Presented is a heating element, and method for producing same, comprised of strip material having a length, width and depth where the strip material is twisted at least once axially relative to its length and bent at least once across its width resulting in a generally flat profile. The twists and bends provide for expansion and contraction of the heating element and thereby provide stress relief during heating and cooling.

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.

The present invention provides an infrared sauna room with a low electric field and low electromagnetic wave radiation comprising a room body, heating plates with a low electric field and low electromagnetic wave radiation and shielding lines, wherein a plurality of heating plates with a low electric field and low electromagnetic wave radiation are distributed in the room body; the first insulating layer has concave points or/and convex points; and the shielding line comprises a stranded power wire, an electric field absorbing shielding layer and a wire insulating layer. Through the above-mentioned manner, the infrared sauna room with a low electric field and low electromagnetic wave radiation can significantly reduce electromagnetic wave radiation and electric field radiation for sauna rooms.

A fluid pipe device is provided, which includes a pipe member forming a flow channel for flowing a fluid; a heating member for generating heat to heat the pipe member; a metal heat transfer member abutting against the heating member and conducting the heat to the pipe member; and a terminal member electrically connecting the heating member and the heat transfer member. The heat transfer member includes a first heat transfer member and a second heat transfer member, and at least one of the first heat transfer member and the second heat transfer member forms the terminal member at one portion, and the first heat transfer member is provided in the pipe member in such a way as not to be exposed inside the flow channel of the pipe member.

A wax warmer assembly includes a housing having an outermost edge defining an opening and an annular ridge below the outermost edge. The wax warmer assembly further includes a dish with a peripheral edge, a heater affixed to the dish, and a power cord in electrical communication with the heater. The heater is operable to only draw 10 Watts of power or less from a power source. Further, the dish is disposed in the opening of the housing and the peripheral edge of the dish engages with the annular ridge of the housing.
