool compared to conventional pools but not enough to sway heater choice. I deal with raypaks and like the cupro nickel models but do nat gas heaters. if you dont plan on using the heatpump throughout the season install a bypass in the pvc piping. also make sure whomever installs it follows the particular instructions for that model, they all have a bypass of sorts in their required piping
