Commissioning problems often start before anyone reaches site.
Pumps are selected in one tool. Valves are sized in another. Hydraulic calculations sit in spreadsheets. Presets are added later from separate assumptions.
The result is fragmented data, incorrect settings and unnecessary troubleshooting.
Hysopt Calculator connects these steps through one physics-based hydronic system model.
Calculate the complete hydraulic system
Reliable commissioning starts with a correct system calculation.
Hysopt Calculator calculates flows, pressure losses, pipe sizes and component requirements across the full hydronic network.
Why it matters: Commissioning values are based on the complete system, not isolated components.

Select components in context
Standalone selection tools often assess one valve or pump at one duty point.
Hysopt Calculator connects component selection to:
- system flow rates
- pressure conditions
- pipework
- part-load operation
- connected components
Why it matters: Equipment is selected for how it will operate in the real system.
Size pumps from system demand
Pump duties should reflect the full network.
Hysopt Calculator derives pump requirements from pipe losses, components and intended operating conditions.
Why it matters: Better sizing, less unnecessary margin and lower pumping-energy risk.
Validate valve performance
Valve sizing depends on the pressure available across the complete system.
A valve may look suitable in isolation but perform poorly once installed.
Hysopt Calculator helps teams assess valve selection, pressure conditions and expected control behaviour.
Why it matters: Better authority, more stable control and fewer comfort complaints.
Analyse partial-load operation
Hydronic systems rarely operate continuously at peak load.
Partial-load analysis shows how components behave as demand changes.
Why it matters: Pumps and valves are checked for real operation, not one static design condition.
Generate reliable commissioning presets
Pump and valve presets are derived from the validated hydronic model.
They remain connected to:
- design flows
- pressure requirements
- component performance
- system operating conditions
Why it matters: Site teams begin with settings that match the intended design.
Keep design changes connected
Loads change. Equipment changes. Pipework changes.
In disconnected workflows, every revision requires manual updates across calculations, schedules and commissioning documents.
With Hysopt Calculator, connected parameters can be recalculated from the updated model.
Why it matters: Fewer outdated values and faster project changes.
Deliver HVAC projects with greater confidence ›
Create commissioning-ready outputs
Site teams need clear information, not another calculation file.
Hysopt Calculator can generate:
- bills of materials
- pipe-sizing data
- pump settings
- valve presets
- component schedules
- commissioning-ready documents
Why it matters: Less time searching through drawings, spreadsheets and supplier files.
Reduce first-start problems
Incorrect sizing and settings can cause:
- insufficient flow
- excessive pumping
- unstable temperatures
- control problems
- comfort complaints
- repeated site adjustments
Connected HVAC commissioning software helps prevent these issues before handover.
Why it matters: Faster commissioning with less on-site troubleshooting.
Create a baseline for recommissioning
System performance can drift after handover.
Settings change. Components are replaced. Operating conditions evolve.
The validated model provides a reference baseline for later checks and recommissioning.
Why it matters: Teams can restore intended performance instead of starting again.

What HVAC commissioning software should provide
Effective HVAC commissioning software should help teams:
- calculate the complete hydraulic system
- size pipes consistently
- select pumps and valves
- validate partial-load behaviour
- generate reliable presets
- update settings after design changes
- create clear site documents
- maintain a performance baseline
The goal is not only to commission equipment.
It is to commission the complete system as designed.
Connect hydraulic design to commissioning
Hydraulic system calculation, component selection and commissioning should not happen in separate workflows.
Hysopt Calculator connects them through the same physics-based hydronic digital twin used across the wider Hysopt platform.
That helps engineering and installation teams move from design to correct first-time operation with fewer errors and less rework.
