  • the combined device 10 gives rise to installation and connection difficulties. Indeed, the dimensions as well as the mass of the combined device 10 make it very difficult to handle by an installer. Indeed, the mass of the combined device 10 exceeds 55 kg when it is empty of water, which makes its handling by a single installer prohibited by the regulations in force. In particular, the combined device 10 weighs approximately 140 kg when it is empty of water and approximately 350 kg when it is filled with water. In addition, the combined device 10 measures approximately 1.80 m in height, which limits its positioning.
  • the first 22 and second 28 heat exchangers are housed inside the housing 34 which makes the dimensions of its outer envelope important.
  • the presence of the second heat exchanger 28 inside the storage tank 14 reduces the available interior volume. This imposes an oversizing of the storage tank 14 for a maximum desired domestic water volume inside the storage tank 14.
  • the storage tank 14 is therefore dimensioned with a larger interior volume compared to a storage tank. storage 14 without heat exchanger therein having the same internal volume available for storing sanitary water. The number and the volume of these components also lead to an increase in the mass of the combined device 10.
  • the large size of the combined device 10 and its large mass require installation of the combined device 10 on the ground. Indeed, it has been observed that for reasons of resumption of effort and simplicity of installation, it is not possible to suspend the combined device 10 above the ground.

  • connection of the combined device 10 to the heating members 20 and to the distribution of sanitary water 16 was not very easy because the position of each of the fittings is specific to the model of combined device 10.
  • the installation of heating water and sanitary water in room L depends on the model of combined device that will be installed in room L.
  • the installation of fittings the installation heating water and sanitary water in room L cannot be carried out easily upstream of the installation of the combined device 10. This greatly constrains the progress of the construction site, which therefore depends on the choice of the combined device.
  • this specificity of the position of the fittings of the combined device 10 complicates the work of the installer, which lengthens the installation time.
  • the fact of grouping the connections of the combined device to the heating water and domestic water installations of room L on the same plate makes it easier to read the connection of the combined device.
  • the installer does not have to look around the entire perimeter of the combined device where the different fittings are.
  • the positioning of the fittings on a plate gives the possibility of positioning each of the fittings at a standard position known to installers.
  • the installer can save a lot of time over the duration of the installation.
  • a predetermined position, both in height and vis-à-vis the other fittings, allows the installation of all the pipes of the domestic water and heating water installations of the premises even before knowing the model of combined device used or its installation.
