Autonomous heating system today is for anyone is not something special. Due to the appearance on the market of a new modern heating equipment, various auxiliary equipment and supplies, it was possible to create an effective heating system in residential buildings of any design.
Of particular interest among consumers is the possibility to equip the water heating system in the houses of wooden structure. Villas, baths, country houses and cottages are now becoming the main objects, which due to the heating equipment can significantly increase the level of comfort. The ability to use underfloor heating as the most effective way of heating in homes and apartment buildings, in this respect, becomes today a key issue. Not always building or premises is responsible for the installation of technological parameters of water heating floor, but practical experience and skills allow us to find good engineering solution to this question. Plank without covering, radiant floor heating is a case in point.
Grazing system warm water floors. The features and advantages of the method
Warm water floors already managed to prove in practice its effectiveness and efficiency. I use this method of heating can be created inside the premises the necessary comfort. It's about suburban homes for baths and saunas. However, most of these buildings have a wooden structure, including the overlap. Hence, there are difficulties with the practical use of water as floors heating system.
Traditionally, capital stone structure, where the concrete slab is used, laying of the heating water circuit for heating floors made concrete screed. In houses with wooden beams, such technology is not acceptable. The small height of the rooms, the design features of the building does not allow to equip a warm floor in the conventional design.
It's important to know! For the inhabitants of a city apartment, you should know for a holiday, a wooden house. Weight concrete screed with a water circuit is 200-300 kg / m2. Therefore the whole construction of the heating surface of the concrete mass can reach decent. For a room of 15 square meters. meters this tie will have a weight of 5-6 tons.
Do withstand such weight without visible damage, floors in the flats high-rise buildings and structures in wooden buildings? Question!
If the question is closed concrete screed, which is an alternative in this case for those who want to do at the house underfloor heating. Grazing system in a wooden house for water floor heating is quite logical and best solution of the problem. In addition, this method has some advantages. For instance:
- grazing system has a low weight, which allows working with any beams;
- low altitude layer cake saves useful height of the heated space;
- fast installation, allows you to immediately start laying the finishing coat;
- minimum technical requirements to the ground.
Types grazing system warm water floors
The inhabitants of apartment buildings constructed of wood, we can recommend the installation of water floor by flat by two species:
- water floor laid on a wooden base;
- heating floors, installation is carried out on a polystyrene liner.
Each form has its differences and peculiarities. In fact, both versions have a similar structure. Water heating circuits are mounted on a wooden or polystyrene matrix in which there are special grooves for laying the pipeline. An important place in the flatness of the construction occupy the metal plates that distribute the heat throughout the floor in a heated room.
On a note: in the concrete screed, heat is transferred from the pipeline with a circulating coolant therein directly concrete surface. Concrete has a high thermal conductivity and heat distribution is uniform.
Lining for heating pipes can be made of different materials. With regard to the topcoat, there is almost the same options as in the case of concrete floors with water. For a residential house and changing room in the bath it is recommended to use laminate or linoleum. In the shower room in the bathroom or in the bathroom grazing system can be advantageously equipped with ceramic tiles.
Wooden plank floor heating. Application Method
Typically, wood is used as the base material in those homes and places where the majority (if not the whole structure) is made of wooden parts and elements. The system can be assembled from modules and have rack and pinions basis. In the first case the finished modules made of wood with already existing grooves for laying the water loop. With plank system slatted mounted via rails and boards. In detail, the features of both ways of laying grazing system are various ways of laying water pipes.
Modular assembly unlike polystyrene embodiment is based on the integrated use of special plates (modules) of chipboard. For this method, the main feature consists in warming procedure overlaps. Between joists space is filled with expanded polystyrene or mineral wool insulating materials, heat barring care down.
Rack system is different from modular assembly that is used in the process of installation is not finished whole units, and individual slats and boards. With these items based on a lattice is created, which has already carried out the water circuit assembly. All the empty space in the cell of the lattice is filled with insulation. In the intervals between heating circuit loops necessarily stacked metal plates.
Specificity of the wooden-plank floor of all modifications is as follows:
- Modules for wooden packing must be mounted directly on the joists, keeping in step 600 mm. The space between the joists is filled with insulation. The distance between the individual modules is 20 mm, which would eliminate the effects of thermal expansion. Among themselves ready modules are held together with special locks;
On a note: recommended procedure Scandinavian wooden stacking modules. To achieve the integrity and rigidity of the wooden structure, wooden modules are fastened together by metal staples.
- When installing a floor rack water way, it is necessary to pay attention to the preparation of the rough surface. Wooden slats are mounted at a distance that is optimal for a particular loop stacking water circuit;
- Stacking pipes of the water circuit in accordance with project specifications;
- Prepared and assembled from modules construction coated metal plates are stacked in the grooves of the pipe;
- Thin floor coverings which have a solid structure and a thickness of not less than 10 mm, are stacked on the metal plate, the plate previously covered with a thin and soft sound insulation;
- Prior to installation of ceramic tile or laminate stacking, a dial design is specially prepared. Plates of plasterboard, chipboard or Fener stacked on the metal plate are fixed together to give the required stiffness. Later laying of the final coating is made in a conventional manner.
Polystyrene basis for laying of warm water floor
Unlike wood, inlaid design polystyrene system for installing the water warm floor is a bit easier. Polystyrene or the usual, familiar to us all foam has excellent thermal insulation and sound insulation properties. Material for a long time retains its shape without losing their basic technical characteristics.
Application Method of heating floors using polystyrene based on the following:
First step: Plates Styrofoam must take no more than 30 mm thick. In those cases when it is necessary to use foam sheets of greater thickness, is laid on the rough surface of another layer of foam.
Second step: before laying polystyrene, rough surface is leveled to the ideal smooth state. Eliminates differences in elevation, the flaws in the design and construction debris.
Third step: In a polystyrene plate mounted with special grooves of various shapes, rotary and straight, in accordance with the selected scheme of laying a heating circuit. The trading network sold plate fixed pitch 150 and 300 mm. Between a plate fastened special locks - retainers.
Fourth stage: the option of using ready-made plates with existing bosses can rely on more complex circuit pipe laying.
Fifth stage: in again available slots, placed metal plates, and in them it is necessary to lay pipes of the water circuit.
Then everything goes the usual way. Above the substrate plates must be laid and already attempting to install the topcoat. Here, as in the case can be used laminate, linoleum, parquet board with a wooden plank system.
On a note: Equipment for ceramic tile floor is dry screed. Sheets of water-resistant gypsum board, chipboard or plywood perfectly cope with their tasks, in this case.
Consumables to grazing systems underfloor
installation technology and grazing systems, process equipment itself for underfloor heating is not particularly difficult. Similarly selected and consumables. Auxiliary equipment, pumping and mixing a complex manifold, a flow meter, the same as in the conventional technology underfloor laying in a concrete floor. Particular attention deserve at this stage of the pipe from which the loops are water circuits.
On a note: for grazing systems can use any pipe designed specifically for use in heating "warm water floor" systems. These may be metal, copper pipes, metal or plastic. The latter option is preferable as it does not affect the overall weight of the assembly.
Polyethylene pipes are resistant to corrosion, perfectly hold the required operating pressure and resistant to high temperatures. However, be aware that plastic consumables are designed for contact with the coolant temperature does not exceed 270FROM. Otherwise polystyrene substrate may undergo changes due to exposure to high temperature.
For holiday houses polyethylene pipes ideal, since fine interact with antifreeze, pour the heating system.
Polystyrene plates provide a convenient layout of the pipes. Special slots at the top of the plates lead to the laying of the pipeline with a necessary step. Typically, the dimensions of such slabs - 500h1000 mm.
Wooden modules - is usually OSB or particle board, which are made channels for the water circuit. Modules look like ordinary wooden plate dimensions defined selected pipeline laying step. width modules 13,18 and 28 cm are available today.
The most important element grazing systems - heat-spreading metal plates. Usually they are made of galvanized steel or aluminum. The plates have grooves and ribs. The flat portion of the plate must fit snugly in the substrate and in the same manner to the topcoat, thereby transferring heat from the coolant floor covering.
conclusion
Despite the fact that it is difficult to install grazing nothing complicated system is not present, it is, loses all warm concrete floor. However, in some cases, such systems are very convenient. Stacking is not associated with heavy concrete work, it is easy to troubleshoot delivery breakdowns and leaks in the water circuit. In addition, such a warm floor can be quickly dismantled if desired, changing the housing or reconstructed premises.
