How to make a warm floor on the balcony. We make warm floors on the balcony with our own hands: infrared, electric, water Warm floor system on the balcony

In our apartments, where every square centimeter of space is used, making a heated floor on the balcony and loggia with your own hands and using them as an office or relaxation area is a tempting solution. It's nice to go out on the balcony with a cup of coffee in winter, feeling the warm floors with your bare feet!

Warm floors on a balcony or loggia are also necessary when additional insulation and heating of a given room is required. For example, if you want to use it as a separate room (for example, an office) or arrange a winter garden.

What is a “warm floor”?

A warm floor is a room heating system in which the heating elements are located deep in the floor and do not require the installation of radiators. The technology is relatively new, but it is quite possible to make a warm floor on a loggia with your own hands.

Today there are three known floor heating systems with different coolants:

Water heated floor;
Electric heated floor has two subsystems:

Cable
Heating mats

Film (infrared) heated floor.

In a water heated floor, as the name implies, hot water is used.

Despite its apparent simplicity, this option can be implemented in apartment buildings not suitable for the following reasons:

in the heating system the coolant temperature is 90°, for heated floors no higher than 40° is required;
coolant pipes laid on insulation and embedded in a screed whose thickness is 20-30 mm greater than the diameter of the pipes will significantly raise the floor level. It is impossible to maintain the clear height from floor to ceiling of 2.4 m required by the standards with a floor height of 2.8 m without taking into account the thickness of the ceiling;
To connect to the heating system, permission from the housing authority is required;
If you manage to obtain such permission, and the ceiling height allows you to make a warm water floor, you will need a complex system for regulating the temperature of the coolant, and the heated floor will only be warm during the heating season!

If your goal is to install a heated water floor on the balcony in a cottage with an individual water heating system, then this system is optimal.

Electric heated floors are easier to implement. With minimal electricity consumption, its device does not require permits. Difficulties may arise when laying cables, but installation of heating mats is simple and accessible to a person without builder skills.

Film heated flooring is even easier to make; it does not require screed. Heating films are placed in a layer of tile adhesive (if the floor covering is tiles), or covered with a backing (in the case of a laminate flooring).

Infrared floors are not much more expensive than heating mats. Cable floors are cheaper than mats, but a thick screed is required, which is an additional waste of money and time, since the screed takes time to mature.

Floor insulation is a necessary preliminary stage

We begin the work of laying heated floors of any system by insulating the concrete slab of the balcony or loggia. This step is necessary if you do not want to heat the street along with the floor. Even if the neighbors below have insulated their balcony, insulating yours is still necessary. You will need materials:

Several solid bricks;
Vapor barrier material;
Insulation;
Cement-sand mortar for masonry;
Wooden beam with a section of 50x50 mm;
For the subfloor - moisture-resistant wood-shaving, wood-fiber or cement-bonded particle board;
Level;
Self-tapping screws.

At this stage, you are making a warm floor on a loggia or balcony - the difference is small: from the point of view of material consumption for the loggia, you do not need brick and mortar - there is a wall around the perimeter from the very beginning.

We begin laying the heated floor on the balcony by laying a brick side along the outer edge of the slab. We place the brick on the mortar on its edge, the side is 130 mm high (120 - brick and 10 mm mortar). After 3-4 days, when the solution has set, we place a layer of vapor barrier on the cleaned, washed and dried base. The vapor barrier protects the insulation from absorbing moisture from the air; wet insulation does not work.

A special one is used as a vapor barrier non-woven material– geotextiles or rolled bitumen-polymer materials (technoelast, uniflex). A budget option is polyethylene film.

It is not recommended to use materials such as roofing felt (cardboard impregnated with bitumen), roofing felt (leather or fabric impregnated with bitumen), glassine (kraft paper impregnated with bitumen) for vapor barrier - they last up to 5 years, and they are only permissible in temporary structures . The vapor barrier is laid dry.

On top of the vapor barrier, we build a frame from timber on self-tapping screws, the frame cell is no larger than 60x60 cm. The timber for the frame must be antiseptic (protected from rotting in a humid environment) and impregnated with a fire retardant (fire protection). Using wedges made of wood or chipboard, we bring the frame to the horizontal level at the building level. We put insulation into the cells of the frame.

As insulation we use slabs based on stone (basalt) wool - effective lightweight material with excellent thermal characteristics, 50 mm thick. How budget option– slabs made of extruded polystyrene foam grade 35. The insulation has zero water absorption, low density and thermal conductivity. Both materials belong to the non-flammable group. We cover the insulation with another layer of vapor barrier, which we fasten to the frame with a stapler.

We lay a subfloor on the frame - cement-fiber, wood-shaving or wood-fiber moisture-resistant boards, and fasten them to the frame with self-tapping screws. If you have chosen a water or cable heating system, the heating elements of which are placed in a screed, we recommend using a cement-bonded particle board for the subfloor, as it is the most resistant to moisture.

The insulation is complete, we proceed to the installation of the heated floor.

DIY water heated floor on the balcony

How to make a water heated floor on a balcony? Having purchased the required materials -

coolant pipes,
foil gasket,
temperature sensor,
thermostat,
dry mortar mixture for screed,
vapor barrier,
damper tape -

let's get to work. The technology for making a water heated floor on a balcony is not complicated, but there are some subtleties:

a foil insulating pad is spread over the subfloor to reflect the upward flow of heat;
if a warm baseboard is planned, a groove is made in the wall around the perimeter of the balcony for the coolant pipe at the level of the finished floor;
the coolant pipes are laid out with a gap of 30-40 cm and connected to the collector;
we place the temperature sensor, mount the thermostat on the wall in an accessible place;
A damper tape is glued around the perimeter of the wall to compensate thermal expansion screeds for temperature changes;
perform a screed - pour a solution of light, fine-grained concrete or another recommended by the manufacturer of the floor system. The screed must be uniform, without voids, and 20-30 mm high than the diameter of the coolant pipes. The air is expelled with a brush. The horizontal line is checked using beacons. The screed is left for 3-4 weeks to mature;
cover the screed with a layer of vapor barrier;
lay a clean floor.

For a water heated floor on a balcony or loggia, a ceramic tile coating is ideal; a laminate can be laid that is approved by the manufacturer for use for a water heated floor.

The covering of a water heated floor can be linoleum or carpet.

If you want a warm baseboard, to install the coolant pipe you need to make a groove in the wall around the perimeter of the loggia or balcony, otherwise the insulated baseboard will protrude from the plane of the wall by 80-100 mm. Installation of a water heated floor on a loggia completely repeats the above diagram.

Electric heated floor on the balcony

Installing an electric heated floor is easier than installing a water one. Here, such stringent conditions are not imposed when pouring the screed, and the screed itself is thinner. Main stages:

Laying a foil pad that reflects heat.
Layout of heating cable or mats according to the manufacturer's instructions, installation of the system under a warm baseboard;
Installation of a temperature sensor and thermostat, connecting the supply and return cables to the power supply system.
Gluing damper tape around the perimeter of the walls;
Filling the screed with a light mortar, 15-20 mm thick, along the beacons, forcing out the air.
Cleaning floors and baseboards.

For an electric heated floor on a loggia or balcony, any material is suitable as a covering: ceramic tiles, natural stone, laminate, linoleum - it all depends on the taste of the owner.

Now let's look at each stage in more detail.

Preparatory work

First you need to remove all layers of old flooring from the balcony. Only clean concrete should remain. The surface must be cleaned of dirt and dust so that all layers of the future floor can be installed perfectly.

To install an electric heated floor, it is necessary to obtain a flat and insulated surface. Therefore, it is necessary to make a subfloor that will accommodate a layer of insulation. The subfloor must be high enough, but not violate the following technical requirements:

the step between the room and the balcony should not exceed 15 cm;
the total height of the balcony must be more than 2.4 meters;
the height of the balcony fence must be at least 1 meter;
if there are small children in the house, the minimum height of the fence increases to 1.5 meters.

Work on floor insulation on the balcony begins with the creation of a subfloor.

After completing the insulation work, the balcony fencing can be extended. However, you should not make the subfloor too high. This will reduce its durability and make using the balcony not very convenient for apartment residents.

Read more about preliminary work Before laying a heated floor, watch this video:

Insulation of the base of the balcony

On concrete base For the balcony, screw the transverse beams from timber at a distance of 40-50 cm from each other. They do not need to be leveled in height, since the longitudinal beams will be responsible for the evenness of the floor.

Then screw the longitudinal beams to the transverse beams - after 25-30 centimeters. Select the highest point on the longitudinal beams and level the entire floor using wedges or pieces of chipboard. When placing them under the beams, make the base of the floor as level as possible.

The entire space between the beams must be filled with insulation. Suitable, for example, mineral wool.

Lay on the finished floor base chipboard sheets. You cannot use simple plywood or boards here. Peculiarities of floor operation will quickly render the boards unusable. The chipboard is screwed to the longitudinal beams using self-tapping screws.

Next you will need construction foam. With its help, you need to seal the seams between the chipboard sheets, as well as between the sheets and the walls of the house. This will ensure proper insulation of the future floor. On this rough work are ending.

Electrical cable installation

The next step in preparing the heated floor is installing the electrical cable. A special heat cable is laid in a “snake” pattern, and the laying pitch (the distance between cable turns) must be calculated in each individual case.

If the step is too small, a huge amount of expensive cable will be lost, and the apartment owner will receive unpleasant bills every month from public services. If the step is increased, the efficiency of the floor will not be high at all.

Therefore, the calculation of the heat cable laying pitch must be performed using a special formula:

L = Wud.cable*100/Wud. gender

Formula values:

L – heat cable pitch length, cm;
Wud.cable – power required per meter of cable (on average 20 Watts/min, depending on the type of cable);
Wud. floor - the specific power of the floor, which is calculated per square meters. The normal specific power indicator is 200-230 W*m2.

The cable should be laid along the balcony. Every bend in the heating cable is a loss of energy and efficiency of the floor. On standard balconies with an area of about 5 square meters, the laying step is approximately 10 cm. This optimal distance between the wire.

Watch this video to see the installation of a warm electric cable floor visually:

Connecting a heated floor

The cable is fixed to a special mounting tape, laid in a snake along the entire future floor of the balcony. Then the heat cable is connected through the thermostat to the network. This device is necessary to regulate the heating of the heated floor.

It is also necessary to connect a floor temperature sensor. Otherwise, you will not be able to monitor the normal operation of all systems. If you are thinking about how to insulate a cold concrete floor on a loggia with ideal conditions under the tile, then installing a regulator and sensors is simply necessary. Different tiles will reduce the efficiency of heating the balcony.

After completing the connection of all necessary devices, you need to test the system. We check the integrity of all electrical connections and the operation of each cable section. If you miss a mistake at this stage, it will be very difficult to correct it later.

Screed and finishing for electric heated floors

The next step is the screed. It is filled with liquid cement mortar and serves as the basis for the future finishing of your balcony. Do not use metal elements to reinforce the screed. This may cause malfunctions electrical equipment warm floor.

After all the work is completed, the balcony should stand for about five days. During this time, the screed will dry completely and it will be possible to lay the finishing material. It is not recommended to use parquet or linoleum, because these materials are heat insulators.

The best option for this type of balcony insulation is tiles. It adds efficiency to the electric balcony heating system.

Tiles are the optimal covering for an electric floor on a balcony

Installation of film (infrared) heated floor

In terms of ease of installation, infrared heated floors hold the lead among all systems, since they do not require screeding. Step-by-step progress of work:

Lay out the heat-reflecting pad;
We lay out and install infrared films into the system, including a warm baseboard;
Install the regulator and temperature sensor;
Lay the substrate;
We carry out finishing coating and install skirting boards.

Film heated floors are quickly installed, used immediately after installation, and are characterized by uniform heating of the floor surface. For covering in this system, it is best to use laminate and other wood materials: boards, parquet, and carpet.

Film heated floors are characterized by low energy consumption and a service life of up to 50 years.

If one of the sections fails, the system will continue to operate, and repairs will not be difficult. The higher cost of materials is offset by low operating costs.

As a specialist comment

Choosing a heated floor system is a matter of economics and consumer taste. The installation of a heated floor on a balcony is fundamentally no different from the installation of a heated floor on a loggia.

Without considering the water heated floor system as not being widely used due to legislative restrictions, of the other two systems, both electric heated floors and infrared have no restrictions.

The choice of finished floor covering affects the choice of underfloor heating system:

Tiles are good for any system
Laminate and other wood materials, linoleum, carpet - best choice film heated floor.

When using laminate and other wood materials, linoleum, carpet, make sure that precipitation does not fall on the floors - the balcony or loggia must be glazed. It is better to consider the installation of a heated floor on a balcony or loggia as part of a comprehensive insulation system; use the same materials for insulation.

Installation of heated floors on a loggia or balcony with my own hands– interesting and useful process, which does not cause any special problems for the skillful owner of the premises. Anyone who takes the process seriously can do all the work with their own hands.

What are the advantages of heated floors on the balcony?
What is the difference between modern options heated floor for balcony

People use various heat sources for their balconies and loggias. As a rule, heating systems are installed in the floor, due to which the optimal temperature is established in the room and it is very comfortable to be in it. If the warm floor on the balcony is arranged according to all the rules, then it performs its function properly and provides the desired temperature.

In this article we will talk about whether it is possible to install a heated floor on a balcony, and we will provide expert recommendations for choosing heating system and consider all the nuances of installing such equipment.

Do you need a heated floor on the balcony and what is it?

In Moscow, heated floors on the balcony of an apartment or house are an excellent modern alternative traditional way home heating. Evenly distributes heat throughout the room and creates optimal temperature conditions - such functions are performed by a warm floor on the balcony. Reviews from satisfied owners indicate that installing such a system is more than justified. Consequently, the question of whether to install a warm floor on the balcony disappears by itself. For a balcony this is the only rational solution due to the limited square footage. The warm floor on the balcony provides heating of the air from below, since the flooring acts as a heat source. The most popular today are electric and water heated floors connected to the main heating system. One of the latest options- heating based on amorphous metal strip.

A warm floor on the balcony allows owners to stay warm even when it’s freezing outside. Cold air heats up below and gradually rises. This temperature distribution allows a person to feel as comfortable as possible.

The warm floor on the balcony has high heat transfer, which directly depends on the heating element. Unlike a heating radiator, the floor footage is much larger.

It is interesting that the design of a heated floor was first used in Ancient Rome to heat the baths. The system consisted of channels hidden under marble slabs. Heated air passed through them from the stoves. Modern systems much more advanced, but the principle of operation remains the same.

Is it necessary to install heated floors on the balcony? Only you can decide. But, weighing the pros and cons, remember that heated floors are an excellent solution for a balcony.

Advantages of heated floors on the balcony

So, heated floors on the balcony - is it possible to install this system? Compared to simple radiators, it is much more efficient. The system is perfect for both small and large rooms. Since a certain air temperature is maintained due to constant heating from below, very favorable conditions are created for the inhabitants.

We list the key advantages of the “warm floor” system:

The efficiency of the latest heating system is much higher compared to other types of equipment. This floor generates more heat, which provides maximum comfort.
The heating element emits a huge amount of thermal energy, but it itself heats up weakly.
Warm floors are a modern and aesthetic solution. Radiators are quite large devices. They take up a lot of space and often don't look very nice. A warm floor on a balcony or in any other room does not need to be decorated, nor does it need to be kept clean, because all the elements are hidden below.
Installed sensors allow you to easily and conveniently regulate the temperature. The system is automated and functional.
Warm floors have a very long term operation. Water structures are considered the most durable. Although a water heated floor on a balcony is not a very rational choice.
You can install a heated floor on the balcony yourself, without any special practical skills. In addition, such a system does not require special equipment.
By warm floor It's nice to walk barefoot. Your feet don't get cold, even if it's frosty outside.

A warm floor on a balcony can replace a full-fledged heating system due to its lightness, efficiency, economy, durability and aesthetics.

Which heated floor to choose for the balcony

We looked at the advantages of heated floors on the balcony. What is better to choose?

The design of a heated floor includes many heating elements - cables and pipes. There are 3 types of systems: water, film and electric, that is, heat is generated respectively by water, infrared film or cable (separate or tied into heating mats).

Each heated floor design has its own characteristics and advantages. There are also general characteristics. Operation different types systems may have their own nuances. But all of them are installed on a special thermal insulation - a heat-saving layer. After this, a cement screed for the heated floor on the balcony is made and laid flooring. This is how a warm floor for a balcony is installed. Which is the best option to choose? Let's look at each in detail.

Water. This system is connected to an autonomous network, but the water heated floor on the balcony is from central heating not worth considering. There are several reasons for this: such a structure is quite difficult to install on the balcony, since it weighs a lot; such an opportunity does not always exist and is associated with big problems(hydraulic calculation of the network, coordination, etc.).

One of the advantages of such a floor is excellent heat transfer, and therefore it is perfect for heating large rooms.

Electric. It is very rational to use heating cable elements for loggias and balconies. The thickness of the screed will be small - 5 cm. Air does not accumulate in the structure, due to which the system lasts a long time and does not overheat. Installation requires an electrical cable, which is secured with a “snake”. The heating elements are laid in sections, a cement-sand screed is made and a coating is placed on top. That is, you can install an electric heated floor under the balcony tiles.

Remember: The entire structure can be used only a month after installation. Electric underfloor heating operates through a thermostat.

Film. Often, insulation of a balcony with a warm floor is carried out using infrared radiation technology. The heating element is a thin film with graphite strips and conductors. Current is supplied to the conductors through a thermostat. Film heated floor on the balcony and loggia – perfect solution, as it is easy to install and has great energy efficiency. But there is also significant drawback- high cost. Experts recommend such designs for rooms with a small area.

How to choose the right heated floor for a balcony

First of all, when choosing a warm floor for a balcony, look at thickness concrete screed . To install a cable heated floor efficiently, the screed must be at least 5 cm thick. If it is not possible to lay such a layer of concrete, then it is better to opt for an infrared or heating system with heating mats. It should be taken into account that when installing heating mats, the floor will increase in height by 1 cm, while the installation of infrared heating film is carried out immediately under the floor.

Also, when choosing a design, consider flooring material. For warm floors on the balcony under tiles, concrete, stone, porcelain stoneware, it is better to install a cable one. Warm floors on the balcony under laminate, carpet, PVC or linoleum - in the form of heating mats. You can lay an infrared heated floor on the balcony under linoleum, laminate or carpet.

When laying wood flooring, you should remember that its thermal conductivity is significantly lower compared to flooring made from other materials.

How to calculate a floor system for a heated floor on a balcony

When choosing a heated floor for a balcony, it is important to correctly calculate the power of the heater and determine the required length. To do this, calculate heat losses balcony A lot of heat energy comes out through window openings, and therefore it is quite difficult to achieve a temperature of +20–23 degrees, especially in winter. Therefore, experts advise installing the heating system in heating mode.

Before installing the floor, the balcony is insulated. Ideally, heating mats, cable or infrared film should be heated to +26 degrees. This temperature is suitable for parquet floors.

If you use tile, marble or other material as a top covering, it is necessary that the cable is heated to a temperature of +28–31 degrees.

As a rule, loggias require 160–180 W per m2 for heating and 200–220 W per m2 for main heating. Taking into account these recommendations, you can make calculations and determine what the ideal length of the cable should be, what the laying step should be, and how powerful the heating system is.

Let's assume the area of the loggia is 2 m2. The floor is tiled, no screeds are expected. Let's take a heating mode that requires 200 W per m2 and calculate the heating area using the formula:

Sgr = Stot - Spr

Here Spr is the area occupied by furniture.

Let's assume the area occupied by furniture is 0.5 m2. Then Sgr = 2 – 0.5 = 1.5.

In this case, the system power should be 1.5 * 200 = 300 W per m 2. If a screed is not intended, use thin cables that can be completely embedded in a layer of tile adhesive. Suitable system you can select from tables that describe the technical parameters of the equipment.

h = (Sgr * 100) / Lcab

Here: h - laying step; Lcable - cable length in meters. You need to substitute the values into the formula and get the result.

If you are laying cables or heating mats, remember that you need to retreat 10 cm from the walls.

How to make a heated floor on a balcony with your own hands

Option No. 1. Water system.

How to install heated flooring on a balcony? Technically, installing a heated floor on a balcony is as simple as installing a cable system. A concrete screed can be used to install the structure. The system can also be mounted on a dry surface - between wooden joists.

An excellent option is a concrete screed, since this material is an excellent heat accumulator. If you are going to start a long process related to obtaining a permit and spend money on installation, then it is better to do it reliably and professionally.

Pay attention! First, they always install windows and insulate walls, and only then lay floors, including warm ones. But the installation of floors always precedes the finishing of walls. The same applies to ceiling work.

It is necessary that the base, that is, directly reinforced concrete slab, was perfectly smooth. Remember: on balconies and loggias, from the very beginning the slab is tilted slightly towards the street so that water drains.

This essentially does not create any obstacles for installation. The main thing is that the slab must be perfectly flat, without depressions or bumps. Although, if you still need to fill the screed for leveling, it is better to immediately place it horizontally.

After the lower concrete base has been leveled, waterproofing is laid over it. The floor can be covered with a layer of technical polyethylene - it is inexpensive and takes a minimum of time. When installing a heated floor on a balcony, waterproofing is always installed facing the wall. The film should be positioned higher than the finished floor covering.

Next, thermal insulation is made. It is not recommended to use mineral wool insulation on the balcony. They get wet, and therefore they need additional protection. On walls and ceilings it is better to use foam boards with a thickness of 50 mm and a density of 25 kg/m 3.

Now the floor. It doesn't matter what material or type you install the final covering. To date, the most optimal and practical option The insulation is extruded polystyrene foam in slabs 30–50 mm thick. Popularly, this material is most often called penoplex.

Of course, the cost of extruded polystyrene foam is three times higher than the price of polystyrene foam and 5 times higher than the cost of expanded clay. But think for yourself, balconies and loggias are usually very small. Most likely, for the sake of the quality and reliability of the repair of this small room additional funds may be allocated.

Extruded polystyrene foam boards are a fairly durable insulation material. Today, this particular material is used to insulate airfield runways and toll highways. That is, extruded polystyrene foam can withstand a screed of any weight. The main thing is that the base is level and the load is evenly distributed over the plane.

Piping can be fixed directly to extruded polystyrene foam boards. For this they take flexible pipe made of metal-plastic with a cross-section of up to 22 mm. It is important that it be solid, since screed cannot be poured into a structure with adapters.

The heated water floor on the balcony is placed in the shape of a snail or snake. The last option is used most often in Russia, since most of our balconies are elongated.

Rigid plastic clamps can be used to secure the pipe to the slab. They are installed on top of the pipe and placed directly into the penoplex. Also, a reinforcing mesh made of metal with a wire cross-section of up to 5 mm is often placed under the screed and pipes are tied to it using soft plastic clamps.

In those places where the pipework enters and exits the concrete screed, plastic or metal corrugation is put on the pipes. This is done in order to eliminate the risk of accidental pipe fracture.

Important! Before pouring the concrete screed, the “warm floor” system must be connected and tested. That is, the pipes must stand for at least 24 hours under pressure that is twice that specified by the design.

The concrete screed itself under a warm water floor is poured over the insulation with a layer of 50 mm. The pipe must not be placed closer than 50 mm to the wall. In this case, a distance of 100–150 mm must be maintained between the turns of the pipe. The pipes, of course, should not intersect.

Before pouring the concrete screed, it is necessary to attach a 10 mm thick tape made of polyethylene foam (penofol) around the perimeter of the balcony. This element will provide a damping gap during heating and expansion of the concrete monolithic structure.

The easiest way is to use self-leveling compounds. But they have a significant disadvantage - a high price. Therefore, many people install beacons and pour screed over them based on a simple cement-sand mortar. Moreover, taking into account the fact that it is very easy to install beacons on self-tapping screws for insulation. After 7 days you can already step on the screed, and after 28 days you can begin finishing cladding.

It is much easier to install a water-heated floor on the balcony between the joists. If the concrete base is crooked, you may not need to make a bottom leveling screed. All you have to do is place the wedges under the joists.

The frequency of laying lags cannot exceed 30–40 cm. The height of such lathing is made around 70 mm. Here, 50 mm of insulation and 20 mm of the thickness of the metal-plastic pipe are taken into account. Of course, a polyethylene layer is laid under the sheathing.

Here you can avoid using extruded polystyrene foam boards. Simple polystyrene foam is also suitable, since the entire load will fall not on the insulation, but on the logs. The insulating material itself is laid between the joists. In this case, the gaps are blown in using polyurethane foam.

To lay the pipe routing, you will need to cut a series of 20x20 mm grooves in the joists using a hacksaw and chisel, according to the thickness of the pipe. But for styling finishing cladding(linoleum, laminate, carpet) on top you need to lay sheets of plywood or OSB with a thickness of 10 mm.

The dry method of laying a water-heated floor system has a visible advantage: such a structure is easy to repair. But its efficiency and heat transfer rates are lower than those of a structure with a concrete screed.

Option number 2. Electric heated floors.

Electric underfloor heating is a system based on a heating cable. Until relatively recently, specialists used twin heating cables with a diameter of up to 55 mm during installation. The entire route was secured to the insulation individually using metal brackets.

The cable was also laid in the shape of a snake. The coils were spaced at a distance of about 100–150 mm, as in the case of the water system.

Electrical cable mats are in great demand today. Essentially, this is the same cable, only twice as thin. It is attached to a fiberglass mesh. The cost of such mats is not much higher, but they are much easier to attach to the base.

Installation of thermal and waterproofing is carried out according to the same principle as in the case of a water system. It is best to pour concrete screed under all finishing coatings - the only exception is floor coverings. tiles.

The thickness of this screed is at least 20 mm. Experts advise laying a metal reinforcing mesh under the mats to protect the cable from accidental cracks. Fixing the mats on the reinforcement is an unnecessary action. They will remain in place anyway.

If tiles are used as a finishing coating, they are laid directly on the mats. Construction adhesive is used for this. Ceresit CT83 is ideal if you are using extruded polystyrene foam boards underneath as it is designed specifically for this material. The thickness of the adhesive layer should not be less than 10 mm. It is applied to the tile and base using a comb spatula.

Any electric floor must be equipped with a control unit consisting of a temperature sensor and a control panel itself. The sensor itself is installed between the turns of the cable and a wire is brought out from it into the control panel.

The control panel is mounted nearby on the wall in a box similar to that used for an outlet or switch. To lay the wires, a groove is punched in the wall.

Important! If you are going to install an electrical cable in a screed, you need to select the cable power at the rate of 200 W per 1 m² of heated floor. If you are laying mats under tiles, 140–160 W per 1 m² is sufficient.

Electric heated floors, regardless of the type of system, are always mounted on work surface balcony or loggia. That is, there is no need to install it under cabinets or in hard-to-reach places.

If you have sufficient theoretical skills and a good understanding of how to connect wires, you can certainly construct a system from individual parts. Today the construction market offers ready-made kits with detailed instructions and all necessary elements, including small fittings and insulation materials.

Option No. 3. Infrared system.

This system is the most common today. It is so easy to install that even a beginner can handle it in just a few hours.

Some experts do not advise installing powerful thermal insulation under an infrared heated floor on a balcony, explaining this by the fact that the principle of operation of the system is completely different. Yes, that's true, but with the heaters off, your floors will just be icy. Therefore, it is better to put slabs of extruded polystyrene foam and free yourself from unnecessary problems.

Before the installation of thermal insulation, any underfloor heating system is installed according to a similar scheme. Before laying the infrared film directly, the slabs of extruded polystyrene foam are completely covered with foil isolon - a foamed polymer sheet covered with foil.

Next, all joints of the fabric are carefully taped with foil tape. In those places where the film is connected, holes are cut out under the contacts, as well as under the temperature sensor in the isolon, using a knife so that the thickness of the entire coating is the same.

The film is cut along the outlined dotted lines, laid on the isolon and along parallel circuit connected to the control panel. The contacts are crimped and protected with pieces of bitumen insulation. Installation of the temperature sensor and control panel is carried out in the same way as when installing cable mats.

To protect the infrared film, a layer of polyethylene is laid. IN in this case You no longer need to glue the joints - just make a 100 mm overlap.

According to the developers, almost any floor covering, with the exception of tiles, can be laid on such a film. As a rule, they use infrared heated floors on the balcony under laminate or parquet.

Apartment owners are wondering how to make a warm floor on a loggia or balcony? Everything is quite simple. The technology for installing heating elements is not much different from the installation diagram inside an apartment. To install a heated floor on the balcony, you can choose either an electric system or a water system from centralized heating.

Electric cable heated floor

Cable heated floors are a cost-effective and efficient option for a balcony or loggia. This system ensures uniform heating of the entire surface. The heating intensity is adjusted using a thermostat. It is installed on the nearest wall and receives all information using a temperature sensor.

This scheme is quite effective because it allows you to obtain economical system with minimal electricity consumption. Its significant drawback is the need to pour a thick cement-sand screed, which significantly reduces the height of the room.

Do-it-yourself warm floors on the balcony are installed in the following way:

The foundation is being prepared. Debris is removed, all defects in the form of cracks or significant irregularities are eliminated. Filled if necessary thin layer cement-sand screed.
Roll-type waterproofing is installed. Can be used plastic film or any other material. It will prevent the insulation from getting wet and increase the service life of the entire underfloor heating system. The waterproofing is attached using adhesive tape.
In increments of 0.5 m across the balcony, logs are installed from wooden slats. Anchors or dowels are used to secure them.
The longitudinal slats are being installed. For the standard width of a balcony or loggia, three beams will be enough. They are attached to the crossbars with self-tapping screws. The logs are leveled using mounting wedges.
Insulation – mineral wool, expanded polystyrene – is placed in the resulting space between the joists. It is important to fill the entire area without leaving any gaps or gaps.
Chipboard sheets are laid on the logs. They can be fixed with self-tapping screws. Chipboard is better only works in conditions of high humidity. It is not advisable to replace them with other material. All joints must be sealed using polyurethane foam.
A reinforcing mesh is being laid, which will increase the crack resistance and strength of the screed.
Using plastic clamps, the heating cable is attached to metal rods. It is laid in the shape of a snake with a pitch between turns that corresponds to the power of the heating elements. On average this distance is 10 cm.
The thermostat is being installed. This is best done on a wall inside a living space. To obtain information about the operation of the system, a temperature sensor is placed between the turns in the corrugated tube.
All elements of the system are connected to the thermostat and power is supplied from the network. It is necessary to test the operation of the heated floor and check the operating resistance of the cable. It should not differ from that indicated in the device passport.
A cement-sand screed about 3 cm thick is poured.
The selected floor covering is installed. For balconies or loggias it is best to use ceramic tiles.

Film infrared heated floor

Such an electric heated floor has many advantages, since its installation does not require pouring an additional layer of cement-sand screed. She produces significant load on the balcony slab, which is not always taken into account before its installation. Also, underfloor heating of this type can be installed fairly quickly. Considering the small area of the balcony, the whole complex of work, including installation of tiles or other covering, will take no more than 3-4 hours.

Warm floor on the loggia

Do-it-yourself warm floor on the balcony using a thin film is installed as follows:

Installation of heated floors using centralized heating

Water heated floors have many advantages, including high efficiency, economy and reliability. There is no need to use electricity to operate this system. It is enough just to connect the tubes inside the structure to the centralized heating or boiler (gas, electric or any other).

Water heated floors are quite cheap, but their installation may be difficult for some. During installation, you must strictly follow the recommendations of specialists in order to create an effective and durable system. Water type underfloor heating is installed in the following way:

After successful testing of the heated floor, the screed is poured, followed by laying a suitable floor covering.

Every year, the number of owners of apartments with balconies, whose plans include year-round use of free space, is increasing exponentially. In most cases, they are faced with the question: “How to create comfortable microclimatic conditions in winter and autumn-spring, not only in residential premises, but also where developers have not provided heating radiators?” In this case, we are talking about balconies and loggias. They are especially valued by homeowners if the apartment has a small area. In this case, the loggia can be converted into a bedroom, personal office, winter greenhouse or even a small gym. Another completely justified solution is equipment on the workshop loggia - ease of ventilation, compact dimensions and a large amount of light - all this contributes to the creation favorable conditions for creativity. However, the whole atmosphere will quickly disappear if, in order to go out onto the balcony, you need to look for slippers for a long time, and dust from the balcony constantly gets into the room. In cities where typical apartments are characterized by a small area, homeowners prefer to convert them into living space, which becomes their favorite relaxation room. But in order to turn a balcony or loggia into a full-fledged room, you need to decide on its intended purpose. In the event that you intend to use the balcony for domestic needs, in order to optimally insulate it, you only have to carry out glazing and partial laying of thermal insulation material. But if you plan to convert the balcony into a separate living space or its extension, experts recommend installing a heated floor on the balcony. Next, we will look at the main types of heated floors and installation methods for the most popular options.

Warm floor on the balcony: ways to insulate the balcony

There are several ways to insulate a balcony, and before choosing the most optimal one, you must clearly understand the difference between a balcony and a loggia. Having figured this out, you will understand that it is not practical to insulate the floor on an unglazed balcony. If you plan to turn a balcony into an additional room, first of all, take care of installing the walls, and, in the case of an apartment on the top floor, installing the roof. Only after completing all the above measures can you proceed to insulation. internal space, including gender. If we are talking about a loggia, you need to make sure that there are no cracks or gaps in the windows through which heat will escape.

There are several ways to heat a balcony or loggia:

Use of central heating radiators. Even though this method is effective, in the process of its application it is necessary not to forget about the legal prohibition of installing central heating on the balcony, neglect of which can lead to serious consequences;

Another popular way to insulate a balcony is to install electrical heating devices. Currently, the modern construction market offers consumers electric radiators, electric convectors, electric fireplaces, as well as combined heating devices. Oil radiators are the safest in terms of operation.

Important! Despite the variety of methods for insulating a balcony, in modern conditions the most popular is the installation of a heated floor on the balcony, which can be carried out in several ways, each of which is characterized by its own advantages and disadvantages.

Rules for choosing a heating element: what to look for?

The first thing you need to pay attention to when choosing a heating element is concrete screed thickness. To effectively install a cable heated floor, the thickness of the concrete screed must be at least 5 cm. If the thickness of the concrete screed is less than 5 cm, the most optimal choice You will have an infrared heated floor or a heating system using heating mats. It should be taken into account that if heating mats are installed, the floor height will increase by one centimeter, while infrared heating film is mounted directly under the floor covering.

Flooring material- another factor that you need to pay attention to when choosing a heating element. If you have chosen porcelain stoneware, concrete, tiles or stone as your flooring, experts recommend giving preference to a cable heating system. Coverings made of carpet, laminate, linoleum or PVC are most optimally combined with heated floors equipped with heating mats. Another suitable option for flooring using linoleum, laminate or carpet is infrared heated flooring.

In addition to the above options, there are other methods of installing heated floors that must be taken into account depending on certain conditions. When installing wooden floor coverings, it is important to remember that its thermal conductivity will noticeably decrease compared to floor coverings made from other materials.

How to make a warm floor on the balcony?

Installation of cable heating system

Speaking about the insulation of a balcony, the heated floor in the structure of which performs one of the most important functions, let’s look at how to make a heated floor based on a cable system. In the process installation work, you will most likely encounter difficulties due to limited space and design features premises. Laying the electrical cable, which is the main heating element- one of the most acceptable solutions when installing heated floors. The cable is installed under the finished floor covering, while the thermostat must be left visible - another important element of an electric heated floor, designed to regulate the heating intensity. Setting the most optimal level is done manually and is determined by weather conditions and individual preferences of the owners.

Important! Laying of single- and double-core cable elements is carried out during the installation of the concrete screed. At the same time, it is important to remember the need to lay warm and waterproofing materials, which helps reduce heat loss.

Briefly, the installation of an electric heated floor is as follows:

Leveling the base floor surface;
Laying thermal insulation material, which is the basis for further securing the mounting tape;
Fastening the mounting tape on top of which the heating cable is laid;
Installing the thermostat in a place accessible to you;
Filling the entire floor area with cement-concrete screed;
Laying ceramic tiles.

Installation of water heated floors: brief instructions

Prepare the floor surface. Preparatory activities include leveling the surface followed by marking the room under expansion joints and cleaning the work surface from debris;
Lay down thermal insulation material, the thickness of which does not exceed 30-140 mm;
Carry out installation reinforcing mesh designed to secure the pipeline. To prevent deformation of the material, it is mounted on both sides;
Install the control group and manifold in a cabinet located on the wall;
Fasten the pipeline in a zigzag manner, which means increasing the pitch between the pipes as you move from the wall to the center;
Connect the pipeline to the control system and conduct hydraulic test heating system during the day;
Fill the concrete screed, adding plasticizers to the solution to increase the thermal conductivity of the coating;
Install the finishing coating.

DIY infrared heated floor

Installing an electric infrared floor is not difficult. It is based on film elements that heat the floor covering and do not accumulate heat. At the same time, the installation of the floor covering does not require pouring a concrete screed. Installation of an infrared heated floor requires the installation of high-quality vapor and waterproofing, and in the case of laying laminate, the use of a substrate for the laminate. The floor must be covered with penoplex, on top of which a special thermal film is laid that can emit infrared waves, under the influence of which the furniture and floor covering heat up. In this regard, it is important to remember that the installation of thermal film is not carried out under furniture.

Warm floor on the loggia video

Warm floors on the balcony can be made in 2 versions: electric and water. However, since the second option is used extremely rarely, due to the fact that heating radiators are most often not provided on balconies, we will dwell in more detail on the first option.

In conditions modern life When housing prices are sky-high, you need to save every centimeter of living space. For this reason, many people have the idea to expand living space due to the balcony. But how to do this? It’s very simple, you just need to install a heated floor on the balcony.

Do-it-yourself warm floor on the balcony

Electric heated floors come in the following types:

With heating cable. To ensure a comfortable temperature, you will need approximately 150 W per 1 m² of floor. Next, the cable is poured using a screed, and after it hardens, the floor covering is laid. If you comply with all safety requirements, you can start using the floor after a month.
Floor with infrared heating. Is in the newest way insulation. To install such a floor, select the required width of the coating with a power of 80-220 W. Under the film, on top of the floor, a lavsan of at least 5 mm thickness is laid, and the film is laid on top of it, so that the copper side is at the bottom.
With thin heating mats. This heating is based on electrical cord, attached to a fabric mesh base. This floor is good because it does not require thermal insulation when installing it. The mesh is half a meter wide and varies from 2 to 24 m in length. The heating mats are simply rolled out on the floor, after which the floor is immediately ready for laying tiles.

The best flooring option if you use electric heating is ceramic. The “heated” floor is connected to thermostats, which help maintain the desired temperature.

If, however, you have the opportunity to install a water-heated floor, then it is better, of course, to choose this option. This decision is worth making for a number of reasons, including cost-effectiveness and safety.

Well, that's all about the warm floor on the balcony. But, nevertheless, if you are serious about insulating your balcony, then it is better to consult with a specialist about the most acceptable option and the cost of the work.

How to make a heated floor on a loggia

Everyone loves to drink tea on the loggia, read or just admire the sunset. However, this is all in the summer, but what about in the winter? In winter, even on a glazed and insulated loggia it is difficult to stay because of the cold, and the usable area is simply empty. The most effective way to solve this problem is to install a heated floor on the loggia.

Just like on a balcony, it is quite difficult to install a water-type heated floor on a loggia. For this reason, the warm floor on the loggia in nine cases out of ten is a warm floor electric type. In this type of field, a wire is used that serves as a heating element, which is completely filled with cement screed. Only the device for adjusting the heating intensity remains outside.

Installation of heated floors on the loggia

Installing such a floor is quite simple. First of all, a layer of thermal insulation is laid on top of the leveled surface, on top of which a mounting tape is attached. A conductive cord is laid on top of the mounting tape, and the thermostat is installed on the wall, where it can be easily reached.

A cement screed is poured over this entire structure. Ceramic tiles are laid on the loggia floor. You can use laminate or parquet, but firstly it turns out to be more expensive, and secondly, the tiles better meet the requirements of thermal conductivity and thanks to it the warm floor will be heated in 10-20 minutes.

Moreover, thanks modern technologies, you can install a heated floor on a loggia without even using a screed, thereby reducing the load on the floors. This is done using penoplex and a special thin thermal film. And as a floor covering, in this case a laminate with a backing is used.

Since such a floor has high heat transfer and relatively low energy costs, it is the most rational system to eliminate window frost and humidity in winter. And in general, a warm floor will help ensure coziness and comfort on the loggia even in the most severe frosts.

How to make a heated floor on a balcony with your own hands

If you expanded or simply glazed the balcony, then most likely you hoped to use it as a small extra room. But in winter it is cool on the balcony. How to bring heat to the balcony? The balcony can be heated by installing a radiator there, but it is better to install a warm floor on the balcony. But how to make a warm floor on the balcony? This is what we will talk about.

To begin with, it’s worth saying that since enough has already been said about installing an electric floor, let’s assume that somewhere near the balcony you have a pipe with hot water, and consider the option of installing a water-heated floor. Installing a heated floor on a balcony consists of 3 main stages. Let's look at each one separately:

Preparatory work. First of all, check if the balcony slab is damaged. If the slab is collapsed at the edges or has other defects, this should be corrected with reinforcement and cement mortar. To strengthen the structure, tile adhesive can be added to the solution.
In addition, you will need to level the slab using a screed so that the plane of the balcony is flush with the plane of the room. This point is very important if the warm floor on the balcony is a continuation of the warm floor in the room. But, if the warm floor on the balcony is not connected to the room, then the level balcony slab It can be different, the main thing is even. After leveling, the screed must dry completely, which is at least a week.
Pipe installation. Before laying the pipes, you need to start laying the hydraulic barrier. After which, you can think about thermal insulation. As thermal insulation, you can use a heat reflector, although it is better to use high-density foam plastic. Density indicators are selected based on loads. It is believed that 35th density is quite suitable.

First, you should apply markings along which the pipe will be laid. Since the area is small, we will lay it in a snake rather than a spiral. The interpipe distance is from 15 to 20 cm.

When distributing the brackets, you need to take into account the spacing between them. When the pipe goes straight, the distance between the brackets should be from 50 to 70 cm, and when the pipe turns, the brackets should be installed more densely. Before laying, you can put a soft spring on the pipe, slightly larger in diameter than the pipe itself. This will allow the metal-plastic pipe not to break at bends.

If you are laying metal-plastic pipe, use only the seamless option. It’s better to double-check the seller’s words and see for yourself the quality of the material. To do this, simply cut a little of the tube and remove the layer of plastic on top. The harder it is for you to do this, the more reliable the product. When the plastic layer is removed, you should work on the aluminum pipe, carefully check the metal for the presence of a seam.

The final stage of laying heated floors on the balcony

Now you should pour the cement screed over the entire system. To maximize the heating of the balcony room, ceramic tiles must be laid on top of the dried screed. This material has good thermal conductivity and warms up quickly, while it is better not to use laminate and parquet.
