The other module is used for obtaining, and transmitting to a supervision module, first and second data sets including at least one item of data relating to an electrical power source, and subsequently transmitting a first setpoint state of charge related to the state of charge of the electrical energy storage device of the other heating device. The first setpoint state of charge is taken into account when controlling the power supply to the heating member.

Devices and methods for outdoor heating. A stove device includes a fuel system attached to a combustion chamber to deliver fuel from a hopper of the fuel system to the combustion chamber for combustion in a firepot assembly positioned inside the combustion chamber. A distance between a chute of the fuel system and the firepot assembly is adjustable to change an amount of fuel for combustion and thereby control temperature of combustion. The distance may be decreased to decrease the temperature and may be increased to increase the temperature

An electric heater to heat a flow of a fluid having a jacket block comprising a plurality of longitudinal bores to allow the through-flow of a gas phase medium. An elongate heating element extends through each of the bores and is positionally stabilised relative to the jacket block via at least one support member, optionally in the form or an elongate rod to inhibit undesirable independent axial and/or lateral movement of the heating element relative to the jacket block.

The invention relates to a heating system (200) for heating of a fluid. The heating system comprises a supply connection (201) in fluid communication with a supply of fluid to be heated. It further comprises a structured body (108) arranged for heating of the fluid during use of the heating system. The structured body comprises a macroscopic structure (21) of electrically conductive material, the macroscopic structure comprising at least one channel (22) through which the fluid can flow. The heating system further comprises at least two conductors (103,114) configured to electrically connect the structured body to at least one electrical power supply. The at least two conductors are electrically connected to the structured body at a first end (204) and at a second end (205), respectively, of a conductive path within the structured body. The structured body is configured to direct an electrical current to run along the conductive path from the first end to the second end thereof. The electrical power supply is configured to heat at least part of said structured body to a temperature of below 400° C. by passing an electrical current through said structured body during use of the heating system.

A bucket heater assembly for keeping a user warm in a remote location includes a bucket that has a vent hole extending through the bucket. A chimney is integrated into the bucket and the chimney extends through the vent hole. A heat source can be positioned in the chimney for heating an interior of the bucket thereby facilitating the bucket to keep a user warm when the user is near the bucket. A lid is attachable to the bucket for closing the bucket and a pair of cushions is each of the cushions is coupled to the lid and the cushions can be sat upon by the user. A pair of shoulder straps is each coupled to the bucket for carrying the bucket. A light emitter is coupled to the lid to emit light outwardly therefrom.

Provided is a condensate water trap for a gas furnace that collects and discharges condensate water produced in a heat exchanger and an exhaust pipe. The condensate water trap includes: a first inlet through which the condensate water produced in the heat exchanger is introduced; a second inlet through which the condensate water produced in the exhaust pipe is introduced; a first flow path through which the condensate water coming from the first inlet passes; a second flow path through which the condensate water coming from the second inlet passes; an outlet through which the condensate water introduced through the first and second inlets is discharged; a third flow path into which the residual condensate water passed through at least one of the first and second flow paths but not discharged through the outlet is introduced; and a sensing mechanism that senses if the amount of residual condensate water introduced into the third flow path is greater than or equal to a given amount.

A heating device, and a method of manufacturing the device, comprises an electrically conductive heating foam, a current conducting foam and two electrodes. The heating foam is divided by interruptions into sections, providing a predefined current path extending from a current lead-in point to a current lead-out point. The electrodes are electrically connected to the current lead-in and lead-out points, respectively, wherein the heating foam is provided on an outside at least in sections with the current conducting foam forming current conducting sections that electrically connect sections of the heating foam to one another. The current lead-in or lead-out point is provided as a connection section of the current conducting foam and extends in a circumferential direction along at least one current conducting section, but is electrically insulated therefrom. The two electrodes are spaced apart from one another in the circumferential direction by less than 180 degrees.

A variable capacity furnace includes a variable capacity fuel valve configured to supply a fuel to a burner, where the variable capacity fuel valve is configured to be controlled to a target setting over a range of settings to modulate an amount or flow rate of the fuel supplied to the burner. The variable capacity furnace also includes a control assembly having processing circuitry and memory circuitry. The memory circuitry includes instructions stored thereon that, when executed by the processing circuitry, cause the processing circuitry to execute a control algorithm to determine, based on whether an indoor temperature is progressing toward a set point over time and based on a temperature differential between the set point and the indoor temperature, a target setting of the variable capacity fuel valve. The instructions also cause the processing circuitry to control the variable capacity fuel valve to the target setting.
