Heat Loss Calculations
h2x lets you perform accurate heat loss calculations more efficiently, with intuitive drag-and-drop features, branded drawings, and export-ready reports.
Why Use h2x For Heat Loss Calculations?
Heat loss calculations can be slow and frustrating, often involving tedious steps and manual inputs to get precise results.
However, h2x improves the process by automating the calculations, accurately sizing systems, and generating detailed drawings and reports.
Automated Calculations
Upload your plans, trace around each room, and h2x will automatically calculate the heat demand based on your chosen materials, internal temperatures, and air change rates. For existing buildings, you can draw the layout manually or import a LiDAR room scan using apps like magicplan.

System Sizing
Use smart layout tools to draw pipework or ductwork and connect to system components quickly, with calculations running in the background. You can reposition and adjust layouts at any stage without losing accuracy. System sizing is optional, but when used, it's backed by CIBSE-verified calculations and can be tailored to different international standards.


Drawing Exports
For heat loss projects, you can export detailed PDF drawings that include your own cover sheets, notes, and title blocks, which are perfect for sharing with clients and installers. If you're also designing the system in h2x, CAD and Revit exports are available.

Report Exports
Once your heat loss calculations are complete, you can instantly download a clear, room-by-room report to support design reviews and client approvals. If designed, you also have the option to export the system Bill of Materials with key specifications.
