A fan assembly includes a motor-driven impeller for creating an air flow, a casing including an interior passage for receiving the air flow, and a plurality of air outlets for emitting the air flow from the casing. The casing defines and extends about an opening through which air from outside the casing is drawn by the air flow emitted from the air outlets. The fan assembly also includes at least one heater for heating at least a first portion of the air flow, and means for diverting at least a second portion of the air flow away from said at least one heater. The plurality of outlets includes at least one first air outlet for emitting the relatively hot first portion of the air flow and at least one second air outlet for emitting the relatively cold second portion of the air flow.

Systems and methods for providing a personal heater are disclosed. In some embodiments, the personal heater comprises a housing, a heating element, and a controller. The housing is configured with an opening for receiving one or more feet. The controller is configured to cause the heating element to heat one or both of an interior and an exterior of the housing based on whether the one or more feet are inside the housing.

Disclosed is a heater including a housing assembly and a heating assembly. The housing assembly includes installation housings nested with each other in sequence, to make the housing assembly retractable, when the housing assembly is extended, interiors of the plurality of housing assemblies communicate with each other to form a heat dissipation channel, the installation housing located at a bottom of the housing assembly is provided with an air inlet, and the installation housing located at a top of the housing assembly is provided with a heat dissipation port; and the heating assembly provided inside the heat dissipation channel.

A portable forced air heater including a housing, a heating element located within the housing, a sensor configured to sense a characteristic of the portable heater, a communications device configured to communicate with an external device, and a controller having an electrical processor and memory. The controller is configured to receive, from the sensor, the characteristic of the portable heater, and output, via the communications device, a signal indicative of the characteristic of the portable heater to the external device.

A heat generation systems for use with an electrical apparatus is provided. The invention includes; a positive temperature coefficient (PTC) heating element, an air generator and a control structure. The control of the air generator and the heating element by the control structure provides a more precise, graduated and controllable heat output from the device.

A heater includes a housing extending longitudinally between a rear intake end and a front discharge end, a support attached to a lower portion of the housing, and a cylindrical combustion chamber secured within the housing. A control unit is disposed within the support adjacent to the combustion chamber. A heater control panel is disposed on the support and electrically connected to the control unit, the heater control panel including an ignition switch for selective operation of the control unit to power an igniter. An electrical conductor is electrically connected to the control unit, wherein the support is configured to retain a battery for connection with the electrical conductor, to power the control unit. A plug is connected to the support and electrically connected to the control unit by a rectifier to convert AC power from an external power source to DC power to supply to the control unit.

A liquid fuel portable heater (100) comprises: a combustion chamber (101) having a fuel inlet with a nebuliser (13); an electric pump (10) having an inlet (11) for suctioning said liquid fuel from a tank (6), and an outlet (12) connected to said nebuliser (13); a control unit (20) configured so that, when the heater (100) is turned on, said control unit (20) supplies the electric pump with a sequence of pulses (115, 115) with a non-zero voltage, and pause intervals (116) with a substantially zero voltage alternating with said pulses, wherein the average duration of the pulses (115, 115) is less than the average duration of the pause intervals (116). In addition, a method for controlling an electric power supply of a fuel electric pump (10) of a liquid fuel portable heater by means of an electric control unit (20) configured to control said electric power supply, comprising a step of electrically supplying said pump, once the heater is turned on, with a sequence of pulses (115, 115) with a non-zero voltage, and pause intervals (116) with a substantially zero voltage alternating with said pulses, wherein the average duration of the pulses (115, 115) is less than the average duration of the pause intervals (116).
