Not warm floor heating, what to do

Electric floor heating helps provide comfort in any home. This is possible only if it is properly functioning. But often the surface temperature below that at which the counting. In addition, the system can not work at all, that is not warm. Is it possible to salvage the situation? Read on.

Bad cable insulation. It may also be properly selected, its power. It is important to find out these details before installation of the floor. To objectively estimate the temperature of the floor, turn it and wait until heated, then compare the component surface temperature at the place where the temperature sensor is installed, and the temperature, which is shown in the thermostat.

Improper installation. Often, simply turns off the regulator. This is facilitated by the fact that you have it installed wrong. For example, too close to the heating cable or on top of it. But if you spent assembling according to the technology, the temperature will be responsible desired.

Damage to the cord. Look to him, whether it intact. When pouring the screed or tile installation it could be damaged. To check this, turn off the thermostat, and then the cable from it, and check the DC resistance is established between the conductors. The normal value for this parameter is specified in the passport system. Ibid indicated by its tolerance - about 5%. If such information is not married, then for calculating the resistance of the cable using the following formula: SC (ohms) \u003d voltage squared (B) / power cable (W).

The results can be characterized as follows:

If floors are consuming a lot of power, then we can talk about defective insulation due to short circuits.
Too low power - certificate continuity of the cable chain, they allow an electric current, reducing the efficiency of the system.
If there is no resistance of the cable, then it is possible that short circuit.
When the passport does not indicate the power, it is conventionally received 150 watts per 1 square meter.

In addition, it is necessary to check the insulation resistance - between the heating residential and braid cable. Its value should be above 1 Mom. If damage is detected, look for a section of a mechanical malfunction. In the case of a cable under the screed repair, as a rule, it is impossible. It is easier with the film floor of things - lift the coating and try to find a damaged area.

Breakage of the system sensor. After you examined the cable for integrity, pay attention to the function of the sensor. For verification, the resistance is valid and specified in the instructions. Some digital regulators in case the sensor is faulty, give the appropriate message. If you have found a breakdown, these devices should be replaced, even in a situation with the filler floors. After all, it is in the outgoing tube.

Fault thermostat. Look, the connecting terminals are tightly tightly. The voltage set on the conclusions of the cable should be equal to the power voltage when the thermostat is turned on. Check the device using a multimeter. Take the thermostat, connect the power to it, and then the sensor. Catch off the ends leading to the system and set the temperature value that is maximum possible. When the internal relay turns on, on the terminals, which are intended to connect the system, the voltage will occur. After that, it is necessary to twist the knob of the regulator in the opposite direction. Find the minimum temperature to work the relay. An absence of voltage will seem at the multimeter. If the regulator malfunction, replace it, which is much easier to do than to open the floor.

Low power voltage. Sometimes the reduced operational efficiency of the warm floor is related to the fact that the supply voltage supplied below that the product works with. If the voltage fell by 10%, the system's power of the warm floor will decrease by 19%. Therefore, when choosing a heating cable, give preference to a wire with a good reserve of specific power. But if you did not provide for this, buy a device that increases the voltage, or install the voltage stabilizer to the whole house.

Thus, it is important when installing a warm floor strictly follow the technology of work, so that it is subsequently not encountered with its not effective work.
