state WATER HEATERS GTS-240X3 Residential Gas Water Heaters

State 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.

FEATURES

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
