A heating apparatus (2) draws in a liquid medium through a motor (7) driven, high pressure pump (5, 172), the liquid medium is greatly increased in pressure and temperature through frictional heating thereof and then the liquid medium is discharged in a heated, reduced pressure state for use directly or for heat exchange with another fluid. A method of utilizing the heating apparatus is also disclosed.

[ I claim:] [1.] An apparatus for heating a liquid medium comprising:a liquid passage;means for drawing a liquid medium into said liquid passage at a first pressure and a first temperature;means for retaining said liquid medium in said liquid passage until said liquid medium is pressurized to a second pressure which is multiple times higher than said first pressure and frictionally heated to a second temperature which is greater than said first temperature;means for releasing said liquid medium in a heated state from said liquid passage at a third pressure which is lower than said second pressure;means for sensing an operating parameter related to at least one of the second temperature and the second pressure of said liquid medium;means for automatically controlling the operation of said drawing means based on the sensed operating parameter;a reservoir from which said drawing means receives said liquid medium;a closed circuit heating system including a first heat exchanger, a compressor and a second heat exchanger;a blower unit positioned adjacent said second heat exchanger; andmeans for driving said compressor and said blower unit, said driving means including at least one fluid motor adapted to receive a supply of said liquid medium from said drawing means.
