Gas Combination Water Heaters

Bradford Gas Combination Water Heaters Type 1: With Dedicated Heat Exchanger
DEFENDER SAFETY SYSTEM® COMBI2™ AND NON-DEFENDER MODELS The Combi2™ is the ultimate system for perfect home comfort and potable water from a single energy-saving source. The secret lies in the patented 1½" O.D. glass coated (Vitraglas®)steel coil heat exchanger. First, the Combi2™ heats the potable water in the tank. Then, the heat from the hot water is efficiently transferred through the heat exchanger to the heating fluid within the coil. 75-gallon model does not include the Defender Safety System®.
	Defender Safety System Features Advanced ScreenLok® Technology Flame Arrestor design Resettable thermal switch Piezo ingiter Maintenance free Pedestal base Site Window Standard Energy Saver Features Heat exchanger - 1½" O.D. glass coated (Vitraglas®)steel coil Low heat exchanger head loss - Up to 10 GPM flow, with less than 5 ft. of head loss Factory installed Hydrojet® Total Performance System Vitraglas® lining Factory installed dielectric waterway fittings Two protective aluminum anode rods T&P relief valve installed Thermostatic mixing valve Brass drain valve 2" Non-CFC foam insulation 10-year limited warranty on tank and heat exchanger
COMBI2™ TTW® MODELS The Combi2™ TTW® offers the same dual performance aspects as the original Combi2™ atmospheric vent but with one notably difference. This product is power vented which allows combustion gases to be expelled through the nearest outside wall or through the roof. 75-gallon model does not include the Defender Safety System®.
	Defender Safety System features Advanced ScreenLok® Technology Flame Arrestor Design Flammable Vapor Sensor Maintenance Free Pedestal Base Standard Energy Saver Features Heat exchanger - 1½" O.D. glass coated (Vitraglas®)steel coil Low heat exchanger head loss-Up to 10 GPM flow, with less than 5 ft. of head loss. Vitraglas® lining Factory installed dielectric waterway fittings Thermostatic mixing valve Power Vented for positive exhaust during main burner operation Two protective aluminum anode rods Electronic gas control valve with LED display Spark to pilot ignition system T&P relief valve installed Brass drain valve 2" Non-CFC foam insulation 10-year limited warranty on tank and heat exchanger
Type 2: With Side Connections for Combination Heating Applications DEFENDER SAFETY SYSTEM® ENERGY SAVER (XR) MODELS AND NON-DEFENDER MODELS These conventional (atmospheric) vent water heaters offer side connections for space heating and “Extra Recovery” (XR) that translates to an increased amount hot water available for heating or potable use. 65 and 75 gallon models do not include Defender Safety System®
	Defender Safety System features Advanced ScreenLok® Technology Flame Arrestor Design Resettable Thermal Switch Piezo Ingiter Maintenance Free Pedestal Base Sight Window Standard Energy Saver Features Factory Installed Hydrojet® Total Performance System Vitraglas® Lining Factory installed dielectric waterway fittings Fully automatic controls Flue Baffle Protective magnesium anode rod Side tappings Snap-lock draft diverter T & P Relief Valve included Brass drain valve 2" Non-CFC foam insulation (1" on M1 models)
DEFENDER SAFETY SYSTEM® TTW2® MODELS Similar to our TTW®1 models, the TTW®2 offers higher BTU inputs, two inches of insulation and an 80% recovery efficiency. Just like the TTW®1, the TTW®2 offers extremely flexible venting options.
	Defender Safety System features Advanced ScreenLok® Technology Flame Arrestor Design Flammable Vapor Sensor Maintenance Free Pedestal Base Powerful Blower Motor Sight Window Spark to Pilot Ignition System Electronic Gas Control Valve Stainless Steel Flue Baffle Standard Energy Saver Features Factory Installed Hydrojet® Total Performance System Vitraglas® Lining Factory Installed dielectric waterway fittings Fully automatic controls Flue baffle Protective magnesium anode rod Side tappings Snap-lock draft diverter T&P Relief Valve Included Brass drain valve 2" Non-CFC foam insulation (1" on M1 models)
DEFENDER SAFETY SYSTEM® HIGH-INPUT DIRECT VENT ENERGY SAVER MODELS Our second-generation Direct Vent water heaters offer higher inputs and gallon capacities. Our same co-axial venting will go up to eight feet vertically and horizontally.
	Fully automatic controls Factory installed dielectric waterway fittings Co-axial rotational venting Side tappings for space heating Optional vent kit allows up to 8' horizontal or vertical venting extensions Factory Installed Hydrojet® Total Performance System Vitraglas® lining No electrical power necessary Protective magnesium anode rod Piezo igniter T&P valve Included Brass drain valve 1" Non-CFC foam insulation Reinforced Seals Closed Combustion
DEFENDER SAFETY SYSTEM® POWER DIRECT VENT MODELS Power Direct Vent models offer a flexible independent venting system. It too takes combustion air from the outside but incorporates a power-blower to expel combustion gases.
	Factory Installed Hydrojet® Total Performance System Vitraglas® lining Factory installed dielectric waterway fittings Side connections for space heating T&P valve included Brass drain valve 6 year limited tank warranty 2" Non-CFC foam insulation, 1" on PDX-2-65T Optional Concentric Vent Kit Termination Vertical or Horizontal Venting Flammable Vapor Sensor Electronic Gas Control Closed Combustion
