Navien NPE-A2
The new Navien NPE-A2 series are the most innovative condensing tankless water heaters on the market today. These tankless water heaters deliver a continuous flow of hot water for as long as you need it. There’s no waiting for a storage tank to warm up. A few of the new features are listed below.
A – 2″ PVC up to 75 feet and 1/2″ gas up to 24 feet
B – High efficiency up to 0.95 UEF and up to 15:1 TDR
C – Durable dual stainless steel heat exchangers
D – EZNav multi-line control with built-in intuitive software
The new NPE-A2 has a built in re-circulation system! The system also has a insulated buffer tank along with the re-circulation pump. This makes the new Navien tankless able to operate at much lower flow rates than in the past.
The built-in re-circulation pump allows the NPE-A2 to recirculate water either through an external re-circ line or through existing supply lines while using Navi-Circ without the need for external pumps or controls.
Multi-line control with built-in intuitive software!
Navien’s new backlit EZNav control panel uses simple text and icons to make set up, operation status, and troubleshooting faster and easier than ever before. Your Navien control center is now more intuitive than it has even been before.

Re-circulation valve for use with Navien NPE-A2 Tankless Water Heaters.
This unique vale is designed for re-circulation of domestic hot water in applications where a dedicated return line is not available. Navien calls this system their “NaviCirc”.It is a simple plumbing device that uses the existing hot and cold water lines to reduce the wait time for hot water at the faucet without the need for a dedicated re-circulation return line.
- Designed and optimized for use with NPE-A and Navien NPE-A2 Series tankless water heaters.
- Automatically blocks circulation when the hot water temperature within the valve is about 95°F (35°C)
- Compatible with the Navien HotButton Kit for demand-type re-circulation systems
The NaviCirc re-circulation valve works best if installed under the furthest accessible fixture away from the water heater. With the NPE-A or NPE-A2 unit’s built-in pump, water circulates through the NaviCirc to preheat the hot water lines, using the cold supply line as the return line back to the water heater.
Navien NPE-A2 Models
The NaviLink module makes it easy to communicate with your Navien systems anywhere internet service is accessible. It easily connects to any new or existing* Navien NPE series tankless water heater, NCB-E series combi-boiler, NHB series and NFB series boiler. Once installed, simply download the free app on your smartphone or tablet. Then you will be able to turn your unit on or off, change the water temperature, monitor system status and even activate the re-circulation system on your NPE-A or NPE-A2 tankless water heater with an installed HotButton Kit.
So you can relax… with internet connectivity to your tankless, combi-boiler, or any Navien system you will have the convenience and control of all your systems right in the palm of your hand.
*Existing installations may require the purchase of a new main PCB and front control panel.
