An Elegantly Designed Heat Source Without The Harsh Lights. Overhead patio heaters often do the job of providing warmth and comfort but there’s always this one caveat. Most heaters produce bright orange glows that are straining to the eyes. RADtec Design Series offers maximum comfort with its zero-light panels. Experience the warmth of infrared heat without compromising the comfort of your eyes. Stay toasty with its 2400W that can heat an 80 sq. ft. indoor space or a 50 sq. ft. covered outdoor patio. Experience efficient heating as its infrared heat warms people and objects and not the air in between. Sit back and relax while you navigate through its four power levels and set the timer for 2, 4, or 8 hours with the included handheld remote for the standard model or with your phone for the Wifi Smart Controlled model. Install this heater anywhere in your home as it is designed for both indoor and covered outdoor use. With a water resistance rating of IP54 and a carbon fiber heating element, you can enjoy its function for several years with zero maintenance. Constructed with anodized aluminum casing, the Design Series also got the aesthetics covered.
