eF SERIES® ULTRA HIGH EFFIENCY WATER HEATERS
Now the eF Series® is even better with the addition of an Honeywell® Integrated Control System! This intelligent, proven design combines temperature control, diagnostic codes, and system ignition functions into a single control board with a digital LCD display. The control system features two different modes (operation and service) that prompt the installer during start-up and provide 10 different diagnostic codes to assist in trouble shooting. These models offer remarkable thermal efficiency ratings as high as 99.1% – an unprecedented rating that makes this line of water heaters the most efficient in its class. In addition to this remarkable performance, the eF Series® is secondto-none in installation flexibility. All models are capable of Power Venting (using inside air for combustion) or Power Direct Venting (using outside air for combustion) and can vent vertically or horizontally. They are also approved for unbalanced, direct-vent closed combustion applications. Unbalanced venting means the air intake pipe doesn’t have to be vented the same length, or on the same external building surface as the exhaust vent (a feature not available on competitors’ models). The eF Series® is also noticeably quieter, and homeowners, building owners and managers and occupants will appreciate the difference.
The eF Series® gives home and building owners, engineers and plumbing and heating professionals:
Reliable, Trouble-Free Performance
Thermal Efficiency Ratings Up To 99.1%
High First Hour Delivery Ratings (up to 521 gallons)
Power Vent or Power Direct Vent Capabilities
An Optional 3" Concentric Vent Kit Termination
An Optional “Energy Savings” Programmable Setback Control

The eF Series® is one of the most exceptional additions to Bradford White’s residential and commercial line-up. Utilizing exclusive designs and technologies, the eF Series outperforms the competition when it comes to installation flexibility, quiet operation and, most importantly, efficiency.

Bradford White Commercial Ultra High Efficiency Models are:
Stainless Steel Baffles Venting: up to 120 Equivalent Feet with 3" PVC, CPVC or ABS Vent Pipe
Venting: up to 170 Equivalent Feet with 4" PVC, CPVC or ABS Vent Pipe
Exhaust Elbow with Built In Condensate Trap
Combustion gases generated by the Premix Power Burner travel through three heat exchangers. The combustion gases enter the 1st pass heat exchanger at a temperature above 2000°F. The gases then travel down the 8" flue tube, efficiently transferring heat to the surrounding water, and reach the 1st pass collector at a temperature near 1100°F. Gases are then redirected upwards into two 4" 2nd pass heat exchangers and end up in the 2nd pass collector. The gases, which have now been reduced to 500°F, are forced downward through eight 2" 3rd pass heat exchangers and reach the exhaust collector at a temperature of 120°F. This reduced temperature is below the allowable core temperature for plastic pipe, which allows the use of PVC, CPVC or ABS vent pipe (Canada must use specific uLC S636 vent material).
A 199,999 BTU/hr. eF model, compared to a standard 199,999 BTU/hr. 80% efficient model, will save approximately $1,338.15 a year (based on 8 hrs of operation per day and $1.22/therm).
