heating circuit

An electric heating circuit is a wire that is made to a certain length and cannot be shortened. The installation company must install the entire length of the heating cable. Each conductor is terminated by a supply conductor, the so-called cold end, the length of which can be adjusted as needed.

 The advantage of the electric heating circuit is greater flexibility during assembly, especially in fragmented and irregular rooms, when avoiding furniture, etc. Another advantage is the variability of the surface power and the lower installation price.

The disadvantage is significantly more demanding assembly, where it is necessary to create loops of the heating cable and fix the cable to the base.

Composition of heating wires
Electric heating circuits are made only from resistance wires, which are the most widespread type of heating wires. The core of these conductors is from the so-called resistance (resistive material), which heats up when an electric current passes through it. The electrical voltage is standardized, but the resistors are manufactured with different resistance values. By calculation, it is then possible to determine how long the wires must be in order to have the required power at the given voltage - that is, to heat, but not overheat at the same time. Therefore, resistance wires cannot be sold by the metre, but are only sold in specific lengths, including connecting wires - the so-called heating circuits.
