I am testing the underfloor heating system to see if it works, what setting should the multi-meter be on to test floor probes?

When testing electric underfloor heating and checking the resistance of heating cables, a multi-meter should be used to test both the heating element and floor probe before, during and after installation by using the Ohms scale.

This will tell you whether the heating system and/ or floor probe are working correctly and that they have not been damaged. To test the floor sensor the multimeter should be set to 20 K (20,000) ohms. The reading you get back will depend on the model of thermostat installed. Resistance readings for heaters can be found in the relevant installation manual for that heater.

Testing underfloor heating systems before and during the installation is important as it will tell you whether the system has been damaged during installation.

Testing the system before installing the final flooring will give peace of mind in knowing the heater is working and will ensure that no damage has occurred to the heater. Should the heater have become damaged during the installation, the Warmup SafetyNet™ guarantee will replace the heater for free; they will provide another heater of the same make and model for free, providing the terms and conditions have been met.
