Abstract: A method and apparatus for supplying a heated fluid to a heat consumption circuit, such as an injection mold. The apparatus comprises a heat exchanger, for heating the fluid, a pump for pumping the heated fluid to the heat consumption circuit, a reservoir for storing the fluid, and a degasifier for degasifying the fluid that returns from the heat consumption circuit to the apparatus.

In addition, the connection between the degasifier and the reservoir is in the form of a siphon which acts as a thermal barrier to prevent the heat from the heated fluid from heating the fluid in the reservoir. As a result of this arrangement, the total volume of fluid used is much smaller than in prior art devices, thereby substantially decreasing the heat losses from the fluid to the environment.

An expansion engine is located inside the casing and may be designed as a high-speed turbine or as a high-speed displacement motor.
