An offset mounting bracket that comprises a primary member and a stabilization member can be used to mount multiple heat engines to a water storage tank. An offset mounting bracket can include a primary member, having a top surface, a bottom surface, an inner surface, and an outer surface. The offset mounting bracket can also have a stabilization member, having a top surface and a bottom surface, a supporting surface that is opposed and connected to the primary member outer surface. The offset mounting bracket can also have a connecting member. The connecting member can be configured to fasten to the top of a water storage tank. There, the offset mounting bracket, can provide a surface to mount a heat engine that otherwise would not fit onto the water storage tank structure.

A smart electric heating device comprises a storage unit, a first heating unit, a second heating unit, a control unit and a first temperature sensing unit. With the first temperature sensing unit to obtain an ambient temperature, the control unit compares the ambient temperature with a maximum increased temperature and a set temperature for controlling the first heating unit and the second heating unit to actuate. In this way, each user can use hot water of sufficient temperature better.

A water heater system includes a water heater and a thermal mixing valve. The water heater includes a tank and a cap that each define interior volumes. The interior volume of the tank includes a heating element is the location where fluid is heated, whereas the cap includes a volume within which the thermal mixing valve may be disposed. The thermal mixing valve pulls cool and warm water from the volume of the tank, and then discharges a mixed stream of fluid at a user desired temperature via an outlet.

An electric heater (1), in particular for heating, in particular thawing, an aqueous solution comprising urea inside a tank (100) to save fuel and abate pollution of a motor vehicle, the electric heater (1) comprising—a thermally conductive body (20), provided with a wall (23) which at least partially extends about an axis (Z), comprising two opposite faces (21, 22); a plurality of fins (24, 25) which extend transversally from at least a first face (21) of said two faces (21, 22); at least one heating element (40), adapted to be connected to a source of electricity to generate heat, comprising a stretch (41) arranged inside the wall (23), which extends along the wall (23), whereby the heat generated by the at least one heating element (40) can be transmitted to the body (20) and to the substance to be heated.

A liquid heater may heat liquid using at least one of an electric heater or a hybrid heat pump. The liquid heater includes a tank to store liquid, an insulator at an outer surface of the tank, and a case surrounding the insulator. The case includes a first outer panel, a second outer panel, and a cover panel fastened between the first outer panel and the second outer panel. The cover panel is detachable from the liquid heater to access electronic devices such as a controller for the electric heater.

A storage type electric water heater provides hot water and hot air. A large amount of hot water can be instantaneously tapped by a hot water generating means, and hot air can be generated by a hot air generating means.

A liquid heating system includes an instantaneous heater (18) having an inlet (20) connected to a reservoir (62). The outlet (22) of the heater is connected to fixtures (72) which use the heated liquid, and is also connected through a return connection (30) to the reservoir. In an idle mode, a pump 40 draws liquid from the reservoir (62), so that the liquid circulates through the heater and back to the reservoir. A controller (52) actuates the heater to heat the liquid to a first setpoint temperature, so that the liquid in the reservoir stabilizes at the first setpoint temperature. In a supply mode, some or all of the heated liquid flows from the outlet to the fixtures (72). Cold liquid is admitted from a supply (60) to the reservoir, and cold liquid desirably also is supplied to the heater inlet along with liquid from the reservoir, so that the heater inlet receives a combination of these. The controller controls the proportion of cold liquid to liquid from the reservoir in the combination, so as to maintain the heater at a setpoint heating rate while also maintaining the temperature of liquid discharged from the heater outlet at or near a setpoint temperature.

A heating device, including at least one heating unit, which is configured to heat at least one fluid; at least one fluid supply line, which is provided for supplying the fluid to the heating unit for heating; at least one fluid discharge line, which is provided for discharging the fluid from the heating unit after the heating; and a control and/or regulating unit, which is configured to operate the heating unit in a pulsed manner, in at least one operating state, in order to set a particular temperature. The heating device includes a valve unit, which is configured to mix the fluid in the fluid discharge line with fluid from the fluid supply line, upstream from an outlet.

A hot water supply system decouples an intelligent hot water storage system from a water heating engine system. The water heating engine system includes a plurality of instantaneous water heaters that provide for redundant operation for improved reliability. The intelligent hot water storage system includes a storage tank that encloses a volume for storage of water. The intelligent hot water storage system includes a recirculation loop driven by an integrated pump and operated by an integrated controller. By positioning the tank recirculation outlet and inlet farther apart from each other, additional usable volume of hot water is provided by the intelligent hot water storage system. Isolation valves positioned on the input and output of a recirculation pump in the recirculation loop facilitate repair or replacement of the recirculation pump. The hot water system provides for increased capacity while providing redundant heating engines in a smaller floor space than conventional systems.

A water dispensing apparatus includes: a filter; a hot water tank; a water discharge nozzle; a hot water pipe connecting the hot water tank to the water discharge nozzle; a hot water discharge valve; a drain pipe branched from the hot water pipe; a drain valve disposed at the drain pipe; a first temperature sensor disposed in the hot water tank and configured to detect a first temperature of the hot water tank or water in the hot water tank; a second temperature sensor disposed in the hot water discharge valve and configured to detect a second temperature of water that is in the hot water pipe or introduced into the hot water discharge valve; and a controller configured to control the hot water discharge valve and the drain valve based on temperature information including the first temperature and the second temperature.
