Radiant floor with their hands
Imagine a comfortable bath in the adoption ofa heated building on a cold winter evening. Like all good, but after the end of this relaxing procedure, the person puts his feet on the cold tile and "falls from heaven to earth." Yes, now pleasurable sensations fade into the background, you need to wear warm socks and shoe slippers. Moreover, a similar situation applies not only to the floor bathroom, but also the kitchen, bedrooms and other rooms. Even in a warm room it can often be noted that like the body feels well, but freeze up. Radiant floor solves this problem in the best way, so he and the subject of this publication.

Underfloor heating - increased comfort
Even 15 years ago water underfloor heating causedsurprise and bewilderment in people. Just a man and in a wonderful dream can not imagine that you can walk barefoot on the floor having fun, and the kids can romp and play on the floor in the winter time of the year, while the parents are perfectly quiet - the child does not catch a cold. Then, thinking was quite different, people carefully littered the floors and carpets wore slippers or woolen socks.
Today, this relic of the past can be forgotten and"Look into the eyes" progress and new technologies. Plus, anyone can mount in your abode warm water floor with their hands and enjoy its advantages to the full.
Why do feet always cold?
What is heat? This form of energy is necessary not only to human life but also for a full existence. The reason for freezing a human leg, which is conveniently located in the chair is the wrong distribution of the energy in the room, which is heated, for example, conventional radiators. If you remember high school physics lessons, we can say that the flow of air circulating in the thermal impact on the following principle: a warm air stream is heated by radiators and rises to the ceiling, then partially cooled and has already moved to the floor. Here in this point, that the air has been heated to a temperature of 26 degrees, and it has dropped down to 18 mark. This distribution does not quite match the physiological needs of man.
Heating elements create a warm floorjust at the surface of the "comfort zone": + 22-24 C, and at head level, the very air is a little cooler, around 18. Such a temperature distribution is ideal for a person, so warm water floor gets very positive reviews, it's wonderful feeling, comfort and modern attitude to life.
Advantages of warm water floor
This system has a lot of positive aspects, we would like to mention the most important.
Ease of additional heating
Well, that in our time the radiator is notthe only source of heating. For example, the heating season is over or not yet started, and on the street, respectively, and in the room is cold. What to do? Just dress warmly, with the head to wrap up in a blanket and forbid children to play on the floor. Warm water floor to cope with this problem in the great man himself decides to heat in the house must be either cool.
This independent heating system createsa favorable atmosphere in the room, much better than the convective heating appliances. heating temperature is controlled at will in every room, so cold and too overheated zones in the house will not be.
Another plus in the direction of water underfloor heating -the temperature between day and night time of day, that is, with the help of modern sensor temperature is maintained automatically. A limited air circulation reduces the amount of dust rising up.
Economy - an important argument
To provide the ideal temperature in the house,apartment, office floor warm water has no analogues and competitors. The main element of the system - the pipe, are stacked inside the structure. The heated water circulating in the system, the heat spreads evenly, then overheated and slightly warmed plots there, which is not the radiator heating system. Save energy by creating optimal temperature characteristics, but still it can be reduced a couple of degrees and feel great.
Freedom of design and architecture
Fully concealed system and underfloor heatingabsence of visible surface heating elements opens up a huge opportunity for an acceptable interior decoration (in the sense of arrangement of furniture) to free space was larger. As well as pleasing to the eye window without encumbering heavy radiator. Stone and ceramic flooring can be easily planned, because they will not be cold and unpleasant to the touch.
The design "benefits of civilization"
warm water floor unit is a kind of layered structure, which is called "floor pie":
- Base - a wooden subfloor or concrete slab;
- Waterproofing layer (sometimes it may be supplemented by the damper tape around the perimeter of the room);
- Heat-insulating layer, which prevents the penetration of heat from the system of pipes in the concrete foundation. And it reflects the heat upwards, towards the floor covering;
- Pipe system;
- Bearing stratum. It can be a concrete screed (in most cases) or dry screed made of water-resistant gipsovolokonnyh sheets;
- Finishing coat.
Important: the structural thickness generally varies between 70-150 mm. And it depends on the diameter of the pipe, the thickness of the insulation layer and the power of the most ties.
can be performed in three variants By design the device heated floors water with his own hands:
- Concrete. When installing this type of floor or polypropylene plastic pipes immersed with cement-sand screed. It was she, and serves as a heat spreader.
- Wooden systems - and aluminum heat-reflective plates and pipes with coolant stacked or chipboard, or between the rails.
- Polystyrene. This system involves the laying of water (non-metallic) pipes on polystyrene plates.
The main components of the water floor
- Diagram of the water floor heating has the following form:Pipeline - the main element of the system, the coolant moves through it, it heats the pipe walls, which give the surface its heat to the surrounding. Typically, most for warm water floor tube used metal-polymer, ie metal-plastic. Although it should be noted the fact that in recent years have become popular pipe PEX cross-linked polyethylene.
- Damper tape. It is not used in all cases, but its use is necessary for the installation of floor heating with concrete screed. This foam tape (thickness 1.2 cm), which is glued around the room. When the floor is heated, expanded concrete screed, the main task of damping tapes - by compression to ensure the integrity of the coating (tiles, screeds, marble), and it does not allow the appearance of cracks.
- Heat coating is necessary in order tothermal energy heats only the outer surface of the floor. In general, the coating is applied with a mesh-reinforced intended for fastening pipes.
- The plasticizer prevents the formation of cracks in the screed. It is added to concrete, resulting in altered properties of the concrete, it becomes resistant to temperature change indicators.
- The collector is responsible for the connection of the water floor heating in the heating system itself. Adjustable and uniform distribution of the coolant - collector function.
- Manifold cabinet - the location of the collector.
Mats - thermal insulation material
As has been said, on a concrete foundationshould be laid heat insulating material. Typically, in a modern building used mats for water floor heating polystyrene and foil can be used option for even greater efficiency. An ideal solution because the foil tends to reflect infrared radiation toward the floor surface (working), thus it prevents excessive heating of the substrate.
Ideally, the mats can be used with clamps,which are special equipment for floor heating. The benefits of these huge: ease of installation and a significant reduction of time of work. However, there have mats and disadvantage - the high price.
Note: these plates are made from a very dense polystyrene having a high mechanical strength. So, mats for a long time retain their shape, size.
Insulation mats are laminated in the film coating, that is not laminated.
How to make a concrete radiant floor heating
This option is the most common, but beforehow to make a radiant floor heating, it is necessary to draw attention to an important point: room to accommodate all the "cake" layers should have a reserve adjustment.
Important: if you do not take into account Finish flooring, the reserve should be 85 mm.
Creating a warm water floor with their handstask quite difficult, but still doable. To do this, you must first create a project and calculate the underfloor heating water (here the value will need floor space, its size).
You should also mention that the laying of the water the floor more rational in private homes rather than apartments. The fact that the connection to the central heating pipe smoking.
The first stage - collector group
Maybe it sounds a bit strange, but installationwater underfloor heating starts from the walls. At this stage, you need to choose a location closer to the center of the room. This is a cabinet for collectors, it can be bought in the construction market. This cabinet is installed usually in close proximity to the floor surface. For this operation will need a hammer, a chisel, and physical work.
After the installation of the cabinet to the collectorStarts flow and return pipe. The first deals with the supply of coolant, it contains inside the hot water that comes from the boiler. The second performs the opposite function: collects water that has passed on the heating system and to give the screed of the energy. This water is again sent to the boiler, and it is heated again in the supply pipe. The circulation pump provides a continuous flow of water.
But still go back to the cabinet. On each pipe to install shut-off valves. What are they needed for? Quite simply, if you suddenly will be a need to remove the room from the heating system (repair or savings), the rest of the house will not be affected and will function as before. Then you will only need to close these valves and all.
Important: The plastic pipe and a metal gate connected to a compression fitting.
Then, a collector is connected to the valve. Because in the long run it is a piece of pipe with a few taps, then a logical question arises: what is connected to the output? In the first case, you can use the plug and place a better splitter, on the one hand - the drain valve, on the other - air vent. When the cabinet assembly, you can switch on the heated floor.
The second stage - the preparation of the surface
Paul cleared of debris and the estimated horizontal surface. Certainly a perfect evenness of speech does not go, but the difference would have to align to a few centimeters.
Important: ignoring this advice, you can end up with a non-uniform heating of the floor.
On the level floor waterproofing film unfolds. This is done in order to prevent absorption of moisture.
Further along the perimeter of the room on the walls of gluedthe so-called damping tape. it resembles an adhesive tape, so no problems with the bonding does not occur in its design. Typically, a tape height of 10-15 cm, overlapping layer of screed and insulation. After the end of the tape cut off the excess.
Laying insulation - the next step. Since the heat loss through the floor can be 20%, it is advisable not to save on heat insulator, it will pay for itself in the near future. As a heater can be used extruded polystyrene, mineral wool, cork technical or specially made mats (about them already mentioned).
The third stage - laying pipes
pipe fasteners can be accomplished in severalways. For example, an insulating layer may be applied to attach the reinforcing mesh tube and using a wire. Also on sale are all sorts of devices, clips and straps that facilitate this process.
Important: if you use the method of fastening the wire, it is necessary to have a small gap. If the pipe pull tightly, then after a while it can succumb to the strain.
Recommended value laid contour length -. 50-60 m If at this distance it is impossible to invest, you need to create a new path.
Note: in this situation need to purchase double-header.
To compensate for heat losses are different ways of laying pipes.
This pipe-laying in the form of a snake. The highest temperature is at the beginning of the pipe, for such a reason it is best to start the laying side walls and windows facing outside the house. This method is suitable for areas with medium and small area.
Its essence is as follows: supply and return pipes arranged in parallel, the cooling pipes is compensated by neighboring heating. This styling is often used in areas with high heat consumption and in areas with a large area.
Important: you need to buy only high-quality pipe, because the floor is installed for many years.
If in the future there are thoughts on the use of non-freezing liquid, it is better to install plastic pipes, they are more resistant to aggressive environments.
The fourth stage - screed
After installation it is necessary to conduct test operation, if all is well, then you can safely fill in the floor (minimum height of 3 cm, maximum - 7 cm).
As for the sand-cement screed, you can buy a special mixture for underfloor heating, there is a choice, would be money.
The fifth stage - topcoat
At this point, the best option - installationtiles, since it has a large thermal conductivity. If the use of the laminate, it is only those models that are combined with underfloor heating.
If there are used natural materials, such as parquet flooring, it is best to seek professional help, there are important pokolku accurate calculations.
Properly laid a warm water floor will delight the residents of the house more than a year and give warmth and comfort and a touch of bare feet on the floor to be enjoyable.
