Navien condensing tankless water heaters boilers for residential and light commercial applications use innovative high-efficiency technology to provide a comfortable environment. Navien NPE-180A High-Efficiency Condensing Tankless Water Heater is the only tankless water heaters with ComfortFlow to save you time and money while you enjoy endless hot water.

ComfortFlow® Recirculates Hot Water Through Supply Lines, Eliminating Wait Time for Hot Water.

Exclusive built-in recirculation system included on all Navien NPE-180A models.

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.

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.

At the push of a button, the Navien HotButton hot water system activates the internal recirculation pump and gas-fired burner to heat water in the supply lines to provide hot water whenever it’s needed.

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 circulatory 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.

Unlike the conventional storage tank water heaters that will eventually run out of hot water, Navien’s Condensing Tankless Water Heaters can deliver an endless supply because they only produce hot water when you need it, which limits energy and water waste. With a Navien Tankless Water Heater, you will never have to worry about running out of hot water, no matter how much you use at a single time.
