Der Brenner 35 ist in einer Brennkammer 67 vorgesehen, welcher Brenner 35 mit einer Dichtung 66 gegen die Umgebung und den Ventilator 59 abgedichtet ist. Dem Brenner 35 wird über den Ventilator 59 ein vorgemischtes, homogenes Gas/Luft-Gemisch zugeführt. Die Luft wird vom Ventilator aus der Umgebung angesaugt. Das Gas wird mit einer nicht näher beschriebenen Vorrichtung mit Hilfe des durch den Ventilator erzeugten Unterdrucks der Luft zugemischt.3 shows a cross section of the heating unit 21 shown. The illustration shows those in FIG 2 modules shown. The burner 35 is in one Combustion chamber 67 provided, which burner 35 with a Seal 66 against the environment and the fan 59 is sealed. The burner 35 is switched on by the fan 59 a premixed, homogeneous gas / air mixture is supplied. The air is drawn in from the surroundings by the fan. The gas is not described in any more detail Device using the generated by the fan Negative pressure mixed with the air.

    Die Brennkammer 67 ist konzentrisch von einem glatten Rohr 46 des schraubenlinienförmigen Heißwasser-Wärmeübertragers 32 umgeben. Das glatte Rohr ist zur Minimierung des Durchtritts der Rauchgase zwischen dem glatten Rohr 46 und dem Doppelzylinder 34 so weit wie möglich ohne Zwischenraum gewickelt. Das glatte Rohr 46 geht mit steigender Rippenhöhe kontinuierlich in das verrippte Rohr 47 über, das sich in den abströmenden Gasen befindet, und geht wieder mit abnehmender Rippenhöhe in das Rohranschlußstück 48 über. Der Zufuhrsteckanschluß 49 ist mit einer geeigneten Abdichtung aus dem Rauchgasführungskanal 40 geführt, wobei die Abdichtung nicht dargestellt ist.The combustion chamber 67 is concentric of a smooth one Tube 46 of the helical hot water heat exchanger 32 surrounded. The smooth tube is for Minimize the passage of smoke between the smooth tube 46 and the double cylinder 34 as far as possible wrapped without space. The smooth tube 46 goes into that with increasing rib height finned tube 47 over that in the outflowing gases and goes back into it with decreasing rib height Pipe fitting 48 over. The feed connector 49 is with a suitable seal from the Flue gas duct 40 guided, the seal is not shown.

    Der Sanitärwasser-Wärmeübertrager 30 ist über den Flansch 44 in die Grundplatte 31 gesteckt. Der Sanitärwasser-Wärmeübertrager 30 kann einfach oder mehrfach aus glattem Rohr oder verripptem Rohr gewickelt sein. Für den Sanitärwasser-Komfort ist ein integriertes Energiepuffervolumen 65 an der Heizungsseite vorteilhaft. Die zur Ab- und Zufuhr von Sanitärwasser angebrachte Anschlüsse 61 bzw. 62 und die hinter einander liegenden Anschlüsse 63 und 64 zur Ab- bzw. Zufuhr von Heißwasser verlaufen parallel nach unten.The sanitary water heat exchanger 30 is on the Flange 44 inserted into the base plate 31. Of the Sanitary water heat exchanger 30 can be single or multiple be wound from smooth tube or ribbed tube. For the sanitary water comfort is an integrated Energy buffer volume 65 on the heating side advantageous. The attached for the supply and supply of sanitary water Connections 61 and 62 and the one behind the other Connections 63 and 64 for the discharge or supply of hot water run parallel down.

    Die Figuren 3a und 3b stellen mittels in dünnen bzw. dicken Linien dargestellten Pfeilen die Flüssigkeitsströmungsrichtungen von Sanitärwasser bzw. Heißwasser innerhalb des Sanitärwasser-Wärmeübertragers 30 dar.Figures 3a and 3b represent in thin or arrows depicting the thick lines Liquid flow directions of sanitary water or Hot water within the sanitary water heat exchanger 30 represents.

    In Figur 3a strömt über ein nicht dargestelltes Drei-Wege-Ventil Heißwasser über den Anschluß 64 durch ein bis oben in den Sanitärwasser-Wärmeübertrager 30 hineinragendes Rohr in den Sanitärwasser-Wärmeübertrager 30. Das Heißwasser umspült darauf eine doppelte glatte Wärmetauscherspirale 43 und verläßt den Sanitärwasser-Wärmeübertrager an der Unterseite durch ein Rohr über den Anschluß 63. Das Sanitärwasser strömt über den Anschluß 62 durch die außenliegenden Windungen der Wärmetauscherspirale 43 nach oben und anschließend durch die innenliegenden Windungen der Wärmetauscherspirale 43 nach unten und verläßt den Sanitärwasser-Wärmeübertrager 30 über den Anschluß 61.In Figure 3a flows through a three-way valve, not shown Hot water through connection 64 through one to protruding into the sanitary water heat exchanger 30 above Pipe in the sanitary water heat exchanger 30. The Hot water washes around a double smooth one Heat exchanger coil 43 and leaves the sanitary water heat exchanger at the bottom through a pipe over the Connection 63. The sanitary water flows through connection 62 through the outer turns of the heat exchanger spiral 43 up and then through the inside Turns of the heat exchanger spiral 43 down and leaves the sanitary water heat exchanger 30 via the Connection 61.

    In Figur 3b strömt über ein nicht dargestelltes Drei-Wege-Ventil Heißwasser im Prinzip auf die gleiche Art und Weise wie in Figur 3a in den Sanitärwasser-Wärmeübertrager 30. Die Wärmetauscherspirale 43 ist in Figur 3b im wesentlichen als ein verripptes Rohr ausgeführt, durch das das Sanitärwasser über Anschluß 62 nach oben und anschließend über ein gerades, glattes Rohr in dem zentralen Teil des Sanitärwasser-Wärmeübertragers 30 nach unten zum Abfuhranschluß 61 strömt.In Figure 3b flows through a three-way valve, not shown Hot water basically the same way and Way in Figure 3a in the sanitary water heat exchanger 30. The heat exchanger coil 43 is in Figure 3b in essentially run as a finned tube through which the sanitary water via connection 62 upwards and then over a straight, smooth pipe in the central part of the sanitary water heat exchanger 30 after flows down to the discharge port 61.

    Im Betrieb wird die Strahlungsenergie des Brenners 35 direkt auf die glatte Rohrspirale des Heißwasser-Wärmeübertragers 32 übertragen, wobei die Ausbildung mit einer kleinen Brenneroberfläche und einer großen Kühlfläche der Spirale des glatten Rohres in Zusammenhang mit einem kurzen Ausbrennweg einen vorteilhaften Effekt auf den zur Verfügung stehenden Leistungs-Regelbereich und die Stickstoffoxid-Emissionen hat. Das unter dem Brenner 35 angebrachte zylindrische Gehäuse 42 des Sanitärwasser-Wärmeübertragers 30 wirkt gleichzeitig als Verdrängungskörper für das verrippte Rohr 47 und als Wärmetauscher für einen Teil der Wärmeenergie aus der Brennkammer zum Energiepuffervolumen 65. Das sich um die Wärmetauscherspirale 43 herum befindende Heißwasser erhält demnach Wärmeenergie aus den Rauchgasen über die Aufheizung in den Rohren 46 und 47 und über das Gehäuse 42, welche Wärmeenergie an die Wärmetauscherspirale 43 übertragen wird. Der Querschnitt aus Figur 3 zeigt die Volumenverkleinerung der ganzen Einheit durch die Integration der Sanitärwasser-Aufbereitung.In operation, the radiant energy of the burner 35 directly onto the smooth spiral of the hot water heat exchanger 32 transferred, the training with a small burner surface and a large cooling surface the spiral of the smooth pipe in connection with one short burnout path has a beneficial effect on the Available power control range and the Has nitrogen oxide emissions. That under the burner 35 attached cylindrical housing 42 of the sanitary water heat exchanger 30 also acts as Displacement body for the ribbed tube 47 and as Heat exchanger for part of the thermal energy from the Combustion chamber for energy buffer volume 65 Heat exchanger coil 43 hot water located around receives therefore thermal energy from the flue gases via the heating in the tubes 46 and 47 and over the housing 42, which Transfer heat energy to the heat exchanger coil 43 becomes. The cross section of Figure 3 shows the Volume reduction of the whole unit through the Integration of sanitary water treatment.

    Der Doppelzylinder 34 ist mehrwandig ausgeführt. Der Außenzylinder 53 kann entfallen, falls die Isolierung 52 ausreichend fest ist.The double cylinder 34 is multi-walled. Of the Outer cylinder 53 can be omitted if the insulation 52 is sufficiently firm.
