» Warm floor water: Design with your own hands
The system warm floor water seems relatively simple and efficient building construction. The basic components of the warm floor of the water - layer of concrete and the tubular coil placed inside it under the water heat carrier. This peculiar "pie" is well isolated by lower direction and side sides. As a result, it turns out the original heating structure for the house - water. Make such your own hands is quite real.
Indeed, there are few of the existing heating systems of residential and industrial buildings Ready to compete with warm water floors. Explain the advantage of warm floors on the water is easy.
Thus, for traditional widespread thermal systems built on the basis of heating radiators, fan coils, convectors, the characteristic technological principle is the effect of convection.
The convection method of heating has a significant minus - an uneven distribution of heat fluxes when air heated by radiators is preferably accumulated in the area of \u200b\u200bthe ceiling area.
The lower part of the residential rooms is in the area of \u200b\u200bweakly heated air. The outdoor part remains cold at all, which is unacceptable for the winter season.
From the point of view of the physiological habit of the body, this approach to heating the premises is difficult to call the perfect.

Unlike electric warm flooring on a liquid coolant requires more complex calculations for integration into the heating system. The service life and the ratio of the useful action of the system directly depend on the correctness of the choice of materials, fittings, installation and operation of the heating operation.
In contrast to a common opinion, the choice of pipes for the heat exchanger device in the floor is not so wide. There are two options in total: stitched polyethylene and copper. The most obvious advantages of special materials are durability, resistance to deformities, a small linear expansion coefficient. But the main advantage is an oxygen barrier, which, ultimately, stops the occurrence of precipitate on the inner surface of the pipes.
The meaning of the use of copper in high thermal conductivity of corrosion pipes and resistance. An obvious disadvantage can be called the complexity of installation and the high risk of failure in the presence of solid particles (sand) in the coolant. Despite the fact that the soldering need only an inexpensive gas lamp and a flux, to bend a snake - a difficult task. This is despite the fact that the turns of the copper tube can be several dozen and one error, driving a break, leads to the marriage of the entire segment or the need for an additional soldering.
Polymeric (polyethylene) tubes have a higher thermal expansion coefficient, in addition to this, they lose strength properties when heated above operational temperatures, however, in warm floors, in principle, the coolant does not heat over 40 OS. Convenience of mounting is an obvious plus. Easily snacks and stacked with a spiral or coil. The pipe is supplied in bays of 200 m, allowing you to lay warm floors without a single connection throughout the extension of the future screed. Most of Branded polyethylene tubes implies the use of a special tool for crimping and welding.
Water heating systems with heating floor do not work according to the gravitational principle and always remain highly dependent. Because of this, there is an overheating: the failures in the circulation system and recirculation can be submitted and 70-80ºС, so the means of saving on the use of polymer tubes should be at least partially spent on the improvement of automation and auxiliary mechanisms.
The flow rate of the coolant in the tubes is strictly regulated by the manufacturer, to impose this task for the overall circulation of the system - it means to increase the risk of failures in operation. Before the collector node, a device forced circulation is installed, then each of the circuits is adjusted to adjust the required speed of the duct. This determines maximum length The loops of each contour and the temperature difference at its start and end.
For water pumping, circulation pumps intended for radiator heating systems are used in the system. The diameter of the nozzles is determined by the required tube bandwidth, which the pump is connected to the collector. The height of the rise (or injected pressure) is determined by the total hydrodynamic resistance of the pipes declared by their manufacturer for different loop configurations and bending radii. Each connection requires an increase in the height of the lifting. Adjusting the speed for pumping floor pumps is not required, however, with accelerated circulation, more intensive pumping system is possible for quickly output.
When using more than one branch for heating the floor, the presence of a collector node (rowing) is strictly necessary. An independent collector solder even for two loops will not give the desired result, balance the lines in the absence of uniform distribution and the valve controls are almost impossible.
The collector is selected both by the number of branches and through the total bandwidth. In essence, this is a multichannel flow regulator. From the case materials, stainless steel and high-quality brass are most preferred. Two types of collectors can be used for warm floor. With a difference in the length of the contours less than 20-30 meters, ordinary brass with ball valves are suitable. With larger scattering of hydrodynamic resistances, a specialized collector is needed with flow regulators on each removal.
Please note that dual (feed + return) collector buy not necessarily. You can install a high-quality mixer with flow meters on the feed line, and the return to the return - cheapest with valve (not ball) cranes. Separately, it is worth paying attention to which type of pipes the collector node is calculated. Most cheap items imply a connection of MP pipes that are good for a warm floor and therefore apply more and less. For contours from polyethylene, it is better to spend money on reliable and proven rehau collectorsFor systems on copper tubes - Valtec and ape. Accession copper tubes The collector is recommended through the collapse and / or threaded fitting, to solder is not recommended for low maintainability of such compounds.
Comb rod itself is not the whole collector. As a collection, the mixing unit is equipped with a special reinforcement, providing the water temperature adjustment before submitting to the system. It can be mixed as hot waterIt is also cold that the root determines the specifics of the operation of two types of mixing.
Simple warm floor switching circuit. 1 - three-way valve; 2 - circulation pump; 3 - ball valve with thermometer; 4 - Collector distribution with flow meters; 5 - collector inverter with adjustment valves; 6 - Warm floor circuit. Adjusting the temperature in the circuit is carried out manually and highly depends on the temperature of the coolant at the inlet.
The first type uses a closed circulation cycle, mixing hot water with a three-way valve as needed. The disadvantage of the system is that in case of failures in the operation of automatics or the use of solid-fuel boilers, a large amount of hot water can permanently, adversely affecting polymers, as well as on floor covering and microclimate in the room. Therefore, the hot water swap is practiced mainly in systems on copper tubes.
Ready mixing knot for warm floor. Adjusting the temperature and the degree of mixing of the coolant is performed completely in automatic mode
For polyethylene contours, more expensive collectors, mixing cold water From the return to reduce the incoming temperature. The complexity of such mixing nodes is due to the presence of an additional recycling pump. Adjustment can be performed as a custom double valve and an electronic thermostat, controlling the rotation of the pump engine. The latter is an example of the struggle for the accuracy and reduction of the inertia of the system, to the word, very successful. However, such systems are energy-dependent.
To take a collector assembly - a controversial question. Of course, the presence of a guarantee is an obvious plus, but it does not always work out to find a model with the necessary strapping and the number of taps, in such cases there will have to collect the device itself.
Piece of water warm floor is: polymeric insulation, heating tubes and heat accumulating screed in order from below up. The thickness and used materials of the main layers should be selected in accordance with the operating parameters of the system.
The insulation is selected taking into account the planned heating temperature, and if more precisely, the temperature difference between the warm and rough floors. Mainly use EPPS or PPU plate with docking edges. This material is practically unpacked with a distributed load, while the heat transfer resistance indicators are among the highest. Estimated thickness polymer insulation - 35 mm for temperature difference in 30 ºС and then 3 mm for every 5 ºС.
Methods of warm flooring in a private house. The three options for fastening and distributing pipes are proposed: a - the use of special mounting mats for a warm floor. In - Installation according to the reinforcing grid in 10 cm with plastic screeds. C - laying of pipes into the prepared gutter in the insulation using reflective screens. Constructive design of a warm floor: 1 - concrete base rough floor; 2 - insulation; 3 - damper tape; four - concrete screed; 5 - floor covering; 6 - reinforcing grid.
In addition to the protection of tubes from damage to the screed adjusts the inertia of the heating system and smoothes the temperature difference between the sections of the floor directly above the tubes and between them. If the boiler works in cyclic mode, the heated concrete will give heat, even if the arrivals of hot water are temporarily not. In case of accidental overheating, the heat screed will provide a temperature drop, excluding pipe damage. The average screed thickness is 1/10-1 / 15 part of the distance between adjacent tubes. By increasing the thickness, you can get rid of the effect of heat zebra with a rare gasket tubing. Naturally, the consumption of materials, as well as the inertia and the system of system output to the mode at the same time.
When the warm floors are used for the soil, it is necessary to squeeze 15-20 cm incompressible layer of PGS. Crushed stone for additional thermal insulation can be replaced with clay. On insulated frame floors Warm floor can be laid at once on top of the waterproofer, which the draft floor is covered in order to avoid exit from the screed of cement milk. At best, under the tubes is arranged a layer of thermal cut-off from PPU or EPPS in 20-25 mm. Even such a thin layer is enough to eliminate the bridges of the cold, presented carrier design Paul, as well as distribute the load from the screed.
Installation of water warm floor should pass on a predetermined scheme. The collector requires a place-equipped space, it can be like a boiler room, and hidden in the wall of the compartment. The rationality of the installation of intermediate manifolds depends on whether the savings are ensured compared with the pipe gasket from the central distribution unit, as well as such an increase in the length of the greatest loop. Supporting the tubes to the heating zones is recommended to be performed by premises that do not require focused heating of the floor: pantry, corridors and others like them.
Mounting the tubes of a warm floor follows only a special mounting system. Perforated tape or grid provide accurate adjustment of the installation step, reliable fixation for the time of frozen the mixture and the clearability necessary for temperature solutions.
Fixing the mounting system to the floor is performed through the insulation without a significant clamp. It is necessary to mount into the holes formed after the flexion of the petals to compress the tubes. Thus, the attachment points are located closest to the heating elements, which eliminates their ascend, offset, or raise the entire system when filling the concrete mixture.

Water Warm Schemes Calculation Pipeline Scheme for Water Warm Gauge Heater For Water Warm Paul Screed Floor Laying Water Warm Paul
Let's talk about the water warm floor, and consider the nuances of manufacture, knowing who the master will be able to independently make it for his home or apartment.
As for "how to do", there are so many information on the Internet that you will easily eat the roof, and there is nothing surprising.
Each plumber - Earth PUP, and does it just as necessary, and the rest do not correctly. Hence so many tips, and one is more wider than the other. It is not worth scolding plumbers for it, such a specific profession has developed.
I am not a plumber in my pure form, but as a wagon, I have repeatedly had to do a water warm floor, and observe how it behaves the process of operation.
Let's start with the schemes.
Three rapid floor schemes are the most common: snake, snake + snake, spiral.
The selection of the scheme depends on the shape and size of the room or the site, which is supposed to heat.
Consider in order.
1. Snake is the most simple in the manufacture. But such a contour is great for working pressure, and as a result, after 10-12 turns, there is a tangible difference between the temperature at the beginning and end of the contour.
Therefore, the snake is better to use in small areas, on three or four turns, such as window sills, entrance and toilet "mats".
2. Snake + Snake - also puts pressure, but the temperature difference at the beginning and end of the contour, it is much smaller.
It turns out that because it has two times the number of reservoirs is two times less than that of the snake, and at the end of the contour, the feed goes into the return to the return path and next to the feed.
Based on this, it is better to apply such a scheme for narrow and long corridors, where to make a spiral is difficult, and the snake will give the temperature difference at the opposite ends.
3. Spiral - does not plant pressure. The pressure on the outlet from the collector, which at the outlet of the helix, the same, even at the length of the circuit of 100 m.
The spiral is suitable for large premises. The distribution of heat in it is uniformly, since she is in parallel.
The contour length is determined by the formula 1 m 2 of the floor area x 4-5 p. Pipes + the distance between the contour and the collector multiplied by 2.
4 or 5 meters of the pipe, put on the square meter depends on the heat resistant of the room. If the room is well held heat, and is located above another heated room, then enough 4 meters.
Based on this, the distance between the mains is 20 or, respectively, 16-17 cm.
To visually imagine the location of the contour at the place, draw the installation plan.
This is done like this: the school notebook is taken into the cell, and on the scale of 1 x 20, the plan is drawn.
Then on the same scale, the heating outline is drawn. Two cells - 20 cm, just a step of highways. Thanks to such a scheme, and in the twist will not be mistaken, and the length of the pipe is calculated with a minimum error.
Error, by the way, should always be a plus.
Regarding which pipe from which pipe is better to make a warm floor, a lot of copies are broken. Fans have enough of each material, and everyone claims that the pipe that he recommends is the best option.
Let's think about the pipes from those materials with which I encountered at work, and which are used in the manufacture of a water warm floor.
1. Smooth stainless steel, or copper (close by results and costs).
Advantages:
a) the inner diameter of the pipe in places of connection does not narrow, which facilitates the movement of the coolant;
b) easily repaired during damage;
c) durable, even when hitting the tube, the pipe of the perforator in a flooded tie, it is, but not to break away at once, unlike plastics, which are a little trick, and already a hole.
d) Environmentally friendly material.
It is also possible to speculate about the heat transfer, impurities, the crystal structure of the metal, and how long the wave of infrared radiation generates copper, but it is already for theorists, and the lovers argue. And you will not find a single opinion anywhere. And to practice it does not apply.
The lack of these materials is high cost. That the material is that work is expensive. Not everyone by pocket.
2. Corrugated stainless steel.
Yes, yes do from such a warm floor. Why, I honestly did not understand. Expensive. For repair, equipment and wizard will be required to find. How corrugations affect the progress of the coolant, it is also not clear.
3. Polypropylene.
Easy to do and easily repair. Does not require continuity as metalplastic. In any place, the coupling is put and there are no problems.
Problems are manifested in another:
a) After the installation requires the crimping, to check the welded connections.
boo polypropylene pipe Thick wall, which reduces heat transfer.
c) Internal influxs, with negligent execution, to see which is impossible.
4. Metal plastic.
The optimal material for water warm floors. He passed the time check, easy to install, is available at a price.
Metal-plastic pipe fully meets the requirements of the water warm floor, with the exception of environmental friendliness.
Mounting nuances:
a) Continuity of the contour, since the fitting of metal plastic is narrowed by the passing diameter of half.
b) in closed areas (screed, the thickness of the wall, the box without access) applies only crimp fittingSince it does not flow after turning off the heat, which you can not say about the threaded.
Selection of the manufacturer:
a) Dear and Reliable: Belgian Henco and Italian Valtec.
b) at an average price and reliable: Russian SANMIX and RVK.
c) cheap and unreliable: Chinese Lemen.
The result of using LEMEN:
The pipe worked for 2 years, and the owner constantly fueled the boiler until the water was finally cut out.
I even thought of the sinful thing that this steep pepper was specially cut down the pipes during the laying, so flattened the crack turned out, but then, with a further dismantling, she cracked himself a couple of times in his hands.
It follows from this that the price metal-plastic pipe, not the position on which it is advisable to save.
5. Firmware polyethylene.
While I did not work with him. The reason for this is not flattering feedback from credible, colleagues in the workshop.
If you prevented this material, because of the low price, touch aside additional Materialsrequired for installation and ask the final cost.
Pipe diameter.
Make an accurate calculation, and then the conclusion, which pipe is better Ø16 or ø20, it is difficult, and no need.
This water in the stage has long been ticking on the forums, and there is no single opinion and a single formula for calculating anywhere.
If you dig up to the end, then it takes a bunch source characteristics. This is the characteristics of the coolant, pipe material, boiler, gas quality.
The practical experience tells me that if you make an accurate calculation, then the noticeable difference does not work, except for the price.
In the pictures below, where I will show the installation process, the pipe Ø20, although I prefer Ø16 but this is already the host of the cottage. No beliefs struck His Iron Logic: the thicker - the better. The issue price was closed there.
And after he asked me between business: "And the pipe Ø25 happens?" I preferred to close this topic so as not to run into the laying of the 25th. It will be from him.
The fact that it makes no sense to reflect heat from the bottom of the contour, no one causes any doubts, but in cases where you need to cut off the receipts of the cold from the outside, the insulation under the warm floor is necessary.
That is, if the floor over a cold basement, or on a concrete base, which lies on the ground, or under it open street.
Consider insulation that are used in such cases.
1. Installation on foam. Then, there is a masonry mesh, pipes and further reinforced screed.
What turns out: thin (5 -6 cm.) Monolithic reinforced plate Permeated with expanding and tousing pipes, lies on loose foam.
What she cracks is obvious. The armature will not give up, but since the load on the screed is dynamic, then the movement is inevitable. And where the movement, there is slow destruction.
2. Installation on Penoplex. Polyurex is a hard material, and will withstand dynamic loads, but this hardness places strict requirements for grounding grounds.
Advantages:
but) Good warmth And sound isolation
Disadvantages:
a) Thickness 30 mm and above
b) requires the ideal evenness of the foundation. The sheet of the inferno, when the base irregularities, even 5 mm, will begin to strain, which means to move. If we pull the sheet with umbrellas, the leaf bend will create an emptiness from below, and the emptiness is a potential crashing crack.
3. Installation on the foam. Penofol - foamed foil polyethylene.
Advantages:
a) Not expensive. Price with a thickness of 5 mm. 45 rubles per m 2
b) Tightly falls on an uneven base.
c) good warmth and sound isolation.
d) reflects infrared radiation.
Disadvantages:
a) screed with a thickness of 60 mm. And above squeezes foamophole, why he loses part of its properties.
4. Laying the contour to clay.
Ceramzite is applied in cases where you need to raise the floor of centimeters by 15-20. From the ceramisit, we make a ceramzite concrete, since the warm floor requires a hard base, and from it is already a flat tie.
Additional insulation is not required.
Often a tie for a warm floor, you have to do in two stages. And that's why:
The thickness of the screed over the pipe, for uniform warming, should be 35 mm., With a tolerance of ± 5 mm. It is possible to withstand this size on an even base.
The laid tube has some waviness, and if this waviness will fall on the waviness of the base to which the pipe is attached, it will not work out to withstand this size.
Therefore, the first thing you need to "shoot" the foundation plane, and if the curvature is 0.5-1 centimeters, then this base requires alignment.
The second point is the screed of 70 mm. In this case, the base should be lifted, that is, to make the first screed to which the pipe is attached, then the second finish tie.
In the pictures below the following source:
Screed thickness - 120 mm., The thickness of the first screed is 65 mm., Pipe - 20 mm. The thickness of the finishing screed is 55 mm.
This was the foundation:
Before starting the fill, it is necessary to close everything in the floors, mounting holes. It can be foam, you can be a glasswater-based insulation.
How to make a smooth screed I described in the article, so I will not repeat here. I'll show only the results.
Various tips on how to properly arrange floating floors, give quite a lot useful informationHowever, to carry out its own calculations in a separate example with their help will not be released. Therefore, the efficiency of the design will depend on the hands of the master.
To get started on the device of water warm floors, you will need:
At millimeter paper, draw the plan of the room, taking the scale of 1 cm \u003d 0.5 m. It is also important here to specify the places of doors and windows as accurately as possible. Apply a project for placing the pipes by which hot water will be supplied, clearly melt the loop location. It is important to take certain points into account.
A designed drawing will serve as a base for selecting the required number of pipes and their length. On the millimeter you need to select the length of the contour and according to the scale to transfer the values \u200b\u200bto the present size. It will take another 2 m at the system to approach. They should also be calculated. Thus, you will have the necessary number to install them in a warm water floor system.
For water "carpets" need a high-quality hose
It is necessary to determine the correct diameter of the hose. It usually ranges from 16 to 20 mm. Sometimes 25 mm pipes are used. It depends on the diameter of the pipe and its permissible angle of bending, and the thickness of the future floor.
Stripping from the screed thickness indicator performed after laying the heating system, you will need a specific volume of the solution that you also need to calculate. The volume of water is determined by the sample method. It is important to get a unpropered mixture. However, the solution should not be very thick, as this may affect the complexity of finishing and surface grinding. Sand and cement is taken in the proportion of 3/1. N. e always it is necessary to make the composition of the screed - you can buy a special dry mixture for a liquid floor device.
In order to heat insulation, the material (aluminum foil) is taken in the amount that is needed for a specific area of \u200b\u200bthe room. To do this, you will need to multiply the width of the room at its length - the value in square meters is coming out. Then should take into account the product formation of the material and carry out the subsequent calculation. Laminated canvas are optimal here. The foil on an aluminum-based basis makes it possible to distribute heat evenly and prevent its loss. Foil is a substrate for the main insulation.
All elements for execution heating system It is worth taking a stock. You will need:
According to the scheme under outdoor coating The room houses the hose. The system comes with hot water or another liquid, which transmits heat to the surface used. Ethylene glycol or antifreeze is also used as a heating component. Before the moment when the floor heats up, the carrier of thermal energy distributes and gives thermal energy Nearby placed material and elements.
Now it is possible to perform three types of floor-type: based on wooden canvases, from concrete composition and polystyrene.
In most cases, concrete coatings are used in the construction of the house, less often wooden blocks, including the heating circuit. Consider the concrete bulk floor.
Such a system is installed on reinforced concrete capital overlap with the future creation of a cement-sand tie. Among the masters, such an option is called "filled" or "wet". The reliability and efficacy of the method in practice is manifested in high flow of heat and excellent strength characteristics.
Warm water floor traditional combines such components:
In the general thickness, this device ranges from 7 to 15 cm. On the entire perimeter of the room, experts are recommended to pave a damper tape, which will prevent heat loss and strengthen the screed in the joints with the walls. On overlaps with uneven surfaces or in rooms with an oblong shape, it makes sense to make a deformation seam, which compensates for the expansion of the screed with increasing and decreasing temperatures. For private houses, it is usually performed along the doorway, right under the threshold.
For the heat insulation device, you can take such materials:
In most cases, the profile material is used with a vapor barrier film, which includes special "bins", made to fix pipes 18, 17 and 16 mm. Plates include side locks that make it easier to operate the connection of the shields. By itself, the material is expensive, but at the same time it is very convenient.
The main component of the entire heating system are pipes. It is from them that the service life and the quality of the functioning of the whole water structure depends.
Laying transmitting heat pipes is carried out in two ways: a serpentine or helix. According to the installation technology, the second method is easier and needs less pump operation. In homes where there is a linear slope, it is better to use the first option, because the air from the hose will be easier.
During the preparation of a mixture based on cement and sand for a device of a screed, plasticizing agents are recommended.. If you do not use them, you will have to lay a layer at least 5 cm in the thickness, and if applied, then this value can be reduced to 3 cm. In order for the design for a long time and reliably, you need to use the reinforcing grid. In the case where the area of \u200b\u200bthe room is more than 40 sq.m, they are advised to take a polypropylene fiber as the reinforcing layer.
If we talk about decorative flooring, then the most effective impact of thermal energy provide ceramics and stone. The top element of the whole "cake" can serve as polymeric and textile materials, the thickness of which does not exceed 10 mm. Parquet is allowedHowever, it is worthwhile to take into account the regulations of humidity, since it is possible to face swelling and drying of the tree.
In all embodiments, it is important to take into account the value of the coating - it should not be higher than 0.15 m² / W.
Before performing work, you need to know that the device of such a system takes the space of about 8 cm from the floor. The phased arrangement of a warm floor consists of the following paragraphs:
It is initially removed from the surface of the draft floor all the dirt, garbage, fatty and oil spots, and then proceed to the arrangement of the first layer. As a rule, the house uses a screed based on a mixture of sand and cement. It is placed in strict accordance with the horizontalism - for lighthouses. A device of bulk floors using modern self-leveling mixtures is allowed. So that the heat is distributed evenly, you need to make the surface perfectly smooth.
Scheme - An example of a water warm floor connection
Selected space for docking components that connect the heating pipes and the heat supply system of the house must be hidden in a special cabinet. It is best to make a niche in order to save space. Exemplary cabinet size: 600x400x120 mm. These are standard manifold cabinets. You can place in them both joints and certain regulatory systems.
Make in the closet the access of the return hose and the feeding pipe of the boiler. Secure lock valves on them. Connect the collector and put the cap to its end. An excellent option will be the installation of a splitter.
At one end, you should screw the air molding, and on the other - the drain crane. Thus, you will be able to disconnect the heated system in one or another room, if necessary, perform an emergency repair.
It is important to check the functionality of the system before executing the device of the screed. Only after checking proper work the entire system can be placed the bulk floor or cement mortarMaking perfect smooth surface on established beacons. After the mixture is rejected, you need to make another system operation check and only to be taken for the floor covering device.

Surprise warm floors No one is not possible. New homes or those that just survived overhaulFor the most part have water system Heating hidden under flooring. Here, the temperature of the energy carrier does not exceed 60 0. Despite the laboriousness of the process and the high cost of all components of the water warm floor do with their own hands, do not be so difficult. How to carry out installation, choose components and why it is better to make such a heating this article.
Heating, the temperature of which is low (electrical or water floors), subject to the compliance with the installation technology, is capable of faithfully to serve not one decade. Electrical system It can be mounted for 1-2 days ("Pie" here make it easier), which you can not say about water.
Plus, towards the electric flooring device is that they can be used in any home, private or multi-storey. At the same time, they can be laid even on an old coating.
But the installation of water floors is a big "cake", a clear scheme, painstaking styling and high screed. The collection of construction takes more than a month. But the result on the use of the heating system should level all disadvantages associated with the complexity and the high-cost installation process. This means that it is more profitable to use water floors. So, the table is represented comparative characteristics Water and electric floor.
At the same time heating large squares Warm water floors are more than justified. The desired temperature in the contours is "recruited" for a long time, but "pie", the installation of which is performed flawlessly, can work on a smaller heating mode than at the beginning.

Deciding to make a warm "pie", you need to decide on some aspects. For example, in the house there will be

With clarification of the characteristics of the object, all calculations should begin. It is necessary to decide "pie" of a warm floor - the main heating or only heating. The scheme can skip the place where the furniture will be standing, which no one plans to move over the ages of decades.
So, for the calculations you will need the following knowledge:
Attention! If the length of the pipes exceeds 100 meters, in the circuit, more turns, it means that hydraulic resistance increases, water is worse circulates in the system and as a result, the temperature in the contour is uneven.
Suppose that we have on the ground floor of a private house in a temperate climatic zone of 5 rooms and 1 corridor (its length of 10 meters) is also a boiler room. It will be logical to install a separate circuit in each room. Then through the corridor to the boiler room you need to carry out pipes for connecting to the collector. Thus, make a separate laying of pipes in the corridors there is no need, but to the length of each contour you need to add the distance from the room to the collector.
In our house, heating is only low temperature (step 20 cm). This means that the length of the pipes can be calculated by such a formula:
- This is the square of the room, we have 15 meters;
- the distance between the vita (0.2 meters);
- Standard coefficient, it is needed to take into account the pipe for bend.
Meter pipe.
This is the furthest room, it means that the water will go from 15 with a small meter from the collector to her. Thus, the length of the first circuit, taking into account the distance to the boiler room, is 98 meters.
So you need to calculate each contour. And as a result, to have an idea of \u200b\u200bhow many meters of pipes in our private house is necessary for warm water floors.
Correctly calculating the number of meters, the pipes can be purchased in bulk

To create the system, it will take not only a pipe, but also
A collector is installed on the wall above the floor next to the boiler, the temperature is set for each contour separately. All this can be mounted primarily, and then directly engage in the installation of a warm floor.

A warm flooring device in a private house must observe the order of laying each layer. Right collected design Provide the normal operation of the entire system, and, it means that there will be a comfortable temperature in a private house. General mounting Water warm sex takes no less than a month (so much time is given to drying the screed in winter, summer time is reduced to 2-3 weeks).

In a private house, you need to prepare the basis for laying all the cake layers. The greater it will be, the better. It is necessary to smear the cracks and, if there is a need to fill the base with a screed. Next, the floor device assumes the presence of a waterproofing layer. It is put on the jack, sizing the connection of the construction tape. Dampfer ribbon need to make a break on the walls.
When expanding concrete, the tape is narrowed, clearly determining its borders, thereby improving the quality of the fill

We start collecting "Pie". In the queue laying insulation. There should be no intervals between sheets. Connection locations must be punctured.
It is much easier to work with insulation that has special grooves for pipes.
But on the usual insulation you need to put a foil substrate. Given that the temperature at the outlet of the system should not exceed 60 0, the use of such a substrate will help to use heat energy as efficiently and direct it exclusively for heating the room.
It is easier to put pipes on the insulation when "pie" gets a reinforced layer. It can be a grid or a special track. The main thing is that it can be easily attached to the pipes.
For large rooms, it is better to choose a wide grid that almost do not have to cut. Using the mesh will simplify the laying of water pipes for a warm floor

At step in 20 centimeters, 1 m 2 accounts for at least 5 pipe meters of the pipe. This edge of installation is quite complicated. Laying pipes occurs by different methods, for example, as follows:
When laying pipes, you need to comply with the following requirement: the return and feed must be connected to the collector. Washing contours, their pouring concrete is made after the final assembly of the entire system.
