Testing Underfloor Heating
Testing underfloor heating is an essential part of the installation of any underfloor heating systems, and can prevent a serious, and potentially costly, issue at a later stage. In this article, we will guide you how to testing underfloor heating for various types of systems.
Testing Underfloor Heating Under Tile Mat
To test the under tile heating mat, you will require the following items
Using the multimeter on the suitable setting (2kΩ or 200Ω) test the resistance between the following
These readings should be the same, or within 10% tolerance of the given resistances. If not, please contact us on 01887 822028 for advice. Repeat step during installation & after installation, before laying and after laying tiles also.
Testing Underfloor Heating Underwood foil
To test the underwood heating foil, you will require the following items
You will also be required to know the exact measurement of foil fitted. The foil is made up of 20cm segments to assist.
Using the multimeter on the suitable setting (2kΩ or 200Ω) test the resistance between the following
Using the below calculation to check the resistance
120 x 0.6 x (exact meterage of foil fitted) = Wattage
52900/Ω taken in previous step = wattage.
The above 2 wattages should be within 10% of each other. As foil is a carbon-based foil, these can fluctuate. If concerned, please contact us on 01887 822028 for advice. Repeat step during installation & after installation, before laying and after laying tiles also.
Testing Underfloor Heating InScreed Cable
To test the InScreed heating cable, you will require the following items
Using the multimeter on the suitable setting (2kΩ or 200Ω) test the resistance between the following
These readings should be the same, or within 10% tolerance of the given resistances. If not, please contact us on 01887 822028 for advice. Repeat step during installation & after installation, before laying and after laying tiles also.
