Underfloor Heating Calculator
Calculate the total pipe length and flow rate for underfloor heating based on room area and pipe spacing.
How to Use the Underfloor Heating Calculator
- Enter the dimensions of the area or structure (length, width, height).
- Specify material parameters if prompted (thickness, overlap, etc.).
- Review the calculated material quantity and coverage area.
- Use the results to plan your purchase and budget.

常见问题
How is pipe length calculated?
Pipe length is calculated by dividing the room area by the pipe spacing (in meters). A 10% reserve is added for connections and bends.
What is the recommended pipe spacing?
Standard pipe spacing is 15–20 cm for main rooms and 10–15 cm for bathrooms and highly insulated spaces.
How is the flow rate estimated?
A typical flow rate of 0.3 L/min per m² is used for standard underfloor heating systems.
Why add 10% reserve?
The 10% reserve accounts for pipe bends, connections to manifold, and routing around obstacles.
