Dear Siddharth,
Heat transfer in engineering consists of the transfer of enthalpy because of a temperature difference. Enthalpy is the name for heat energy, to distinguish it from other sorts, such as kinetic energy, pressure energy, useful work. There has to be a temperature difference, or no heat transfer occurs.
(If we insist on moving enthalpy from a cold body to a hotter one, we will have to do extra work, as in the case of a refrigerator. This invariably involves some other process, such as mechanical work, and cooling by expansion of gases, but within the overall activity heat transfer always goes from the hotter to the cooler.)
The temperature difference is called the driving force. Other things being equal, a greater temperature difference will give a greater rate of heat transfer.
