The present invention relates to a process of making power-saving electric stoves, particularly having a large size and outer shapes similar to the conformations of traditional Tyrolean heaters or stoves, while having a very light weight and being easily movable to multiple locations of a house. The main characteristic of the present invention is that it includes making a hollow stove body, particularly having a large size, from expanded polystyrene or a similar thermoplastic polymer, with the application of an electric resistor, particularly a constant-power, and hence low-power consuming heating cable arranged around its outer surface in one or more coil loops with the interposition of a layer of adhesive material with at least one thread formed therein for supporting the resistor, with contiguous insulating grooves, and with later application of a final coating layer, made e.g. of tire-resistant cement mortar, whose outer surface may be provided with decorative designs or finishes and ornaments made of wood or other materials, which designs and ornaments may be similar to those formed on the outer surfaces of traditional Tyrolean stoves, whereas the basement of the hollow body is preferably supported by a smooth metal plate, allowing displacement thereof to any location of the house, proximate to a power outlet.

An electrical heating device for a motor vehicle includes an at least partially electrically conductive housing having an end face in which a circumferential groove is provided. A lid, formed from sheet metal, seals the housing. An adhesive is introduced into the groove The lid has a circumferential edge which engages in the groove such that the edge of the lid is immersed circumferentially in the adhesive. The inside dimension of the groove is smaller than the wall thickness of the lid.

A heating part of this radiant heater has a plurality of heating wires. The plurality of heating wires are connected in parallel such that a plurality of parallel groups may be formed by electrodes. Further, the plurality of parallel groups are connected in series by the electrodes. The heating parts are set to reach a radiation temperature for emitting the heat radiation which makes a human to feel warmth. The heating parts have a thermal resistance in a longitudinal direction which is set, when an object contacts on the surface, a temperature of the part where the object touches falls to a suppressed temperature lower than the radiation temperature. The temperature of the heating part increases rapidly in response to electric supply. When there is a contact with an object, the temperature of the heating part decreases rapidly.

An electronic cigarette includes a shell and a mouthpiece. The external wall of the shell has an air inlet. An atomizer and a liquid-supply are in contact with each other. The air inlet, atomizer, and an aerosol passage are interconnected.

An electric fireplace (410) includes a fireplace housing (412) and a heater assembly (426) that is configured to generate heated air. The heater assembly (426) is configured to be installed substantially within the fireplace housing (412). The heater assembly (426) includes a heater body (445), a first grill cover (448) that is selectively couplable to the heater body (445), and a second grill cover (548) that is alternatively selectively couplable to the heater body (445). The first grill cover (448) has a first cover length (468), and the second grill cover (548) has a second cover length (568) that is different than the first cover length (468). The heater assembly (426) is selectively positionable within a cabinet (311) having a structural opening (311A), and a center shelf (360) that defines at least a portion of an upper side (311U) of the structural opening (311A). The heater assembly (426) is installed substantially adjacent to the center shelf (360).

A device for heating up an exhaust gas flowing in an exhaust gas line, including a heating disk having at least one electrical conductor arranged along a conductor path. Air gaps are formed between individual sections of the electrical conductor. The heating disk is connected to a disk-like support element in an electrically insulated manner by supports. The disk-like support element has at least one web, which forms a rigid holder for the supports. The disk-like support element has at least one cutout which is in alignment with at least one of the air gaps along a main throughflow direction of the device and through which the exhaust gas can flow.

An electronic cigarette includes a shell and a mouthpiece. The external wall of the shell has an air inlet. An atomizer and a liquid-supply are in contact with each other. The air inlet, atomizer, and an aerosol passage are interconnected.

A combined housing for temperature control of a space has a top face, a bottom face, a left side face, a right side face, a front face, and a rear face. A heating assembly formed in the housing has a recess centrally positioned in the front face and a radiant heating element extending laterally within the recess. A cooling assembly formed in the housing has an input aperture formed in the rear face equally spaced from the left and right side faces, a first output aperture formed in the front face between the recess and the left side face, and a right output aperture formed in the front face between the recess and the right side face.

An electrical heater assembly, fluid treatment assembly, and method of manufacturing same are disclosed. The electrical heater assembly includes a heater body including a resistive portion and a plurality of slits in the resistive portion. The slits electrically disconnect sections of the resistive portion from each other to define a serpentine current-carrying path through the resistive portion. An electrode attachment portion us connected at an end of the serpentine current-carrying path. An electrode is included that includes a first end that is electrically connected to the heater body at the electrode attachment portion. The first end extends in a transverse direction from the heater body.

A holding device for at least one heating element, in particular for a PTC heating element or a mica heating element, including at least two oppositely arranged holding elements, which are spaced apart from one another by a gap, which extends along a longitudinal direction of the holding device and is adapted for receiving at least one heating element, and including a heat transfer body with at least two chambers, which respectively form an inner region, through which a gaseous medium can flow, wherein the opposite holding elements are arranged between the two chambers and the gap connects the inner regions of the chambers.
