Bradford White's Defender System Atmospheric Vent water heaters utilize a draft diverter and are atmospherically vented with capacities ranging from 30 to 50 gallons and inputs ranging from 30,000-50,000 BTU/Hr.
These water heaters utilize a draft diverter and are atmospherically vented, however they offer Extra Recovery. This translates to an increased amount of hot water available at a usable temperature in less time than normal.
These models feature an automatic flue damper that helps to reduce stand-by heat loss. The flue damper, combined with additional insulation and heat traps, helps these units achieve one of the highest Energy Factor (EF) ratings of our atmospheric vent models.
This .70 Energy Factor (EF) water heater is atmospherically vented and utilizes a highly efficient blower to pull air through a tightly restricted baffle system. This provides a high rate of heat transfer to the water stored in the tank.
