A convection heater, also known as a convector heater, is a type of heater that utilizes convection currents [1] to heat and circulate air. These currents move through the appliance and across its heating element, [ 2 ] using thermal conduction [ 3 ] to warm the air and decrease its density relative to colder air, causing it to rise.
A radiator is a device that transfers heat to a medium primarily through thermal radiation.In practice, the term radiator is often applied to any number of devices in which a fluid circulates through exposed pipes (often with fins or other means of increasing surface area), notwithstanding that such devices tend to transfer heat mainly by convection and might logically be called convectors.
30 kW resistance heating coils This radiant heater uses tungsten halogen lamps. Electric heating is a process in which electrical energy is converted directly to heat energy. Common applications include space heating, cooking, water heating and industrial processes. An electric heater is an electrical device that converts an electric current ...
An oil heater, also known as an oil-filled heater, oil-filled radiator, or column heater, is a common form of convection heater used in domestic heating. Although filled with oil , it is electrically heated and does not involve burning any oil fuel ; the oil is used as a heat reservoir (buffer).
This color schlieren image reveals thermal convection from a human hand (in silhouette form) to the surrounding still atmosphere.. Two types of convective heat transfer may be distinguished:
Turning off the heater when the last adult leaves the room or goes to sleep and keeping children and pets three feet away from the heater. Placing heaters on a flat, hard, nonflammable surface. Avoiding the use of heaters near flammable materials such as paint or gasoline. Installing smoke alarms and carbon monoxide detectors nearby.
Heating systems are classified into two main types; central heating and distributed heating. Central heating systems generate heat (electrically or by burning gas/coal) in a single location and distribute the heat through ducts pipes or radiators. Distributed heating systems involve localized heat sources, such as space heaters or electric ...
Outdoor radiant heaters allow specific spaces within an outdoor area to be targeted, warming only the people and objects in their path. Radiant heating systems may be gas-fired or use electric infrared heating elements. An example of the overhead radiant heaters are the patio heaters often used with outdoor serving. The top metal disc reflects ...
