heat flows from warmer objects or areas to cooler objects or areas

heat is a bi-product of molecular movement... the more the molecules move the more heat that its created.... since all molecules want to be as stable as possible at all times... they move around trying to find a sable for while in the process creating polar regions which affect nearby molecules which start to move also until all heat is dissipated.
Heat always moves from Hot to cold. Think about your hands in winter...the heat moves out of them because the weather is so cold....you put them on a radiator because it's hotter so the heat moves into your hands. Heat moves from Hot to Cold.

Heat always flows from warmer objects to cooler objects, unless you have a device (like a heat pump) to prevent this. The natural tendency is for two or more objects at different temperatures to eventually all have the same temperature and this is accomplished by heat flowing from the warmer objects to the cooler objects.
Heat can usually be considered as the energy of motion of atoms and molecules. Heat can flow spontaneously only from warm to cold. Heat can be made to go in the other direction, but only by doing work. So, the simple answer is: from warm to cold.
Heat flows from warmer to cooler.

Conduction and radiation. Heat always flows from the hotter of two objects into the colder - until their temperatures are the same.
