Convection heating is a process where heat is transferred through fluids, such as air or water, by the movement of the fluid itself. When a fluid is heated, it becomes less dense and rises, while cooler, denser fluid sinks. This creates a circulation pattern that distributes heat throughout the space, making it an efficient way to warm up an area. Common examples of convection heating include radiators and convection ovens. In a radiator, hot water or steam circulates through pipes, warming the air around it. In a convection oven, a fan helps circulate hot air, ensuring even cooking by distributing heat uniformly.
