Termofol Heating Film Resistance Calculator – An Essential Tool for Every Installer

Termofol Heating Film Resistance Calculator – An Essential Tool for Every Installer

In the age of modern, energy-efficient heating solutions, more and more investors are opting for electric underfloor heating in the form of heating films. This choice brings a number of benefits – thermal comfort, low operating costs, the absence of visible radiators, and quick and clean installation. However, correct installation of the system and its technical verification are crucial. For this purpose, the resistance calculator for systems based on heating films and heating mats from Termofol was created.

Why is the resistance of the heating system so important?

Resistance is one of the basic electrical parameters that allows us to assess the proper functioning of the heating system. Its value informs us about:

• the correctness of connections,
• continuity of heating circuits,
• absence of short circuits or mechanical damage,

If the system has been installed incorrectly, the resistance value significantly deviates from the expected. This can lead to ineffective operation and overheating of the wires.

How does the heating film and mat resistance calculator work?

To simplify the verification process of the installation, we have prepared an intuitive online tool – the Termofol system resistance calculator. With it, you can:

• calculate the total power of the system based on the selected area and unit power,
• know the theoretical resistance value that you can compare with the measurement taken with a multimeter,
• ensure that your heating system is functioning correctly before proceeding to the next stages of finishing work.

Parameters used in the resistance calculator:

• heating area (m²),
• unit power (W/m²),
• power supply voltage (default 230V).

Formula used in calculations:
R = U² / P, where:

• R = resistance [Ω],
• U = voltage [V],
• P = total power [W].

When should you use the resistance calculator?

It is worth using the calculator:

• After laying the heating film, but before covering it with panels or other finishing materials.
• Before the technical acceptance of the installation by the investor or supervising inspector.
• In the case of servicing or diagnosing an older installation.

This is a particularly useful tool for installation teams, but also for individual investors who want to independently monitor the quality of the work performed.

Calculating resistance step by step

1. Measure the heating area, e.g., 10 m².
2. Select the unit power of the heating film, e.g., 140 W/m².
3. Enter the data into the calculator.
4. Compare the calculated resistance value with the measurement result from a multimeter.

Example: 10 m² x 140 W/m² = 1400 W
R = (230 x 230) / 1400 = 37.79 Ω

What is the significance of correct resistance for the heating system?

• Ensures proper installation execution.
• Extends the lifespan of the heating film.
• Is the basis for warranty registration of the system.

What is the significance of correct resistance for the heating system?

• Ensures effective operation of the installation.
• Protects against overheating of the wires.
• Extends the lifespan of the heating film.

Termofol Resistance Calculator is a practical tool that should be in the arsenal of every installer and investor. It is a simple, free, and quick solution that allows you to ensure that the electric underfloor heating has been installed correctly.

We encourage you to use it whenever you want to avoid costly corrections and ensure the highest standard of heating installation execution. Remember, in our online store, you will find all the necessary accessories for installation!
