Why Isn`t My In-floor Heater Working?

It is quite a common problem when the floor heating does not warm up well after installation or a long break in operation. There can be several reasons for this malfunction, as well as options for fixing it, so let’s consider the possible options.

Improperly selected heating cable or insufficient thermal insulation layer. The power of the cable should be selected according to the technical conditions of the room where the heating system will be installed. Incorrect calculation of the power or area of the underfloor heating, as well as a thin layer of thermal insulation can cause poor heating of the underfloor heating.

To fix this problem, we recommend contacting a professional who will check the system and make recommendations on how to fix it. Incorrect calculations are one of the main reasons why electric underfloor heating does not heat properly.

– Incorrect installation of the underfloor heating. If the underfloor heating turns off almost immediately after the thermostat is turned on, the temperature sensor location is most likely the problem.
– Mechanical damage of the floor heating. Damage to the heating cable is possible during installation. To determine if the cable is damaged, disconnect the floor heating from the thermostat and measure the resistance of the cores. Compare the measured value with the data given in the operating instructions, there should be no deviation from the normal range

– Technical parameters of the power grid. A low voltage in the house can also be the reason for poor underfloor heating. The floor heating can be ineffective if you have selected a cable with insufficient power density.
– Thermostat and underfloor heating sensor malfunctions. Faulty control equipment is often the cause of cold underfloor heating. You should check that all the cables are correctly connected and that the regulator is working properly.

If the cause of cold underfloor heating has not yet been identified, then the damage is because of one of the three elements of the system: a thermostat, temperature sensor, heating cable.

After running diagnostics and identifying the malfunction of the heating system, you can fix it yourself, or call for help from specialists. But it is necessary to take into account that it is possible to find the place of the heating cable damage in the screed only with the help of special equipment.
