Abstract
Installation for the sterilization of a body of water wherein the water is conveyed through a heat exchanger to a heat source, where it is heated up to the sterilization temperature. This stream of hot water transfers its heat to the incoming stream of water, leaving the heat exchanger at a temperature that is only slightly higher than that of the incoming water.

Counter flow heat exchanger with a heating element to sterilize a flow of water by heat with an inlet opening and an outlet opening, comprising a ring-shaped outer wall (1) and two endplates (2) with a heating element (11) positioned near the center of the ring-shaped outer wall (1), having a first heat transferring separaton-wall (15) that forms with a second heat transferring separation-wall an elongated inwardly spiraling first channel (13) which starts at the inlet opening and ends close to the heating element (11) where the flow of water absorbs its heat, and with a second outwardly spiraling channel (14) that starts close to the heating element (11) and ends at the outlet opening, whereby the heat transferring separation-wall (15) conducts heat from the second channel (14) to the first channel (13) thus preheating the newly entering flow of water.
