Warm floor connection scheme

The heated floor in the premises can be based on various heating elements. It can be electric or water. But in any case, the key element of its installation is to connect it to the control system.

Wiring plan for a warm electric floor.

The control element in the electric warm floor is the thermostat. Currently, there are two main types of temperature controllers:

• -mechanical, where the desired heating temperature is set by a mechanical rheostat.
• -electronic, where the temperature of the heating elements is set by means of an electronic relay. In such regulators, there may be a programming device that can initiate operation of the heating system at predetermined time periods.

Thermostats of any type are designed to adjust the following types of electric heating elements:

Heating cable. It is an electrical cable with a high resistance, placed in a reliable isolation. When it passes through the power cable, it heats up.

The next type of electric floor heating element is a thermal mat. In this design, the heating cable is placed on the thermal insulation film at a predetermined pitch.

Finally, the heating element can be a special film emitting infrared rays. Its thickness does not exceed half a millimeter and a flat semiconductor heating strip is mounted in its layer.

Wiring diagram for heated electric floor via

thermostat To connect the heated electrical floor to the power cable, it is necessary to connect the thermostat via the thermostat. This achieves savings in the amount of electricity used for heating the room.

As a rule, the wiring diagram is shown on the thermoregulator case or in its passport. Installation of the thermostat can be made independently, without resorting to the services of third-party organizations.

To the thermostat, the power supply cable can be connected directly through the wiring. Also, the thermostat, and accordingly the heating elements themselves, of the warm electric floor can be connected via a regular outlet.

The figure below shows the circuit diagram of the thermostat connection.

It is important to know that the connection of the thermostat to the network is desirable to be carried out through a separate circuit breaker.

One of the variants of the wiring diagram is shown in the figure below.

Calculation of the number of

thermostats There may be several rooms in your house that will be equipped with warm electric floors. In this case, it is advisable to provide the installation of separate temperature controllers and temperature sensors to each heating circuit. This will avoid additional loads on the grid. This is especially important if the heated rooms have different operating modes. So the living room can be heated only during sleep, and the bathroom - only during its use.

For separate installation of thermostats, it is necessary to install individual temperature sensors for each heated space.

Wiring diagram for a warm water floor.

The way of connecting the warm water floor is slightly different from the electrical floor. Let's consider ways of connection of a warm floor with a liquid coolant to heating systems.

You can connect your warm water floor to the main heating. However, this method should be used with a certain attention. Perhaps, the large heat loss of the carrier will lead to the fact that your neighbors will start complaining about the cold. Without damage to neighbors to connect the warm water floor in apartment buildings can be in the premises where the stationary system passes to the reverse flow. Also in this case the water temperature in the heating system will not be too hot.

The big disadvantage of such scheme of connection of water-heated floors will be impossibility of smooth adjustment of the coolant temperature. Even if you mount on the inlet and outlet sections of the heating circuit of the valve - the heating temperature will still depend on the heating of the main system.

Scheme of connection of a heated water floor to an individual heating system.

There is practically no shortage of the scheme for connecting a heated water floor to an individual heating system. However, such a method can only be used in private dwellings.

Below is a schematic diagram of the connection of the heated water floor.

The diagram shows the following components:

1. Thermostatic control valve mechanism. The signal for this part is fed from a remote temperature sensor. In the event that the system reaches the set temperature - it closes the supply of heat carrier.
2. Balancing valve device. It prevents the idle passage of the coolant in the heating circuits. If the coolant supply is cut off, it starts it on a small circle without a boiler.
3. Circulation pump, providing additional pressure of the heating medium in the heating circuits.
4. Safety thermostat. It is placed on the inlet pipe of the coolant and monitors the temperature level in the system.
5. Electric drive of the valve manifold of the water manifold. It is intended for control of valves of heating circuits.
6. The water collector of the floor heating system, distributing the flow of coolant along the contours.
7. Pretended water manifold valve( also bypass), circulates coolant through a small circle.
8. Remote controller for the temperature of the heating medium of the heated floor system There are several installed in the system, which allows you to individually adjust the temperature in each room equipped with heated underfloor heating.

You can also get acquainted with the scheme of connection of heated floor with liquid coolant by watching the training video:

Another option for connecting a heated water floor can be the use of a hydraulic separator. It is a specialized reservoir in which the heat carrier is accumulated. Typically, this capacity is mounted in a collector cabinet in a special wall niche.

An example of this connection is shown in the figure.

An important point in connecting a heated floor with a liquid heat carrier is the installation of a water collector. To it all contours of heating system are deduced, thus temperature and working pressure of the heat-carrier in each contour can be adjusted individually.

Layout and connection of heat exchanger circuits

When drawing up the scheme for connecting a heated water floor, it is also necessary to calculate the location of the heating circuits. Obviously, they should not be in the places where stationary equipment will be located in the room.

There are two main circuits for connecting the heating circuits of the water floor: they are "snake" and "snail"( or "spiral").In regions with a cold climate, it is recommended to use a "spiral" connection scheme, since in this case the whole room will be heated fairly evenly and the floor surface will not experience strong temperature deformations.

Connection of the heated floor according to the combined scheme

The heated floor system can be used as an independent heating system, or in combination with traditional radiators. With this connection scheme, first the heating radiators are connected to the heating medium flow, and then, on the return flow, the coolant passes through the floor heating circuits.

This figure shows a combined scheme for connecting the heated floor.

1. Pump providing coolant circulation.
2. Heating radiators,
3. Heating boiler,
4. Tank with membrane partition.
5. Control device,
6. Shut-off valves.
