Double the warmth with Infratech's WD-Series heaters. This high powered unit features dual element, to provide a more concentrated heat. This makes the WD-Series an ideal choice for recessed installation, premium outdoor heating applications, and spaces with 8' to 12' mounting heights and large-scale coverage areas. Infratech infrared heaters are 90% energy efficient, UL listed for outdoor and indoor use and are easy and inexpensive to operate. This heater is ideal for use in fine homes, restaurants, hotels and more. Similar to being warmed by the sun, infrared heaters heat surrounding objects and people, transferring the heat to surfaces and skin. Objects and people absorb the heat given off by the infrared heater, which in turn increases the warmth in the room via the people and objects that have been warmed. Because air is not heated and circulated, the differential in temperature from the ceiling to the floor varies by 2 3 degrees total. Infrared heating is an energy-efficient heating solution that is ideal for both indoor and outdoor spaces. By utilizing quartz elements our infrared heaters are able to emit a safe, clean wavelength of light that may only be absorbed by solid objects. This means the heat is transferred directly to you from your heater. Infrared heat does not blow away in breezy locations and the quartz elements are completely odorless. Features: 4,000 watt. 16.7 amps.
