A heating apparatus including a storage device and at least one heater member. The heater member can be connected to the storage device and an electric power supply source. An inverter is connected to the output of the storage device and the electrical supply source. First switching elements are used to vary the first connection elements between an open circuit configuration and a closed circuit configuration in which electrical energy stored in the storage device is injected into the electrical supply source via the inverter.

A combined heating and power system is configured to generate energy as well capture a large percentage of energy that would otherwise be lost using components, including heat transfer components, embedded within a vessel to transfer energy in the form of heat to liquid within the vessel.

A water heater can include a housing and a heating system disposed within the housing, where the heating system is configured to heat a fluid. The water heater can also include a switch coupled to the heating system, where the switch operates between a first position during normal operations and a second position during an outage. The water heater can further include a primary power source coupled to the switch, where the primary power source is configured to provide primary power to the heating system through the switch during the normal operations. The water heater can also include an uninterruptible power supply (UPS) coupled to the switch, where the UPS is configured to provide reserve power to the heating system through the switch during the outage, and where the UPS is integrated with the housing.

The invention relates to a device for storing temperature-controlled fluids, comprising at least one container (20), a Peltier element (30), the hot side (301) of which is in contact with at least one wall (201) of the container (209), at least one device (40) for delivering ambient air to the cold side (302) of the Peltier element (30), and at least one electrical energy source (50, 501, 502) for supplying the Peltier element (30) and the device (40) for delivering the ambient air. For low-loss storage of the fluid in the container (20), the device (40) for delivering ambient air can be operated according to the temperature of the ambient air and the heating capacity of the Peltier element (30) can be controlled according to the currently produced electrical energy of a photovoltaic solar generator (501) forming an electrical energy source. Preferably, times and/or durations of the heat energy emitted from the Peltier element (30) and/or from an accumulator (502) to the fluid can be controlled by a control appliance (6) on the basis of at least one requirements specification stored in the control appliance (60).

An operating method of a heat-storage system includes the steps of executing a first operating mode to supply heat to a first hydrogen storage alloy in a first tank, to cause movement of hydrogen from the first hydrogen storage alloy in the first tank to a second hydrogen storage alloy in a second tank, the second hydrogen storage alloy being different from the first hydrogen storage alloy in dissociation pressure characteristic with respect to an alloy temperature, and executing a second operating mode to supply cold of outside air to the first hydrogen storage alloy, to cause movement of hydrogen from the second hydrogen storage alloy in the second tank to the first hydrogen storage alloy in the first tank, in which the step of executing the first operating mode includes a step of storing a temperature generated in the second hydrogen storage alloy in a heat storage device.

A combined heat, cooling and power system is configured to generate energy as well capture a large percentage of energy that would otherwise be lost using components, including heat transfer components, embedded within a vessel to transfer energy in the form of heat to liquid within the vessel.
