NPE-A2 Advanced Condensing Tankless Water Heater
Navien NPE-A2 simply a smarter hot water system for today’s life styles
- 2″ PVC up to 75 feet
- High efficiency up to 0.95 UEF and up to 15:1 TDR
- Durable dual stainless steel heat exchangers
- EZNav™ multi-line control with built-in intuitive software
Built-in recirculation system
Navien’s patented ComfortFlow® system is the first to include a buffer tank, recirculation pump and fine-tuned controls into a tankless water heater, resolving the cold-water sandwich effect* and issues of minimal flow rates commonly found in other tankless water heaters.
* The “cold-water sandwich effect” is the undesired introduction of cold water into the hot water supply line on occasions of frequent on/off operations. (Measure Guideline : Transitioning to a Tankless Water heater, DOE, Sept.2012).
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.
Cascading up to 32 units and common vent up to 12 units
Cascade up to 32 units with Navien Ready-Link® technology.
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.
