Dabei ist die Wärmequelle im Brauchwasserbehälter untergebracht und von den ebenfalls im Brauchwasserbehälter untergebrachten thermoelektrischen oder Seebeck-Einrichtungen umschlossen. Die erzeugte elektrische Energie wird zur elektrischen Speisung einer Pumpe im Kreislauf des Brauchwassers verwendet.A hot water storage tank operating on a similar principle is described in WO 97 / 35153. The heat source is housed in the domestic water tank and the thermoelectric ones, which are also housed in the process water tank or Seebeck facilities. The generated electrical Energy is used to electrically supply a pump in the circuit of the Domestic water used.

Bei dieser Ausgestaltung ist die Wärme- und Stromerzeugung in den Warmwasserspeicher optimal integriert, der damit eine einfache selbständige Einheit bildet. Mit der Betriebszeit des Energie-Wandlers kann auch die erzeugte, elektrische Energie erhöht werden, wobei die anfallende Wärme stets direkt dem zu erwärmenden Brauchwasser im Brauchwasserbehälter zugeführt wird. Die erzeugte elektrische Energie kann nicht nur zur Versorgung der elektrischen Einrichtungen des Warmwasserspeichers, sondern auch zur Deckung einer elektrischen Grundlast oder dgl. in einem Haushalt dienen.In this embodiment, the heat and electricity is generated in the hot water tank optimally integrated, which thus forms a simple, independent unit. With the operating time of the energy converter, the generated electrical can Energy can be increased, the heat generated always directly to be heated Process water is supplied in the process water tank. The generated Electrical energy can not only be used to supply electrical equipment of the hot water tank, but also to cover an electrical base load or the like. Serve in a household.

Nach einer bevorzugten Ausgestaltung kann der Aufbau des Warmwasserspeichers so vorgenommen sein, dass der Energie-Wandler in eine Kammer im Bodenbereich des Brauchwasserbehälters ragt und dass die Kammer mit einem durch den Brauchwasserbehälter vertikal durchgeführten Wärmeübertrager in Verbindung steht, der außerhalb des Deckenbereiches des Brauchwasserbehälters in einen Abgasauslass mündet.According to a preferred embodiment, the construction of the hot water tank be made so that the energy converter into a chamber in the floor area of the domestic water tank protrudes and that the chamber with a through the hot water tank vertically performed heat exchanger in Connection is made outside the ceiling area of the domestic water tank opens into an exhaust outlet.

Dabei kann der Wärmeübergang von dem Wärmeübertrager zum Brauchwasser im Brauchwasserbehälter dadurch verbessert werden, dass der Wärmeübertrager als mit Außenrippen versehenes Rohr ausgebildet ist.The heat transfer from the heat exchanger to the process water can in the domestic water tank can be improved in that the heat exchanger is designed as a tube provided with outer fins.

Eine vorteilhafte Konstruktion für den Energie-Wandler ergibt sich dadurch, dass im Falle eines thermisch-elektrischen Energie-Wandlers ein Brenner zur Verbrennung eines Brennstoffgemisches integriert ist.An advantageous construction for the energy converter results from the fact that in the case of a thermal-electrical energy converter, a burner for combustion a fuel mixture is integrated.

Innerhalb eines Speichergehäuses 15 teilt ein Brauchwasserbehälter 10 einen Aufnahmeraum 11 für Brauchwasser ab. Das Brauchwasser wird über einen Zulauf 12 dem Brauchwasserbehälter 10 zugeführt und über einen Ablauf 13 entnommen. In den Bodenbereich des Brauchwasserbehälters 10, jedoch noch innerhalb des Speicherbehälters 15, ragt eine Kammer 14, die einen Teil des Energie-Wandlers, insbesondere den bevorzugt Wärme abgebenden Teil, aufnimmt. Der Energie-Wandler 20 integriert im Falle eines thermisch-elektrischen Energie-Wandlers alle Teile zum Vermischen und Verbrennen des Brennstoffes, insbesondere also auch den Brenner, in einer Baueinheit, die in dem Speichergehäuse 15 unterhalb des Brauchwasserbehälters 10 eingebaut ist.A domestic water tank 10 divides one within a storage housing 15 Recording room 11 for domestic water. The process water is fed through an inlet 12 fed to the domestic water tank 10 and removed via an outlet 13.

Über dem Deckenbereich des Brauchwasserbehälters 10 mündet der Wärmeübertrager 16 in einem Abgasauslass 17 für das Abgas 18. Der Baueinheit des Energie-Wandlers 20 wird der umzusetzende Brennstoff 21 zugeführt und die erzeugte elektrische Energie 22 wird nicht nur zur Versorgung eigener elektrischer Einrichtungen des Warmwasserspeichers, sondern auch externen Verbrauchern und/oder dem öffentlichen Stromnetz zugeführt.A tubular heat exchanger 16, which acts as a tube, extends from the chamber 14 formed with outer ribs and vertically through the hot water tank 10 is led.
