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).
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.
Constant air volume (CAV) is a type of heating, ventilating, and air-conditioning system. In a simple CAV system, the supply air flow rate is constant, but the supply air temperature is varied to meet the thermal loads of a space. [1] Most CAV systems are small, and serve a single thermal zone.
A typical whole-house fan, with louvers closed when not operating. A whole house fan is a type of fan, commonly venting into a building's attic, designed to circulate air in an entire house or other building. The fan removes hot air from the building and draws in cooler outdoor air through windows and other openings.
A panel heater is a type of electric convection heater commonly used for heating rooms in residential and small commercial settings. They are often mistaken for electric radiators , which are devices that use radiant heating and transfer heat directly to objects rather than using the air as a medium.
A central heating system has a furnace that converts fuel or electricity to heat through processes. The heat is circulated through the building either by fans forcing heated air through ducts, circulation of low-pressure steam to radiators in each heated room, or pumps that circulate hot water through room radiators. Primary energy sources may ...
Window fans are designed to fit into open windows, and often have expandable side panels to cover the entire window opening. Most units have either one large fan, or two small fans mounted side by side. [1] Most window fans have two or three speeds, and some are electrically reversible so that the user can switch between intake and exhaust modes.
The air column from a 3-foot-diameter (0.91 m) fan, therefore, has more than six times as much friction interface per volume of air moved as does the air column from a 20-foot-diameter (6.1 m) fan. [8] When the down column of air from an HVLS fan reaches the floor, the air turns in the horizontal direction away from the column in all directions.
