Design features of floor heating convectors Floor convectors for heating - varieties, features, installation

Floor convectors are heating devices that are built into the floor. They are called built-in for this reason. This kind of development is still considered an innovation, because it was invented only 20 years ago.

What is it? In a few words, this device can be described as follows - if you plan to install panoramic windows from ceiling to floor in your apartment or private house, then built-in convectors will be an excellent heating option. The thing is that traditional radiators and even standard convectors will simply have nowhere to install.

However, in any case, built-in convectors are much better, and they can be installed, even if you have standard windows, as well as the layout of the room - high aesthetics of the interior with such a heating system will be provided.

General information

Design features

The convector that is built into the floor will be a built-in channel in the floor, and made as a steel box, which is corrosion resistant. Copper piping and an aluminum-type heat exchanger can be located inside the box. From above, everything should be covered with a decorative grill.

Such devices can be divided into two types by design and principle of operation:

  1. Having natural convection, when, due to the density difference, warm air will be replaced inside the appliance is cold.

  2. With forced convection, the device is equipped with a fan of tangential or even centrifugal type. Due to this, the air through the heat exchangers will be evenly distributed, it will warm up faster, and this, in turn, will contribute to the rapid heating of the room.

Principle of operation

Built-in convector types can be installed in the floor along the entire perimeter of the room, with the main focus on the lines along the window openings. Actually, first of all, they will be designed for the installation of such a heating system. By the way, the principle of operation will be based on the fact that air of low temperature will naturally descend into the convector from the window - the conductor of cold, and in the convector it warms up and is pushed into the room by a new stream of cold that goes down from the window.

Benefits of floor recessed products. And now let's consider all the advantages:

  1. Design features of floor heating convectors Aesthetics - the indisputable advantage of floor appliances will be beauty , because you must agree that decorative grilles on the floor surface, from which heat will blow, will create much more comfort than bulky batteries.
  2. The space will be freed up that is not occupied by the usual radiators, and you will also get free access to the door and windows of the balcony or loggia.
  3. The heat from the heating convector will go exactly to the place where it is coolest - along the doors and windows.
  4. The room will warm up much faster than with a classic heating system.

  5. The equipment is lightweight and will not load the floor or foundation.
  6. The temperature of the decorative grill will be no more than +40 degrees, which means there is no risk of getting burned.
  7. Floor convectors will not only heat the room, but also cool it, which will replace devices such as air conditioning.

Weighty, isn't it?

Disadvantages. Among the disadvantages of the underfloor convector for water heating are the following:

  1. There is a need for proper care of the device.

    A little later, we will dwell on this in more detail, but now we note that it is also worth dusting off the classic cast-iron radiators from time to time. For this reason, this lack of heating can be called relative.

  2. Cost - such devices are not cheap at all, and even more so if they are equipped with additional devices.

Please note that there is an incompatibility with the standard heating system - they cannot be installed with each other. Do not go into technical nuances - neither one nor the other system will be able to work normally.

If you decide to equip the room with convectors inside the floor, then you should carefully weigh all the capabilities of the system in relation to the structure that needs to be heated.

The complexity of installation work - you will need to call the master, unless of course you yourself are a self-taught technical genius.

As you can see, the disadvantages are much less, but they are tangible.

Scope of application

Properly selected floor convectors will be the ideal solution for private houses or apartments (restaurants, offices) that have panoramic windows. In the photo you can see heating convectors, which are located in a private house near panoramic windows.

Such a system will be an excellent alternative to mounted radiators in those places where they cannot be installed. In addition, such devices will create an optimal microclimate in the pool, greenhouse or winter garden. Effective in rooms with high levels of humidity, they can work not only to warm the air in the room, but even to cool it. With the help of electronic smart equipment, you can install them in a confined space at the temperature that is required. Please note that there are certain nuances here.

Built-in convectors must never be used in places where water can get inside the heating devices.

Please note that in general there is only one strict limitation - you cannot use this type of convectors to heat rooms where the environment is aggressive. Here we are talking about pools with sea water.

Varieties of devices

Underfloor heating devices can be divided into water and electrical - those that are powered from the circulation circuit.


In such devices there is a heating element, which is called a heating element, it is equipped with plates, and is powered from the electrical network.

So, you plug the device into an outlet and it gets warm. If there is no electricity (for example, there was an accident at the power line), then it will become cold. The photo shows a diagram with an electric-type underfloor heating convector device, and the numbers indicate the constituent elements of the device.

Those that are powered by the circulation circuit

The principle of operation of such an underfloor convector is similar to that in the classic radiator system for water heating - thermal the carrier that is heated from the boiler (diesel / gas / wood) will give off heat to the air masses. Naturally, the heating process will increase, but you will definitely not freeze if the power supply is lost in the house.

Installation and connection

For example, we suggest taking the ideal option, when at first they design and build a room, taking into account the subsequent equipping with built-in convectors, and already after they are embedded in the floor. Otherwise, you cannot do without the help of specialists.


First, prepare a niche in the floor surface. However, it is important to take into account that the devices can be mounted not only in the concrete floor, but further into the raised floor - this is a podium made of wood.

  • Niche depth.

    Manufacturers of such devices advise making it 1-2 cm larger than the height of the convector. This will make it possible to level the box, as well as dock it flush with the floor box. In length and width, it will add from 5 to 10 cm from the size of the box, so that it is possible to fix it as best as possible.

Please note that it is better to place the convector in a niche so that the heat exchanger is as far as possible from the window frames and closer to the room - warm air will flow to its intended purpose faster.

  • Distance from the window.

    It is recommended to indent 5-15 cm so that the air can circulate freely. From the walls (if they are next to each other), the distance should be from 15 to 20 cm so that the heated air does not go to the walls.

  • Design features of floor heating convectors Curtains. Here, manufacturers have already decided to evade the answer, because you yourself must decide how to combine this decorative element with the convector. It is worth acting logically - first, install the heating system, and it will be possible to adjust the curtain for it so that nothing interferes with the circulation of heated and cold air.

  • Heat loss and insulation.It should be ensured that the insulating material is always there, since otherwise the convector will heat the floor nearby, and not the whole room.

Now let's look at how to connect the system.


If we are talking about a water convector, then there are two installation methods:

  • Flexible connection - everything is done with flexible hoses. These are much easier to clean - you can lift the heat exchanger and remove all debris and dust during cleaning.

  • Hard wiring - done by means of a supply valve. This method is much more reliable, but not so easy to use.

An electric convector of built-in type is connected to a 220 V network. The main thing is that all the wires are laid in advance and are hidden under the floor. It is categorically impossible to put outside, and at the same time the cross-section and material of the wire must necessarily correspond to the passport data of the heating convector.

Please note that the connection and installation work should be entrusted to specialists.

The most popular models

The simplest and most objective way to determine which floor convectors for water heating (or electric) are better is to study reviews of real buyers of similar equipment ... This is logical, since you can appreciate all the pros and cons of radiators only in the process of practical use.

It is also important to note the fact that at the moment it will not be difficult to find reviews given the popularity of the device and its widespread use.

It will not be difficult to find reviews posted on the Internet about used floor convectors to find out what is highly valued in a particular convector. Most often, positive reviews are left on products from TeshnŠ¾heat, also on products from the Mohlenhoff trademark, and also radiators from Kerma, Breeze, Eva.

How to choose built-in type devices?

The main guidelines will be the type of room and the heating system, as well as the ratio of the footage of the building and the power of the device, the need for additional options ..

. Let's take a closer look at everything.

Types of heating and rooms

Here the degree of humidity (living room or pool) will be implied. If it is damp enough around, then it is worth looking in the direction of the convectors, whose body is made of galvanized or even stainless steel. Although, almost all manufacturers have switched to a similar material in the manufacture of the box.

You are going to install an electric convector or a water heater - this should also be taken into account and weighed against the capabilities of the wallet, as well as the connection options.

Power and footage

Everything is logical here - the larger the heating area, the more powerful the device will be required. But much will depend on whether the system will be an additional or main source of heat.This will significantly affect the determination of power during the selection of the device, the calculation of power is not complicated - for each cubic meter of volume, 40 W of power is required. Multiply the data to get an approximate value.

The height of the ceiling will also play an important role, and the more it will be, the more powerful the convector should be.

Availability of additional options

Manufacturers try to offer various options for additional equipment of built-in convectors. These are air supply with natural convection and a turbocharger with a forced system; there is also a thermostat, the ability to set a certain temperature that the device will constantly maintain, as well as ventilation and cooling functions. We also invite you to watch useful videos that tell you how to install an underfloor heating device.

Operation and maintenance

Almost all manufacturers advise cleaning convectors a couple of times a year - before and after the heating season, but the best option would be to direct order in boxes on the floor 2 times a month.

First, turn off the electrical power and stop the supply of thermal media. Next, you should remove the decorative grille and the electric fan, if any. Carefully lift the heat exchanger and clean the box, as well as other parts with a vacuum cleaner with a special narrow nozzle, and if possible, wipe with a damp soft cloth. Do not forget to replace the protective grill, as it is forbidden to use the device without it.
