Description
Lochinvar is proud to introduce the Noble boiler—our newest high-efficiency residential boiler. Noble, Lochinvar’s first-ever value-inspired boiler, comes with many of the industry-leading features you would expect to find in a Lochinvar residential boiler. With the addition of the Noble fire-tube boiler, Lochinvar now offers one of the broadest lines of residential condensing boiler products in the industry.

Designed, engineered and assembled in the USA, the Noble boiler delivers performance far beyond other value-priced residential boilers in its class. It touts several of the industry-leading features first pioneered by Lochinvar’s KNIGHT boiler—the top-selling residential boiler since 2005 and still the leading premium solution in hydronic heating.

Features:
  • UNIVERSAL VENT CONNECTOR: Multi-material connector allows either PVC, CPVC, polypropylene or stainless steel connection directly to the appliance without adapters. NOBLE also has a built-in combustion analyzer port.
  • DIRECT VENTING UP TO 100 FEET: 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.
  • ADVANCED NEGATIVE REGULATION TECHNOLOGY: Safely and reliably operates with supply gas pressure as low as 4 inches water column. Its negative regulation (neg/reg) 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.
  • FIRE-TUBE HEAT EXCHANGER: Low pressure drop saves on pump operation costs and provides installation flexibility, while stainless steel fights off corrosion.
