Abstract
A combination heater-light-ventilator unit for mounting in a ceiling, is disclosed. A cylindrical housing supports the unit and an annular grille on its bottom includes an arcuate heat discharge outlet around part of its circumference and an arcuate air intake through the remainder, with a light diffuser supported in the center. The heat discharge outlet is configured to direct heat flow relatively straight down from the unit to minimize its recirculation through the arcuate air intake.
