  • an intermediate jacket arranged between the outer jacket and inner jacket which is formed and arranged between the inner jacket and the outer jacket such that channels are formed in the intermediate space between inner and outer jacket in which fluid for heating and heating fluid can be fed through such that heat exchange takes place between these two fluids.
  • Two helical channels are preferably formed through the intermediate jacket so that after arranging of the intermediate jacket between the inner and outer jacket no further actions have to be performed to obtain heat exchange between the two fluids .
  • the intermediate jacket is welded and/or soldered fixedly to the inner and outer jacket, which can be realized easily and at little cost.
  • the present invention further provides a method for manufacturing a device for storing and/or heating fluid, comprising the following steps of:
  • the present invention provides a device for discharging gaseous medium from a fluid flow, comprising: - a first channel for fluid possibly provided with gaseous medium;
  • the gas bubbles can escape in the direction of the vent through the secondary channel .
  • the fluid possibly carried along in the direction of the vent is then entrained once again in the main flow of the fluid.
  • the venturi action in the channel is also brought about by a deflecting member whereby the fluid flow is deflected.
  • the device according to the present invention is preferably provided in a second preferred embodiment with a fluid forcing means behind which a suction conduit of a pump of standard make is preferably arranged.
  • fig. 1 shows a front view, partly in cross- section, of a combi-appliance, wherein a device according to the present invention can be applied
