The Combi1™ Series combination water heaters are designed to provide both potable water heating and space heating from a single heat source. The heated potable water in the tank transfers its heat through the heat exchanger to the fluid within the coil. Because of its single wall heat exchanger design, the Combi1™ provides greater space heating output when compared to a double wall heat exchanger design.

The Combi1™ TTW® FVIR Defender Safety System® Models Feature 

(50T model, only):
■ Advanced ScreenLok® Technology Flame Arrestor Design—Flame arrestor is designed to prevent ignition of flammable vapor outside of the water heater.
■ Flammable Vapor Sensor—Electronic sensor prevents burner operation if flammable vapors are detected. The sensor will also prevent operation if there is ongoing flammable vapors burning inside the combustion chamber.
■ Maintenance Free—Regular cleaning of air inlet openings or flame arrestor is not required under normal conditions.
■ Sight Window—Offers a view of the pilot and burner operation.
All Combi1™ TTW® Models Feature
■ Internal Single Wall Heat Exchanger—1 1⁄2" (38mm) O.D. glass coated (Vitraglas®) steel coil.
-- 1" (25mm) NPT Solar Collector Supply and Return Connections.
■ Low Heat Exchanger Head Loss—Up to 10 GPM (38L) flow, with less than 5ft. (1.5m) of head loss. Greatly reduces the required pump size for heat exchange.
■ Honeywell Self Diagnostic Electronic Gas Control —Intelligent gas control with spark to pilot ignition system eliminates the constant burning pilot. This results in savings of pilot gas during stand by periods (120 VAC).
-- Enhanced Performance—Proprietary algorithms provide enhanced First Hour Rating and tighter temperature differential.
-- Advanced Temperature Control System—Microprocessor constantly monitors and controls burner operation to maintain accurate water temperature levels.
-- Intelligent Diagnostics—An exclusive green LED light prompts the installer during start-up and provides ten different diagnostic codes to assist in troubleshooting.
■ Factory-Installed Hydrojet® Total Performance System—Sediment reducing device that also increases first hour rating of hot water while minimizing temperature build-up in 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°F (871°C).
■ Horizontal and Vertical Venting—With 3" (76mm) or 4" (102mm) PVC, ABS or CPVC (Maximum equivalent vent lengths on reverse side).
■ Insulation System—2" (51mm) Non-CFC foam insulation covers the sides and top of the tank, reducing heat loss. This results in less energy consumption, improved efficiencies, and jacket rigidity.
■ Pedestal Base.
■ Water Connections—3⁄4" (19mm) NPT factory-installed true dielectric fittings extend water heater life and simplify water line connections.
■ Two Protective Anode Rods.
■ T&P Relief Valve—Installed.
■ Low Restrictive Brass Drain Valve—Durable tamper proof design.
■ Thermostatic Mixing Valve (ASSE Approved)—Included.
