The most advanced condensing tankless water heaters in the industry with exclusive ComfortFlow® technology for continuous hot water.
Navien ComfortFlow® is the first and only system that incorporates a built-in insulated buffer tank and recirculation pump. The buffer tank eliminates the “cold water sandwich” effect and issues of minimum flow rates commonly found in other tankless water heaters. The recirculation pump saves on water bills by reducing the time to get hot water. When activated, the optional ComfortFlow mode results in additional energy usage.
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 16 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.

H2Air Kit optional combination space heating and domestic hot water system
The H2Air Kit utilizes the NPE-A 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-A series tankless water heater and a hydronic air handler.
