A heating device comprises an inner tank, an outer shell, and a heater. The inner tank is received in the outer shell. An inner tank opening and an inner tank inlet are each in communication with an inner tank chamber. An outer shell opening corresponds in position to the inner tank opening. An outer shell inlet and the outer shell opening are each in communication with an outer shell chamber. An outer shell through-hole corresponds in position to an inner tank outlet. One end of an electrical heating tube of the heater is disposed at a fixing portion and electrically connected to a control circuit. The other end of the electrical heating tube is received in the inner tank chamber. The control circuit includes an electric wire for communicating with the outside. A guide channel is formed between the inner tank and the outer shell.

A fluid system of an internal combustion engine is provided with a heating device in a heating chamber. An electric heating element of the heating device is arranged between two holding bodies such that the heating element electrically and thermally contacts a contact section of at least one of the holding bodies. The heating chamber has an inner volume region between the holding bodies and at least one outer volume region arranged on an outer side of the holding bodies. The inner and outer volume regions allow fluid to flow through. The inner volume region has an enlarged section with a first spacing measured between the holding bodies. The holding bodies have a second spacing measured in a region of the contact section. The first spacing is greater than the second spacing at least at a circumferential side of the contact section facing the enlarged section.

A recirculating bath includes a reservoir for receiving a working liquid, a recirculating pump, and at least one thermal element. The recirculating pump and thermal element are located externally to the reservoir so that the reservoir has an unobstructed working space. The thermal element may be thermally coupled to the working liquid through an interior surface of the reservoir, or the working liquid may be circulated over the thermal element by the recirculating pump in a chamber external to the reservoir. The recirculating bath may also include a lid that provides access to the reservoir by pivoting on a latching hinge. When open, the lid may provide a working surface adjacent to the reservoir. The lid may also include a selector that unlatches the hinge so that the lid can be removed. The recirculating pump may be fluidically coupled to the reservoir via a manifold.

A heater system includes a heater bundle and a power supply device. The heater bundle includes a plurality of heater assemblies and a plurality of power conductors. The heater assembly includes a plurality of heater units, each heater unit defining at least one independently controlled heating zone. The power conductors are electrically connected to each of the independently controlled heating zones in each of the heater units. The power supply device is configured to modulate power to each of the independently controlled heater zones of the heater units through the power conductors.

A tankless water heater, comprising: a flow channel with a cold-water inlet pipe, a heating unit with an heating element configured to heat water flowing through the heating unit and a hot-water outlet pipe, and a control unit configured to control the tankless water heater, wherein the control unit is configured to receive a power limitation signal of an external facility management system and to control a heating output of the heating element depending on the power limitation signal.

The present invention relates to a heating system component, including a carrier unit having a dry side, a wet side, a groove provided on the dry side, and a medium leading section at least partially opposite a medium flow area on the wet side; a heating unit at least partially received in the groove; a heat conducting plate assembly that comprises a first heat capturing plate portion that is thermally coupled to the heating unit, a second heat capturing plate portion that is thermally coupled to the medium leading section of the carrier unit, a first heat releasing plate portion, and a second heat releasing plate portion; at least one printed circuit board comprising circuitry with a first sensor area and a second sensor area, wherein the circuitry is configured to sense a first temperature at the first sensor area and a second temperature at the second sensor area; a housing accommodating at least a part of the printed circuit board and at least a part of the heat conducting plate assembly in such a way that the first sensor area is thermally coupled to the first heat releasing plate portion and the second sensor area is thermally coupled to the second heat releasing plate portion.

A solar powered water heating assembly for supplying hot water from an exterior faucet or pipe includes a heating unit and a solar panel. The heating unit is integral to, or can be engaged to, a pipe that is in fluidic communication with water piping of a structure. The pipe extends externally from the structure. The heating unit is positioned to heat water flowing through the pipe. The solar panel converts electromagnetic radiation into an electrical current. The solar panel is operationally engaged to the heating unit and thus is positioned to power the heating unit to heat the water flowing through the pipe.

A flow sensor of a domestic appliance has an axle that is substantially perpendicular in the installed state to the flow direction of a fluid channel of the domestic appliance. The bearing component is designed as a single part and has at least two interconnected limbs, each limb having an axle mount for one end of the axle of the flow sensor, wherein the two axle mounts are mutually spaced apart in such a way that they correspond in a relaxed condition of the bearing component to an extension of the axle of the flow sensor. The two limbs are designed to be elastic such that the spacing between the axle mounts can be increased in order to insert the flow sensor between the axle mounts.
