Subtleties of connecting a warm floor

Underfloor heating can be based on various types of connection schemes. Connecting electrical appliances requires experience. Knowledge of the basic rules for installing electrical appliances will be useful for the competent performance of work..

Features and types

Electrical systems include single or twin cable. The way of laying the heating elements is tape, and the type of cable is resistive. It is also worth considering in more detail the subtleties of connecting the popular infrared floor heating system today.

What are the differences between a single-core or two-core cable? The differences are just in the installation methods. The single-core cable assumes a return to the temperature sensor. With a two-core cable, the circuit is closed with a special lug. Plus the choice of a two-core option in simple installation and installation possibilities in rooms with complex layout.

A resistive cable will provide a uniform temperature of elements in any part of the system, which is often inconvenient. Changing the degree of heating of the cores will be provided by a shielded self-regulating two-core cable. Heating can be correlated with temperature changes in rooms. The state of the environment takes into account a special internal arrangement. Let’s take a closer look at the advantages of two options for heating elements:

Single core cable:

  • low price;
  • withstands high temperatures;
  • less electricity consumption.

Two-core cable:

  • easy installation;
  • invariability of the natural electromagnetic field in the room;
  • no need to install a thermal sensor.

The designation CT, CF, CR will tell you about the correct choice of a two-core cable. The wire must be provided with outer insulation and a copper shield. The device of a single-core element requires a mandatory temperature sensor. In this case, one end of the cable is hooked up to the device. Then the wire is passed through the room. After the second end of the cable is returned to the temperature sensor, closing the system. The presence of the electromagnetic field of the single-core wire can be eliminated by choosing the option with Teflon protection. Protection will qualitatively reduce radiation.

When arranging an IR underfloor heating, it should be understood that the rooms will be warmed up due to the radiation of infrared waves. The principle of operation is similar to the use of electrical cables. The main characteristic is the consumption of a considerable amount of energy. But infrared film has some design advantages. For example:

  • the positive effect of infrared radiation on a person;
  • easy installation;
  • the optional presence of a protective layer when laying such substrates as tiles, laminate, parquet or board;
  • uniformity of warm radiation.

When installing such bases as linoleum, carpet and the like, you will still need a rigid base, which is suitable for plywood. But even in this case, it is easier and faster to install an IR underfloor heating than to lay a cable version. Perhaps this is the secret of the popularity of this species..

Significant electricity savings can be achieved with a water system. A water floor is a type of heating element that consists of pipes pressed into concrete. A liquid, heated by a heating boiler, circulates through them. In apartment buildings it is possible to install the system without an additional boiler. The coolant will come from the main.

The simplest scheme combines all pipes into a single collector. The improved circuit assumes an addition in the form of a three-way valve with a temperature sensor and a thermal head. Let’s take a closer look at all types.

Floor heating connection diagram

The sequential scheme of electric floors implies the following stages of work:

  • determination of the place of laying and the temperature sensor;
  • laying of cable mats / wires;
  • changing the direction of mats / wires if necessary;

  • installation of a temperature sensor;
  • connecting the system to a thermostat;
  • covering of mats / wires with a screed;
  • laying the floor finish.

If the heating elements are connected through a thermostat, then it is worth taking into account the popular types of these devices. They are mechanical or intelligent, controlling the parameters of the environment and the floor itself. Installation can be carried out from a heated towel rail, servo, to a comb.

Installation of a warm floor is available to carry out independently, only if you have confidence in your skills.

Schematic graphics are usually depicted on the body of the temperature sensor or in the passport for it. Connection to the mains can be done through a socket or through a special electrical panel. Today, the most popular devices are electronic thermostats. A separate automatic device connected through an electrical panel will serve to ensure the power rating in the event of a voltage difference. The limitation is the maximum voltage required by the device. This value should be identical to that given by the system..

The installation diagram for electricity is as follows:

  • sensor installation;
  • supply of network cables;
  • the conduit of the system itself.

The conductors of the system are supplied with the corresponding letters or color. An indicator screwdriver can be used to check the conformity of the mains wires. They are not always marked.

If the end of the instrument touches the phase, then a light on it will light up.

To connect the network, follow the steps:

  1. Connect the mains wires to the sensor, pins 1,2. The designations can be viewed on the side of the thermostat.
  2. Connect phase (L) to socket one, connect zero (N) to pin 2.
  3. The cores are connected to contacts 3 (N), 4 (L).
  4. The temperature sensor is connected to 5 and 6.

Next, you can check if the connection is working properly. You need to turn on the device and set the minimum temperature. Then increase the reading to the maximum values.

Water heat-insulated floor

The installation of the system is different, its basic principles are further:

Collector connection:

  • installation of the box so that it can be accessed in the future;
  • installation of shut-off valves;
  • connection of fluid supply and return;
  • connection of pipes to the box. If the pipes differ in diameters, then it is possible to use adapters;

  • installation of measuring instruments that will help in monitoring indicators;
  • installation of a mixing pump. Although the connection can be made without a pump. It is needed to reduce the temperature of the media during overheating;
  • installation of separate boxes for each room, if you need adjustment in separate rooms.

The underfloor heating is connected in series or in parallel. A sequential circuit needs an additional circulation pump to supply fluid. The system is highly efficient. The advantage of the parallel method is that each of the branches of the system can work separately. Bends require the installation of additional shut-off valves. Another positive point is the simplified installation.

Infrared floor heating

Infrared floor heating is connected via temperature sensors. This device will help to save energy and turn your system into an automatic one. A typical installation of an IR film through a thermal sensor has a standard form. As in the case of the cable system, phase and zero cling to the corresponding terminals on the regulator. The wires on the temperature sensor come out of the remaining connectors. A small negative characteristic of the circuit – cable confusion among themselves.

Some beginners use an alternative method of connecting infrared film without crossing cables. In this case, all phase conductors are wound on one side, and zero on the other side. When installing this circuit, you need to very carefully connect the contacts of the same name according to the diagram.

How to connect with your own hands?

The general principles of installation and installation of the system to electricity have already been discussed above. It is worth studying in more detail the installation scheme of certain types.

So, for example, assembly and installation at the first start-up, including heating cables, is possible after the screed is poured, as well as the insulation is laid on the surface. Take into account the peculiarities of the heating element circuits: laying in a snake or in a circle. Cable underfloor heating is the most complex connection system; it cannot be mounted directly without grounding. It is easier to work with electric mats. This is the same cable embedded in a special film. Electricity is connected from a special panel without installing a temperature sensor. Electric films are convenient in arrangement and inexpensive in cost.

A schematic diagram of the infrared film device is usually included in the kit. The installation of the film should be carried out on a flat surface with an insulating substrate that reflects radiation. Contact terminals for connecting circuits are usually already on the film itself. Some types of films can be cut according to special marks.

The features of a circuit with a water carrier imply several types of connection. At the heart of:

  • three-way valve circuit;
  • circuit with a circulation pump.

Installation without a pump is more profitable, since the valve ensures good circulation of the coolant from the water heater. The pipe laying scheme is:

  • spiral;
  • loops;
  • double helix.

Installation and configuration

In order for the warm electric floor to be activated, it is important to think over the place of installation of the temperature sensor in the apartment. This device will facilitate convenient operation and ensure the required temperature of the heating elements..

You can install the thermostat permanently or use a special socket that will work as a separate temperature sensor.

Before connecting the system, it is important to check the screed, make sure that the coating is completely dry.

To connect the infrared film, strip the contacts of the wires that conduct current and clamp them with pliers. Insulate. Connect the floor through copper stranded wires with a cross section of at least 1.5 mm. Thermal sensors are useful for the correct operation of the device. Installation options for devices involve placing on top of a film or using a plastic tube that is placed in a recess in the floor.

If a warm floor is planned in several rooms of the house, it is advisable to provide for the installation of several sensors. This is especially important if the operating modes of the heated premises differ..

Recommendations for use

Floor heating at the present stage is not a luxury, but a household need. The systems can use different types of heating elements. They all assume different operating conditions. It is believed that film types of devices have a long service life.. To make them really work for a long time without repair and replacement, consider simple rules:

  • optimal temperature regime + 20 + 30 degrees;
  • it is impossible to operate film types without sensors of regulation of a certain temperature;
  • do not cover the heated floor with blankets, cardboard paper, furniture;

  • in the absence of a room with a warm floor for a long time, it is not recommended to turn it off completely. It is better to set the sensors to minimum power;
  • do not break the integrity of the installed film. Do not drill, drive in nails, or perform other similar work;
  • turn off the heating system if liquid gets into it. You can turn on the system only after complete drying;
  • for a comfortable stay in the heat, the warm floor can be completely turned off;
  • use the equipment only in accordance with the instructions.
