Description for Bradford White M-I-5036FBN

PLEASE NOTE: This water heater cannot be sold to residents of certain southern California zip codes due to Air Quality Regulations. To view a list of zip codes where this heater cannot be installed, click here.

This Bradford White water heater utilizes a draft diverter and is atmospherically vented. It is perfect for many standard water heating applications.

Features:

  • Bradford White ICON System - Intelligent gas control with proven millivolt powered technology and built-in piezo igniter. A standard, off the shelf thermopile converts heat energy from the pilot flame into electrical energy to operate the gas valve and microprocessor. No need for external electricity.
    • Enhanced Performance - Proprietary algorithms provide enhanced First Hour Delivery ratings and tighter temperature differentials.
    • Advanced Temperature Control System - Microprocessor constantly monitors and controls burner operation to maintain consistent and accurate water temperature levels.
    • Intelligent Diagnostics - An exclusive green LED light prompts the installer during start-up and provides ten different diagnostic codes to assist in troubleshooting.
    • Pilot On Indication - Flashing green LED provides positive indication that pilot is on.
    • Separate Immersed Thermowell - High strength advanced polymer composite thermowell provides isolation between electric temperature sensor and surrounding water. No need to drain the tank when removing gas valve.
  • Advanced ScreenLok® Technology Flame Arrestor Design - Flame arrestor is designed to prevent ignition of flammable vapor outside of the water heater.
  • Resettable Thermal Switch - Proven and reliable bimetallic switch prevents burner and pilot operation in case of ongoing flammable vapor burn inside of the combustion chamber or restricted air flow.
  • Maintenance Free - No regular cleaning of air inlet openings or flame arrestor is required under normal conditions.
  • Sight Window - Offers a view into the combustion chamber to observe the operation of the pilot and burner.
  • Factory Installed Hydrojet® Total Performance System - Cold water inlet sediment reducing device helps prevent sediment build up in tank. Increases first hour delivery of hot water while minimizing temperature build up in tank.
  • Vitraglas® Lining - Bradford White tanks are lined with a exclusively engineered enamel formula that provides superior protection from the highly corrosive effects of hot water. This formula (Vitraglas®) is fused to the steel surface by firing at a temperature of over 1600ºF.
  • 1" Non-CFC Foam Insulation - Covers the sides and top of tank, reducing the amount of heat loss. This results in less energy consumption, improved operation efficiencies and jacket rigidity.
  • Pedestal Base.
  • Water Connections -3/4" NPT factory installed true dielectric fittings.
  • Factory Installed Heat Traps.
  • Protective Magnesium Anode Rod.
  • 3x4 "Snap Lock" Draft Diverter - Allows either 3" or 4" vent connections with inputs of 40,000 BTU/Hr or less. Over 40,000 BTU/Hr. has the 4" "Snap Lock" Draft Diverter.

I had a Bradford Defender installed in my hair salon over a year ago and the pilot light goes out at least once a week. The final straw was Saturday, December 22 which is the busiest day of the year and once again NO HOT WATER!!! .......can you imagine having a hair salon in the Northeast in December with no hot water!!? This heater has repeatedly hurt my business and my plumber will be removing this relatively new water and installing a more reputable product this week. Very disappointed!

Great water heater. Arrived in great shape, took a little longer than anticipated for shipping, but all in all a great buy. Best price I could find by far and very easy to install. Took about an hour for piping hot water, and have had to turn it down twice more! Heats very quickly with plenty in reserve. We took three showers back to back to back and did two loads of laundry and still had hot water to spare. Thanks PexSupply!

Appliance was easy to install & functioned properly out-of-the-box. Three inches taller but identical footprint from AOSmith 40gal appliance it replaced meant modifying flue vent (without difficulty). Tank debris accumulated at & plugged faucet aerators; an experienced plumber might have anticipated this potential, removed aerators & flushed a single faucet.

Quick shipping and it was very easy to install. I had a very similar Bradford when I built my house 12 years ago but it started leaking and I had a small leak and replaced it before a bigger leak. Instillation was a breeze, I did it myself. Hot water has never been hotter!

Bought this to replace the same unit that was 14 years old. The old one still worked fine, but I don't like to wait until the last minute. The new unit it more efficient. The controller fires up earlier and stop sooner keeping the set temperature better.
Plumber swapped the units in less than 2 hours.
Order and shipping where quick and easy. Unit arrived on a pallet in perfect shape.

Comments about 50 Gallon - 40,000 BTU Defender Safety System Atmospheric Vent Energy Saver Residential Water Heater (Nat Gas):

Water heater arrived quickly and packaging appeared in good shape on arrival. After unboxing unit, found the top of the heater to be dented. Agreed to a discount with Pex for damage and unit was then installed. Could not get relief valve threaded connection to seal properly(used Teflon tape). After removing it, saw a damaged thread on it and had to replace with another psv. I needed hot water so didn't have luxury of time to get Pex to send replacement. Install was easy. Everything as per instruction booklet to ignite. Heats well. So far so good.

    Q:

    What specifically do you need to buy or install to get a 10 year warranty? Who would I contact if warranty service is needed since you have no local outlets?
    Asked on 6/21/2012 by John from Hopkins, MN

    2 answers

    • VERIFIED BUYER

      A:

      This question needs two answers.
      1. The specifications page for your 50 gallon heater product (
      http://www.pexsupply.com/Bradford-White-M-4-5036FBN-50-Gallon-40000-BTU-Defender-Safety-System-Energy-Star-High-Efficiency-Residential-Water-Heater-Nat-Gas
      )shows a standard warranty covering a 6 year period. The page also
      offers you a web link to another product description telling you about a
      second product you can buy which extends the (standard) 6 year warranty
      to an extended, 10-year warranty (personal comment - that adds 4 years
      to your warranty coverage.)
      Make absolutely sure your model number is on the 'authorized' list.
      Go HERE (
      http://www.pexsupply.com/Bradford-White-238-43329-00-10-Year-Warranty-Upgrade-Kit-Level-1
      ) for details on what you need to order, what it will cost, etc etc. I
      see a cost of 141.95 for that 4-year extension.
      2. At the bottom of that page, below the listing of qualified model
      numbers, both Gas and Electric, which you can purchase the extended
      coverage, you will see " For additional warranty information, please
      visit Bradford White's Warranty Information Page
      <http://www.bradfordwhite.com/warch.asp>. " That page is your
      "official" statement for warranty coverage, disallowed items not
      covered, and most important, the final statement at the bottom of the
      Warranty Information Page:

      A:

      For a 10 year warranty water heater you need to buy the water heater that
      states it does have a 10 year warranty. Simply register the water heater ad
      install date by mail or PC. Doing that is all you need to do. If there is a
      problem you would call the manufacturer and explain the problem. They have a
      network of plumbers or heating contractors that would come to the house to
      resolve the issue. As for products I like the Bradford, just made better,
      but that is my preference.

      Our gas supply line is 13.5 inches from the floor to the center of the gas pipe. Our water heater sits on top of a drain pan and is further shimmed up with 1/2 inch plywood (possibly done so as not to have to cut or adjust the gas pipe). The gas feedline to the burner is 3 1/4 inches from the top of the drain pan surface. Hope this helps.

    Q:

    what does "atmospheric vent" ?
    Asked on 4/11/2012 by quan nguyen from Alameda, CA

    4 answers

    • CUSTOMER CARE

      A:

      Atmospheric vent units (also know as gravity vent, chimney vent, or standard vent) rely on the natural process of exhaust gases rising through a chimney. Power vent and direct vent units, on the other hand, use blower fans to force exhaust gases away from the water heater.

      Answered on 4/12/2012 by PexSupply Staff from NY
    • VERIFIED BUYER

      A:

      It means that the exhaust is vented directly into the flue or utility chimney. Does not require a fan to pump the exhaust outside. Take a look at your existing water heater, if you have an aluminum flue heading to the chimney you have an atmospheric vent.

      A:

      Atmospheric vent means ( based on Picture) that it is the traditional
      venting of galvanized pipe to a chimney-not what the higher efficiency units
      with power vents or PVC piping would need

      Answered on 4/13/2012 by Another PexSupply Customer
    • VERIFIED BUYER

      A:

      Google it...here is one definition...
      When
      people talk about atmospheric-vent heaters, or if you see them
      in a company spec sheet, it's referring to the most common type
      of gas water heater out there -- one that has a vent pipe that
      passes straight up through the roof.

      A:

      Energy Factor is an 'artificial index' created to indicate to a buyer/user the effectiveness of a rated product.
      Newly demanded to be provided with appliances and products that consume power/energy to create hot water for your home..... each product design - energy source, insulation characteristics, heat loss through vents, etc., create a unique energy factor for each water heater product. The costs of energy, electric or natural gas or propane, should be factored into analyzing the 'energy factor' to determine the overall cost comparison of operating alternate product solutions and judging the lowest cost in your local community.
      This information may help you....
      http://www.consumerenergycenter.org/home/appliances/waterheaters.html
      from which this following information is taken:
      Understanding The Energy Factor Label
      There is another label on new water heaters listing that unit's "Energy Factor." It's a number with a decimal point, usually listed on a separate tag beside the EnergyGuide.
      The higher the "Energy Factor" number, the more efficient the water heater. Gas water heaters have energy factors between 0.5 to around 0.7. Electric models range from 0.75 to 0.95.
      Those Energy Factor numbers show that electric models make better use of energy, primarily because gas water heaters lose some of their energy up the exhaust vent. However, new gas water heaters boast more efficient combustion than older ones, meaning that less heat escapes up the flue, and less gas is needed to heat the water. Gas efficiency has improved.
      But since electrical energy usually costs three times more than gas, in most of California it's still cheaper to use natural gas, if you have a choice.
      "Energy Factors" vary because different water heaters are made to be more energy efficient. Today's models are better insulated than the ones manufactured years ago. As a result, most cost about 18 percent less to run than older models. The savings are due to reduced heat loss, thanks to the added insulation.
      Return to Top
      It's Your Money
      Whichever type of water heater you buy - either gas or electric - look for a unit with a higher energy factor. It may cost more initially, but the energy (and your money) savings may more than make up for the higher sticker price. Consider the price difference and how long it would take to recover the money through energy savings.
      For example, say a gas water heater with an energy factor of 0.57 sells for $129, while one with an energy factor of 0.61 sells for $145. To begin with, you'll spend $16 more for the model with the higher energy factor, but it will save you almost $11 a year in the natural gas. You have recovered your initial $16 investment within 18 months. Over the estimated life of the water heater, you should save an additional $125.
      Here's a comparison of what various water heaters with different Energy Factors could cost to operate each year, using a consistent price for energy. Note the savings compared to the 0.53 model over the 13-year life expectancy of a water heater. Energy savings are based on the average use of a family of four.
      Energy Factor Energy Cost Each Year Savings Over Life of Appliance
      0.53 $177 $0
      0.57 $166 $143
      0.61 $155 $286
      0.65 $144 $429
      As you can see, spending more up-front for a more efficient water heater - one with a higher Energy Factor - can mean major savings over the life of the appliance!
