Description for Bradford White M-1-TW-40S6FBN

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.

The TTW1® model is power vented for positive exhaust. It offers greater installation flexibility with the ability to vent through a wall or roof, with either 2 or 3 PVC, ABS or CPVC pipe.

Features:

  • ENERGY STAR® Qualified - These models qualify for the January 1st, 2009 minimum ENERGY STAR® EF requirement, as well as most utility rebate programs.
  • Advanced ScreenLok® Technology Flame Arrestor Design - Flame arrestor is designed to prevent ignition of flammable vapor outside of the water heater.
  • Flammable Vapor Sensor - Electronic sensor prevents burner operation if flammable vapors are detected. The sensor will also prevent operation if there is ongoing flammable vapor burn inside the combustion chamber.
  • 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. This increases first hour delivery, while minimizing temperature build up at top of tank.
  • Vitraglas® Lining - Bradford White tanks are lined with an exclusively engineered enamel formula that provides superior tank 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 1600° F.
  • Power Vented Water Heater - Designed for installations where atmospheric units cannot be used. Exhaust gases are vented under positive pressure directly out of the building through the roof or the wall.
  • Powerful Blower Motor - Our significantly quiet design has greater resistance to outside winds and the power to vent in many difficult venting situations.
  • Honeywell Self Diagnostic Electronic Gas Control - Intelligent gas control with spark to pilot ignition system eliminates the constant burning pilot. This results in savings of pilot gas during stand by periods (120 V.A.C.).
    • 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 accurate and consistent 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.
  • Horizontal and Vertical Venting - With 2" or 3" PVC, ABS or CPVC (Maximum equivalent vent length on reverse side).
  • 1" Non-CFC Foam Insulation - Covers the sides and top, reducing the amount of heat loss. This results in less energy consumption, improved operation efficiencies and jacket rigidity.
  • Water Connections - 3/4" NPT factory installed true dielectric fittings.
  • Factory installed Heat Traps - Design incorporates a flexible disk that reduces heat loss in piping and eliminates the potential for noise generation.
  • Protective Magnesium Rod.
  • Pedestal Base.
  • T&P Relief Valve - Included.
  • Brass Drain Valve - Durable tamper proof design.

PLEASE NOTE: The product weighs 135 lbs. and may require the use of a
lift gate.
If you do require a lift gate at your delivery, you'll have the option to add this FREE of charge when you checkout.

Great quality

By JC Mark

Verified Buyer

Comments about 40 Gallon - 40,000 BTU Defender Safety System TTW1 Power Vent Energy Saver Residential Water Heater (Nat Gas):

Water heater arrived within 3 days with regular ground. Came neatly on skid, strapped down, no scratches or tears. All parts were inside. Install was smooth, works with 2" or 3" PVC vent pipe. Fan is a little quieter than previous model. Only thing they changed was no stand (so unit is like 2"-3" shorter) and the fan exhaust is on the left as opposed to my old Bradford, which had it on the right. Overall very happy with the product!

After much research I went with the Bradford White and so far I could not be happier. Easy installation, fired right up and working like a charm. The blower is a bit noisy, but nothing that I'm bothered by since it's in the basement.

I have just replaced my old Bradford White after
20 years of service. It was still running perfectly, but I must admit I was a lttle nerves after that amount of time that it might stop running. I therefore ordered another. If this one lasts as long as my last one I will be very, very happy.

Comments about 40 Gallon - 40,000 BTU Defender Safety System TTW1 Power Vent Energy Saver Residential Water Heater (Nat Gas):

Install went smoothly and startup was easy: filled with water, turned on the gas and the power switch - that simple.
Unit has good quality features: a brass ball valve for draining and quick plug connections on the fan unit will make servicing easier (hopefully not soon!)
Another plus is that a full service manual is available on the BW website.

Comments about 40 Gallon - 38,000 BTU Defender Safety System TTW1 Power Vent Energy Saver Residential Water Heater (LP Gas):

This unit is an updated model of the water heater I replaced. It was very simple to install, as the only changes were a slight height adjustment, and the power vent outlet being on the opposite side. The last one I had lasted 14 years. If I can get even close to that from this new unit, it will have been well worth it.

Our new water heater have been doing its job now for 2 weeks. Instalation was easy, and got instant approval from the local gas company. So far, so good as far as Bradford White is concerned. The best part about the experience of buying a water heater sight unseen over the internet has been dealing with Pex Supply and their contracted transportation partner. A+ all the way. Fast service supported by excellent communication. Higly recommended!!!

So far so good

By Plumb Crazy Bob

from Nashua, NH

Verified Buyer

Comments about 40 Gallon - 40,000 BTU Defender Safety System TTW1 Power Vent Energy Saver Residential Water Heater (Nat Gas):

Even though this was the water heater installation from hell (nothing to do with the water heater, I moved its location) the water heater works very well. It is relatively quiet (although there is more vibration from the blower than I expected) and heats water much more quickly than the old water heater ever did, even new.

I wedged the 2" PVC pipe for the flue in a cut through the floor [right above the water heater] making a tight fit. I hadn't thought about expansion and contraction of the PVC and its creaking will take some getting used to (my furnace is also vented via 2" PVC and I've never heard it do this but it is free to move everywhere so it never occurred to me that this would be a problem).

One word of caution though. If you are going to install this using CPVC pipe, remove the "heat trap" insert in the nipples or you will go crazy trying to stop a leak that cannot otherwise be stopped. The CPVC fitting seals with a rubber washer to the top of the nipple and the insert does not allow a tight seal. I was about to change to a copper fitting when I noticed the heat trap rotated within the nipple. I pulled it out and all was well! (see picture below)

  • 40 Gallon - 38,000 BTU Defender Safety System TTW1 Power Vent Energy Saver Residential Water Heater (LP Gas)

    Q:

    what is the purpose for the power vent?
    Asked on 3/4/2014 by Brad from York, Pa

    1 answer

    • VERIFIED BUYER

      A:

      The power vent cools the exhaust from the hot water heater's burner by mixing it with room air. This allows the exhaust vent to be made from PVC rather than metal and the fact that the flow is forced by the blower allows substantial horizontal runs.
      A regular vent requires a metal exhaust vent pipe, either all the way to the outside or (codes permitting) to an existing ceramic / brick flue or chimney. Because the regular vent depends on the fact that hot gases rise to exhaust the combustion products, it cannot have substantial horizontal runs.
      The down sides of the power vent are that it won't work during a power failure (but, then neither will most gas HWH with electronic ignition systems) and the extra air it removes from the area containing the HWH. The later is a problem only in very hot or cold climates where the HWH is inside the heated / air conditioned area. Note that the air loss occurs only when the burner is on which is not a large percentage of the time.

      A:

      Length depends upon pipe diameter and numbr of bends. Try looking it up
      in the owner's manual for the unit.
      I am pleased with my unit.

      Answered on 11/15/2013 by Anonymous
    • VERIFIED BUYER

      A:

      The maximum vent length depends on a number of factors that include whether you use 2" or 3" vent pipe, the number of 90 degree elbows in the line, whether the line runs vertically or horizontally, and the altitude at which the unit is installed. Altitude is a factor above 2500 ft elevation.
      The installation manual is available at http://www.bradfordwhite.com/sites/default/files/product_literature/238-45637-00L.pdf
      See pages 19 - 24.
      With 2" pipe, the maximum run is 50 ft with no elbows (the only way to do this is a vertical run with an open termination, sheltered from the weather). For 3" pipe, it is 100 feet. Subtract 5 ft for each elbow. In a mixed run, the sum of the 2" length, 5 times the 2" elbow count, half the the 3" length and 2.5 times the 3" elbow count should not exceed 50 feet. Vertical runs and horizontal runs that exit near the ground may require multiple elbows to obtain adequate ground or roof clearance and space for snow accumulation in some climates. See the manual for details.

      Answered on 8/1/2013 by clocktool from Minnesota
    • VERIFIED BUYER

      A:

      I do not have a definitive answer to this question, however, I suspect that this is an issue that depends on local building codes rather than having a single answer.
      A simple google query on the topic "raise gas hot water heater above garage floor" brought a number of pages similar to
      http://www.checkthishouse.com/5712/garage-gas-hot-water-heater-raised-above-the-floor-fvir-safety.html
      The basic rationale is that many gas hot water heaters are a possible source of vapor ignition. Vapor producing flammables are commonly found in garages. Think gasoline, paint thinner, propane tanks for gas grills, etc. Spills, leaks, or transfers (filling the mower in the garage) will create vapors. Most, but not all of the vapors are heavier than air so raising the HW Heater allows the vapors to leak out under or around the garage door before rising to the height of the gas burner / ignition. This assumes that the driveway or other vapor paths flow downhill from the garage. and that the garage door does not make an airtight seal. If this is not the case, it is possible that a vapor pool could build up to reach even a raised heater.
      The result is that placing a gas (or even electric as thermostat contacts may spark) hot water heater in a garage or a closed space attached to a garage at garage level is generally undesirable, but, if it is unavoidable, raising the HW heater helps to reduce risk.

      The difference between the two are the 1 and 2 inches of insulation on the tank and the BTU input of 38000 (TTW1) vs 60000 (TTW2).
