An electric heating device includes a housing having a partition wall which separates a connection chamber from a heating chamber for dissipating heat and from which at least one receiving pocket protrudes into the heating chamber as a heating rib. A PTC heating device with at least one PTC element and conductor tracks for energizing the PTC element with different polarities, which are electrically conductively connected to the latter and which are electrically connected in the connection chamber, are received in the housing. The PTC element and at least one of the conductor tracks are received in a heater casing. The heater casing is pressed into the receiving pocket subject to plastic deformation of the heater casing and/or the receiving pocket.

Disclosed is a method for producing an electrical heating device with an electrical heating element, which is arranged in the interior of a multi-part tubular metal jacket embedded in an electrically insulating material, wherein the electrical heating device has, within the multi-part tubular metal jacket, on at least one end, an unheated area, in which, during operation of the electrical heating device, electrical current flows at least also through at least one connection wire, and/or at least one connection sleeve and/or at least one connection pin, which is in electrical contact with the electrical heating element, and further has a heated area, in which, during operation of the electrical heating device, electrical current flows only through a section of the electrical heating element running in the heated area. An electrical heating device with a multi-part tubular metal jacket, which can be produced with this method, is also disclosed.

A household appliance includes a treating chamber and a liquid sump. A liquid circuit fluidly couples the liquid sump and the treating chamber. An immersible laminate heater is located within the liquid sump. The immersible laminate heater includes a pair of electrodes and a structure including at least a first layer and a second layer.

A system for the production of molten salt. The system can have a preparation tank configured to melt raw salts, and a bubbler system in communication with the preparation tank. The bubbler can be configured to maintain vacuum conditions within the preparation tank and to remove gases from the preparation tank. A method for producing molten salt includes a step of providing a system for the production of molten salt. The system can have a preparation tank configured to melt raw salts, and a bubbler system in communication with the preparation tank. The bubbler can be configured to maintain vacuum conditions within the preparation tank and to remove gases from the preparation tank. Then, the method can include inserting raw salt into the preparation tank, and heating the raw salt to form molten salt. Then filtering the molten salt, and storing the molten salt.

A multi-segment, heated hose has temperature sensors at or near the outlet of each hose segment. Each hose segment also has separate means for heating a fluid in the hose segment. A heater power controller receives temperature data from each temperature sensor and independently adjusts the power to the heater in each hose segment to obtain and maintain a preselected fluid temperature at the outlet of each hose segment.
