Description
Warmwasserspeicher mit Mischvorrichtung Hot water tank with mixing device
Beschreibung description
Hintergrund der Erfindung Background of the invention
Die vorliegende Erfindung betrifft einen Warmwasserspeicher zum Bereitstellen von Warmwasser. Der Warmwasserspeicher umfasst einen Wasserzulauf zum Zuführen von Kaltwasser, einen Wasserablauf zum Abführen von Warmwasser und eine Mischvorrichtung zum Steuern der Temperatur des abgeführten Warmwassers. The present invention relates to a hot water tank for providing hot water. The hot water tank comprises a water inlet for supplying cold water, a water outlet for discharging hot water and a mixing device for controlling the temperature of the discharged hot water.
Stand der Technik State of the art
Aus dem Stand der Technik ist beispielsweise die DE 37 27 442 A1 bekannt, in der ein Verfahren zur Erzeugung von Warmwasser in einer Warmwassererzeugungsanlage offenbart ist. Um einen hygienischen Betrieb der Anlage zu ermöglichen, ist der Warmwassererzeuger derart ausgebildet, dass das zugeführte Frischwasser auf einer Temperatur oberhalb 60° während der Nichtentnahme von Warmwasser erwärmt werden kann. Folglich werden die Wasserleitungen mit heißem Wasser durchgespült, um die Bildung von Legionelen-Bakterien, welche gesundheitsschädlich sind, zu unterdrücken. Dieses Durchspülen wird wegen der Energieeffizienz periodisch und nicht dauerhaft ausgeführt. Durch die Trägheit der beschriebenen Anlage, können im Falle einer Entnahme von Warmwasser während des Durchspülens, sehr hohe Wassertemperaturen auftreten, welches zu einer Verbrennung eines Benutzers führen kann. Dies entsteht daher, da die Temperatur des Wassers während des Durchspülens oberhalb von 60° liegt. From the prior art, for example, DE 37 27 442 A1 is known in which a method for producing hot water is disclosed in a hot water production plant. In order to enable a hygienic operation of the system, the hot water generator is designed such that the supplied fresh water can be heated to a temperature above 60 ° during the removal of hot water. Consequently, the water pipes are flushed with hot water to suppress the formation of Legionelen bacteria, which are harmful to health. This flushing is performed periodically and not permanently because of energy efficiency. Due to the inertia of the system described, very high water temperatures can occur in the case of removal of hot water during flushing, which can lead to the combustion of a user. This arises because the temperature of the water during the flushing is above 60 °.
Die G 93 04 262 U1 offenbart ebenfalls eine Warmwasseranlage, die zusätzlich mit Hilfe von Sonnenkollektoren betrieben wird. Um Warmwasser jederzeit bereitstellen zu können, weist die Anlage einen Durchlauferhitzer auf, welcher das Wasser, welches vorher durch die Sonnenkollektoren durchfließt, empfängt. Falls das Wasser bereits durch Sonnenenergie eine zu hohe Temperatur erreicht hat, wird eine Kaltwasserbeimischung vorgeschlagen, damit der Durchlauferhitzer nicht beschädigt werden kann. Hingegen
offenbart die DE 195 30 000 C2 eine Warmwasserbereitungsanlage, welche den Durchlauferhitzer nur dann in Betrieb nimmt, falls das Wasser, welches durch die Sonnenenergie erwärmt wurde, einen bestimmten Temperaturschwellwert unterschreitet. The G 93 04 262 U1 also discloses a hot water system, which is also operated by means of solar panels. In order to provide hot water at any time, the system has a water heater, which receives the water, which flows through the solar panels before. If the water has already reached too high a temperature due to solar energy, a cold water admixture is suggested, so that the water heater can not be damaged. On the other hand DE 195 30 000 C2 discloses a hot water preparation system, which only takes the instantaneous heater into operation if the water which has been heated by the solar energy falls below a certain temperature threshold value.
Demzufolge haben alle bekannten Anlagen einen gemeinsamen Nachteil, dass das Wasser, welches dem Benutzer zur Verfügung gestellt werden soll, starken Schwankungen unterliegt und keine konstante Austrittstemperatur an der Entnahmestelle gesichert werden kann. Auch ist die Energieeffizienz der üblichen Anlagen nicht optimal, da ständige Temperaturregelungen stattfinden müssen, welche wiederum einen hohen Energieverbrauch verursachen. Consequently, all known systems have a common drawback that the water which is to be made available to the user, subject to strong fluctuations and no constant outlet temperature can be secured at the sampling point. Also, the energy efficiency of conventional systems is not optimal, since constant temperature controls must take place, which in turn cause high energy consumption.
Der Erfindung zugrundeliegende Aufgabe The problem underlying the invention
Der Erfindung liegt die Aufgabe zugrunde, einen verbesserter Warmwasserspeicher bereitzustellen, welcher eine konstante Entnahmetemperatur bereitstellt und gleichzeitig energieeffizient betrieben werden kann. The invention has for its object to provide an improved hot water tank, which provides a constant extraction temperature and at the same time can be operated energy efficient.
Erfindungsgemäße Lösung Inventive solution
Die Lösung der gestellten Aufgabe gelingt durch einen Warmwasserspeicher zum Bereitstellen von Warmwasser mit den Merkmalen des Anspruchs 1. Vorteilhafte Aus- und Weiterbildungen, welche einzeln oder in Kombination miteinander eingesetzt werden können, sind Gegenstand der abhängigen Ansprüche. The solution of the problem is achieved by a hot water tank for providing hot water with the features of claim 1. Advantageous training and further developments, which can be used individually or in combination with each other, are the subject of the dependent claims.
Der erfindungsgemäße Warmwasserspeicher zum Bereitstellen von Warmwasser umfasst wenigstens einen Wasserzulauf zum Zuführen von Kaltwasser, einen Wasserablauf zum Abführen von Warmwasser und eine Mischvorrichtung zum Einstellen einer Temperatur des abgeführten Warmwassers. Das Einstellen der Temperatur des abgeführten Warmwassers in der Mischvorrichtung erfolgt durch Zufuhr von Kaltwasser über einen Bypass, welcher den Wasserzulauf mit der Mischvorrichtung verbindet. The hot water storage according to the invention for providing hot water comprises at least one water inlet for supplying cold water, a water outlet for discharging hot water and a mixing device for adjusting a temperature of the discharged hot water. Setting the temperature of the discharged hot water in the mixing device is done by supplying cold water through a bypass, which connects the water inlet with the mixing device.
Die Temperatur des erwärmten Wassers im Warmwasserspeicher kann somit sehr hoch gehalten werden, und folglich kann der Bildung von Legionellen entgegen gewirkt werden. Durch den Bypass bzw. Kaltwasserbypass kann frisches Wasser mit dem heißen Wasser
aus dem Dom des Warmwasserspeichers vermischt werden, um somit eine gewünschte Temperatur an der Entnahmestelle zu erzielen. Während der Entnahme wird stets Wasser mit einer konstanten bzw. vom Nutzer gewünschten Temperatur abgegeben. Die Mischvorrichtung wird entsprechend dem Benutzerwunsch vorprogrammiert und die relativ hohe Wassertemperatur aus dem Dom wird mit Hilfe des Frischwassers aus dem Kaltwasserbypass auf den gewünschten Wert bereitgestellt. Der Dom eines Warmwasserspeichers ist der Bereich in dem das erwärmte Heiß-Wasser üblicherweise entnommen wird. The temperature of the heated water in the hot water tank can thus be kept very high, and consequently the formation of Legionella can be counteracted. Through the bypass or cold water bypass can fresh water with the hot water be mixed from the dome of the hot water tank, so as to achieve a desired temperature at the sampling point. During removal, water is always delivered at a constant or user-specified temperature. The mixing device is pre-programmed according to the user's request and the relatively high water temperature from the dome is provided by the fresh water from the cold water bypass to the desired value. The dome of a hot water tank is the area in which the heated hot water is usually taken.

Ausführliche Beschreibung anhand eines Ausführungsbeispiels Detailed description based on an embodiment
Bei der nachfolgenden Beschreibung der vorliegenden Erfindung bezeichnen gleiche Bezugszeichen gleiche oder vergleichbare Komponenten. In the following description of the present invention, like reference characters designate like or similar components.
Die in der vorstehenden Beschreibung, den Ansprüchen und den Zeichnungen offenbarten Merkmale können sowohl einzeln als auch in beliebiger Kombination für die Verwirklichung der Erfindung in ihren verschiedenen Ausgestaltungen von Bedeutung sein. The features disclosed in the foregoing description, the claims and the drawings may be of importance both individually and in any combination for the realization of the invention in its various forms.
Fig. 1 zeigt einen Warmwasserspeicher 1 gemäß der vorliegenden Erfindung. Der Warmwasserspeicher 1 weist beispielsweise eine Zylinderform auf, in welcher das zu erwärmende Wasser in einem Innenbehälter bzw. Warmwassertank 18 eingeschlossen ist. Der Innenbehälter 18 kann beispielsweise aus metallischem Material bestehen aber andere Materialien sind ebenfalls möglich. Der Innenbehälter 18 kann beispielsweise von einer Isolationsschicht umgeben werden, welche zu einem verbesserten Bereitschaftsenergieverbrauch führen kann. Gemäß dieser Ausführungsform stellt der Warmwasserspeicher eine vertikale Montage dar, jedoch andere Formen der Montage an einer Wand sind auch möglich, z.B. horizontal. Fig. 1 shows a hot water tank 1 according to the present invention. The hot water tank 1 has, for example, a cylindrical shape in which the water to be heated is enclosed in an inner container or hot water tank 18. The inner container 18 may for example consist of metallic material but other materials are also possible. The inner container 18 may for example be surrounded by an insulating layer, which may lead to an improved standby energy consumption. According to this embodiment, the hot water tank represents a vertical mounting, but other forms of mounting on a wall are also possible, e.g. horizontal.
Der Warmwasserspeicher 1 weist einen Zulauf 10 und einen Ablauf 12 auf, aus welchem das erwärmte Wasser entnommen werden kann. Der Zulauf 10 wird an einem Wassernetz angeschlossen, so dass der Warmwasserspeicher Frischwasser zur Erwärmung und Speicherung erhalten kann. Innerhalb des Warmwasserspeichers ist eine Heizeinrichtung 20 angeordnet, welche wiederum von der Versorgungsspannung 21 gespeist werden kann. Die Heizeinrichtung 20 kann verschiedene Ausgestaltungen aufweisen. In der Fig. 2 ist die Heizeinrichtung 20 schematisch dargestellt. Der
Warmwasserspeicher 1 wird im Betrieb mit Frischwasser befüllt, welches anschließend mit Hilfe der Heizeinrichtung 20 erwärmt bzw. erhitzt wird. Durch das Erwärmungsprozess ändert sich die Dichte des Warmwassers 17 innerhalb des Innenbehälters 18 des Warmwasserspeichers 1 , welches dazu führt, dass das erwärmte Wasser 17 nach oben steigt und innerhalb des Innenbehälters 18 bilden sich Bereiche mit Wasser unterschiedlicher Temperatur. In diesem Beispiel werden schematisch zwei Bereiche 18, 19 dargestellt, nämlich der Kaltwasserbereich 19 im unteren Teil des Innenbehälters 18 und der Warmwasserbereich 17 (Dom) oberhalb des Kaltwasserbereiches 19. Es soll klargestellt werden, dass in der Praxis die Schichtgrenze nicht so deutlich wahrnehmbar sind. Die Darstellung der Fig. 1 soll jedoch die prinzipielle inhomogene Wassertemperaturverteilung innerhalb des Innenbehälters 18 des Warmwasserspeichers 1 verdeutlichen. Verursacht werden diese Schichtungen im Wesentlichen beim Zapfen von Warmwasser und dem Zufließen von Kaltwasser. The hot water tank 1 has an inlet 10 and a drain 12, from which the heated water can be removed. The inlet 10 is connected to a water network, so that the hot water tank can receive fresh water for heating and storage. Within the hot water tank, a heater 20 is arranged, which in turn can be fed by the supply voltage 21. The heater 20 may have various configurations. In Fig. 2, the heater 20 is shown schematically. Of the Hot water tank 1 is filled with fresh water during operation, which is then heated or heated by means of the heater 20. By the heating process, the density of the hot water 17 within the inner container 18 of the hot water tank 1, which causes the heated water 17 rises upward and within the inner container 18 forms areas with water of different temperature. In this example, two areas 18, 19 are shown schematically, namely the cold water area 19 in the lower part of the inner container 18 and the hot water area 17 (Dom) above the cold water area 19. It should be clarified that in practice the layer boundary are not so clearly perceptible , The illustration of FIG. 1 is intended to illustrate the principle inhomogeneous water temperature distribution within the inner container 18 of the hot water tank 1. These stratifications are mainly caused by the tapping of hot water and the inflow of cold water.
Die Entnahme des Warmwassers 17 erfolgt im oberen Bereich des lnnenbehältersτ Nach Abnahme von Warmwasser, kann Frischwasser über den Zulauf 10 nachfließen und die Heizeinrichtung 20, kann erneut das kalte Wasser erwärmen. The removal of the hot water 17 takes place in the upper region of the inner container. After removal of hot water, fresh water can flow in via the inlet 10 and the heating device 20 can again heat the cold water.
Der Wasserablauf 12 wird gemäß der vorliegenden Erfindung mit einer Mischvorrichtung 14 versehen, welche es einem Benutzer erlaubt die gewünschte Warmwassertemperatur einzustellen, welche in der Praxis sich stark von der Domtemperatur unterscheidet. Innerhalb des Warmwasserspeichers 1 sollte bevorzugt stets eine Temperatur oberhalb 60° eingestellt sein, um die Bildung von Bakterien, z.B. Legionellen zu unterdrücken. Bei einer direkten Abnahme des Warmwassers aus dem Dom mit dieser hohen Domtemperatur, würde sich ein Benutzer verbrühen können. Erfindungsgemäß weist der Warmwasserspeicher 1 einen Bypass bzw. Kaltwasserbypass 16 auf, welcher den Kaltwasserzulauf 10 mit der Mischvorrichtung 14 verbindet. In der Mischvorrichtung 14 kann somit die gewünschte Temperatur für den Verbraucher eingestellt werden. Die Domtemperatur kann weiterhin auf einem hohen Wert gehalten werden und durch den integrierten Einbau des Kaltwasserbypasses 16 im Warmwasserspeicher, kann die Leitungslänge der Heiß-Wasserleitunge« verkürzt werden. Somit können die Wärmeverluste weiter minimiert werden. Durch die niedrigere Warmwassertemperatur kann bei gleicher zur Verfügung stehender Warmwassermenge eine deutliche Reduzierung der Wärmeverluste in der Warmwasserleitung erreicht werden.
Die Mischvorrichtung 14 kann beispielsweise als Dreiwegeventil implementiert werden, und der Benutzer stellt die Wunschtemperatur einfach ein. Ferner können Temperatursensoren 22 innerhalb der Mischvorrichtung 16 oder in den Wasserleitungen im Bereich der Mischvorrichtung eingebaut werden. Diese Temperatursensoren 22, welche in der Fig. 1 schematisch dargestellt sind liefern genaue Temperaturwerte ak, welche für eine genaue und sichere Regelung der Temperatur innerhalb der Mischvorrichtung 14 verwendet werden können. Die Temperatursensoren 22 können ferner mit einer Steuereinrichtung verbunden werden, welche elektronisch den Betrieb des Warmwasserspeichers steuern kann. Dadurch, dass die Mischvorrichtung den genauen Wert der Wassertemperatur innerhalb des Kaltwasserbypasses 16 erfasst, kann eine genaue und/oder schnelle Regelung erfolgen. The water drain 12 is provided according to the present invention with a mixing device 14, which allows a user to set the desired hot water temperature, which in practice differs greatly from the dome temperature. Within the hot water tank 1, a temperature above 60 ° should preferably always be set in order to suppress the formation of bacteria, eg Legionella. With a direct decrease of hot water from the dome with this high dome temperature, a user would be able to scald himself. According to the invention, the hot water tank 1 has a bypass or cold water bypass 16, which connects the cold water inlet 10 with the mixing device 14. In the mixing device 14 thus the desired temperature for the consumer can be adjusted. The dome temperature can still be maintained at a high level and by the integrated installation of the cold water bypass 16 in the hot water tank, the length of the hot water pipes can be shortened. Thus, the heat losses can be further minimized. Due to the lower hot water temperature, a significant reduction in heat losses in the hot water pipe can be achieved with the same amount of hot water available. For example, the mixing device 14 may be implemented as a three-way valve, and the user simply sets the desired temperature. Furthermore, temperature sensors 22 can be installed inside the mixing device 16 or in the water lines in the area of the mixing device. These temperature sensors 22, which are shown schematically in FIG. 1, provide accurate temperature values ak, which can be used for accurate and reliable control of the temperature within the mixing device 14. The temperature sensors 22 may further be connected to a control device which can electronically control the operation of the hot water tank. Characterized in that the mixing device detects the exact value of the water temperature within the cold water bypass 16, an accurate and / or fast control can take place.
Durch die Verwendung mehrerer Temperatursensoren 22, die an unterschiedlichen Stellen des Warmwasserspeichers platziert werden können, wird ein genaues und zuverlässiges Zumischen von Kaltwasser aus dem Kaltwasserbypass 16 in der geregelten Mischvorrichtung 14 erreicht. So kann, falls die Temperatur des Kaltwassers aus dem Bypass 16 stark variiert eine schnelle Regelung bzw. Steuerung der Auslauftemperatur im Wasserablauf 12 bereitgestellt werden. Die Domtemperatur des Warmwassers 17 kann auf einem relativ hohen Wert gehalten werden. Die Zumischung von Kaltwasser mittels des Bypasses 16 wird unmittelbar am Warmwasserspeicher 1 bereitgestellt, um die Wärmeverluste aus der Warmwasserleitung zu minimieren, was zu einer deutlichen Energieeinsparung führt. Durch die geregelte Mischvorrichtung 14 kann eine konstante Temperatur an der Entnahmestelle garantiert werden, ohne dass ein Benutzer die Austrittstemperatur ständig manuell nachregeln muss. By using a plurality of temperature sensors 22, which can be placed at different locations of the hot water tank, an accurate and reliable mixing of cold water from the cold water bypass 16 in the controlled mixing device 14 is achieved. Thus, if the temperature of the cold water from the bypass 16 varies greatly, rapid control of the outlet temperature in the water drain 12 can be provided. The dome temperature of the hot water 17 can be maintained at a relatively high level. The addition of cold water by means of the bypass 16 is provided directly to the hot water tank 1 in order to minimize the heat losses from the hot water pipe, resulting in a significant energy savings. By the controlled mixing device 14, a constant temperature at the extraction point can be guaranteed without a user must readjust the outlet temperature constantly manually.
Gemäß einer Ausführungsform der Erfindung ist der Bypass 16 beispielsweise als Leitung oder Wasserleitung ausgeführt, die den Zulauf 10 mit der Mischvorrichtung direkt verbindet. Es ist jedoch vorstellbar, dass der Bypass 16 aus einer Vielzahl von Leitungen gebildet ist, so dass beispielsweise die Menge an Kaltwasser, das die Mischvorrichtung erreicht anhand der Anzahl von Leitungen einstellbar ist. Auch denkbar ist, dass der
Bypass 16 als elastisches bzw. biegeelastisches Schlauchstück ausgeführt ist, um beispielsweise ein Anbringen in einem Gehäuse bzw. Außengehäuse 28 zu ermöglichen. Das Außengehäuse kann um den Warmwasserspeicher 1 ausgebildet werden, um ein ansprechendes Äußeres der Gesamtvorrichtung, d.h. des Warmwasserspeichers im montierten Zustand, zu gewährleisten. According to one embodiment of the invention, the bypass 16 is designed, for example, as a line or water pipe, which connects the inlet 10 directly to the mixing device. However, it is conceivable that the bypass 16 is formed of a plurality of lines, so that, for example, the amount of cold water reaching the mixing device is adjustable based on the number of lines. It is also conceivable that the Bypass 16 is designed as an elastic or flexurally elastic hose piece, for example, to allow attachment in a housing or outer housing 28. The outer housing can be formed around the hot water tank 1, to ensure a pleasing appearance of the entire device, ie the hot water tank in the assembled state.
Fig. 2 zeigt eine schematische Ansicht eines Warmwasserspeichers gemäß der vorliegenden Erfindung. Der Warmwasserspeicher 1 weist ein Außengehäuse 28 auf, welches alle Komponenten umschließt und der Gesamtvorrichtung ein ansprechendes Äußeres verschafft. Das Außengehäuse 28 umschließt gemäß einer bevorzugten Ausführungsform den Kaltwasserbypass 16 und die Mischvorrichtung 14, so dass eine Integralbauweise des Warmwasserspeichers bereitgestellt ist. Somit ist die Kaltwasserzuführung mit Hilfe des Bypasses 16 von außen nicht sichtbar. Fig. 2 shows a schematic view of a hot water tank according to the present invention. The hot water tank 1 has an outer housing 28, which encloses all components and provides the overall device an attractive appearance. The outer housing 28 encloses according to a preferred embodiment, the cold water bypass 16 and the mixing device 14, so that an integral construction of the hot water tank is provided. Thus, the cold water supply by means of the bypass 16 is not visible from the outside.
Innerhalb des Innenbehälters 18 bzw. des Warmwassertanks ist eine Heizeinrichtung 20 angeordnet, welche die im Innenbehälter eingeschlossene Wassermenge erhitzen kann.Within the inner container 18 and the hot water tank, a heater 20 is arranged, which can heat the enclosed in the inner container amount of water.
Die Heizeinrichtung 20 wird über eine geeignete Elektronik bzw. einen Temperaturregler aus der Netzspannungseinrichtung 21 gespeist, welche wiederum Energie aus einem öffentlichen Stromnetz erhalten kann. Die Form der Heizeinrichtung 20 ist nur beispielhaft gezeigt, da andere Formen und Montagestellen innerhalb des Innenbehälters 18 realisierbar sind. The heater 20 is powered by a suitable electronics or a temperature controller from the mains voltage device 21, which in turn can receive energy from a public power grid. The shape of the heater 20 is shown only as an example, since other shapes and mounting locations within the inner container 18 can be realized.
Der Warmwasserspeicher umfasst ferner eine Steuereinrichtung 25, welche mit der Mischvorrichtung 14 verbunden ist. Somit kann die Mischvorrichtung 14 gesteuert werden. Die Steuereinrichtung 25 kann beispielsweise eine Temperaturanzeige und ein Steuermittel aufweisen, an welchem eine gewünschte Temperatur des Warmwassers eingestellt werden kann. Die Temperaturanzeige und/oder das Steuermittel können auch separat von der Steuereinrichtung 25 implementiert werden. Die Anzeige kann eingerichtet sein die Temperatur des abgezapften Warmwassers am Ablauf 12 anzuzeigen, welche von einem geeigneten Temperatursensor 22 erfasst werden kann. Ferner kann beispielsweise auch die Kaltwassertemperatur des hineinströmenden Wassers an Zulauf 10 erfasst und angezeigt werden. Ein Verbraucher kann demnach eine gewünschte Temperatur mittels der Steuereinrichtung 25, d.h. beispielsweise mit Hilfe des Steuermittels, einstellen und falls diese Temperatur niedriger als die
Warmwassertemperatur innerhalb des Warmwasserbehälters 18 ist, wird entsprechend Kaltwasser aus dem Bypass 16 beigemischt. Da die Temperatur des Kaltwassers im Zulauf 10 ebenfalls bekannt ist, kann die Mischvorrichtung entsprechend die gewünschte Wassertemperatur schnell einstellen, so dass das Warmwasser im Ablauf 12 ohne wahrnehmbare Zeitverzögerung, bedingt durch Regelvorgänge in der Mischeinrichtung 14, diese Temperatur aufweist. Temperaturfühler oder Temperatursensoren 22 können ebenfalls auch innerhalb des Warmwasserbehälters 18 angeordnet werden, um somit möglichst viele Messdaten der Steuereinrichtung 25 bereitstellen zu können. Demnach kann die Regelgeschwindigkeit der Mischvorrichtung verbessert werden. Die Erfindung kann auch bei Wandspeichern, Kleinspeichern als Über- oder Untertischgerät oder Standspeichern angewendet werden, welche zur Erzeugung von Warmwasser für Verbraucher einsetzbar sind. Diese Geräte können beispielsweise im Bad oder Küche Einsatz finden, jedoch auch andere Montagestellen oder Installationsorte sind vorstellbar.
The hot water tank further comprises a control device 25, which is connected to the mixing device 14. Thus, the mixing device 14 can be controlled. The control device 25 may, for example, have a temperature display and a control means, on which a desired temperature of the hot water can be adjusted. The temperature display and / or the control means may also be implemented separately from the controller 25. The display may be configured to indicate the temperature of the tapped hot water at the drain 12, which may be detected by a suitable temperature sensor 22. Furthermore, for example, the cold water temperature of the inflowing water can be detected at inlet 10 and displayed. A consumer can therefore set a desired temperature by means of the control device 25, ie, for example, by means of the control means, and if this temperature is lower than that Hot water temperature is within the hot water tank 18, according to cold water from the bypass 16 is mixed. Since the temperature of the cold water in the inlet 10 is also known, the mixing device can adjust the desired water temperature accordingly quickly, so that the hot water in the drain 12 without noticeable time delay due to control operations in the mixing device 14, this temperature. Temperature sensor or temperature sensors 22 can also be arranged within the hot water tank 18, so as to provide as many measurement data of the control device 25 can. Accordingly, the control speed of the mixing apparatus can be improved. The invention can also be applied to wall storage systems, small storage systems as over- or under-counter equipment or stand storage tanks, which can be used to generate hot water for consumers. These devices can be used, for example, in the bathroom or kitchen, but other mounting sites or installation sites are conceivable.
