New in March 2025

We’re releasing some important updates to Heatpunk to help you keep your project designs and quotes compliant with the latest industry standards.

• Performance task – The updated performance task will now be applied automatically to all new projects to ensure compliance with MCS 031, which takes effect from 18 March 2025. This update ensures your designs remain fully aligned with the new industry requirements. Learn more about the new task and how this affects your existing projects here.

• Outdoor design temperature (ODT) changes – We’ve updated the default ODTs to reflect the latest CIBSE guidance. These changes ensure more accurate heat loss calculations, but you can still override the values in project settings if needed. See the full list of updated ODT values and how they impact calculations here.
