Water sex: how does it work?

Flooring water type - a very practical way of heating the home. The system is a fluid heating circuit is mounted under the floor.

Traditional technology requires that the tubes lie in the concrete screed. To heat fed into the coolant circuit is commonly used boiler. Standard models of warm liquid to 60-90ºS, which is unacceptable for underfloor heating.

If you let the coolant temperature with the in-loop, warmed to 45-60ºS floor. Walk on it will not be possible. SNiPy govern permissible for floor heating temperature. It does not exceed 30 ° C.

To obtain such a value will be enough to heat up the liquid in the loop to 35-45ºS. Therefore, in the water system include sex mixing unit. There are mixed liquid from the hot heat exchanger and the boiler return pipe from cooler.

There is another more simple option. If you do not have to use the mount condensing boiler mixing unit.

Design features such boilers require heating possibility coolant to relatively low temperatures. In some cases, the heated coolant is taken from a centralized system, but it requires a special permit, which is not always possible.

Water floor plank

Radiant flooring plank type represents a relatively light construction of wood or plastic elements, which are arranged inside the heating tube

Thus, entering the heating circuit liquid which can be water or antifreeze solution heats the floor. He, in turn, heats the air. The result is a fast and at the same time very uniform heating of the room.

A significant advantage - the most suitable for human temperature distribution in the room. The upper part of the cool air collects at the bottom - the warmer. That living organisms such microclimate is regarded as comfortable. Thus convective currents that are inevitable when the presence of point sources of heat, is observed.

This eliminates the migration of dust and microorganisms. The advantages include minimal and operating costs. All this makes the water floor popular among users. Comparative analysis of water and electrical floor heating systems given in articleAnd view with which we recommend.

Features grazing system

Traditional water type sex embodiment involves installation of pipes in mortar. Fill it with a solution of concrete with special additives that increase its thermal conductivity.

As a result, the concrete pad becomes a kind of accumulator tank, which makes it possible to use a heating system as efficiently as possible. However, the traditional method of arrangement has drawbacks.

Plank floor heating

A wooden base has low thermal inertia, which prevents the system to function properly. To remedy this drawback mounted heat reflecting plate of a metal having high thermal conductivity

The most obvious - too much weight concrete screed. When fluid density about 2000 kg / sq. m, it provides a significant additional burden on the base and carrying.

For concrete slabs such load quite feasible. For wooden floors - extraordinary. For this reason, the traditional method of placing in such cases is not allowed. Here, a so-called grazing system.

It is performed in a low deck, inside which are arranged tubes. For him everything is most commonly used wood, but recently emerged and are commercially available way floorings made of polystyrene.

Tubes are placed in the grooves where and fixed. It is known that the wood conducts heat very poorly. For this reason, wooden systems can not be an effective source of heat.

To remedy this shortcoming, the metal heat conductive elements are inserted into each slot. They also reinforce the structure. Similar parts have in polystyrene decks with metal inserts, a material which is a poor conductor of heat, too. Thus it collects reliable and durable heating system.

Its advantages over traditional analogue may be considered:

  • Light weight flooring that can withstand even hardwood floors.
  • Relatively easy assembly, especially when it comes to industrial models decking.
  • No need for waiting hardening concrete screed. Finishing work can be carried out immediately after installation is complete.
  • Full maintainability. For repairs to lift the deck fragment is sufficient to provide access to the site with a malfunction.

Another unquestionable advantage grazing system - multi-variant, which makes it possible to implement a variety of its modifications. Most of them - homemade. The main drawback of grazing schemes - cool rapidly. Floor is heated in a short time and as quickly gives off heat.

Plank floor heating

A big plus-plank floor of the water - the possibility of a relatively simple repair. To get to the damaged fragments, enough to remove section of flooring and clean underneath flooring

Actually, the amount of heat is limited, which is in the liquid coolant in the tubes. Therefore, when stopping the boiler room soon cooled. For this reason, grazing systems are used more often as a complement to primary heatingEspecially in cold regions.

Apparatus plank heating system

When laying plank system of a kind obtained multilayered cake, it will look at each layer in detail.

Substrate Requirements under construction

The first layer of the cake - properly prepared substrate. It can be any overlap, tentatively aligned. SNiPy regulate the absence of significant height differences, protuberances or roughness. Wooden floor must be flat, without protruding boards.

Each plate should be well secured and must not sag. The maximum allowable limit of the deviation from the horizontal - 2 mm, distributed in 2 m square in any of the existing areas.

Apparatus insulating layer

To prevent heat leakage must arrangement insulating layer. Material for its implementation is chosen individually, based on operating conditions. It should be moisture-resistant, fire-resistant compatible with other building materials.

It is desirable to further protect the insulation and. Whenever possible, it selected the most subtle but effective material.

Variant pipe fixing

On insulation itself flooring is laid under the pipe. There are a variety of options. This may be polystyrene mats with special lugs at the pipe. Such mats are produced in single and redundant heater.

In the latter case, the insulating layer may be unnecessary. As the sheathing sheets may be used lumber sawn grooves with a pipe. They are also produced by industrial methods. Take place to be improvised and decks of rods, bars, etc.

Pipe for moving the coolant

Next, the prepared mounting slots and fit heat pipe. For the maximum and create a snug fit of the heat shield parts are placed inside special profile of aluminum.

If there is no one can make similar elements from galvanized or wrap every detail of a dense foil. Optimally bed an additional layer mounted on top of the foil tube.

The construction of the base under the finish

Above pipes for floor covering is necessary to lay the foundation. It is selected depending on which final coating will be laid.

If you plan to tile installation, ceramic or PVC as well as linoleum or carpeting on the metal parts of wooden flooring is laid water-resistant drywall. If everything for flooring used polystyrene mats, gypsum fiber board is put in two layers.

plank flooring

Plank structure typically served by a base topcoat. It is selected depending on the material which is preferred as a coating. Under the laminate, e.g., bibulous substrate is placed under the tile - moisture resistant plasterboard or chipboard

Under the laminate wood flooring drywall does not fit. Instead, the aluminum plate is placed absorbs excess moisture foamed polyethylene or paperboard substrate.

Instead, you can use water-resistant gypsum fiber grade chipboard or plywood. Good solution - glass-magnesium sheets, which are also good conductors of heat, which is absolutely not superfluous in the regeneration of the floor heating.

Variants of arrangement of water floor

Flooring under water sex can be made in many different ways, especially like the handyman. Consider a few options such structures.

Option №1. Implementation of a turnkey solution

This is the most simple in execution method. At the hardware store sold kit for flooring production. Maybe two versions of this decision. First - polystyrene mats fitted with fastenings for the pipe.

They can be duplicated layer of insulation. In this case they can be laid directly on the ground. The main advantage of these mats - extremely easy installation. However, they are not strong enough to be mounted directly on the floor mats.

Under the soft cover, as well as, and under the tiles have to put two coats of the FCL. Flooring can be assembled from modules made of chipboard. They are prefabricated recesses deposited under the pipe system with a certain step. The modules are equipped with fasteners, metal teploraspredelyayuschimi plates and pipes.

Warm-plank flooring

Mats made of polystyrene - a perfect solution for the arrangement of the water grazing the floor. This option allows you to build super-slim floor water, eat a minimum height of the room

For connection parts provided for locking the connection between them, which considerably facilitates assembly. Such structures are strong enough and does not require additional strengthening. Their main drawback - the high cost.

Any of the ready-made solutions requires careful preparation of the base. If this is the old floor, it provides a thorough revision. Spoiled and discarded parts of repaired. The board is securely fastened, elevation changes are removed. Then all debris and dust is removed, and the base is primed.

After drying stacked and fastened insulation, if required. The next stage - laying the mats. On the outer side of each of them is applied a suitable adhesive, usually a "liquid nail", and the plate is glued to the base. It is important that the glue is well seized and securely hold the mat in place.

If you plan to laying the flooring of chipboard, it is collected in strict accordance with the instructions issued by the manufacturer. Once the channels for pipes will be ready to begin installation. Laying of floor heating pipes It can be made "snake," "scroll" or any other suitable method.

The elements are connected into a single system and are connected to the heating system. Further verification is carried crimping and water floor works, and then proceed to the installation of flooring.

Variant №2. Flooring on logs

The work begins with the preparation of a wooden base. If this is the old floor, carried out all necessary repairs. Then it is necessary to lay the joists on which will lie a warm water floor beneath a wooden floor. Prepared lags exhibit strictly on level with the distance between the elements of the order of 0.6 m.

This is the best option would be to put the details of the long distance. But in this case it would require thicker boards to form a floor.

Warm water floor

Preparation of the substrate - a very important point. It is desirable to lay a new subfloor construction, but you can use the old one, if it is in good condition. All damaged areas should be repaired

Beams are fixed securely to the base. Further therebetween lags settling base on which is stacked insulation. To this end, the beams tamp boards, plywood, particle board or any other suitable material.

If you want to save, you can substitute the base of nail to lag corners or slats, which will build the insulating coating. But we must understand that in this case it must be tough and not loose. On the prepared substrate is placed insulation. This can be a foam, rockwool high density polystyrene, and others.

After formation of the heat insulating mat start manufacturing of flooring. To do this, take a minimum board thickness of 0.03 m. They begin to fasten to the beams. The first fixed distance of 0.02 m from the wall surface, similar to the gap and operate while fixing all other components.

An important point - the choice of the width and secured to the floor boards. It should match the width of the heat distribution plates of metal which will be subsequently inserted into the resulting grooves.

The pipe will be laid, "snake", which implies the need to implement the slots at its corners. For this special leave gaps a width of about 0.15 m through an equal distance from each other.

Water-plank flooring

For formation of the bend pipe which circulates the coolant, a part of boards is fixed at a certain distance from the wall

In practice this is as follows Two boards are screwed to the wall in a departure from 0.5 cm, the following two - at a distance of 5 - 7 cm. And so on until the end of the row.

On the opposite side of the base board those that were fixed to the wall, screwed at a distance, and those with a gap - close. Thus the groove is formed under the pipe bend. After the whole flooring is laid, to begin assembling heat distribution plates.

They are inserted into the grooves formed boards and securely fasten straps or ordinary nails. Optimally, the side lying near meshed plates.

Then there will be formed a continuous transfers heat shield. Now you can start laying the pipes. Make it easier for two. One employee will unwind the bay, and the second will itself laying.

Detail with little effort as it is pressed into the groove of the heat distribution plate. Return pipe contour loop is best spent along the wall under the plank boards.

After the whole circuit to be laid, once again check the installation is correct and it is connected to the heating system. Be sure to perform pressure testing of the water floor. Then you can begin to prepare for the installation of flooring.

Option №3. The design of the guide

Begin with the preparation of the base. As in previous embodiments, it should be lined and strengthened. Then, based on fit any suitable insulation.

The simplest method of laying a floor water is a "snake", so it is used more often. For the design of the guide is to be the best option. To determine the dimensions of parts drawn a precise plan of the room.

Radiant Floor Heating

There are several options for placing a warm water floor. The easiest of all options - snake, the figure is represented by its scheme

It marked sections where it is determined serving water equipment and floor space summing pipes. Then, with strict observance of the selected step of laying rails are drawn. Count the number of parts required, and are defined by their size.

Now you need to prepare a guide. Their cut from any suitable and available material. Then it is possible to start assembly. Items must be stacked on the base in strict accordance with the plan.

Each guide is placed on the rough substrate and securely fastened to it with screws. Between the parts must remain channels required for the installation of pipes. On the highway turning sharp corners sites rails must be rounded, not to accidentally damage the pipe.

After all racks are secured to the base, start packing foil. To do this, take a material thickness of not less than 50 microns. The sheets are pressed into the channels, carefully skirting the each recess. Literally "laying" foil each channel.

The sheets did not move, they are fixed to the rails by means of a stapler. For a better heat transfer is desirable to wrap the pipe before installation of the same foil, but this is not required.

Installation of water-plank floor

To perform a smooth rotation of the pipe and accidentally damage it directing on sites necessarily rounded the bend. Their sharp edges removed

Then inside the pipe is laid prepared channels. To lock it in place in some areas it is attached to the rail or to the floor with metal plates. Upon completion of laying a water floor heating system is connected to and carried mandatory pressurization. If she did not reveal violations of tightness, start preparing for the installation finish.

It is only three mounting options floor heating grazing type. In practice, they are much more. Domestic craftsmen adapted them to their own conditions, selecting the available materials and appropriate technologies.
