Pro: Importing Floor Plans
This feature is only available to users with a Heatpunk Pro subscription.
Importing floor plan PDF
Open an existing project or create a new project and navigate to the floor level you want to upload the plan to. Click on the plan button on the left hand side of the page to upload a plan.
Step 1: Upload the floor plan PDF
Click Choose file to browse the files on your computer. If your file has multiple pages, set the specific page that contains the floor plan you want to use. Click Upload Plan to continue.
For additional levels it's important to align the floor plan with the floor below so heat loss between levels is calculated correctly. See Step 4 for how to do this.
Step 2: Set the scale
Use the purple reference length bar to set the scale.
- Drag the reference length bar over to the plans scale or an object of known length.
- Set the size to match and then click on the dimension to enter the relevant value.

Step 3: Add rooms to floor plan
Drag and drop rooms to build up the floor plan as normal, using the PDF plan as a guide. Read more about creating rooms and floor plans to help with this step.
- Click and hold the middle of a room to make the rooms transparent and show the floor plan upload below.
- Click on the walls of a room to turn the transparency off and view the wall and room properties.
Step 4: Repeat for additional levels and align plans
Add level and repeat step 1-3.
After uploading plans for additional floors, ensure the floor plan is correctly aligned with the floor below. Double click and drag to make the plan transparent and display the floor below. You can then align the floors correctly.
