Abstract

The invention relates to a method for line pressure monitoring, in particular for detecting leaks, in a bidirectionally used line section (40a) of a connection line unit (40) in an energy system (10), in particular in a domestic energy system, as well as an energy system (10) of this type, wherein a first energy source unit (21) and a first energy sink unit (22) are positioned on the first side (43) of the bidirectional line section (40a), and wherein a second energy source unit (31) and a second energy sink unit (32) are positioned on the second side (44) of the bidirectional line section (40a). In order to provide a secure monitoring of a bidirectional line, according to the invention, using two pressure measuring devices (50, 51) positioned spatially separate from one another in the bidirectional line section (40a), a first pressure (P1) and a second pressure (P2) present at the locations of the pressure measuring devices (50, 51) are detected, and, in particular in a control device (60) of the energy system (10), a monitoring of the line pressure in the bidirectional line section (40a) is carried out by means of an evaluation of the pressures (P1, P2) detected by the pressure measuring devices (50, 51), wherein the detected pressures (P1, P2) are placed in relation to one another in different ways.
