Bradford White® EF-100T-250E-3N Gas Water Heater, 100 gal, 250000 Btu/hr, Natural Gas

Bradford White® Gas Water Heater, EF Series, 100 gal Capacity, 250000 Btu/hr, 970 gph Recovery Rate, 97 % Efficiency, 3 in Vent, Power Direct Vent, 15 A, 120 V, 60 Hz, NPT Connection, 150 psi, Energy Star Compliant: Yes, Natural Gas Fuel, Electronic Ignition System, On/Off Switching Action, Direct Spark Ignition, Steel, Finish: Vitraglas-Coated, 180 deg F, 77-5/8 in H x 28-1/4 in W x 28-1/4 in D, Domestic/Import: Domestic, 10000 ft Altitude

• Thermal efficiency up to 97 percent - ultra high efficiency results in less fuel consumption and greater hot water recovery
• BMS integration via modbus standard, BACnet® compatible via gateway kit
• ICON HD® intelligent proven design combines temperature control, diagnostic codes and system ignition functions into a single control board with a digital LCD display
• Protective powered anodes, each eF Series® model is provided with two powered anode rods
• Factory installed Hydrojet® sediment reduction system, cold water inlet sediment reducing device helps prevent sediment buildup in the tank
• Vitraglas® lining, 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 deg F
• Direct spark ignition for improved operational dependability and durability
• Operation mode, two different digitally displayed operation modes have the capability of adjusting the temperature setting up to 180 deg F and adjusting the degree setting ( deg F to deg C or deg C to deg F)
• Service mode, eight different digitally displayed service screens can be easily cycled through by pressing the select button
• There is the capability of adjusting the temperature setting up to 180 deg F (82 deg C), adjusting the degree setting (deg F to deg C or deg C to deg F), locking the maximum temperature setting that can be adjusted in operation mode, displaying the temperature sensor reading, displaying the flame current and displaying diagnostic codes
• Premix power burner, a self-compensating negative regulation system automatically increases or decreases fuel flow when a change in combustion air is detected
• This provides the range for optimum combustion and efficiency (automatic high altitude compatibility up to 10000 ft/3048 m)
• Venting versatility, the eF Series® can vent vertically or horizontally with either 2, 3, 4 in or 6 in (51 mm, 76 mm, 107 mm or 152 mm) PVC, CPVC, polypropylene, stainless steel or ABS (not approved for Canada) vent pipe and is approved for direct vent closed combustion applications or those applications that require inside air for combustion
• The eF Series® is also approved for unbalanced venting, which means the air intake pipe doesn't have to be vented the same distance as the exhaust
• Three pass fire tube heat exchanger system keeps the hot combustion gases moving at a high velocity, the combination of high turbulence and velocity causes an enormous rate of heat transfer into the water
• Ultra quiet operation
• A single exhaust pressure switch
• 1 in (25 mm) NPT side connections for space heating
• Temperature and pressure relief valves relief valve installed
• Low restrictive brass drain valve durable tamper-proof design
