Which thermostat for underfloor heating is better?

Floor heating system is a rather useful invention. It allows you to create comfort in the home. In the absence of heating in the house you do not need to worry about the fact that you will be left without heat.

Asking the question of the installation of such a structure, it is necessary to ponder many questions. In order for such an acquisition to bring maximum benefit, additional equipment will be needed. In particular, the need to install a thermostat (thermostat) to optimize the operation of the entire system.

Thermostat is a device designed to control the temperature regime of heating elements.

Special features

The main task of the thermostat for underfloor heating is to control (turn on and off the system), adjust the temperature, as well as the consumption of electrical energy consumed.

It is worth noting that modern devices have such a feature as saving electricity. They allow to reduce consumption by 40-50%. Such regulators, of course, stand out among other models of thermostats. In addition, a reduction in the level of consumed resources can be achieved by using a device that has a two-way thermostatic valve.



From a wide variety of thermostats for underfloor heating there are several main categories:

  • Mechanical;
  • Sensory;
  • Digital;
  • Programmable.

Mechanical thermostatic valve is considered the most simple, but at the same time common type. It is a mixing unit located on a three-way valve. It can also be represented as an electromechanical device. In any of the options, its main purpose is to adjust the temperature indicated on the rotary scale. Models belonging to this group are easy to use and have an affordable price.

It is worth noting that the presence of a three-way valve allows you to apply these devices to underfloor heating water type. It directly adjusts the flow of cold and warm water. He also mixes them and provides water with the desired temperature in the pipethat are used for floor heating. However, such an application is possible only when there is a separate water heating system in the dwelling.

But such cases are extremely rare. That is why the most common are electromechanical thermostats. Setting the required temperature parameters in them is also carried out manually.

The touch thermostat for underfloor heating is also easy to use. In addition, it has a high accuracy rate, while being the most convenient in terms of control. It is worth noting that the cost of devices of this type is quite high. This is due to the quality of functioning and a set of opportunities.

Digital thermostat on the principle of action resembles a device of a mechanical type. The main difference is the presence of a display on which the display of the temperature of the floor surface occurs.

By the way, it is also exhibited in manual mode. However, control is via buttons. They can be ordinary or sensory.

A programmable thermostat for floor heating, in comparison with the above-mentioned types of these devices, has significant advantages. Its main difference is the ability to program the desired temperature regime and all its changes for different periods: days, weeks, months and even years.

In addition, when using such a device, the degree of floor heating is adjusted. That is why they are widely used in the systems of "smart home". Programmable thermostats are able to recognize the presence or absence of people in the room at the moment.

This device is perfect for homes with a large area. Thanks to the intelligent system, it can significantly reduce the cost of electricity and optimize the climate in the home, depending on the outdoor temperature.

Tips for choosing


Focusing on the types of thermostats, you can go directly to the selection of the most optimal option for arranging your home. It should be noted that almost all existing sensors are suitable for controlling heating elements of any type. Therefore, owners of both infrared and cable underfloor heating, as well as water or electric, can purchase this device.

Another positive aspect is the fact that the thermostat does not have to be a product of the same manufacturer as the system as a whole.

If you have decided on the amount of the planned costs and are going to buy a thermostat, you should familiarize yourself with some criteria for the correct choice. First of all, at the time of purchase you need to pay attention to the following aspects:

1. Technical parameters:

  • Type of device, which directly depends on the cost;
  • Sensor type (external or integrated);
  • Uniform distribution of heat over the entire surface.

2. Power ratings indicated on the device. This parameter should be selected with a small margin (20% higher) from the parameters of the entire system. So you will provide her with long service without interruption.

3. Installation method. Embedded instrument types imply the need for drilling holes. Therefore, it is not recommended to buy the owners of wooden housing. The most convenient in this case is the invoice thermostat. It is suitable for any wall, because its installation takes place in the distribution box.

4. Appearance. Manufacturers took care of the attractive design of their products. Therefore, each customer can choose a device suitable for the general interior. In this matter, only the personal preferences of the owner are important.

5. The number of channels. With their help, resource savings are achieved:

  • Buying one device, which should regulate the heating of two rooms, it is necessary to combine them competently;
  • Two single-channel devices are in the same box. This is convenient when there are children in the house. So they will not have access to PU;
  • Dual-zone thermostat controls the heating using a two-way valve, which has two modes: for electric and water heated floor.

6. Control and possibility of programming the device:

  • It is recommended to purchase a device of a mechanical type, if children live in the house. It is less attractive to them and quite simple if necessary repairs;
  • If the floor is covered with laminate or linoleum, then it is advisable to buy a digital-type thermostat. The maximum temperature of heating of such surfaces should not exceed 26º. Only digital thermostats have the ability to customize this parameter;

  • Device installation height. Some models have certain requirements for this criterion. Few people prefer to stoop whenever you need to set a mode. In addition, the presence of children in the family will not allow to make a choice in favor of such a device;
  • Built-in wireless connection. In more modern and expensive models, manufacturers have integrated wi-fi into their products. This greatly facilitates the management process, since it can be implemented through any gadget (subject to the installation of special software).

Guided by these tips and knowing the principle of operation of each individual type of device, you can understand which choice to make. In addition, you can always ask for help from a specialist and get answers to any questions you may have.


After the choice is made and the purchase of a floor heating system is made, as well as a thermostat for it, you can proceed to the most important thing - the installation.

The installation of the system itself, whether electrical elements from infrared film or a heating cable, is performed fairly quickly and does not require special skills. You can order the services of a similar repair from a master or do it yourself.

As for the thermostat, its connection to the heated floor occurs in several stages:

  • First you need to determine the place in the room where the device will be placed. It is worth considering that next to it must certainly be an outlet with a voltage of 220 volts. In addition, you need to provide a sufficient distance between the thermostat and wiring. In this interval will be located automatic switch.
  • When creating an electrical floor plan, it is very important to allocate space for the temperature sensor. It should be located next to the thermostat and not closed with furniture.
  • If you use infrared film for floor heating, the sensor is mounted on the inside of the film.
  • When using a heating cable that fits into the thickness of the screed, the thermal sensor should be protected from exposure to concrete.
  • After the installation of the underfloor heating system is completed, it is worth making a markup on the place intended for the thermostat. If the regulator is built in, then it is necessary to make a niche for its installation. If it is a consignment note, the installation is carried out using self-tapping screws.
  • Upon completion of these actions, you should compare the performance indicators in the heating element of the heated floor with the allowable power in the thermostat. Its maximum should not be less than the load that is applied to the heating element.
  • The last point is to connect the wiring of the heating elements directly to the thermostat terminals. It should be noted that compliance with the connected phases is very important. Most electrical appliances have corresponding lettering or color designations. So, the neutral wire is the letter "N" or blue, and the phases are the letters "L" or "F", as well as black, white or brown.

After performing all the manipulations, it is recommended to test the connected device:

  • Set the minimum temperature;
  • Feed;
  • Start the heating switch;
  • Slowly change the temperature. At the time of the start of the heating elements, you will hear a faint click;
  • Estimate floor heating.

Also, to facilitate the installation of a thermostat to control the floor heating system, the use of a self-regulating heating cable is recommended.

As for the installation of a thermostat for a warm floor of water type, in most cases it is not at all necessary. Distributing dies are actively used for this type of floor heating. This is not a separate element, but a complete system that controls the operation of the contours of the water floor heating. However, in order to save money, the owners still want to see thermal sensors on their systems.

Such a system has a rather simple circuit for connecting a thermostat - mounting a thermostatic head with a remote sensor on a two-way valve. In this case, the regulator works as a timer. That is, water is heated to a certain temperature for a set time.

After reviewing the installation instructions for one or another thermostat, you will be able to install without too much difficulty. In addition, following the simple rules, it will turn out to eliminate some faults on your own.
