NOTE: Due to recent changes on its design, the new Allegro II is no longer compatible with the programmers. Only units with a manufacturing date of 41/18 (week # 41-2018) or previous are compatible with the Programmer.

The Convectair Allegro uses natural convection to transfer heat into the air creating a silent, gentle flow at a stable and consistent temperature. It provides consistent, even-flowing heat to any room and requires less energy to function than a fan-forced heater. Unlike typical fan-forced heaters, the Allegro II 18’s use will be felt but not heard. The Allegro II 18 is programmable, which allows it to adjust the temperature when the room is unoccupied based your chosen settings. With its cast aluminum heating element, the Allegro II 18 pulls in cool heat from below and reheats it, distributing it evenly throughout any space. This model is the middle-range natural convection heater in the Allegro II line.
