Water recirculatingpump

For outdoor tankless installation with a dedicated return line and with LESS than .4 GPM flow requirement. Up to 250 ft. of total pipe length.

These pumps are typically used in the Southern part of the US market where tankless heaters are installed outside to save on expensive air intake and exhaust systems. Use with tankless heaters without a built-in pump. Single pipe and dedicated return line models. Options include on-demand and timer controls.
