In the apparatus for heat transfer with a liquid heat carrier, at least one flat heat exchanger (1) to receive or give up heat, a duct system with a circulating pump (3), a heat exchanger (2), and a pressure regulating device (4) are connected together such that the circulating pump (3) is installed behind the flat heat exchanger (1), and the apparatus is closed. In a preferred embodiment, the apparatus is permanently and completely under reduced pressure, and the circulating pump (3) is installed in front of, and the pressure regulating device (4) behind, the heat exchanger (2). <IMAGE>
