Hybrid Water Heater -Tankless Crossover – TTX Series
worlds!
Giant’s TTX series offers an exceptional performance while providing an increase in hot water capacity.
These models are designed with a technology that combines a traditional water heater and a Tankless water heater.
This system allows you to recover the equivalent of two 50 gallon standard water heaters while using a 40 gallon storage tank.
The water is heated in the engine (Tankless) and not directly in the tank, resulting in less thermal stress on the inner-tank.
A temperature controller including five different settings allows you to set your desired heat level.
Installation is easy and hassle-free.

Benefits
CAPACITY TO SUPPLY - TANKLESS TECHNOLOGY
Continuous hot water simultaneously to multiple plumbing fixtures. Hot water recovery is much faster than a traditional water heater.
FACTORY INSTALLED 3/4" NPT DI-ELECTRIC NIPPLES
Extends the life of the water heater by providing excellent corrosion protection.
FLAMMABLE VAPOR SENSOR
Detects the presence of flammable vapors and shuts down the water heater.
FACTORY INSTALLED TEMPERATURE & PRESSURE-RELIEF VALVE
Protects the tank from the damaging effects of excessive temperature and pressure.
INSULATION
A thick uniform blanket of 
eco-friendly insulation keeps the water hotter for longer periods,
reduces standby losses and energy costs. contains no HCFC’S (hydrochlorofluorocarbons), CFC’S (chlorofluorocarbons) nor VOC’s (volatile organic compounds).
NO EXHAUST FLUE IN STORAGE TANK
Minimizes standby heat loss.
OPERATION UNIT & TEMPERATURE CONTROL
Allows quick adjustments for desired temperature. The diagnostic capabilities of the controller also makes it easy to operate.
QUICK AND EASY INSTALLATION
Similar to a standard water heater, makes it perfect for sameday replacement. Indoor installation only.
STANDARD WATER CONNECTIONS:
1/2" (1,3 cm) gas line supply MNPT*
4" (10 cm) diameter Type B-
3/4" MNPT Hot water outlet
Temperature and pressure-relief valve: 3/4" FNPT
3/4" MNPT Cold water inlet
COMBUSTION AIR SCREEN
Equipped with a Combustion Air CO sensor. It allows the water heater to shut down if carbon monoxide is detected in the combustion chamber.
EASY SERVICE ACCESS TO COMPONENTS
For fast repairs and part replacements.
* As with all gas appliance applications, installers should check and abide by local gas-pipe size and national federal gas codes
