Heat Load Software Comparison for HVAC Teams
Which software fits which heat load workflow? This overview groups specialist tools, energy platforms, online reports and Prometo as a PDF and takeoff workflow.
Short answer
If calculation depth is the priority, start with specialist software. If PV, heat pumps, offers and project processes matter, evaluate energy platforms. If the project starts with PDF floor plans and room data, Prometo is an early-stage beta workflow to consider.

From floor plan to reusable project data
The same basic structure matters across the workflow: start with project context, check room data, then carry cleaner information into the next technical step.

Questions about heat load software selection
Which type should I compare first?
Start with the workflow: full calculation, broad energy project, quick online report, scan workflow or PDF plan preparation.
When does Prometo fit?
When existing PDF floor plans, room data and takeoff need to become a cleaner basis for later heat load work.
Does this replace professional checks?
No. Every software choice still needs project-specific technical review and responsible use.
