Cascade Up to 16 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 16 units are generating hot water as needed. The Navien cascading system also balances out the workload of each unit for longer life.

NaviLink Optional Wi-Fi Remote Control System.

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.

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.
