Secrets floor heating device under the linoleum on the concrete
Despite the great popularity, the best one finish coat to Heated floor, this material is difficult to call. Good insulation properties, changes in the shape and color when exposed to high temperatures, not all of its shortcomings. The probability of emission of harmful substances when heated - this is the main disadvantage of this flooring.
However, if you do not want to see anything on the floor except linoleum, floor heating put under it can be, but not all types. The most suitable types of floor heating in this case is water, and electrical, to which the cable and infrared type.
Mandatory conditions - installation according to the rules and strict observance of temperature regime. There are specific requirements and to the concrete base. It is necessary to prepare so that there is no height differences. It is considered valid if the difference in the area of 2 m² roughness does not exceed 0.2 cm.
Basis requires thorough cleaning followed by applying primer and a waterproofing layer. To balance the expansion that occurs during sex, across the bottom wall around the perimeter of the compensation decorate ribbon of polyethylene foam.
Since many brands of linoleum are equipped with a substrate that can independently act as a heater, not all types will be able to skip the heat rays warms systems
What linoleum choose?
Linoleum is present on the market, despite the visual similarity is different according to different parameters. He may have different thickness, composition, structure, and reinforcing base, if present, may differ by type.
When choosing linoleum, you need to correctly use the information encoded in the labeling applied by the manufacturer. It is encrypted information about the composition of this type of coverage, the possibility of its heating, the maximum allowable temperature.
Right should be excluded from his list of material, which is based on Phenol polymer, ie, Alkyd linoleum. He is maloteploprovodnym coating, eventually changing its size. For device underfloor these properties are a great disadvantage.
Unsuitable option is koloksilinovy and linoleum on the basis of nitrocellulose, having high flammability. Although the composition of the linoleum and antipirenbornaya acid present, some fire hazard-reducing material under it is not advised to arrange a heated floor.
If the selected linoleum recommended by the manufacturer for styling paired with underfloor heating, it is attended by such approvals marking, as in the photo
Rubber linoleum Relin and should not be considered. Furthermore, it is a good thermal insulator, and heated from below, the material may change the structure. This will quickly lead to its destruction.
PVC linoleum with good strength and hygienic characteristics for underfloor heating is suitable more than any other species. A more expensive option - natural linoleum (marmolium), created on the basis of the safety components.
In its structure there are jute fabric, natural dyes and other natural components. The main rule: heat the linoleum PVC only to 30⁰, and natural - to 27⁰ maximum.
When choosing PVC linoleum for finishing floor heating, it is better not to consider his view of consumer and commercial or semi-commercial, as the stronger. Teploizoliruyuschuya basis for this purpose is not necessary, it will only reduce the effectiveness of the system.
More suitable material or even without a base or with a very thin tissue substrate. First time vinyl linoleum in tandem with the heating cable may produce an unpleasant smell, but then it disappears.
concrete floor device
Immediately solve the problems associated with installation of "warm floor" system on a concrete foundation, and choose the appropriate type of linoleum can be when rough floor already exists. If instead there is only an old rotten wooden base or simply the ground, you need to take the device of concrete floor.
The process consists of several stages:
- the old floor, if any disassembly;
- alignment framework;
- cushion device;
- arrangement of the insulation layer;
- preparation and pouring concrete solution.
soil Alignment is performed by shovel. Then begin to create a pillow. For this poured gravel or small pieces of brick, slate broken at a height of about 50 mm. All this is a little ram.
The perimeter of the room is closed the foam sheet having a thickness of 20 - 50 mm. He will also serve as formwork, and at the same time balance the thermal expansion of the concrete base. This layer of clean sand is poured - 10 centimeters.
This is followed by laying the second type of insulation. Most suitable for this extruded polystyrenePreferably Penoplex mark, which is discharged in the form of rigid plates of 50 mm thick.
Polystyrene or penoplex resistant to temperature changes, ecological, tolerates a compressive load, water-resistant, durable
Sheets manufacturer has provided a tool joint, so when laying leave no gaps. When installing the need to monitor the horizontal position using a spirit level. Waterproofing is not needed, because material is extremely resistant to moisture.
The next stage - the preparation of the solution. The optimum ratio of components - 1 part cement, a sand twice and three times longer dropouts. As a result, the solution should not be flowing, but not overly thick.
To not overlap much load in concrete mortar is introduced rovniteli and lightweight fillers. Before pouring the solution put beacons at the walls, pull the cord between them. Focusing on these labels, place the intermediate rail marker.
Cement composition traditional base 10 mm weighs about 20 kg, so it can be used Only in the case where a warm floor or when the suit under him on the first floor of the house is very strong overlap
The surface is moistened and spread on it the solution between beacons and level regulation. As the setting surface level. At the end of applied building level to check the levelness. After removed the label, the void is filled with a solution and leave everything to dry completely.
Infrared film on a concrete floor
This version of the floor heating is the most loyal to the linoleum, but a thin film is easily damaged, so the concrete base under it must be perfectly flat. For effective heat transfer infrared heaters need to get this process took place in the same direction.
The same principle operates any other system "warm floor". Unilateral release of heat is only possible when the thermal conductivity of the material in the top and bottom with respect to the heating elements, is fundamentally different.
The heat capacity of the top layer should be significantly higher than the sub-floor. Under these conditions, the efficiency of infrared floor It can reach 97%. In this case, the installation of this system does not introduce any significant adjustments in height space parameters.
Constituent underfloor: a base made of concrete (1), heat-reflecting substrate (2), infrared floor (3) made of polyethylene film (4), the veneer (5), a layer of adhesive (6), linoleum (7)
For laying infrared film on concrete floors must first perform a thermal cutoff assembly. After that, begin to work, preparatory to laying linoleum.
Features of the shielding layer and its installation
The heat shield due to its high reflectivity can reduce the transfer of heat to the concrete floor by an average of 75%. The best option is foil coated with a basis of Dacron.
There are other less expensive metallic materials produced on the basis of polyethylene foam, but they have a thermal conductivity higher, so more will heat loss. A rational approach to this issue provides for the acquisition of electric and thermal insulation system in conjunction with the heating elements.
It is better when it's all released one reputable manufacturer. Quality insulating materials - rational consumption of electricity for heating guarantee. The heat shield is necessary only where the film stacking, but it is better to lay it on the whole area in order to avoid irregularities.
Installation is performed in the following sequence:
- Termopolosy laid on a concrete base, sending reflective side up.
- Connect the individual strips double sided tape.
- Placed between the webs of the temperature sensor and fix it with tape.
- Connect wire sensor and a regulator, protecting them duct or hidden in Stroebe punched into the concrete.
Good quality infrared film and components issued by manufacturers such as Q-term, Lavita, Enerpia, Rexva, noted by many consumers. They have approximately the same specifications, and the difference in cost - feature of the pricing policy of a particular company.
Choice should be made for bandwidth and maximum power. Linoleum optimum power 150 W / m². With this value does not change its coating structure and does not emit harmful substances.
Mounting infrared film
To minimize the number of sections and connection points, strips are placed along the room. Before laying the film is divided into parts. cloth length depends on its width. To meter of film assume the cutting into segments of a length of 7 m, a width of 0.8 m - 10, and the half-meter blade for termopolosy maximum length of 13 m.
Perform better wire connection blocks MF - 3.1 x 1.5, that will provide the minimum heating them in the case of peak load wound 10 A. For powering the thermostat used VVGng cable. Units are individually connected each to the thermostat or the nearest junction boxes
Competent alignment - indent the walls of 200 mm, the gap between the strips 30 to 50 mm, the contacts are as close to the wall on which the thermostat is placed.
Under no circumstances should there be overlaps. Termopolotno, using masking tape, secured to the heat shield. Cuts on the sides and fixed using screws or staples.
At the edge of the copper film strips, in close proximity to the thermostat, wear tips. the power cord is connected to them. It is inserted into the tip and press down with pliers. Sectioned, and the point of connection of wires on both sides are isolated bitumen tape. Strips connected in parallel.
On completion of laying, is connected to the thermostat and temperature sensor wires connecting these elements with infrared film. Check the correctness of connections made, then tested the system on a concrete base.
If all goes according to plan, teplopolotno cover with plastic wrap, making an overlap of 20 cm, and then fix the waterproofing tape.
Laying linoleum top IR system
This material is not very rigid, so that during walking does not deform the heating elements beneath it requires planarization layer. Make it from plywood with water-resistant properties of a thickness of about 0.8 cm.
That when fixing the veneers do not damage the film, it is necessary to mount hit the technological gaps provided between the heating elements or on the edges of the film. fixing step is about 150 mm.
The substrate of plywood under the linoleum flooring will compensate for minor irregularities and cracks in the concrete base and topcoat will stay longer
When laying between the walls and be left plywood sheets compensating clearances 0.1 - 0.2 cm. Subsequently, they are filled with moisture-resistant sealant. After the sealant has dried, removed from the entire surface vacuumed dust. Further, plywood primed give the primer to dry and lay linoleum in the usual way.
Cable electric field
When cabling laying the concrete floor first leveled and then placed on it, or a special reinforcing mesh straps. She placed the cable is fixed, then pour the concrete mixture. When the screed is dry, lay linoleum.
Before all this work is determined by the cable length. If it has a 15 cm step, one loop will take approximately 25 cm.
With the known area of the premises, which will have underfloor heating installation, calculate the number of turns, the branches of the cable and its length overall. To this segment is added to the value coming from the coupler to the wall where is placed the thermostat.
When calculating the area covered underfloor of its total value subtracted binding five-inch offset from the walls, the space occupied by furniture. On clean concrete floor insulation is applied to its entire area. Glued joints foiled tape.
On the site, designated for the installation of underfloor heating, paving the metal tape to secure the cable so that it will last for the whole area. On the wall is allocated to the regulator. Then doing a mounting hole for the installation and pave Stroebe box. After mounting the regulator is attached to it a temperature sensor.
Wire from heating elements to the controller paving temperature. This also fed temperature sensor mounted in the bellows tube, the cable from the main power source
The heating cable is laid, starting from the edge of the corrugated tube at which the sleeve end of the cable should be present. Electric floor assembly produced by adhering calculation step as a snake, is laid flat threads, excluding creases cornering. Hooks fix the heating cable, available on the previously laid metal strip.
Strongly tighten it should not be, but still the cable should be as straightforward. Step calculated by multiplying the heated area 100 and then dividing the result by the length of the cable.
After a short sampling system pour 5-cm layer of screed. When it has dried, mounted topcoat.
The coating on the water floor
The water heating system is combined with a concrete base. But here's the crowning coating of linoleum - not the best choice in this case. Yet a certain kind of lay linoleum as possible. The main thing that he was not fat and low quality.
Scheme should consider in advance. In a prepared foundation waterproofing layer stack. Along the seams between the strips glued strips of adhesive tape. On top of plate placed thermal insulation, which fasten special fasteners - "fungi", under which the pre-drilled holes.
The collector is lowering the temperature of water entering the system, since the It is mixed with cold coolant heated. In addition, this device is responsible for the regulation of the coolant volume supplied separately in each circuit
Using the same "fungi" is fixed to the insulant reinforcing mesh, performing overlap, one cell size, and using plastic ties for connecting the individual bands. On the wall of the manifold set, then it is connected to the pipe. Compensate for thermal expansion of the floor, by sticking to the walls surrounding it, a special tape.
Thereafter, the tube can be fixed, forming the heating circuit, on the reinforcing mesh, and then connect them to a collector. A better way of fixing floor heating pipes - application specially designed for this assembly system with click-clamps or clips rails. It is fixed to a concrete base before laying pipes.
Such a system tubes attachment warrant the accuracy of pitch adjustment, secure fit that prevents shifting while pouring their ties and its hardening
To start casting ties of water the floorPipes must be filled with water, and on the floor and install beacons align them on the laser level. A coupler, a minimum thickness of 40 mm, is filled with the same rules as in the apparatus of other kinds of floor heating.
linoleum floor clearance can be run no earlier than a month. During this time cement attains the necessary strength. Up to this point it is impossible to start up the radiant floor heating.
