  • the water heater 100 includes an inner storage vessel 1 for storing heated Water, a housing 3 enclosing the inner storage vessel 1 and a heat insulating layer 4 filled with a foam (eg of polyurethanes) located between the inner storage vessel 1 and the housing 3.
  • the inner storage vessel 1 has a substantially cylindrical shape with a cylindrical wall and is usually made of ferrous metal such as steel or iron.
  • the water heater 100 is mounted horizontally, that is, the elongated wall of the inner storage vessel extends in the horizontal direction.
  • an inlet opening 11 for introducing cold water into the inner storage vessel and an outlet opening 12 for discharging hot water are formed in the wall of the inner storage vessel 1.
  • the water heater 100 includes a heat source for heating cold water, which may be different.
  • electric Wassererfflers may be present at one longitudinal end of the inner storage vessel 1, a flange (not labeled) on which an electric heating tube 2 is mounted, which projects into the water stored in the inner storage vessel.
  • This heating tube may include a high impedance resistance wire with the plus and minus terminals of the resistance wire on the flange and connected to a 220V or 110V AC power supply.
  • the liquid in the inner storage vessel for example, be heated by a combustion chamber arranged outside of this storage chamber in the case of a gas water heater.
  • the water heater 100 further includes a holder assembly which, together with a wall-mounted support member, serves to suspend the water heater to the wall.
  • the water heater includes two horizontally disposed holder assemblies. Since these are the same structure, only one of them will be explained in more detail below.
  • a retainer assembly includes an outer housing 51 for suspending the water heater on a wall and an inner retainer 52 mounted on the wall of the inner storage vessel.
  • the inner and outer retainers 52, 51 are made of metal.
  • the inner holder 52 can either be fixed in a manner known per se, for example by welding, to the upper wall of the inner storage vessel or by screwing to a transition sheet soldered to the wall.
  • the inner holder 52 is formed as a bent sheet metal part, for example made of sheet steel, which at its ends to the surface of the inner storage vessel is welded and forms in the middle of a rectangular elevation with a certain distance from the surface of the inner storage vessel.
  • a heat insulating assembly according to the inner holder 3 and 4 intended.
  • This includes a first heat insulating member 61 and a second heat insulating member 62 located on opposite sides 521 (indicated only once) of the inner holder 52.
  • the first heat insulating member 61 is disposed between the housing 3 and the inner holder 52, while the second heat insulating member 62 is located in a space of the inner holder 52 and the inner storage vessel 1.
  • the two ends of the first heat insulating part 61 are bent at right angles over the two opposite transverse ends 522 (indicated only once) of the inner holder 52 and extend downwardly to a respective hook-shaped latching part 611.
  • the second heat insulating part 62 comprises a base plate 621 and one on the base plate 621 opened, hexagonal nut-shaped recess 622 for receiving a nut 72.
  • On the base plate moreover, two semicircular strips are arranged around the recess 622, wherein in each case a latching hook 623 is attached next to the ends of each bar.
  • a cover plate 63 is provided which fits into the space enclosed by the strips.
  • this cover plate two opposite, radially extending tongues 631 are integrally formed, which secure together with the latching hooks 623 the respective position.
  • a spacer 64 Between cover plate 63 and nut 72 is also a spacer 64, see also Fig. 2 ,
