System Sizing

Design your system layout with our drag-and-drop features. Connect equipment (e.g. heat pump) and components (e.g. heat emitters) to visualise the entire setup.

CIBSE-verified calculations are automated and all systems are accurately sized with valuable insights like system volume and index length.

Reports Icon


Generate comprehensive MCS-aligned heat loss reports branded with your logo.

The reports include room-by-room heat loss, emitter summaries, heat pump systems performance, domestic hot water energy usage, and costs, giving you and your clients a clear overview of the project’s performance.

Large Domestic Renovation, UK

"Pipe sizing is a dream with h2x being able to quickly change pipe types from copper to MLCP.

Being able to set a velocity limit of 1 means we have all the pipe sizes calculated with correct flow rates and velocity.

h2x takes away the worry of a miscalculation or undersizing of pipe work potential."


Greengate, UK

"I would estimate over the length of this project, I have spent 50% less time designing than I would on our previous software.

The ability to output the design straight into Revit assisted clash detection and coordination."


Salon Republic, USA

"The quality of the designs saw significant improvement with the adoption of h2x."

"The software offers precision through detailed result outputs and advanced options for efficient pipe sizing, allowing heating engineers to optimize based on parameters like maximum velocity and pressure drop."
