modular element.

  According to this addition, the additional modular element of improved heating, intended to be fitted on the top of a traditional generator for producing hot water for central heating, such as a central heating boiler -2- or a thermal accumulator hydroaccumulation, according to one

  claims of the main patent, of the type constituted by

  a chamber forming a reservoir in which can circulate

  hot water from said generator, said enclosure comprises

  the generator enclosure to the return circuit of the central heating

  when the generator is turned on.

  In practice, this modular element: - is integrated with the generator and possibly the domestic hot water tank inside a bodywork common to all elements, - is surrounded by a thermal insulation on all its components.

  this insulator is also placed all around the gen-

  and possibly hot water storage tank

  electric heating elements, so as to realize a

  hot water supply called "instantaneous"; - in the summer, for the sole production of domestic hot water, the electrical power of the module dedicated to this production is only a fraction of its nominal power - the flow of hot water to the central heating is

  disposed either on the top of the hot water tank

  integrated hot water system to allow

  hot water called "instant".

  This spiral-shaped coil 35 is placed either around this heating element (see FIGS. 5 and 6, respectively seen in section and seen from above), or above this element.

  in which the modular element is directly connected

at the central heating circuit.

  FIG. 10 shows another embodiment of the invention in which this modular element 10 comprises a so-called "instantaneous" hot water production produced by a spiral-shaped coil 35 placed in

  the enclosure 1 around the electric heating elements 3,

  connected to the domestic hot water circuit 18, 19.

  Finally, Figures 11 to 14 show the diagrams

  wiring harnesses of generator set 11-15, module 10

  and if there is a balloon 16 or coil 35.

  So that the water to be heated circulates in the best conditions around all the electrical elements,

  advantageously the sleeve 26 is extended by a tube to the in-

  Inside the enclosure 1. Different holes along this

  tube, allow to distribute the water in said enclosure 1.

  On the other hand, baffles can be placed inside this enclosure 1 so as to channel the circulation of

  water around the electric heating elements.

  Referring to the figures, the equipment according to the invention

  consists of a traditional hot water generator

  for any type of central heating (fuel,

  liquid, solid or gaseous) 11 or a hydroaccumulation heat accumulator 15. This generator has on the top a threaded sleeve 5 disposed on the upper face of sQn enclosure for connecting the hot water circuit of said generator to the modular element 10 described in the main patent and heated by the horizontal electrical elements 3. In order to improve the rigidity of the assembly, at least one spacer 37 isfixed by welding on the underside of the module 10

  and on the top face of the generator 11-15.

  In the lower part of the enclosure of this traditional generator

  11 or 15, is placed a conventional connection 20 connected to the cir-

  cooked back 24 of the central heating 22. A control valve

  Three-way mutation 25 is placed upstream of said connector 20.

  The modular element 10 electrically heated by the horizontal elements 3, such as for example by means of candles formed by resistors embedded in rooms

  in ceramic enclosed in a sealed tube or by thermo-

  moulders, present on the top and in the center a flange

  6 connecting it to the bottom of ur. tank 16 of domestic hot water.

  This tank 16 further comprises a cold water inlet 17, -6-

  a connection to the expansion vessel 18 and a hot water outlet

  sanitary 19. The reference 13 designates a conventional connection connected to the conduit 23 of hot water flow to the central heating symbolized by the reference 22 whose return circuit is referenced 24.

  This return circuit 24 is connected to a switching valve

  The three-way connection itself is connected in turn to the connection via the conduit 28 and another conduit 29 to the connector 26, such as a threaded sleeve, disposed at the base of one of the side faces 27 of the connector. enclosure 1 of the modular element 10. This

  three-way switching valve 25 is controlled by means of a

  electrical unit 30 associated with either the operating command

  Reference 31 designates an insulating material such as

  for example, glass wool, placed between the

  of the modular element 10 and the upper part of the generator 11 or 15 so as to avoid leakage

  of the element 10 to the generator 11. The genera-

  11 having, by design, a large peripheral area and being, on the other hand, in the case of an oil, gas, propane, wood or coal boiler

  in conjunction with a chimney, is an important source

carrying loss.

  The insulating material 31 is also placed all around the generator 11, 15 of the module 10 and possibly, if

  exists, the hot water production tank 16.

  All this set is placed inside a

bodywork 38.

  as described above, may be

  manual operation when working with wood or coal.

  This shutter is closed when the generator is not in operation.

ment.

  The embodiment according to this certificate of ad-

  the advantage of automatic operation of a very high reliability whatever the fuel or

  the generator module combination retained.

  When the electrical module is in operation, it makes it possible to prevent heat loss through the internal surface of the generator, which is constituted by a

  boiler or a heat accumulator with hydroaccumulation.

  It also avoids heat losses

  by air circulation inside the enclosure of the genera-

  and drive calories to the chimney when it comes to a boiler. Finally, the arrangement according to the invention reduces the volume of water to be heated, since the water located in

  the generator enclosure is no longer in circulation.

  As already stated, the insulator 31 is advantageously placed between the inside face of the generator enclosure 10 and the

  upper face of the generator enclosure 11, 15.

  In a variant shown in FIG. 2, the modular element

  10 may have a connection 32 or 32 '(left or right) to be switched to the conduit 23 of hot water from the central heating 22 disposed on the same side face 27 of the chamber 1 and which is in this case intended to replace the previous connector 13 which is not then used. This mode of

  connection can be retained when it is desired that the time

  hot water temperature is not changed and disturbed

  by the water temperature of the central heating circuit.

  Likewise, in practice (see also FIG. 2), it is possible to have a right-hand and left-handed return fitting 26 'which, at the choice of the installer, will be obstructed or connected to the return circuit 29 (depending on whether the we are dealing with an installation Q0594 -8-

right or left).

  If it is desired to improve the heat exchange inside the modular element 10, and if it is better to distribute within this modular element the circulation of hot water and avoid overheating in certain places of this

  modular element, it can be arranged inside the

  1 or baffles, or extend the sleeves 26 or 26 'by a tube 36 so that the water inlet is inside the chamber 1 opposite the starting connection 32 or 32 'or flange or fitting 6. In this case, holes are drilled - along this inner tube 36 to

  distribute the introduction of water inside the enclosure 1.

  The connector 26 is placed on the bottom of the side face 27 of the enclosure 1. But if the more generally this connection is placed on the right or left side face 27 for ease of connection, it can also be placed on the

  rear side 27 (see Figures 3 and 4).

  Figure 9 shows an embodiment without reser-

  of domestic hot water production 16. In this

  In the embodiment, the top fitting 6 of the modular element is then directly connected to the conduit 23 of the circuit.

departure of the central heating.

  FIGS. 5 to 8 show respectively, in section and in plan view, two embodiments in which the production of hot water is no longer carried out by

  a balloon 16 located at the upper part of the modular element

  10 but by a coil-shaped tube 35 placed in the element 10 either around the horizontal heating elements 3 (Figures 5 and 6), or above these elements

  heaters 3 (Figures 7 and 8). These embodiments

  feel the advantage of leading to less

  costly and cheaper than a traditional balloon 16.

  In the configurations corresponding to these FIGS. 5 to 8, the connection start 18 with the expansion vessel is therefore no longer necessary. The connection 6 being placed in the upper part of

  generator set 11, 15 to which is added the modular element

  10 horizontal electrical dulaire, the expansion tank is in

  this configuration connects to the circuit 23.

  The commissioning or shutdown of the element 10 and the generator 11, 15 depend either on current charging.

  electric or even outside temperature.

  In the first case, this change of tariff is caused, in remote control, by a pulse on the initiative of the supplier of current. This pulse is controlled by a relay 42 placed on the subscriber board, said relay is electrically connected to another relay 50 of the control cabinet of the module 10-generator assembly 11 or 15, thus enabling

  starting or stopping the module 10.

  If the generator 11 is a fuel-burning boiler

  quide or gaseous, this generator is operated when

  the module is shut down and vice versa.

  If the generator 11 is a solid fuel boiler

  of, as previously, the start-up or shutdown of the module 10 is caused by remote control in the same way, but in addition the control cabinet allows the user, when the remote control puts the module 10 to stop, maintain it in operation by the manual selector 41 if it does not wish

  do not put into operation the solid fuel generator 11.

  On the other hand, if the user wishes to privilege the operation on solid fuel, the control cabinet only allows the operation of the electrical module 10, if the temperature of the water of the central heating circuit is at the outlet said generator, lower than a threshold set by the probe 43 located on the generator. 1

  If the generator 15 is a hydroaccumulator

  linked to an external source of heat, which can be for example a solar panel, the process is identical

  to the one just described for the fuel generator

tible solid.

  In the second case where the

  temperature outside the dwelling to be heated, this

  edition is only optional and not imperative. It does not

  11, when said generator 11 is a boiler with

  liquid or gaseous fuel. In this case, when the temperature

  also controlled by a temperature sensing probe

  When the temperature exceeds this threshold, the process reverses the operation of the electrical module 10 and turns on the generator 11. When the temperature rises above this threshold, the process is reversed. The design of the control cabinet allows the power of the motor 30 of the valve 25 and the probe 43 for detecting the temperature of the water to be turned on or not in the enclosure of the generator 11 when the latter is either a solid fuel boiler or a hydroaccumulation heat accumulator;

their enclosure.

  When domestic hot water production is associated

  the electric modular element 10 is used.

  This configuration reduces the level of electrical power subscribed by the user. It accordingly decreases the amount of its fixed subscription. On the other hand, it allows electricity consumption to be reduced during the coldest periods, during which time

  the electricity supplier is faced with the demands of

the strongest.
