Industry’s largest turn down ratio in the NHB-150 providing ease of installation with multiple zones while maintaining high operational efficiencies.
The integrated control provides industry leading options and features in the boiler operation parameters, including:
Navien’s Manifold kits are ideal for hydronic space heating applications. With these manifolds, we have done the piping work for you. Both primary and secondary loop manifold kits are designed to work on all NHB models for fast and clean installations. All you need to add is your own appropriately sized pump
With our cascading technology, when a unit gets up to 80% capacity determined by the supply and return temperatures, the next unit will enable to help meet the hydronic space heating requirements.
This hydronic space heating requirement and demand ratio will continue until all units are generating the needed hydronic space heat up to the maximum cascaded capacity. The Navien cascading system also balances out the workload of each unit for longer life. The NHB is dual certified for single and 2-pipe venting applications.
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.
