The NuWave Oven cooks food up to 50% faster than a conventional oven through its patented 3-Way cooking method: Infrared-Conduction-Convection; INFRARED radiant heat penetrates food from the inside out leaving food moist and flavorful. CONDUCTION applies heat directly to the food enhancing browning, roasting and flavor. CONVECTION circulates heat evenly around food for faster cooking and even browning. The NuWave Oven Pro is powered by a 1,500 Watt Sheath Heater that can last up to 30 years without service. One key benefit of the NuWave Oven for todays busy consumer is the ability to cook from frozen to finished without the time consuming process of defrosting. Other key benefits are that while the NuWave Oven cooks food, it seals in a way that will not heat up the kitchen and emits no smoke or odors, thus eliminating wasted energy.
