Definitions

• the present invention relates to a heater, comprising a heating body formed by an assembly of several walls among which a rear wall, delimited by an edge, closes the heating body to the rear, an outlet for the burnt gases, and possibly a passage, which is provided in the rear wall and in which an air inlet is arranged.
• a heating appliance such as gas appliances, in particular of the chimney type or of the suction cup type, liquid fuel appliances, in particular of evaporation under pressure or gasification under atmospheric pressure. , wood appliances and solid fuel appliances. This list is obviously not exhaustive.
• These devices generally have a rear or back wall, which can be made of cast iron, steel, refractory earth or a similar material, and which is attached to the rest of the heating body by means known per se. Any healthy heating appliance also requires an intake of combustion air and an outlet for the burnt gases.
• Stoves are also known which, by a change in the internal equipment, are suitable for burning several types of fuel (see for example US-A-4258692 and FR-A-553427).
• a coal-fired heater is known, the rear wall of which is formed by three sections, the central section being removable and allowing easy access to the discharge flues, and therefore their cleaning (see for example FR-A-709454).
• the present invention aims to solve these problems, and in particular to facilitate storage and reduce the cost of the "technical" part of heating appliances.
• a heating apparatus as described at the start which further comprises - An opening in the rear wall, opening which is provided with a peripheral edge situated at a distance from the edge of the rear wall and which has standard dimensions, predetermined for a given power of the heating appliance, but without regard the model of the fuel or the fuel it uses, and
• an intermediate piece of standard shape depending on the fuel used, which is adapted in the aforementioned standard opening, so as to close it in leaktight manner, and which has a passage orifice allowing communication between the interior of the body of heating and said outlet for the burnt gases, possibly by means of evacuation of the burnt gases. It is thus possible, whatever the model of domestic stove envisaged, to provide in the rear wall a standard opening which is suitable for all types of heating apparatus of a given power.
• An intermediate piece appropriately supporting the equipment allowing for example the evacuation of the burnt gases, various thermal exchanges or a regulation of the draft, is then adapted in the standard opening, part whose shape will correspond to the heating appliance. ⁇ to assemble, whether it is of the wood or rather charcoal type or another. Only the shape of this intermediate piece, of reduced size, will vary in order to receive said equipment.
• an intermediate piece and the corresponding equipment are adapted in the above-mentioned opening.
• the manufacturer can thus provide for all its fuel oil stoves with a given power, present and future, an intermediate piece equipped in particular with a heat recovery unit which will always be the same, even if the fashion evolves. This obviously results in a quite remarkable ease of storage and a lowering of the manufacturing costs of the technically useful parts of the stoves, since they can be manufactured in any large series.
• the present invention also covers an intermediate piece to be adapted in the opening of the rear wall of a heating device according to the invention.

• identical or analogous elements are designated by the same references.
• the heating appliance shown is an oil stove 1, the heating body of which has several walls. Only a fragment of the rear wall 2 is shown.
• This rear wall 2 has a limit edge 40, 40 ′, 40 ", and, during assembly with the other walls of the heating body, it is intended to close the heating body on the rear side.
• this is, in a known manner, divided into two by means of a bottom plate 3.
• This supports, downwards, a known liquid fuel gasification pot, not shown, and in which opens a combustion air inlet, which passes through a passage 4 provided at the bottom of the rear wall 2.
• the rear wall 2 is in its upper part also provided with an opening 6, the peripheral edge 41 of which is located on all sides at a distance from the limit edge 40, 40 ', 40 "from the rear wall.
• This opening has standard dimensions for all stoves of the same power.
• a room tab 7 which closes it.
• the intermediate piece 7 has a passage orifice 8 for the burnt gases, an orifice which allows communication between the interior of the heating body and means for evacuating the burnt gases.
• the intermediate piece has a shape suitable for use in an oil stove and it supports a housing 9 which has an inlet opening 10 for the burnt gases, which is fitted in the passage orifice 8 of the intercalated part 7, and an outlet opening 11 to which is connected here a nozzle 12, which, in turn, can even be attached to a chimney flue for example.
• a nozzle 12 which, in turn, can even be attached to a chimney flue for example.
• FIG. 1 In the lower part of the housing 9, one can observe in FIG. 1 an additional opening 13, which places the interior of the housing 9 in communication with the external environment. In this opening
• valve optionally adjustable, which is not shown and which serves as a draft regulator or draft cut-off and which, depending on the circumstances, allows air to enter the housing 9.
• the housing 9 is supported by the insert 7 so as to leave free a slight gap between these two elements.
• the external face of the intermediate piece 7 is provided with fins promoting heat exchange. The intermediate piece 7 thus supports a heat recuperator where the air entering
