About the Torus
RBI's live Torus page (2026-09-09) prints 300–4,000 MBH, 97.5%* AHRI Boiler Efficiency, a 316L stainless-steel watertube heat exchanger and full modulation at 10:1*, with '*Efficiencies & Turndown vary by unit size' printed on the page.
The page describes a pressure-driven mixing system with no moving parts that provides 'a reliable maximum of 10:1 turndown, without lowering the CO2% while avoiding nuisance ignition lockouts', on the HEATNET 3.0 touchscreen cascade control platform with Modbus, LonWorks and BACnet BMS integration.
The Torus occupied the mid-size condensing range between the Encore and the FlexCore. No official Canadian-sales statement was found, so canadianStatus stays unknown.
