A warm floor under the linoleum on the wooden floor

trend using modern heating systems is gaining momentum.More and more owners of houses and apartments for repairs or upgrades prefer not to dwell on the classical scheme with radiators, and establish a more effective, invisible, does not infringe any interior style, cost-effective system.One of the variants of this innovative campaign became heated floor surfaces - the convenience and comfort of the heating principle has proven operating practices.

If uniformly heat the floor surface, the warm air distribution throughout the volume is much faster and smarter, and in this case - does not create such a nasty, "skvozyaschih legs," his horizontal convective movements.And moving on warm surfaces in the home or even barefoot shoes - much nicer and safer from the point of view of probability make colds.And it is - especially important when children are growing up in a family.

warm floor under the linoleum on the wooden floor

In short, the advantages of "warm floors" are increasingly outweigh the quite

understandable fear of the hosts to communicate with large-scale construction work.Interested homeowners are beginning to search for the most suitable options with "minimal losses", so as to avoid the complete dismantling of the old coating, and at the same time achieve high quality surface heating and, at the same time, making the change in the interior design.So, certainly, many of them is the question whether it is possible to mount a warm floor under the linoleum on the wooden floor.

turns out that it is quite feasible, and - even in several ways.

Modern construction technologies offer more effective schemes of floor heating surface using heat coolant energy circulating in the circuits of battery or, more rarely, central heating system, orusing as a source of AC power.Different heating systems require the installation and features of each of them, as well as recommended for the specific conditions of finish flooring.For convenience, the information is presented below in tabular form:

Please note that the vast majority of systems "warm floor" for efficient operation of the closing means of the cable or pipe loop cement-sand screed - it not only becomes the basis for floor finish coating, but also plays a critical role thermal energy storage.In the case of ceramic tiles, it becomes in itself a capacious heat accumulator, and in this case it is possible to resort to a thin layer casting solution samorazravnivayuschegosya or tile adhesive.

But linoleum such a simplistic approach is hardly possible.But the full screed on a wooden floor - that's the whole problem.No, of course, there are similar technologies - after appropriate training screed is poured and the wooden base, but often this is not possible, trudnoispolnimym or totally rational:

  • Any tie (but need not less than 50 mm thickness) significantly raise the level of the floor,and this is without taking into account the future of the topcoat.Not in any room, you can go for it, even more so - in a not too high ceilings standard urban apartments.
  • screed - it's always more, very considerable pressure on the overlap.There are situations, when it is poured from the resort you can not just inconsistency concerns the planned loads possibilities of building structures.If you look, even the 50 mm layer of concrete will give additional force of about 300 kg per square meter.Pour this tie while creating a warm floor system, for example, on the balcony - very risky.
  • Sometimes the fore considerations undeliverable solution to the place of work and the great complexity of its preparation in place.It is necessary to take into account the transport and handling costs - lead and pick up on a high floor of heavy construction materials also results in a costly exercise.In addition, not everyone wants to plant in his apartment when the inevitable works cement mud.
  • Maybe so that the owners simply do not want to part with quality, reliable and warm wooden floors.In their plans - just make it an artificial heating and change the "scenery."Naturally, they are not going to fill the screed.

It is for these cases fit the technology of "dry", "warm floor" system installation.And there is even the opportunity to choose between water and electric heating.The publication will tell about the technology of laying and water, and an infrared "warm floor" to the interested reader to make an informed, the most satisfied with his choice.

Prepare wooden subfloors to work

No matter which way the floor heating is selected, basic wooden base requires some training.This is especially important if the work will be conducted on a fairly old, has served as a lot of the wooden floor.

First, it should carry out a thorough audit of the entire surface, including under load, to identify possible locations foundation instability.If some parts of the floor "play" board, you will have to dismantle them, to get to the causes of this instability = spine.Rather, it lies in the deterioration - podgnivanii, cracking, subsidence lag.All suspicious items require unconditional repair or even replacement.

The first step is to carefully inspect and, if necessary , repair the wooden floor

All items should be treated with antiseptic floor impregnation

It is possible that among the floorboards there are defective, requiring the replacement of parts.

Be sure to get rid of the cracks and gaps between the floorboards - you may need them "bulkhead" and reinstall.Narrow cracks can be repaired a special putty for wood.

Cracks between the floorboards is recommended to close up filler

slits between the boards is recommended to seal the filler

level differences can not be excluded on the old floor between adjacent floorboards or due to repeated staining and subsequent uneven paint peeling.It is also necessary to take care, after spending the alignment with the help of the planer, or even better - by completely sanding the entire surface.This is especially important if the planned installation of infrared film system - is unacceptable even minor level differences.

The uneven surface of the wooden floor should be or scrape ...

can solve the problem in a different way - to lay the entire surface of plywood or OSB sheets, fitted tightly them to each other, and then close up the gap with putty.

In any case, to complete the preparation of the wooden base should be careful surface treatment impregnated antiseptic action.Very often such a treatment and at the same time increases the resistance of wood to the fire.

further work transferred only after complete absorption and drying of the primer composition.

neglect the preparatory work should not be - the system "warm floor" good hosts planned with the hope of long-term use, and remove it from the base of the wooden blemishes will be very expensive.

Water "warm floor" on the wooden base

First of all you need to make an important point.water "warm floor" system is efficient and economical, though somewhat difficult to install.However, it is more suitable for autonomous heating systems (except systems with solid fuel boilers - here it is not economically justified).But before the masters of the apartments are heated with central heating, it may be a number of problems and, as a purely technological and administrative nature.Do not act rashly - kindly consider all «pro» and «contra».

snapshot whether the connection "warm floor" is possible for the central heating system?

Yes, it can be implemented in compliance with certain technical requirements and implementation of the necessary administrative approvals.Read more about the features connection "warm floor" heating system to - in a special publication of our portal.

«Classical" scheme "warm floor" suggests a layer of insulation to heat did not go for nothing unnecessary heating floors, and powerful, accumulating heat and transfers it from the pipe circuit of the floor surface, a layer of screed.

In the case of a wooden base with a special thermal insulation problems arise - a layer of insulation, if necessary, easy to be placed between the joists under the floor surface.But with the heat transfer issue is more acute.If you simply place a tube open at the finish surface, the layer of air to play the role of an insulator, and heat will be very inefficient.Simply put the tube into the slots - not a solution either, as the heat and thermal conductivity of wood - are low, and the surface also will not receive the full heat.In order to ensure an acceptable level of heat transfer is usually a special heat exchangers are used (or otherwise - heat-spreading) of the plate, the profile of which is designed for a tight tube placement in it, ensuring maximum contact area for heat transfer to the metal surface, and already from it - finish.

Thus, these plates perform the dual function - to contribute to the stable fixation of the pipe loop and provide efficient heat transfer.They are made of galvanized steel, aluminum, copper rarely come across.

  • If you intend to installation water loop on a flat surface of the floor, and there is no possibility to resort to milling, it can be simply mounted on a wooden base of the corresponding section of the rack (for example, for a tube 16 mm - 20 mm thick).An example of this approach is shown in the table below.

Laying of floor heating circuits using rails and the heat transfer plates

p2 At junction floor and walls around the perimeter of the room, it is recommended to lay a damper elastic band.
It compensates for possible thermal expansion of coverage overlaps "noisy channel".
In addition, it will be much easier to obscure the plywood under the linoleum - will immediately create the necessary clearance.
