A.O. Smith Effex®

The highest efficiency standard gas model, ideal for replacement applications.
- Effex® High Efficiency Gas AOSRG46900
- GAHH-40
- GAHH-50
How does the Effex® work?
The high efficiency performance of the Effex model is possible thanks to its patented air intake system. Air is pushed into the combustion chamber creating a pressurized environment. Due to this “turbo charge” effect, tighter baffling is incorporated in the flue design to slow down the hot gas as it travels through the water heater. This results in more heat transferred to the water and less energy wasted.
