With Navien cascading technology, when a boiler gets up to 80% of its capacity the next unit will start to help meet the heating system requirements.
This boiler sequencing will continue until the heating load is fully satisfied. The Navien cascading system also balances out the run hours of each boiler 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.
* Existing installations may require the purchase of a new main PCB and front control panel.
