A convection heater provides heat to an area by heating the air using air convection currents that circulate inside the body of the heater. The heater works by pushing air through a heating element. After the air absorbs heat, it is blown from the heater into an open area.
A convection heater is generally quieter than fan heaters and can incorporate different heater elements, including hot water coils, electrical components or steam coils. In most heaters, an internal fan is used to blow air through the heating element into the designated area. This type of heater utilizes draft construction, which pulls cool air into the device, then heats the air before pushing it out. This is a form of radiant heat that allows the heater to operate continuously while maintaining a cool exterior.
After the air is heated, it circulates the room and raises the surrounding temperature until the thermostat recognizes a temperature goal and turns off the heating element. This process continues until the entire area receives an even layer of warmth. Convection heaters are available in various shapes, sizes and price ranges. These heaters typically have a number of innovative features. Some heaters oscillate, which allows the air to circulate the room more effectively.
