Description
–
This Bradford White water heater utilizes a draft diverter and is atmospherically vented. It is perfect for many standard water heating applications.
Features:
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.
- 2" 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.
- T&P Relief Valve - Included.
- Brass Drain Valve - Tamper proof design

Great service!
This was a replacement for My aging water heater. My handyman had no issues installing it though it was a couple inches shorter than the description.

I would not buy this unit again
Had this 40 gal 40k btu water heater installed 2-2-10, it only lasted to 11-30-18. I just replaced with a Rheem which I researched and was surprised is a much better unit.

Quality Product
Bought this water heater for my home. Replaced a 31yr old Bradford White heater that was still working, but I thought it's only time before it went bad. The new one arrived in 5 days. The box was in good shape; the water heater had a little 4" crease in the side which was no big deal. Had it installed in less than 2hrs. Would give it 5 stars but only have had it in for four days. Hope it last as long as the last one.

Great product
The unit replaced my former water heater and was almost a direct replacement. Works as expected and would buy another. It was delivered late due to a mix-up at the warehouse, but we managed.

So Far... So Good!
It installed easily and it was a quick delivery! I really like the newer ICON gas control units with the LED troubleshooting. It should make things easier to troubleshoot down the road. One thing, it would be great if they would make the anode road easier to get to when replacing, but it is what it is.

No problems so far, and expect it to be so for a long time
Replaced my 22yr old Bradford White water heater, with this model of the same brand. It fit perfectly where the old one was. It was easy to secure and connect supply/gas lines. Also, easy to start the pilot with its electronic controller. The delivery was on time, and as promised, with free delivery and additional free lift gate. I am very pleased with SupplyHouse.com service.

Not reliable
My Bradford White quit heating water after 3 months. The company won't send the part that needs to be replaced, only to the plumber who wants to charge $95.00 and hour. Turning out to be a very costly experience.
