The features and advantages of the invention will become apparent on reading the description which follows, given solely by way of example, and not by way of limitation, with reference to the following appended figures: FIG. 1: schematic representation of an example of a device according to the invention; FIG. 2: schematic representation of the device of FIG. 1, detailed at the connection interface at the inlet and the outlet of water; FIG. 3: schematic representation of a first example of water distribution apparatus intended to be connected to the device according to the invention; - Figure 4: schematic representation of a second example of water dispensing apparatus for connection to the device according to the invention.

The device, in the example shown in Figure 1, comprises a vessel 1 of substantially cylindrical shape, with a main wall 10 forming the body 10 of the cylinder, closed by two circular walls 12, 11 at both ends.

The walls 10, 11 and 12 comprise an inner layer, for example made of stainless steel, covered with one or more insulating layers consisting for example of polyethylene foam or injected polyurethane, and / or rock wool or compressed glass. A last outer layer 26 forms a jacket covering the aforementioned layers. It can be made of steel or thermoformed composite material or thermo-hardened.

Two or three connection blocks 2, 3, 17 are arranged on one of the end walls 11, 12, for example on the end wall 11. Two blocks 2, 3 of these blocks 2, 3, 17 are connection blocks or hydraulic connections.

Block 2 is a single block of water supply. It is intended to be connected to a water source. It allows to supply water to the tank 1 on the one hand, and water use a water pipe 7 on the other.

As can be seen precisely in FIG. 1, thanks to a schematic opening formed in the tank 1 for a purely explanatory purpose, this water pipe 7 is disposed inside the tank 1.

Preferably the use water pipe 7 takes the form of a coil 7, which may consist of one or more different windings, simultaneous or not, of different diameters or not, winding inside of the tank 1 from the wall 11 in which this coil 7 is sealingly connected to the single water inlet block 2, towards the opposite wall 12 and then returning by winding again towards the wall 11 in which this coil 7 is connected to the other block 3.

This other block 3 is a water outlet block 3. It is intended to supply water to a device 4, 5, such as one of the devices 4, 5 shown in FIGS. 3 and 4, or a distribution network. of water.

The use water pipe 7 is preferably made of copper or polytetrafluoroethylene (PTFE), of reduced diameter.

A heating means not shown in FIG. 1 is also disposed inside the tank 1. When this heating means is activated, for example by connection to a power supply by means of the electrical connection block 17 if This is an electric heating means, it heats the water contained in the tank 1 in which it is immersed.

Thus, the transfer of heat from the volume of heating water contained in the tank 1 to the pipe 7, allows the heating of the volume of use water contained in this water pipe, without direct contact between the water heating and use water.

The temperature of the heating water inside the tank 1 can be regulated by a thermostat, for example of the sensor type plunger.

Provision may be made for the presence of one or more gripping means, for example of the handle type, arranged on one or more of the walls 10, 11, 12 of the vessel 1, such as the handle 18 disposed on the outside of the wall 10 of the tank 1, to facilitate the transport of the device.

There is also provided an automatic drain 13 to purge the tank 1 of the heating water.

The device can be used in several different positions, while ensuring that the trap 13 is always placed in the upper part of the tank 1 for the proper operation of the purge, regardless of the position of use among the possible distinct positions .

Alternatively, the vessel 1 is preferably pre-drilled with a plurality of orifices, only one of which is effectively provided with a trap 13, the other orifices being plugged temporarily by plugs.

The tank 1 can be placed on a support 26. This support 26 can be formed integrally in the extension of the tank 1.

Fixation lugs may also be used to position the device in one or the other of the various possible positions of use.

As can be seen more specifically in FIG. 2, the heating water contained in the tank 1 is heated by a heating means 6, which takes the form of an electrical resistance 6 in this example.

This electrical resistance can be connected to a power supply via the electrical connection block 17.

Moreover, the water pipe 7 of use is connected in a sealed manner by a first end 8 to the single block of water inlet 2 and a second end 9 to the water outlet block 3.

Specifically, the single block of water inlet 2 comprises a water inlet 14 facing outwardly of the vessel 1, intended to be connected to an external water source materialized in Figure 2 by an arrow to the outside the tank 1 and oriented towards this tank 1.

This single block of water inlet further comprises a first water outlet 15 opening directly into the tank 1, which allows the permanent filling of this tank 1 in heating water, shown in Figure 2 by an arrow to the outside of the tank 1. This first water outlet may consist of a hole formed in the wall 11 of the tank 1.,

Furthermore, the single block of water inlet comprises a second water outlet 16 connected by means of a sealed connection 27 to the first end 8 of the water pipe 7.

As is shown in FIG. 2 by a solid arrow outside the tank 1 and oriented, the water contained in the pipe 7, thus heated by heat transfer from the heating water contained in the tank 1, itself heated by the heating means 6, is delivered by the second end 9 of the pipe 7, through the outlet block 3.

Specifically, the second end 9 of the pipe 7 passes through the wall 11 of the vessel 1, being sealed to this wall 11.

The device 1 may have different overall shape.

It can thus be connected to a hot water dispensing apparatus 4, 5, such as a shower 4 in the example of FIG. 3, or a sink 5 or washbasin 5 in the example of FIG. 4.

Specifically, the apparatus 4, 5 comprises a housing 21, 22 for receiving the hot water production device.

The housing 21, 22 defines a determined volume of shape, and the vessel 1 of the device then has a shape adapted to this specific shape of the housing 21,22.

This allows in particular to facilitate the insertion of the hot water production device in the housing 21,22, and also to optimize the size of the device 4, 5. The apparatus comprises one or more dispensing taps. 19, 20 connected to the water outlet block 3 of the hot water production device. The water inlet block 2 of this device is connected to a source of water. Finally, the heating means 6, such as the electrical resistance 6, is connected to an activation means, such as a power supply. The use water contained in line 7 of the hot water heat-heated device as explained above can thus be dispensed via the water supply tap 19, 20 of the apparatus 4, 5.

Preferably, the apparatus 4, 5 is provided with displacement means 24, 25, which take the form of wheels 24, 25 in the examples of FIGS. 3 and 4. These displacement means can for example be arranged under the housing 21 22.

The present description is given by way of example and is not limiting of the invention. In particular, the invention is not limited to a device whose vessel 1 would be cylindrical, or devices 4, 5 which would be of the washbasin or shower type.
