Obsidian’s versatile installation options give you the flexibility to put this electric heater in nearly any outdoor location. This easy installation heater is also simple to operate; all sizes of Obsidian are controlled by a handheld remote.

Adjustable mounting brackets make Obsidian a breeze to install on walls. All it requires is a suitable mounting structure and a minimum ceiling clearance of 12 inches.
