Aus der polnischen Beschreibung des Gebrauchsmusters Nr. Ru 55 852 ist ein Brauchwasservorwärmer bekannt, der mit Heizwasser aus den Systemen in den mit Gas oder Heizöl beheizten Kesselhäusern gespeist wird und mit einem aus einigen Plattenwärmetauscher bestehenden Plattenwärmetauschersatz ausgerüstet ist. Der Wärmetauschersatz ist durch Anschlüsse in den Warmwasserauslaufkollektor eingebaut und ist mit einem Stabilisator verbunden, der wiederum durch einen Stutzen und eine Umlaufpumpe mit einer Leitung für äußere Zirkulation sowie durch einen Stutzen, einen Rückschlagventil und eine Pumpe für innern Umlauf mit dem Kaltwasserkollektor verbunden ist. Der aus einigen Plattenwärmetauscher bestehende Wärmetauschersatz ist an die Heizwasserspeiseleitung angeschlossen.
(Weitere Brauchwasservorwärnier sind aus den Patentanmeldungen DE 10036452A , DE 3836523A und WO 9529127A bekannt.)From the Polish description of the utility model no. Ru 55 852 a domestic water heater is known, which is fed with heating water from the systems in the boiler or heating oil heated boiler houses and is equipped with a plate heat exchanger consisting of some plate heat exchange. The heat exchange kit is installed in the hot water outlet collector through connections and is connected to a stabilizer which in turn is connected to the cold water collector by a spigot and circulating pump with an external circulation line and a spigot, check valve and internal recirculation pump. The existing of some plate heat exchanger heat exchange kit is connected to the Heizwasserspeiseleitung.
(Further hot water preheaters are from the patent applications DE 10036452A . DE 3836523A and WO 9529127A known.)

Auf dem Boden des gleichzeitigen Stands der Technik entstand die Aufgabe, eine Konstruktion des Brauchwasservorwärmers mit einer Schutzmaßnahme gegen Entstehung von Stämmen der Legionärskrankheitsbakterien zu schaffen sowie entsprechende Lösungen für Beseitigung der Temperaturaufschichtung des Warmwassers und für Erhalten der Wassertemperatur im Stabilisatorbehälter von +60°C auf der ganzen Behälterhöhe einzuführen.
Der ausarbeitete Vorwärmer soll darüber hinaus der Zusammenarbeit mit den Kondensationskesseln vom hohen technischen Wirkungsgrad angepasst werden.On the basis of the contemporary state of the art the task arose to create a construction of the hot water heater with a protective measure against formation of strains of Legionnaires' disease bacteria and solutions for eliminating the temperature stratification of the hot water and for maintaining the water temperature in the stabilizer tank of + 60 ° C on the to introduce the entire container height.
The elaborated preheater will also be adapted to the cooperation with the condensing boilers of high technical efficiency.

Der Brauchwasservorwärmer, der dem Gebrauchsmuster gemäß einen Wärmetauschersatz enthält, der aus einigen in den Kaltwasserkollektor und in den Warmwasserausgangskollektor eingebauten sowie an die Heizwasserspeiseleitung angeschlossenen Plattenwärmetauschem zusammengesetzt ist, charakterisiert sich dadurch, dass er eine Mischeinheit besitzt, die ein thermostatisches Ventil, einen Ausgangskollektor, ein Kontrollthermometer für Überwachung des warmen Brauchwassers mit der Temperatur von +60°C und ein Thermometer für Zirkulation des warmen Brauchwassers mit der Temperatur von +55°C enthält. Die Mischeinheit ist durch einen Auslaufstutzen und eine Leitung mit Wasser mit erhöhter Temperatur mit dem Stabilisator verbunden. Der Stabilisator ist durch den Plattenwärmetauschersatz mit einem Sicherheitsventil und mit einem Ausdehnungsgefäß von der Kaltwasserseite hydraulisch verbunden.The domestic water heater, which according to the utility model contains a heat exchange set composed of some plate heat exchangers installed in the cold water collector and in the hot water outlet collector and connected to the heating water supply pipe, is characterized by having a mixing unit comprising a thermostatic valve, an outlet collector Control thermometer for monitoring of the warm Hot water with a temperature of + 60 ° C and a thermometer for circulation of hot domestic water with a temperature of + 55 ° C. The mixing unit is connected to the stabilizer through a spout and a conduit of elevated temperature water. The stabilizer is hydraulically connected through the plate heat exchange kit with a safety valve and with an expansion vessel from the cold water side.

Der diesem Gebrauchsmuster gemäß ausgeführte Vorwärmer enthält einige Konstruktionslösungen sowie technologische Lösungen, die vor Entstehung der Bakterienflora, und besonders vor Entstehung von Stämme der Legionärskrankheitsbakterien schützen, deren intensive Entwicklung in Temperaturen von 20°C bis 55°C erfolgt.
Die eingesetzte Mischeinheit mit einem thermostatischen Mischventil ermöglicht Erhaltung im Stabilisator der erhöhten Temperatur von +70°C sowie nach Vermischen erlaubt Zuführung in die Abnahmeanlage des Wassers mit der erforderlichen Temperatur von +60°C.
Weil bei Anlagenausführung ausschließlich nichtrostender Stahl eingesetzt wird, ist die Ablagerung von Kesselstein und Sedimenten mit Legionärskrankheitsbakterien begrenzt sowie ist periodische Erhöhung der Warmwassertemperatur bis zum +80÷90°C und damit vollständige Liquidation der Legionärskrankheitsbakterien in der Vorwärmeranlage möglich.
Der Vorwärmer ist auch völlig der Zusammenarbeit mit den Kondensationskesseln vom hohen technischen Wirkungsgrad angepasst. Das garantiert sehr günstige Abkühlung des Heizwassers um ca. +35°C, weil die Voraussetzung für Kondensationsentstehung in den Kondensationskesseln des Gas- und Ölkesselhauses die ständige Erhaltung der Rücklauftemperatur unterhalb von +57°C ist. Erzielung solcher Temperaturen in den bisher angewandten, mit Rohrheizschlangen ausgerüsteten Kapazitäts- und Durchlaufvorwärmem ist erschwert und gewährleistet die völlige Kondensationsbedingungen nicht.The preheater according to this utility model contains some design solutions and technological solutions that protect against the formation of bacterial flora, and especially against the emergence of strains of Legionnaires' disease bacteria whose intensive development takes place in temperatures of 20 ° C to 55 ° C.
The mixing unit used with a thermostatic mixing valve allows preservation in the stabilizer of the elevated temperature of + 70 ° C and after mixing allows feeding into the acceptance system of the water with the required temperature of + 60 ° C.
Because only stainless steel is used in plant design, deposits of sediment and limestone sediments are limited, as well as a periodic increase of hot water temperature up to + 80 ÷ 90 ° C and complete elimination of legionnaires' disease bacteria in the preheater.
The preheater is also completely adapted to the cooperation with condensing boilers of high technical efficiency. This guarantees very favorable cooling of the heating water by approx. + 35 ° C, because the prerequisite for condensation formation in the condensing boilers of the gas and oil boiler house is the constant maintenance of the return temperature below + 57 ° C. Achieving such temperatures in the previously used, equipped with tubular heating capacity and Durchlaufvorwärmem is difficult and does not guarantee the complete condensation conditions.
