New Product: High-Efficiency Noble Residential Boilers

Value Priced at the Top of its Class

Lochinvar’s Noble Boiler is a leader in standard residential boilers, and the best option to step up from a traditional cast iron boiler to a high-efficiency design. Designed, engineered and assembled in the USA, the Noble Boiler delivers performance far beyond other value-priced residential boilers in its class. It offers several features first pioneered by Lochinvar’s KNIGHT boiler—the top selling boiler since 2005 and still the leading premium solution in hydronic heating. And, with Porter Pipe’s inventory of Noble Boiler parts, you’ll never have to worry about waiting on a replacement part to get the job done.

Noble Features

Advanced Electronic Control

The backlit, user-friendly LCD display provides diagnostic information and system status in real words, not codes. The Set-Up Wizard display makes it simple to set system parameters in just minutes.

Fire-Tube Heat Exchanger

Low pressure drop saves on pump operation costs and provides installation flexibility, while stainless steel fights off corrosion.

Universal Vent Connector

Multi-material connector allows either PVC, CPVC, polypropylene or stainless steel connection directly to the appliance without adaptors. Noble also has a built-in combustion analyzer port.

Direct Venting Up To 100 Feet

Noble offers five venting options for tremendous installation flexibility. It permits direct-vent air intake and exhaust runs up to 100 equivalent feet using either PVC, CPVC, polypropylene or AL29-4C stainless steel vent pipe.

10:1 Turndown Ratio

Noble operates as low as 10% of the maximum firing rate, preventing on/off short cycling at the lowest DHW demands or small heating demands.

Advanced Negative Regulation Technology

Negative regulation technology eliminates mechanical dampers as it automatically adjusts fan speed to ensure the correct volume and mix of fuel and air throughout the firing range.
