Underfloor heating stopped working, what to do
Underfloor heating gives comfort and cosiness, failure of underfloor heating is a problem, but maybe it is not so complicated and problematic. I will try to explain what to do to people who do not know what resistance is, as well as those who do not have a tester. The presence of a tester in the house indicates that a person understands something about electricity, and a warm floor is not such a complicated system that it is necessary to describe what to do with it. A warm floor consists of three elements, a heating cable, a temperature controller and a temperature sensor. If you are able to identify what has failed on your own, it will significantly reduce the repair time. First, make sure there is electricity in the house. If there is, it is necessary to determine whether the heating cable itself has failed. To do this, switch off the electricity and remove the regulator. There are six wires connected to the regulator, disconnect all the wires and put the regulator aside. Two wires – this is the power supply 220V., the other two are heating cable, two more are temperature sensor, on the terminals of the regulator there are markings, it is not difficult to determine what is where. To determine the operability of the heating cable, we connect two wires of the power supply and two wires of the heating section in a straight line. The power supply cable and the heating section is a three-core cable, the third connection is the ground, usually it is a yellow or yellow-green wire, it is already connected directly, do not touch it. *** Translated with www.DeepL.com/Translator (free version) *** The sensor remains unconnected.
Switch on the power and see what happens. If the underfloor heating still does not heat up, it means that you are out of luck and unfortunately you will not be able to do without a specialist to identify the damage and repair it. If the floor heating starts to heat up, it means that there is nothing wrong with the cable and the problem is in the regulator or the sensor. The floor heating cannot work for a long time without a sensor, switch off the electricity, disconnect the wires and insulate the 220V supply wires while you are away.
The sensor should be lowered into the screed in a corrugated pipe, ideally it can be taken out of there, but if “not everything” was done correctly during installation, it may be difficult to put it back, so it is desirable not to touch the sensor. You take the regulator and go with it to the floor dealer or to the nearest shop selling warm floors, it is desirable to take the documents with you, in case it is still under warranty. The shop or retailer will check the regulator and determine the cause of the failure. If the problem is the regulator, replace it or buy a new one, go home and hook everything back up in reverse order. If there is nothing wrong with the regulator, then the problem is with the sensor. We buy a sensor, come home, try to pull out the old temperature sensor and put the new one in its place. The sensor must be placed in the same place as the old one, it cannot be inserted half the length. When buying a sensor or regulator, ask the retailer to test them in pairs so you don’t have to do it yourself at home.
