Comparison
Verdict in brief
Both are 50 US gallon (189 L) second-generation Bradford White power-vent gas tanks with the same 40,000 BTU/h input, UEF 0.72 and 2, 3 or 4 in PVC-family venting, so recovery is identical at 44 US gal/h. The short S6N stands 48 3/16 in to the top of the heater in a 24 in jacket and rates 78 US gal first-hour; the tall T6N stands 57 9/16 in in a 22 in jacket and rates 75 US gal. Choose by ceiling height and floor width, not by capacity, which is the same.

“—” means not applicable to that system type or not published by the manufacturer. Flow figures are only comparable at the same temperature rise; UEF values are only comparable within the same draw pattern.
Because the tank, burner and venting are shared, this is a shape decision rather than a capacity one. Both models hold 50 US gallons (189 L) nominal, burn 40,000 BTU/h on natural gas, recover 44 US gal/h (167 L/h) at a 90 °F (50 °C) rise and carry UEF 0.72 under the medium-draw test, below ENERGY STAR's 0.81 threshold for the size. Both use 2, 3 or 4 in PVC, ABS, CPVC or polypropylene under positive pressure with the same maximum equivalent lengths (50 ft in 2 in, 120 ft in 3 in, 200 ft in 4 in) and the same 1/2 in gas and 3/4 in NPT water connections.
The counter-intuitive result is the first-hour rating. The short RG2PV50S6N19 is listed at 78 US gallons (295 L) and the tall RG2PV50T6N19 at 75 US gallons (284 L) at the same input and recovery, because the short form's geometry and dip-tube placement deliver slightly more usable hot water in the test hour. The three-gallon gap is about one short draw, so it rarely decides a replacement on its own.
The dimensions decide it instead. The short S6N reaches 48 3/16 in (1224 mm) to the top of the heater and 56 7/16 in (1432 mm) to the blower, in a 24 in (610 mm) jacket, shipping at 168 lb (76 kg). The tall T6N reaches 57 9/16 in (1462 mm) and 65 13/16 in (1672 mm) to the blower, in a narrower 22 in (559 mm) jacket, at 173 lb (78 kg). A low ceiling favours the S6N; a narrow door or closet favours the T6N, which needs about 66 in of ceiling clearance including its blower.
Both are Defender Safety System flammable-vapour-ignition-resistant tanks with electronic ignition and no standing pilot, both need a 120 VAC, 3.1 A supply for the AquaVENT blower and ICON System control, and so neither provides hot water during a power outage. Anode inspection every two years applies to both, and the warranty excludes labour and anode consumption. Whether CANRO supplies a given form for a job is confirmed at consultation.
Bradford White · Gas storage tank
The Bradford White RG2PV50S6N19 is a 50 US gallon (189 L) through-the-wall power vent natural gas storage water heater with a 40,000 BTU/h input, 78 US gallon first-hour rating and UEF 0.72, sold in Canada under the current 19-suffix model numbers. It needs no chimney.
Bradford White · Gas storage tank
The Bradford White RG2PV50T6N19 is a 50 US gallon (189 L) tall through-the-wall power vent natural gas storage water heater with a 40,000 BTU/h input, 75 US gallon first-hour rating and UEF 0.72, sold in Canada under the current 19-suffix model numbers. It is the standard 50-gallon answer for homes without a chimney.
Bradford White lists the short RG2PV50S6N19 at 78 US gallons and the tall RG2PV50T6N19 at 75 US gallons at the same 40,000 BTU/h input and 44 US gal/h recovery. The difference comes from tank geometry and dip-tube placement, not from a bigger burner.
The short S6N reaches 56 7/16 in to the top of its blower and the tall T6N 65 13/16 in, so plan on about 66 in of clearance for the tall form. Both need room for the vent run and service access.
Yes. Both are on Bradford White's Canadian residential gas page and Canadian spec sheet C1261, which prints them without the 19 catalog suffix as RG2PV50S6N and RG2PV50T6N. Bradford White sells only through wholesalers, so they are supplied and installed by contractors such as CANRO.
A consultation includes a hot-water demand review so capacity is right for your winter, not the brochure's.
