A cooking vessel according to one example embodiment includes a food receptacle for holding food during cooking. The cooking vessel includes an inner shell and an outer shell. An outside surface of the inner shell forms the food receptacle. A portion of an inside surface of the inner shell is spaced from a portion of an inside surface of the outer shell forming a sealed volume between the inner shell and the outer shell. A heat pipe is positioned within the sealed volume between the inner shell and the outer shell for distributing heat through the sealed volume between the inner shell and the outer shell. Embodiments include those wherein each of the inner shell and the outer shell includes a respective bottom wall and a respective side wall.

Heating assemblies for cooktop appliances are provided. In one embodiment, the heating assemblies include a first portion and a second portion. The first portion includes a heat generating component and a first sheath surrounding the heat generating component. The first sheath defines a first support surface. The second portion includes a temperature sensing component and a second sheath surrounding the temperature sensing component. The second sheath defines a second support surface. The first support surface and the second support surface contact a cooking utensil when the cooking utensil is positioned on the heating assembly. The heat generating component may be configured to provide heat to the cooking utensil positioned on the heating assembly, and the temperature sensing component may be configured to sense the temperature of the cooking utensil in order to assist in regulating the temperature of the cooking utensil.

A cooktop appliance or heating coil assembly may include a heating element, a shroud cover, a thermostat, and a spring bracket. The shroud cover may be disposed within the heating element. The shroud cover may include a top wall defining an upper surface and a lower surface. The thermostat may extend vertically between a distal end and an interior end below the distal end. The distal end may be disposed against the shroud cover at the lower surface. The thermostat may be connected in series between the first and second coil sections of the spiral wound sheathed heating element. The spring bracket may be disposed against the shroud cover at the lower surface and bias the shroud cover upward.

A method for creating an electric heating source, including a body equipped with one or more housings containing mineral-insulated heating cables. The housings communicate with one or more reservoirs which accept a purely metallic solder material in solid, powder or sheet form. The device is heated in a vacuum degassing plateau, followed by a casting plateau during which the solder melts and fills the housing around the heating cables, resulting in full metal contact between the cables and the body, providing a more uniform temperature and a shorter response time to heating or cooling. Also, a heating source obtained in this manner, including an infrared faired source or an immersion heater for the heating of a liquid bath of molten metal.

An electric resistance heating coil assembly, as provided herein, may include a spiral would sheathed heating element, a thermostat, and a shroud cover. The spiral wound sheathed heating element may have a first coil section and a second coil section. The thermostat may be connected in series between the first and second coil sections of the spiral wound sheathed heating element. The thermostat may include a base and a top cap. The base may extend axially between a first end and a second end. The top cap may be held on the base at the first end. The shroud cover may be mounted to the thermostat below the top cap.
