Comparison
Verdict in brief
Both are 50 US gallon (189 L) through-the-wall power-vent natural gas storage tanks that need no chimney and run on 120 V, but they are aimed at different loads. The Giant UG50-62 is the high-input version at 62,000 BTU/h with 3/4 in side taps, and Giant does not publish a first-hour rating, recovery rate or energy factor for it. The Bradford White RG2PV50S6N19 is a 40,000 BTU/h unit with a published 78 US gallon (295 L) first-hour rating, 44 US gal/h recovery at a 90 °F rise and UEF 0.72. Choose by whether the job needs the higher input or the published sizing data and the longer vent runs.

“—” 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.
Both are 50 US gallon (189 L) power-vent tanks that draw combustion air from inside the home and force exhaust outside through PVC-family pipe, so neither needs a chimney and both need a 120 V supply for the blower, which means neither heats during a power outage. The difference is the burner. The Giant UG50-62 is the high-input model at 62,000 BTU/h on natural gas and propane; the Bradford White RG2PV50S6N19 is 40,000 BTU/h on natural gas (38,000 BTU/h on propane).
Published data decides how much of the Giant's extra input can be used. Bradford White publishes a 78 US gallon (295 L) first-hour rating, 44 US gal/h recovery at a 90 °F (50 °C) rise and UEF 0.72 under the medium-draw test. Giant publishes capacity and input but no first-hour rating, recovery rate or energy factor for the UG50-62, so the higher input should recover faster in principle, but the delivered volume cannot be read from a published figure and is confirmed in a demand assessment.
Venting is where the models separate on installation. Bradford White publishes maximum equivalent vent lengths of 50 ft in 2 in, 120 ft in 3 in and 200 ft in 4 in, with minimums of 7 ft in 2 in and 15 ft in 3 or 4 in. Giant lists 2 in, 3 in or 4 in ULC S636 PVC, CPVC or polypropylene up to 180 equivalent feet, with the high-input UG50-62 listed in 3 in or 4 in. A long or tightly routed run is checked against the exact manual for the model.
The Giant also carries 3/4 in side taps for combination applications, which Bradford White does not list for the RG2PV50S6N19. Giant states a 6-year inner-tank and 6-year parts warranty and lists an electronic gas control with self-diagnostic capability, a flammable-vapour sensor, a rotatable blower and a TankSaver design; Bradford White lists a 10-year-warranty variant of the same tank, the RG2PV50S10N19. Whether CANRO supplies either model for a given job is confirmed at consultation, and no price is published here.
Giant · Gas storage tank
The Giant UG50-62 is a 50 US gallon (189 L) power-vent natural gas or propane storage water heater with a 62,000 BTU/h input, a motorized blower for side-wall venting, 3/4 in side taps and a 6-year tank and parts warranty, made in Canada by Giant.
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.
Both are 50 US gallon (189 L) power-vent gas tanks needing no chimney. The Giant is the high-input 62,000 BTU/h version with 3/4 in side taps and no published first-hour rating; the Bradford White is 40,000 BTU/h with a published 78 US gallon (295 L) first-hour rating and UEF 0.72.
Bradford White publishes up to 200 ft equivalent in 4 in pipe (120 ft in 3 in, 50 ft in 2 in). Giant lists up to 180 equivalent feet across 2 in, 3 in or 4 in ULC S636 pipe, with the high-input UG50-62 in 3 in or 4 in. The installation manual for the exact model governs.
No. Both force exhaust outside with a blower through PVC-family pipe and take combustion air from the room. Both need a 120 V supply and neither heats during a power outage.
Yes. Giant lists the UG50-62 at the same 62,000 BTU/h on natural gas and propane. Bradford White's propane version is the RG2PV50S6X19 at 38,000 BTU/h. Order the correct fuel version.
A consultation includes a hot-water demand review so capacity is right for your winter, not the brochure's.
