Bradford White RG2DV50S6N-FLX 50 Gallon, Short, Direct Vent Water Heater, Natural Gas


The Bradford White RG2DV50S6N is a 50 gallon direct vent hot water heater. It uses a co-axial vent pipe with an inner dimension of 3" and an outer dimension of 5". The pipe inside a pipe configuration allows for air intake through one pipe (the outer pipe) and exhaust/combustion directly back outside though the other (the inner pipe). The hot water heater comes with a flexible vent kit.


This tank is 72-1/2" from the floor to the C/L of Vent and the floor to the top of the heater is 59-3/16". The jacket diameter is 22" wide, the depth of the heater is 31". This hot water heater features an input of 42,000 BTUs, and has a First Hour Rating or First Hour Delivery of 77 gallons.


Basically, the First Hour Rating means how much hot water the hot water heater can deliver in an hour of use, starting with a fully heated tank. It does not mean that the hot water will last for one hour. As the cold water enters the tank it is heated, the faster you use your hot water, the faster your water will become tepid and then cold. However, depending on your temperature set point and your household's water use you can calculate how much hot water you need during your busiest hour. As you use the water in the tank, it is continuously being replenished and heated.


The Uniform Energy Factor (UEF) is used to determine the energy efficiency of the hot water heater. Recover efficiency, stand-by loss and cycling loss are all included in the energy factor. Typically, the higher the energy factor, the more efficient the water heater. Cost of fuel however, will have an impact on annual operating costs.


An example of a 88 gallon peak demand might look like this:

  • 4 showers (10 x 4 = 40 gallons)
  • 1 bath (15 x 1 = 15 gallons)
  • 2 shaves (2 x 2= 4 gallons)
  • 3 hand dishwashing (4 x 3 = 12 gallons)
  • 1 meal prep (4 x 1 = 4 gallons)
  • 1 dishwasher run (6 x 1 = 6 gallons)
  • 1 load of laundry (7 x 1 = 7 gallons)

This household would probably want a hot water heater with a first hour rating of between 86 and 90 gallons.


Another important feature when choosing a hot water heater is the Recovery Rise. A 90° recovery rise for this tank is about 45 gallons per hour. All Bradford White hot water heaters are NAECA Compliant.

The Bradford White Defender Safety System is designed to be the safest, most reliable flammable vapor ignition resistant system in the industry meeting all the requirements set forth by the American National Standards Institute (ANSI). The Defender Safety System features ScreenLok Technology flame arrestor. The louvered flame arrestor design increases the speed of incoming combustion air and creates a vector effect inside the combustion chamber when flammable vapors are ignited, preventing flames from traveling back through the flame arrestor and outside the water heater. Other features include Resettable thermal switch, virtually maintenance free.

ICON Control System is included on all Bradford White Residential and Light Duty Commercial Water Heaters. Features of the ICON System include:

  • Advanced Temperature Control System - A microprocessor constantly monitors and controls burner operation to maintain consistent and accurate water temperature levels
  • Exclusive Performance Software
  • Intelligent Diagnostics for installers with status indicator
  • Pilot-On-Indication
  • Millivolt Powered - No external electricity required
  • Separate Immersed Thermowell - No need to drain the tank when removing or replacing the gas valve
  • Integrated Piezo Igniter

Hydrojet® Total Performance System: The Hydrojet® Total Performance System is a cold-water inlet tube that was especially engineered to reduce costly sediment buildup and create more thorough mixing of incoming water with stored water. Because of more efficient mixing, extreme temperature differences throughout the tank are greatly reduced. Water Heaters with the Hydrojet Total Performance System don't have to work as hard or as often to maintain a maximum supply of hot water at the desired temperature. They heat water faster and use less energy to do it. And, it’s standard equipment on all Bradford White top connect residential water heaters.

Vitraglas® The World's Best Enamel Tank Lining: Bradford White water heater tanks are protected from the corrosive effects of hot water by an exclusive enamel lining. The exclusive Vitraglas enamel lining is uniquely formulated and applied to the interior of the water heater tank.

Our test results prove that Vitraglas provides unsurpassed protection against failure when compared to other water heater linings.
