Underfloor Heating Design

From floor plan to a contractor-ready PDF with your logo in one tool.

The underfloor heating module in HeatAlgo is browser-based underfloor heating design on the building's floor plan - zones, loops, and thermal calculations for heating installers. Drop in a PDF or image from your architect, calibrate the scale in two clicks, and draw the pipe layout with automatic calculations.

Context

Why designing underfloor heating is hard

Pipe layout design requires CAD-like software costing 1,000-5,000 PLN. You need training, a licence, and a specific Windows machine. For a single project, that's often too much overhead.

Without such a tool, installers sketch on paper and estimate pipe length from experience. A wrong estimate means buying too much or too little pipe, incorrect spacing, cold spots on the floor, and a complaint from the client.

HeatAlgo takes a different approach: upload a PDF floor plan from the architect or client, draw zones directly on it, and design the pipe layout with real-time thermal calculations.

Step by step

How to design underfloor heating

1

Upload the floor plan

PDF, JPG or PNG from the architect or client. Drop the file in and you immediately see the plan in the tool.

2

Calibrate the scale

Mark a line of known length, enter the metres. 2 clicks and the scale is set.

3

Draw the heating zones

Trace each room separately. Each zone becomes an independent loop with its own calculations.

4

Draw the pipe layout

For each zone draw the pipe layout on the plan. Calculations update in real time.

5

Review the result

Pipe length, spacing, heating power, and a warning if any loop exceeds 100 m. Everything in one place.

Features

Everything you need to design underfloor heating

Drop in the architect's plan as a PDF or photo.

Drop in the architect's file and work directly on the existing plan, no redrawing. Handles PDFs and plain photos of the floor plan.

Scale calibration in two clicks.

Mark a line of known length, enter the metres, and the scale is set. From then on every dimension is measured for you.

Draw loops directly on the floor plan.

Zones and loops drawn right on the plan, serpentine or spiral. No moving the project into a separate CAD tool.

Calculations update as you draw.

Area, pipe length, spacing, and heating power recalculated on every change, with a warning when a loop exceeds 100 m.

Unlimited undo and redo, automatic saving.

Every move can be undone and the project saves itself. You continue the work from any device.

A contractor-ready PDF with your logo, on the spot.

The pipe layout with calculations, ready to print and hand to your client on the spot. Your logo and company details on every page.

FAQ

Frequently asked questions

Which floor plan formats can I upload?

PDF, JPG, PNG. Anything you get from the architect or client.

Can I choose serpentine or spiral?

Yes. Draw the pipe layout directly on the plan, serpentine or spiral. Calculations update as you go.

Does the result include pipe length and spacing?

Yes. For each zone you see: area, pipe length, pipe spacing, heating power. All calculated automatically.

What does HeatAlgo cost?

For 14 days you get full access for free, no card required. After the trial we agree on a plan matched to your business.

Can I design multiple floors?

Yes. For each floor you upload a separate plan and draw the zones independently. Projects are stored separately.

What is the maximum loop length?

The system warns you when loops exceed 100 m. You can split a zone into smaller loops to stay within the recommended limit.

Can I change the pipe spacing?

Yes. For each zone you can set a different spacing. The system recalculates the layout automatically after every change.

Does the result include material requirements?

Yes. For each zone you see the exact pipe length and required square metres. Ready data for ordering materials.
