Brand hub
Rheem's commercial product tree on rheem.com is water heating and HVAC — there are no commercial boiler lines on it, and residential boilers are the only boiler pages the site publishes. Official Rheem-family commercial boilers are the Raypak lines; Rheem/Ruud commercial tankless water heaters are documented here as DHW-only series.

Rheem's official commercial category (/products/commercial/) is commercial water heating and commercial heating-and-cooling equipment: tankless gas and electric, heat-pump water heaters, commercial tanks, and packaged/split HVAC — no boiler category exists in the commercial tree. Boilers on rheem.com appear only under the residential water-heating categories, which are outside this commercial hub's scope. Ruud's commercial tree mirrors it (commercial water heating and commercial heating/cooling), also without a boiler category.
The official link between the brands comes from Raypak, not Rheem: Raypak's company-history page states Raypak is 'a member of the Rheem family of brands' and that 'Raypak officially became part of the Rheem family of brands'. Commercial boiler specifications therefore belong to Raypak's lines (XVers, XTherm, MVB, Hi Delta, Delta Limited), and Boilers.ca answers 'Rheem/Ruud commercial boiler' questions by pointing to those Raypak hubs.
The commercial tankless line is official and documented: the IKONIC Commercial Condensing Tankless, sold as Rheem RTGH-CS11i / RTGH-CSR11i and Ruud RUTGH-CS11i / RUTGH-CSR11i. It is a condensing tankless water heater for domestic hot water (11,000–199,900 BTU/h per unit, 11.2 GPM, 0.96 UEF), not a boiler, and Boilers.ca publishes it as a DHW-only series with four models. No Canadian statement was captured on the Rheem or Ruud commercial pages, so canadianStatus is unknown.

At Raypak: the official Raypak company history says Raypak 'officially became part of the Rheem family of brands', and Raypak's commercial hydronic boiler lines (XVers, XTherm, MVB, Hi Delta, Delta Limited) are the Rheem-family commercial boiler offering.
