Sunpak® heaters are simple to operate and use draft free and highly energy efficient infrared radiant energy just like the sun's warming rays. These professionally mounted heaters come with either a single stage output, which can be controlled with a standard wall on/off switch or two stage output controlled with a wireless handheld remote or "ON-OFF-HI-LOW" wireless wall control or hardwired with a duplex switch. *** Installation by a Licensed Contractor Required.
