Heat transfer depends upon the heat conductivity of both your heating …

WebNot necessarily because heat can move in any direction. For example, if your living space is 70 degrees and your unconditioned basement is 52 degrees, the heat in your living space will move downward, since heat moves from a warmer space to a cooler space. Heat transfer occurs in three different ways: conduction, convection and radiation. WebThere are three basic mechanisms of heat transfer: conduction, convection, and radiation. Heat transfer by conduction is described by Fourier's first law, which states that positive heat flow occurs in the direction of decreasing temperature.
