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.
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 cast iron convector radiator from 1904. Heat transfer from a radiator occurs by two mechanisms: thermal radiation and convection into flowing air or liquid. Conduction is not normally a major source of heat transfer in radiators. A radiator may even transfer heat by phase change, for example, drying a pair of socks. In practice, the term ...
Convection (or convective heat transfer) is the transfer of heat from one place to another due to the movement of fluid. Although often discussed as a distinct method ...
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).
Radiant heating and cooling is a category of HVAC technologies that exchange heat by both convection and radiation with the environments they are designed to heat or cool. There are many subcategories of radiant heating and cooling, including: "radiant ceiling panels", [ 1 ] "embedded surface systems", [ 1 ] "thermally active building systems ...
