Space heaters also have a hidden hazard: They can cause overheating — aka hyperthermia — especially in kids, people with disabilities and older adults who may have difficulty leaving a room ...
The rate of heat flow is the amount of heat that is transferred per unit of time in some material, usually measured in watts (joules per second). Heat is the flow of thermal energy driven by thermal non-equilibrium, so the term 'heat flow' is a redundancy (i.e. a pleonasm). Heat must not be confused with stored thermal energy, and moving a hot ...
Here, as common experience demonstrates, when a hot body T 1, such as a furnace, is put into physical contact, such as being connected via a body of fluid (working body), with a cold body T 2, such as a stream of cold water, energy will invariably flow from hot to cold in the form of heat Q, and given time the system will reach equilibrium.
Convective space heaters utilize convection to transfer heat from the power source to a space. These heaters typically either rely on natural or forced convection. Natural convection is a phenomenon where temperature variations in an environment generate fluid flow.

If the space heater's plug or cord, the wall outlet or faceplate is hot, stop using the heater. Call an electrician to check the plug or faulty wall outlet, or a repair person if the cord is hot.
In general, the study of heat conduction is based on several principles. Heat flow is a form of energy flow, and as such it is meaningful to speak of the time rate of flow of heat into a region of space. The time rate of heat flow into a region V is given by a time-dependent quantity q t (V).
Thousands Vornado space heaters sold online have been recalled, according to the U.S. Consumer Product Safety Commission, thanks to possible risk for electric shock and fire.
