XE GAS TANKLESS WITH X3

SCALE PREVENTION TECHNOLOGY

Takagi has combined water heating and treatment in a product designed to

revolutionize tankless water heating. Our new condensing gas tankless line

features X3 Technology that extends life on the unit up to three times longer than

traditional/unprotected models.

X3 SCALE PREVENTION

TECHNOLOGY (PATENT PENDING)

• No annual descaling required

• No scale buildup means the heater maintains

like-new performance longer

ENERGY STAR

QUALIFIED

DURABLE HEAT EXCHANGER

• Primary heat exchanger is constructed of a

commercial-grade copper that is more resilient

to corrosion. Copper is 25x better at heat

transfer than Stainless Steel, thus stabilizing

outgoing water temperatures quicker

• Secondary heat exchanger is made of 316L

Stainless Steel to protect against corrosion

QUALIFIED AS LEAD FREE UNDER

THE SAFE DRINKING WATER ACT

SAFETY FEATURES

• Exhaust & Water Temperature Safety Control

• Overheat Cut-Off Fuse

• Air-Fuel Ratio (AFR) Sensor

INTERNAL FREEZE PROTECTION

SYSTEM

RECIRC CAPABLE

• Tankless water heaters with X3 Technology are

approved to work with an external recirculation

pump and cross-over valve. See training

manual for full details.

POWER DIRECT VENT DESIGN

• Category III or IV venting can be used

• Exhaust, 3” PVC up to 70’; 4” PVC up to

100’

• Provides ﬂexible venting with PVC, CPVC,

polypropylene, or ABS Pipe for Intake and

Exhaust (solid core only)
