<p>The device has a heat exchanger (2) arranged upstream at an exhaust gas path of another heat exchanger (3). The former heat exchanger is flown through fluid flow, and the latter heat exchanger is flown through another fluid flow. A secondary heat exchanger (4) transfers heat from one of the fluid flows to the other fluid flow. The latter heat exchanger is connected with a stratified storage (5) in a circuit (6). The stratified storage is connected with a cold water supply line (15) at a lower region and connected with an inlet of the latter heat exchanger.</p> |
