The TRUE Induction TI-4B 30 inch 4 burner electric induction cooktop is an energy efficient top that offers the perfect union of a sleek design and advanced technology. True induction cooktop with quick response times, even heat and instant heat adjustments, the True Induction is a state of the art cooktop at a better value than the competition. 30 inch induction cooktop, the high quality and affordable price is what made True Induction the brand used by Winnebago RV's and other RV manufacturers. Induction cooking utilizes a system that generates heat by a magnetic circuit that connects with ferrous metal (steel/cast iron) cookware and allows the heat to be generated by the cookware being used. This process is extremely energy efficient because the cooktop itself does not produce any of the heat used when cooking. This heating method allows your pots and pans to heat to the correct temperature in about 45 seconds, and also allows water to boil in about 90 seconds. Optimal cookware has a flat bottom and a diameter of 4.5" - 12 inches. The quick test for induction compatibility: A magnet should be able to stick to the bottom of the pan. Some of the key features that separate the True Induction TI-4B 30 inch cooktop from the competition include True Inductions EZ touch controls, a simple user interface, a durable Japanese NEG beveled ceramic glass cooktop as well as many safety features. The EZ touch controls are one of the main features that separates True Induction's 30 inches 4 burner cooktop from the competition. Most cooktops require users to learn a master set of controls to manage each burner, whereas True Inductions EZ Touch controls are intuitive as each set of controls is for a specific burner.
