About John Wood
John Wood is one of the A. O. Smith family's Canadian brands, closely related to GSW, with atmospheric, direct-vent, power-vent and power-direct-vent gas tanks, Envirosense high-efficiency and Polaris families, and the Adapt+ Premium, Adapt SC and Adapt NC tankless lines.
The Canadian site was re-verified on 2026-09-19 and now serves its product pages as readable HTML: the Adapt+ Premium condensing tankless line is published there with 0.95 UEF, ENERGY STAR certification, field convertibility between natural gas and propane, and a 15-year residential heat-exchanger warranty, and the ProLine atmospheric family with the Flame Guard flammable-vapour-ignition-resistant safety system and LED diagnostics. Those facts are recorded on the John Wood series page.
WaterHeating.ca adds John Wood series and model records as their Canadian sheets are verified; availability for a specific model is confirmed at consultation. CANRO names John Wood among the brands it services on its own pages.
