A commissioning module 100 for a fluid distribution system comprises a plurality of fluid distribution valves 7, 8, 9, 10, isolating valves 2, 16, 18, fluid flow-regulating valves 25, 26, 27, 28, flow rate measuring means and at least one drain-off cock 6. The module 100 is operable to establish and to maintain set fluid-flow conditions in the fluid- distribution system. In operation the fluid distribution valves 7, 8, 9, 10 supply a working fluid to heat exchangers via supply lines 11, 12, 13, 14 and the working fluid returns from the heat exchangers by way of fluid exhaust lines 31, 32, 33, 34. The module 100 permits the filling and pressure testing of a fluid distribution system to which it belongs by use of a test point 15 for monitoring the fluid supply pressure and a test point 20 for monitoring the fluid exhaust pressure. The fluid flow rates throughout the fluid distribution system may be balanced in order to ensure that all parts of the system receive an adequate proportion of the total flow from a supply by the use of the regulating valves 25, 26, 27, 28. The module 100 may itself be flushed and cleaned by opening the isolating valve 16. In an alternative embodiment a commissioning module 100 includes a plurality of heat exchangers connected to the module 100.
