Efficiency savings
At 92.1% AFUE††, This unit takes fuel efficiency to the highest level. The patented RPJ® III heat exchanger is the key. Made of weld-free stainless steel for exceptional durability, the integrated ripple-edged design forces more heat to the outside surface area to increase efficiency and save energy. At lower speeds, the variable-speed motor also adds savings on eletrical power.
†† AFUE stands for Annual Fuel Utilization Efficiency.
