As described in the CIBSE CP1 Heat networks code of practice.
| A | Primary pipework (or primary heat network). |
| B | Secondary pipework (or secondary heat network). |
| C | Tertiary pipework (or tertiary heat network, heating and DHWS internal to the apartment and separated from the primary network). |
| D | Sub Station |
The Substation separates the buildings from the district heating pipe network or used as a pressure break in very high building to prevent extreme pressure differentials.
Where the temperatures and pressures of the building’s heating systems differ from those of the district heating network, it is usually necessary to utilise a Substation. A Substation consists of a plate heat exchanger which creates pressure break between the district network and consumer system.
The district heating supplier will provide information on the actual minimum and maximum differential pressures, as measured at the service connection valves. This data should be used for determining the sizes and capacities of control valves and heat exchangers.
