The best way to heat a paella pan is over even heat, and given the size of paella pans, the best heat source are Paella Pan Burners. Diameter 34.5cm/13.5inch, fits pans up to 20inch or smaller. The burners consist of two concentric rings which distribute the heat evenly. Each ring has its own control value giving you greater control and the ability of using only the inner ring(s) to use with smaller pans. Gas regulator hose to connect to a standard propane tank and legs sold separately. Will last many years with proper use and care (each piece comes with a product information sheet outlining the Uses and Care for the product).
