Die Erfindung betrifft eine Vorrichtung zum teilweise Aufheizen des Rücklaufwassers einer Zentralheizungsanlage vor Wiedereintritt in den Heizkessel. The invention relates to a device for partially heating the return water of a central heating system before re-entering the boiler.
Bei den bisher bekannten Zentralheizungsanlagen entweichen die heißen Rauchgase aus dem Heizkessel wärmetechnisch unausgenutzt in den Schornstein. Dadurch geht Wärmeenergie verloren, die im Heizungssystem zumindest teilweise ausgenutzt werden kann. In the previously known central heating systems, the hot flue gases escape from the boiler thermally unused in the chimney. As a result, thermal energy is lost, which can at least partially be used in the heating system.
Die vorliegende Erfindung hat sich daher die Aufgabe gestellt, eine Vorrichtung zu schaffen, die es ermöglicht, zumindest einen Teil der im Rauchgas des Heizkessels vorhandenen Wärmeenergie für das Heizungswasser nutzbar zu mächen.The present invention has therefore set itself the task of creating a device that it enables at least part of the existing heat energy in the flue gas of the boiler for to make the heating water usable.
Zur Lösung dieser Aufgabe wird eine Vorrichtung vorgeschlagen, welche gekennzeichnet ist durch eine um das Rauchgasabzugsrohr geführte Rohrspirale, deren Enden an die Wasserrücklaufleitung anschließbar sind und die Rohrspirale außen mit einer Wärmeisolierung ummantelt ist.To solve this problem, a device is proposed which is characterized by a pipe spiral guided around the flue gas outlet pipe, the ends of which are connected to the water return pipe can be connected and the spiral pipe is sheathed with thermal insulation on the outside.
Die Vorteile, die mit der Erfindung erreicht werden, bestehen darin, daß das aus dem Heizungssystem in die Heizflächen des Heizkessels zurücklaufende abgekühlte Wasser vor Eintritt in den Heizkessel durch die um das Rauchgasabzugsrohr geführte R.ohrspirale geführt wird und dort eine teilweise Aufwärmung erfährt. Durch die äußere Ummantelung der Rohrspirale mit einer Wärmeisolierung wird die vom Rauchgasabzugsrohr abgestrahle Wärme im Bereich der Rohrspirale gestaut, so daß das durch die Rohrspirale rückfließende HeizungswasserThe advantages that are achieved with the invention are that from the heating system Cooled water flowing back into the heating surfaces of the boiler before it enters the boiler through the pipe spiral led around the flue gas exhaust pipe is performed and experiences a partial warming up there. Through the outer sheathing of the Spiral pipe with thermal insulation is the heat radiated from the flue gas exhaust pipe in the area the spiral pipe dammed, so that the heating water flowing back through the spiral pipe

This largely depends on the piping and the space available, since the inventive Device is also intended for subsequent installation.
Die erfindungsgemäße Vorrichtung wird in einem Ausführungsbeispiel anhand der Zeichnung nachfolgend beschrieben.The device according to the invention is described below in an exemplary embodiment with reference to the drawing described.
Der Heizkessel ist mit 1 bezeichnet. Er besitzt eine Vorlaufleitung 2 und eine Rücklaufleitung 3· Die Rauchgase des Heizkessels 1 gelangen über das Abzugsrohr 4 in den Schornstein 5· Um dasThe boiler is denoted by 1. It has a flow line 2 and a return line 3 The flue gases from the boiler 1 reach the chimney 5 via the flue pipe 4
Abzugsrohr 4 ist eine Rohrspirale 6 gelegt, die an die Rücklaufleitung 3 angeschlossen ist. Die Rohrspirale 6 ist außen mit einer Wärmeisolierung 7 ummantelt. Die Anschlüsse der Rohrspirale 6 gemäß dem Ausführungsbeispiel sind derart, daß das eine Ende 8 an die Rücklaufleitung vor dem Mischventil 9 und das andere Ende 10 der Rohrspirale 6 hinter dem Mischventil 9 an die Rücklaufleitung 3 angeschlossen ist. Vie oben erwähnt, besteht aber auch die Möglichkeit, daß nicht eine Teilmenge des Rücklaufwassers sondern die gesamte Menge durch die Bohrspirale geführt wird. A pipe spiral 6 is placed on the exhaust pipe 4 and is connected to the return line 3. The spiral pipe 6 is sheathed on the outside with thermal insulation 7. The connections of the spiral pipe 6 according to the embodiment are such that one end 8 is connected to the return line upstream of the mixing valve 9 and the other end 10 of the spiral pipe 6 is connected to the return line 3 downstream of the mixing valve 9. As mentioned above, there is also the possibility that not a portion of the return water but the entire amount is passed through the drilling spiral .
