How Do High-Efficiency Condensing Gas Tank Water Heaters Work?
State high-efficiency condensing gas tank water heaters work with the same traditional technology as standard gas water heaters-and they're just as simple to get up and running. The cold water is heated at the bottom of the tank, and hot water is pushed out through the outlet connection.
However, because of State's commitment to seeking water heater innovation, high-efficiency condensing gas tank water heaters are built with a helical internal heat exchanger rather than a straight pipe. This design allows for more heat to be transferred into the water, which reduces energy use by 29% or more compared to a standard gas tank water heater.
