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.
With Navien's Ready-Link® cascading technology, when a unit gets up to 80% capacity the next unit will turn on to help meet requirements. The flow on demand ratio will continue until all 32 units are generating hot water as needed. The Navien cascading system also balances out the workload of each unit for longer life.
Building penetrations are reduced with Navien's common venting feature.
NaviLink makes it easy to communicate with your Navien systems anywhere internet service is accessible. The NaviLink module attaches easily to any new or existing* Navien tankless water heater, combi‐boiler and boiler.
* Existing installations may require the purchase of a new main PCB and front control panel.

The H2Air Kit utilizes the NPE-A2 pump to circulate the hot water for the hydronic air handler. This removes the need to purchase an additional circulator for the heating system.
Designed for retrofit and new construction, the Navien H2Air Kit™ includes an add-on controller to integrate space heating and DHW between any NPE-A2 series tankless water heater and a hydronic air handler.
