Cetetherm Pipe Sizing powered by Hysopt will provide more accurate calculations, compliant with the relevant industry standards. A detailed pipe sizing cuts oversizing and thereby contributes to more efficient heat networks.
The physical calculation model ensures the software ‘knows’ what has been designed and can trace hydraulic concept faults and make them visible to the designer.
DIVERSITY FOR DOMESTIC HOT WATER
Hysopt supports diversity calculation based on the Danish DS439, the Swedish DHA F:101, the German DIN 1988-300 and the French COSTIC standard.
DIVERSITY FOR CENTRAL HEATING
Cetetherm Pipe Sizing also supports diversity calculation for central heating. This diversity curve can be tweaked to meet the required standard.
HEAT EXCHANGER CALCULATION
The Cetetherm Pipe Sizing calculates the exact return temperature and resulting flow rate through heat exchangers for any given design condition, using the heat transfer coefficient of the heat exchanger. Cetetherm can use these detailed calculations to show the supremacy of their products.
To avoid oversizing of pipework, Hysopt will aggregate all the heat loads in the network correctly, based on the chosen diversity standards. In each pipe, the supply for domestic hot water, for heating prioritised by DHW (e.g. when HIU’s are applied), and the supply for heating not prioritised by DHW are aggregated and weighted based on diversity factors.
As a result, overestimation of the heat loads and the flow rates are prevented. Both Cetetherm and Hysopt stress out the importance of calculating the return temperatures and flow rates.
The Cetetherm Pipe Sizing can deliver the following outputs:
- P&ID schematic (risers and laterals), detailing:
- Peak loads
- Temperature regimes
- Flow rates
- Pipe sizes and lengths
- Export of component list with:
- Pipe schedule
- HIU schedule
This is a great kick-start for developing an efficient heat network.

HVAC digital twin software
With dynamic simulation, the Hysopt software can predict the dynamic behaviour of this installation such that the performance of a system becomes predictable and measurable, even before it is being installed. This allows the designer of heating and cooling installations to optimise designs for their client.
