Ein Ausführungsbeispiel der erfindungsgemäßen Druckeinrichtung sieht weiter vor, dass der Druckminderer mit dem Druckerhöher gekoppelt ist, um den Druck des zugeführten Wassers auf das erwärmte, druckreduzierte Wasser zu übertragen.

Mit den erfindungsgemäßen Verfahren, der erfindungsgemäßen Druckeinrichtung und der Brauchwasserversorgungseinrichtung werden insbesondere die folgenden Vorteile realisiert:
- Durch die Druckreduzierung vor der Erwärmung und vor dem Speichern, insbesondere vor Zufuhr zu einem Brauchwasserspeicher ist es möglich, den Brauchwasserspeicher drucklos auszulegen, sodass dieser aus einem kostengünstigeren Material wie beispielsweise Kunststoff herstellbar ist. Auf diese Weise ist der Aufwand zur Herstellung des Brauchwasserspeichers reduziert.
- By reducing the pressure before heating and before storing, especially before feeding to a hot water tank, it is possible to design the hot water tank without pressure, so that this from a cheaper material such For example, plastic can be produced. In this way, the cost of producing the hot water tank is reduced.
Mittels der Druckübertragung wird die Druckenergie vom Kaltwasser, welches sonst unter Druck in den Brauchwasserspeicher strömen würde, auf das heiße Wasser, welches zur Zapfstelle gelangen soll, übertragen. Aufgrund dessen, dass der Brauchwasserspeicher keinen erhöhten Druckverhältnissen durch die Druckreduzierung standhalten muss, kann dieser in jeder geometrischen Bauform (quadratisch, dreieckig, usw....) ausgeführt werden. Die Speicherwandungen müssen nicht aus z. B. druckfesten Stahl, sondern können aus jedem trinkwassergeeigneten Material ausgeführt werden. Die Druckübertragung ermöglicht einfachste Konstruktionen, insbesondere bei Speichern mit sehr großem Volumen. Denn bei Speichern mit sehr großem Volumen stellt der hohe Wasserdruck ein besonderes Problem dar, aufgrund der hohen Belastung der Speicherwände. Die erfindungsgemäße Lösung ermöglicht die Nutzung eines beliebigen Behälters als Brauchwasserspeicher, sofern der Behälter aus trinkwassergeeignetem Material besteht. Aufgrund dessen, dass die Speicherwände nicht aus Stahl gefertigt werden müssen, kann der Brauchwasserspeicher kostengünstiger und leichter produziert werden.By means of the pressure transmission, the pressure energy from the cold water, which would otherwise flow under pressure into the process water storage tank, is transferred to the hot water which is to reach the tap. Due to the fact that the DHW cylinder does not have to withstand increased pressure conditions due to pressure reduction, it can be designed in any geometric design (square, triangular, etc.). The storage walls do not need z. As pressure-resistant steel, but can be performed from any drinking water suitable material. The pressure transmission allows the simplest designs, especially for very large volume storage. Because when storing with very large volume, the high water pressure is a particular problem, due to the high load on the storage walls. The solution according to the invention allows the use of any container as a hot water tank, if the container is made of drinking water suitable material. Due to the fact that the storage walls do not have to be made of steel, the water storage tank can be produced more cheaply and easily.
