Abstract: A cooktop burner assembly is described. The cooktop burner assembly includes a main burner, and a simmer burner located below the main burner, where a diameter of the simmer burner is greater than a diameter of the main burner.  The closer placement of the main burner to a cooking vessel placed on top of the cooktop burner assembly as compared to the placement of the simmer burner from the cooking vessel increases thermal efficiency. Moreover, the farther placement of the simmer burner from the cooking vessel facilitates simmering of items in the cooking vessel and the larger diameter of the simmer burner reduces a possibility of overheating the main burner and the cooking vessel.
