Ron Jaworski -- ESPN analyst and former All-Pro NFL quarterback -- is a proud member of Bradford White's winning team.

Bradford White is proud to introduce its Defender Safety System® a new combustion technology that resists the ignition of flammable vapors that can occur outside of the water heater.

The Bradford White Defender Safety System® was introduced on July 1, 2003 to meet the new American National Standards Institute's (ANSI) standard for residential gas water heaters.

The Bradford White Defender Safety System® maintains outstanding efficiency, a long service life and very low NOx emissions.

Best of all, it provides maintenance free operation while meeting the stringent ANSI standard for residential gas water heaters.
