The DLX 80 is a low-efficiency single-speed furnace, with an energy efficiency rating of 80%. Its heat exchanger is made from aluminized steel and uses a ripple-edged design. There’s thermal lining on the cabinet to reduce noise. The system is monitored and managed by electronic controls, but it lacks many of the features available for Tempstar’s more advanced models.
The DLX 80 contains a humidifier and air cleaner for improving the quality of air as it’s being heated. Other special features include interior UV lights to kill off microbes that might otherwise grow on the coils.
