About the Adapt+ Premium condensing tankless
The Adapt+ is the premium condensing tankless line on the John Wood Canadian site, described there as A. O. Smith's Adapt+ platform. John Wood publishes 0.95 UEF and ENERGY STAR certification for the line, a 15-year limited residential heat-exchanger warranty with 5 years on parts, and field convertibility from natural gas to propane with the kit included with the unit.
John Wood states that the patented X3 scale-prevention technology helps the units maintain like-new performance longer while eliminating the need for annual descaling. That is the manufacturer's claim about the feature; this site records it as published and does not present it as an independent test result, and the maintenance requirements of a specific model are confirmed from that model's own manual.
The line is documented here at family level because the per-model inputs, flows at temperature rise and Canadian availability sit in the official spec sheet, which is linked for verification. Whether CANRO stocks a given Adapt+ model for a project is confirmed at consultation, and CANRO names John Wood among the brands it services on its own pages.
