Built-in recirculation system

Navien ComfortFlow® is the first to incorporate a built-in insulated buffer tank and recirculation pump. The insulated buffer tank enables the NPE-A2 to operate at minimal flow rates.

The built-in recirculation pump allows the NPE-A2 to recirculate water either through an external recirc line or through existing supply lines while using NaviCirc®, without the need for external pumps or controls.
