Broan-NuTone 1250W 120V 10.42A Wire Element Fan-Forced Ceiling Mount Heater. With 4,266 BTU's and a chrome alloy wire element, this heater provides instant heat. Its low profile housing with a satin finish aluminum grille extends only 2-3/4" from the ceiling, making it ideal for small spaces. The exclusive enclosed sheathed element ensures safety, while the built-in fan disperses heat evenly. Automatic overheat protection and a permanently lubricated motor guarantee years of reliable use. It mounts easily to any standard 3-1/2" or 4" round, or 4" octagonal ceiling electrical box.
