<p>The method involves supplying primary side heat flow (16) to a heat exchanger (10) for heating a secondary side of first heat flow (50). Second heat flow (52) is heated under the application of primary side reverse flow (18) of the heat exchanger. Third heat flow (38) is heated under the application of the second heat flow, and is separated from the second heat flow, where the reverse flow of the heat exchanger has high temperature. The reverse flow is mixed with the primary side heat flow before heating the second heat flow in a predetermined mixing ratio. An independent claim is also included for a long-distance heating-or local-heating transmission station comprising a return pipe.</p> |
