Lochinvar · Series
The Noble is Lochinvar's compact fire-tube series in three mountings — NKB heating boilers (80-199), NKC wall-hung combis (110-199) and NCF floor combis (110-199) — all rated 95.0% AFUE, sold under the Epic name in Canada and run by the SMART CONTROL with text-name faults.
Series facts
95.0% AFUE across the Noble series per the I&O ratings table.
The Noble fire-tube line splits by job: the NKB80-199 models are wall-hung heating-only boilers with 1" sweat water connections and no domestic hot water, while the NKC110-199 wall-hung combis and NCF110-199 floor-standing combis add on-demand DHW through 3/4" DHW connections. Every model in the I&O ratings table is 95.0% AFUE, and the combi product pages describe the SMART CONTROL's diverter arrangement as eliminating the cold-water "sandwich" between DHW draws.
Lochinvar's residential boilers page marks the Noble wall-mount boiler, combi wall mount and combi floor mount as "Sold as Epic® in Canada," while the manuals and product pages themselves use the Noble name. The SMART CONTROL reports faults as text-name messages on the boiler interface — such as Flame Fail Ign, Air Pressure Switch or Combi Sensor Fault — rather than numeric codes, and Boilers.ca documents each against the Noble I&O manual's troubleshooting chart. Product pages print a 10-year heat exchanger and 5-year parts warranty, and the 110 combi pages quote DHW of up to 2.6 GPM at a 77°F rise.
Highlights

Services for Lochinvar boilers
The NKB (80-199 MBH) is a wall-hung heating-only boiler for systems with an indirect tank. The NKC and NCF are combis that produce domestic hot water on demand — the NKC hangs on a wall and the NCF stands on the floor — and both span 110-199 MBH.
Lochinvar's residential boilers page labels each Noble entry "Sold as Epic® in Canada." The product pages and the Noble installation manual use the Noble name, and Lochinvar's Canada English pages are identical to its United States pages.
The NKC110 and NCF110 product pages quote DHW of up to 2.6 GPM at a 77°F temperature rise, and Lochinvar's combi marketing copy describes DHW of up to 4.8 GPM. Actual delivery depends on input, incoming water temperature and the draw pattern.
