What is a convection heater?

A convection heater is a type of heater that uses convection to transfer heat through the movement of gas or liquid. A convection heater works similarly to a convection oven and is different from conduction or radiant heating since it relies on air movement. It functions by warming your room from the top down. A convection heater depends on the air properties to rise when warm and fall when cool. Unlike radiant heating systems that utilize electromagnetic waves to transmit heat, convection heaters use the air itself. The process involves convection currents moving throughout the body of the heater and across the heating element. The heat produced is transmitted to the surrounding air, causing the heated air to expand and rise. Naturally, hot air has a lower density compared to cool air. This is among the most essential concepts in convection heating. While heated air rises and displaces your room temperature air, the cooler air comes into contact with your convection heater. As a result, it gets heated up as well. The process then repeats itself, hot air rises, your room temperature air gets displaced near your heater. This process repeatedly happens until you turn off your convection heater, either through an automatic shut off if your heater has that feature. Automatic convection heaters turn off once the desired room temperature has been achieved. Also, some convection heaters are designed with a fan to speed up drawing in cool air and distributing heated air. Convection heaters are the most efficient types of heaters for whole-room heating.
