<p>The storage (10) has a container (12) comprising a revision opening (16) that is closed by a closing stopper (18), and a connection opening (20) arranged in an upper area. A heat source is arranged in the connection opening for discharging warm water. An electrical resistor heating element is inserted into the revision opening and attached at a photovoltaic-system via an electrical line for power supply, where the electrical line is attached at the photovoltaic-system. A heat exchanger element (26) i.e. heat tube chain, is attached at a heating body.</p> |
