Abstract
A heat exchanger for swimming pools, formed of an essentially cylindrical housing through which a first medium flows axially, while a second medium flows through a conduit that is installed in the housing and that is fashioned as a coil. The coil-shaped conduit is formed of a corrugated hose, and has separate connections for the second medium, or for the corrugated hose. The corrugated hose is connected at its end segments to separate connections for the second medium via a plug connection. The connections extend from the outside to the inside of the housing, passing through the housing.
