About Lochinvar

Lochinvar, LLC traces its heritage to the Walter Vallett Company founded in 1939, per Lochinvar's own pages, and is headquartered in Lebanon, Tennessee (the address printed on its product summaries). The boilers documented on Boilers.ca are the residential lines served from lochinvar.com: the Knight fire-tube boilers (wall-hung WHB055-399 and floor KHB055-285 with the SMART SYSTEM control), the Noble fire-tube boiler and combis (NKB, NKC and NCF with the SMART CONTROL system) and the non-condensing Solution heating boiler, which is still listed alongside them.

Lochinvar sells into Canada without a separate Canadian website: its Canada English (en_CA) product pages are byte-identical to the United States pages and still print "Destination Country: US" in the specification blocks, and the same residential page that introduces the Knight and Noble marks the Noble models "Sold as Epic® in Canada." Canadian availability is supported by Lochinvar's own international sales page, which lists AQUA-TECH SALES AND MARKETING, Inc. (Burlington, Ontario, with a British Columbia contact) and TRILEX (Quebec) as its Canada distributors.

Lochinvar's installation manuals treat Canada directly: each carries the B149.1 installation code and CSA C22.1 as compliance references for Canada, and each requires ULC S636-certified plastic venting for Canadian installations. Lochinvar also hosts French-Canadian (FRE-CAN) editions of the Knight KHB/WHB and Noble installation manuals plus Canadian English and French editions of its Residential Consumer Guide, and it publishes boiler warranty sheets bilingually on the same product pages served to Canada.

Lochinvar's control displays identify faults by text name rather than numeric code: the Knight SMART SYSTEM and Noble SMART CONTROL screens show messages such as Flame Fail Ign, Gas Pressure SW or Outlet ARHL, and Boilers.ca documents those names against the fault tables in Lochinvar's own service literature. Beyond the residential lines, Lochinvar sells commercial boilers such as the Crest with Hellcat combustion technology, which Boilers.ca mentions only as the brand's commercial hub.

Frequently asked questions

Why is the Lochinvar Noble sold as "Epic" in Canada?

Lochinvar's own residential boilers page marks the Noble wall-mount boiler, the Noble combi wall mount and the Noble combi floor mount as "Sold as Epic® in Canada" on the same page where it lists the Knight. The product pages and manuals themselves keep the Noble name, and the Canada English pages are identical to the United States pages.

Do Lochinvar boilers display numeric error codes?

No. The Knight SMART SYSTEM and the Noble SMART CONTROL displays show text-name fault messages such as Flame Fail Ign, Gas Pressure SW, Outlet ARHL or Delta T High rather than numeric codes. Boilers.ca documents each text fault against the fault table in Lochinvar's manual for the correct series.

Does ROMA Heating & Cooling supply or service Lochinvar boilers?

ROMA Heating & Cooling installs and services gas boilers across Greater Vancouver. Whether a specific Lochinvar model is supplied for your project is confirmed at consultation; Boilers.ca does not claim stock or availability for any brand.
