Abstract
A fluid flow machine consisting of a stator, mounted underneath a hot water tank, and an armature-impeller unit arranged inside said hot water tank, being separated from said stator by a spherical, magnetically permeable separation wall, which generates a toroidal vortex inside the water tank. Said vortex conveys hot water from the upper region of the tank to its lower region until the whole tank is filled with water of a uniform temperature.
