A heating and cooling system for a building consists of a component (1), esp. a concrete component, which contains a pipework system that circulates a heating or cooling medium. The pipe system has additional elements (4) that are in direct contact with room air. The pipe system has at least two branch points, and at least one of the branch members (3) is surrounded by a mantle made of e.g. polystyrene. |
