The rewards of efficiency.
At 80% AFUE††, you can depend on substantial energy savings, especially thanks to the unique RPJ® III heat exchanger. The weld-free construction, the aluminized steel material, and the integrated ripple-edged design together increase efficiency and save energy. At lower speeds, the variable-speed motor also uses less electricity.
†† AFUE stands for Annual Fuel Utilization Efficiency.
