Definitions

  • the invention relates to hot water heating according to the preamble of claim 1.
  • a heater as the name suggests, has a central boiler room in which there is a burner, a boiler and the necessary auxiliary units.
  • the water heated in the boiler can be used to heat radiators in one or more houses.
  • the heating room is generally placed in the basement. This demand for avoiding the undesirable local emissions of the heating in the living rooms was also pioneering in the development of single or multi-level stoves for central heating.
  • fireplaces provided with heat exchangers can, as described in CH-A 428139, have a transparent window for closing the combustion chamber. By closing the combustion chamber, the air supply and thus the burning speed of the fuel can be regulated and the heat exchange can be optimized.
  • fireplaces with heat exchangers and windows allow some of the heat generated in the fireplace to be recovered.
  • the connection of the heat exchanger to the central heating allows the recovered heat to be used for space heating. This warmth meets the warmth requirements of cold summer evenings and spring and autumn days. It also allows the room to be heated up more quickly thanks to its more direct effect and the additional heat radiation from the fireplace.
  • the fireplace / heat exchanger combination is only a spontaneous or secondary heating for individual rooms under the above-mentioned climatic conditions, in addition to the main or primary heating for the whole house or for the whole apartment, i.e. Central heating, can not be dispensed with.
  • the object of the present invention was to provide a hot water heater of the type mentioned initially functioning as a primary or main heater which, although it has a combustion chamber and a burner, i.e. has two flames, gets by with a heat exchanger and a hot water heating circuit and during their operation the cumbersome manipulations when lighting, extinguishing or re-regulating one flame are eliminated.
  • the object of the invention was to convert the fireplace in the living room into a primary heater, i.e. to combine the fireplace in the living room with the central heating from the basement, thus installing the burner in the living room.
  • the arrangement according to the invention of the boiler directly above the combustion chamber of the fireplace or open fireplace makes it possible to dispense with the second hot water heat exchanger and the corresponding second hot water heating circuit and thus with the cumbersome regulation manipulations that are required in the known primary / secondary heating systems.
  • the difference between the primary heating according to the invention i.e. The arrangement of the two flames separated by the boiler with a hot water heating circuit and the known separate arrangement of primary / secondary heating, each with its own heat exchanger and its own circuit for each flame, can be determined by the difference between parallel and series connection in of electrical engineering.
  • the inventive design of the heater as a closed water jacket allows the burner to be brought up from the basement into the living room, since the water jacket acts as heat and sound insulation.
  • the length of the hot water pipes and the heat loss are reduced, the length of the smoke outlet is shortened, a second smoke outlet and a second chimney on the roof are no longer necessary and a basement is released.
  • a preferred embodiment of the hot water heater according to the invention in which the boiler is arranged in a warm air space, allows the additional use of the heat radiated from the outer surface of the boiler during operation of the burner with the aid of warm air heating, the air streams of which run along this outer surface, heated and into the living space are delivered and bring about a corresponding improvement in the energy balance and more direct heating.
  • the device according to the invention offers particular advantages for heating smaller residential units, such as single-family houses and apartments, since it allows the setting of an individual heating output which is independent of the other members of a larger complex and is adapted to the personal needs of the residents. At the same time, it allows precise and simple individual billing of the heating output.
  • the present invention takes the opposite direction by allowing decentralization.
  • this decentralization leads to savings in heating material, installation and maintenance costs as a result of the parallel connection of two combustion processes, avoidance of line losses and heating according to individual needs.
  • the hot water heating in Figures 1 and 2 has a combustion chamber 1 in the form of a fireplace open to the front.
  • a horizontal heating boiler or heat exchanger 3 is arranged above the furnace in the lower part 7a of the smoke exhaust 7 and is designed as a closed cylindrical water jacket 4.
  • an oil burner (2) (Fig. 2) is arranged such that its flame projects into a horizontal flame chamber 5 formed by a closed cylindrical water jacket 4.
  • the flame chamber 5 is connected to the smoke vent 7 via an opening (not shown).
  • flaps 9 and 10 are arranged for guiding the flue gases (FIG. 2).
  • an extension of the heat exchanger 3 extends downward as a hollow wall 8 parallel to the rear wall 6 of the chimney 1.
  • a water inlet 16 opening into the hollow wall and for the heating water a water outlet 17 opening out of the water jacket 4.
  • the heating water circuit in the radiators with pump 18 and valves 19 is shown only schematically by dash-dotted lines.
  • the front opening of the fireplace is closed with a sliding window 12 sliding in rails 11 (FIG. 1).
  • the sliding window 12 is coupled to the burner 2 such that it is ignited only when the chimney opening is closed. This avoids heat loss due to excessive air throughput.
  • the sliding window is also coupled to the flaps 9 and 10 for guiding the flue gases in such a way that, when the sliding window 12 is open, the flaps 9 and 10 completely release the associated openings (dashed position), so that the flue gases can withdraw essentially unimpeded. If the sliding window 12 is closed, the flaps 9 and 10 assume a position which passes the flue gases between the rear wall 6 and the hollow wall 8.
  • the chimney rests on a base 20 which has a blower 21 and a drawer 22 on the side for receiving the ashes from the chimney 1.
  • a fuel basket 13 for e.g. Coal let in. If e.g. is fired with coal, for which an air supply from below is to be provided, the fuel basket is located in the combustion chamber 1. When not in use, it can be folded in the direction shown by arrow a and in direction b into a room 23 which holds the drawer 22 connects to the combustion chamber 1 in the base 20, can be pivoted downwards, after which it forms a firing grate 14 in the combustion chamber.
  • flaps 9 and 10 the heat exchange between the outer surface of the water jacket 4 and the flue gases.
  • the position of the flaps 9 and 10 allows the path of the flue gases and thus the intensity of the heat exchange to be regulated.
  • the heat exchange with the burner flame or with its flue gases takes place on the inner surface of the water jacket 4.
  • the water therein passes through the inlet 16 into the hollow wall 8, is heated and rises up into the water jacket 4, which it leaves in the heated state in the direction of the radiator .
  • the heat exchanger is arranged above the furnace 1 in a warm air space 24, in which the lower part 7a of the smoke exhaust 7 is also located.
  • the closed water jacket 4 of the heat exchanger 3 forms the cylindrical flame chamber 5 for the flame of the connected oil burner 2.
  • the flame chamber 5 is connected to the smoke outlet 7 via an exhaust pipe 7b.
  • Above the flame space 5, the water jacket 4 is penetrated by air channels 25.
  • the latter serve to improve the heat exchange of the air brought in by the blower 21 through the cavity 6a of the rear wall 6 with the outer surface of the water jacket 4.
  • the air heated by the heat exchanger 3 and / or by the lower part 7a of the smoke exhaust 7 leaves the warm air space 24 through the outlets 26 and then gets into the adjacent living room. It thus complements the performance of hot water heating or, if the furnace is operated alone, it can ensure the temperature of the living space by utilizing the heat generated. In both cases, it works within a short time and improves the energy balance of the system.
  • the shape of the lower part 7a of the smoke vent 7 shown in FIG. 4 has a cross-section corresponding to the combustion chamber 1, which narrows upwards. This shape is advantageous for the function of the smoke extraction as well as the heat exchange.
  • the combustion chamber 1 of the fireplace in Figures 2 to 5 is open on two sides. Its opening can be closed in the manner already explained in connection with FIGS. 1 and 2 with the sliding window 12 which may be coupled to the burner 2. In this case, the water inlet 16 and water outlet 17 of the heat exchanger 3 open side by side into the heat exchanger 3.
  • the hot water circuit 15 is only shown schematically in FIG. 3, as in FIG. 1.
  • the heat given off from the lower part 7a of the smoke exhaust 7 to the warm air space 24 can be used for warm air heating and / or for heating the heating water in the heat exchanger.
  • the arrangement of the heat exchanger 3 in the warm air space 24 according to FIGS. 1 to 3 allows the previously unused radiant heat of the central heating to be used and prevents local undesired overheating. This combination of hot water / hot air heating enables an optimization of the energy balance when heating living spaces.
  • the exhaust pipe 7b of the flame chamber 5 and the smoke exhaust 7a of the combustion chamber 1 can lead to a common smoke exhaust or separate smoke exhaust.
  • the burner 2 and its auxiliary units can be in the same structural unit as the other elements of the heating or preferably separated therefrom, e.g. be housed in an assembly or service cabinet. In any case, you have to do the revision, e.g. through a door, be easily accessible.
  • the air supply to the warm air space 24 does not have to be through the cavity 6a in the rear wall 6, but can be provided by other parts of the heater.
  • a pivotable window can also be provided.
