RBI (rbiwaterheaters.com) is a commercial boiler and water-heater manufacturer in Westfield, Massachusetts, and an official Mestek, Inc. company: the site footer prints 'Mestek, Inc. © Copyright 2026' with the same 260 North Elm St., Westfield, MA 01085 headquarters address that mestek.com lists. RBI shares that address with Smith Cast Iron Boilers.
The live RBI site (verified 2026-09-09) lists its commercial boilers as Dominator, Dominator LCD, Encore, FlexCore, Futera II, Futera III, Futera Fusion, Futera XLF, Infinite Energy², Spectrum and Torus. The condensing family prints: FlexCore (2,000–6,000 MBH, 96.8% AHRI*), Torus (300–4,000 MBH, 97.5%*), Encore (350–850 MBH, 98.2%*), Futera Fusion (1,750, 2,000, 3,500 and 4,000 MBH, 95.3% AHRI boiler / 98% AHRI water heater) and Infinite Energy² (199–1,000 MBH, 95.2% AHRI, up to 20:1). The copper-fin family prints Futera III (page range 500–1,999 MBH, 85.6% AHRI, 4:1) and Futera XLF (2,500–10,000 MBH, 85.9% AHRI, 5:1), plus the Futera II, Dominator and Spectrum listings.
RBI had been unreachable in the earlier research session; on 2026-09-09 the site responded and Boilers.ca re-verified its RBI facts against the live product pages, the published ratings and dimensions tables and the official Mestek literature library (literature.mestek.com). No official Canadian availability statement was found on the live pages, so canadianStatus remains unknown.
