NAVIEN - High Efficiency Combi Boiler

NAVIEN NCB -E Combi Boilers

Description

Navien NCB-E is the first high efficiency condensing combination boiler with the capacity to supply both heat and domestic hot water for larger homes — enough hydronic heat for a whole house, plus hot water to run two showers and a dishwasher all at the same time.
The Navien NCB-E saves installation time and reduces call backs. In addition, the NCB-E takes up 80% less space than a traditional floor standing boiler and tank water heater. Your customer now has more room, saves energy and enjoys all the hot water they need, whenever they want it.

    Allied Engineering Compact Miniseries Hydronic Boiler

    Features and Components

    1. Automatic Vent Damper Supplied with all boilers, the vent closes when the boiler is not firing preventing heat loss and conserving energy.
    2. Standard Draft Hood Prevents downdraft and exhaust flue gases through the chimney. Includes a quick connect Blocked Vent Safety Switch.
    3. Circulator/Pump and Cast-Iron Adapter Included on “PS” models and supplied wired and mounted or wired and loose if specified.
    4. Long-Life Stainless-Steel Burners Scientifically designed for quiet operation and maximum efficiency. Burner drawers slide out easily for inspection and service when required.
    5. Combination Gas Control Controls include a manual valve, two automatic operators, and servo pressure regulator to provide dual-seated 100% safety shutoff.
    6. Steel Fin-Tube Heat Exchanger Our unique double pass design uses 1/2” fin spirally and continuously welded on 2” OD SA 178A industrial steel boiler tube to maximize heat transfer area.
    7. Temperature/ Pressure Gauge Factory supplied gauge indicates operating temperature and pressure of the boiler.
    8. Integrated Boiler Control Advanced Honeywell® control with electronic spark ignition, thermal purge, and limit-rated water temperature control. Simple programming and LED display for quick installation and diagnostics.
    9. Flame Roll-out Safety Switch For added protection, the safety device shuts the boiler down.
