How to make a warm floor on a wooden base: installation tips. Electric underfloor heating in a wooden house Lightweight water heated floor in a wooden house

27.06.2020

The desire to make the house warm, cozy and comfortable encourages people to use modern technologies in the field of heating. The installation of warm floors has become especially popular. It is not difficult to install such a system, however, installation, for example, on a wooden base has a number of features.

Purpose of underfloor heating and laying features

A wooden floor resembles a multi-layer cake, the main components of which are rough laying, layers of thermal insulation and waterproofing, a finishing base and a final floor covering. Between these layers, you can lay a warm floor - a modern heating system that allows you to organize space heating.

When installing underfloor heating on a wooden base, the following must be considered:

If wooden floors are part of wooden house, then when installing the system, it is important to remember that during the first year after construction, the walls give a significant shrinkage, which can reach 5%.
Wood is a natural material that is sensitive to changes in the microclimate in the room. With strong changes in humidity and temperature, it can dry out, crack or rot.

First of all, you need to decide whether the warm floor will be the main type of heating, or whether it is planned to install it as an additional one. This affects the choice of equipment power. For example, when installed as the main type of heating, the specific power of the system should be 180 W / sq.m, as an auxiliary - 140 W / sq.m.

For laying on insulated terraces or in winter garden suitable equipment, the power of which is higher by 15-20%. It is necessary to focus on the same indicator when choosing a system if there is a cold basement under the insulated surface.

Laying a warm floor occurs with a predetermined step. Its value depends on the planned intensity of heating. In cool places, such as near outer wall buildings, heating sections can be laid with smaller steps than in the center of the room.

Kinds

One of the varieties of electric underfloor heating - mats

Underfloor heating models are divided into two groups:

Electric floors are specialized current-carrying systems consisting of heating mats, cables or a special heating film.
Water floors - structures made of tubes with a coolant circulating inside, which are attached to the base and connected to centralized heating or their own boiler with a pump.

Electric floors, in turn, are divided into three types:

Thermal cable. It is sold in coils, the models differ in the degree of heating and the amount of heat generated. Power range - 120–180 W/sq.m.
Mats. This is an analogue of a cable floor, in which the heating element is attached to the base with a given pitch.
Infrared film, along the edges of which there are contacts. Power - 150–220 Vm / sq. m.

floors electric type easier in terms of installation and smaller in size, when laying them, it is not always necessary to dismantle the old floor covering. They heat up faster, and with the help of a customizable control system in each room, you can set one or another temperature. Besides, electrical structures durable and can last up to 50 years.

But when installing on a wooden base, it must be remembered that there is a risk of fire in the event of a short circuit. Another disadvantage of electric floors is the high power consumption. When laying such structures, it is also necessary to check whether the electrical wiring can withstand the additional load.

Water systems are safer. All elements of such floors are hidden by the top flooring, so that the pipes do not take up extra space inside the room and do not spoil the interior. When installed on a wooden floor, water systems heat the room evenly, but weaker than electric structures, because the thermal conductivity of wood is low. It should also be borne in mind that there is a risk of leaks, especially at the joints.

In general, water-type underfloor heating is the most common backup heating system.

The choice of heating method also depends on the top coat will be used in the house. If you plan to lay ceramic or porcelain stoneware slabs, it is better to choose mats or a standard heat cable for heating. For a parquet board or a laminate, a film heating system is used. Water heated floor can be used with all types of floor coverings.

At correct installation and compliance with basic safety and operating rules, all types of structures are suitable for installation on a wooden floor.

Water heated floors are neater and safer than electric ones.

Installation of water heated floors on a wooden base

Building level.
Set of wrenches and wrenches.
A set of screwdrivers or a screwdriver.
Scissors for pipes from metalplastic.
Hot welding.
Roulette.
Pipes for the circulation of the coolant.
Waterproofing film
Thermal insulation material
Fasteners - clamps, brackets, straps and so on.
Equipment for connection to heating system: couplings, adapters, mixers, collectors.

To create a warm floor, pipes of various types can be used: metal, metal-plastic, plastic, suture, seamless and others. The most popular variety is metal-plastic lines of a seamless type.

Water system device

When laying a pipe system on an existing wooden floor, it is necessary to assess its condition. If there are small gaps, they must be sealed with heat-insulating material or grout mixtures. In the case when the old floor cannot be repaired, it must be dismantled. The grounds for dismantling are:

Lack of insulation. The wind can “walk” under the boards.
Too much distance between the individual lags. It should not exceed 50-60 centimeters.

After checking and possibly dismantling the old wooden floor, you can proceed with the installation new design. It is produced in several stages:

Do-it-yourself installation of a cable heating system

Necessary materials and tools

In the process of installing the cable floor, you will need a set of equipment and tools:

Heating cable.
Temperature controller.
Foil and material for thermal insulation.
Corrugated tube.
Mounting tape.
Measuring instruments (ohmmeter, voltmeter) necessary to test the network.
Mounting elements.
Working tools: pliers, screwdrivers, scissors, tape measure.

Installation guide

When installing cable construction it is necessary to take into account a number of nuances:

The presence of a thermostat in the system minimizes the risk of fire and overheating of floor coverings. In wooden buildings, the maximum temperature level is 40 degrees.
The heating elements are evenly distributed over the area of the room. The exception is areas where cabinets, sofas and other heavy objects are placed. With constant exposure, their weight can deform the cable.
The height of the covering laid on top of the electric heating system depends on the type of wood. If the surface is hardwood (oak or beech), then the height limit is 2.4 mm. For "soft" varieties, this figure is 2.2 cm.

indoors with warm floors it is undesirable to place carpets. They prevent heat from spreading around the room.

The main thing when laying the cable is to evenly distribute it over the entire surface of the floor.

Technology installation work comes down to this:

Ceilings are cleaned of dust and other contaminants.
Cracks are closed with grout mixtures produced for the treatment of wood surfaces. enjoy mounting foam not recommended: the product has high insulating properties.
The bars of the rough base are laid. Fastening to the base is done with self-tapping screws.
A thermal insulation layer is placed in the interlayer between the bars. The most commonly used foil acts as an insulator and reflector of heat rays emitted by heating devices.
A galvanized mesh is laid over the thermal insulation layer.
A heating cable is laid on the grid.
At the intersection of the cable with the bars, small cuts are made.
The fastening of wires with bars is carried out using a mounting film. If you need to secure the cable to the grid, you can use clamps.

Installation of film heating on wooden floors

When preparing the base for the installation of the film system, it is not necessary to dismantle the old coating. It is necessary only in case of significant physical wear.

Necessary materials and tools

When installing an infrared underfloor heating, you will need the following tools and materials:

Heating film.
Polyethylene film.
Heat insulating underlay.
thermostat and temperature sensor.
Wire (section - from 2.5 sq. mm).
Tools: scissors, knife (can be stationery), indicator screwdriver, tape measure, pliers.

Mounting technology

If you plan to use infrared film as the main source of heating, you need to ensure that it covers more than 70% of the floor.

Sheets of infrared film should be placed evenly on the floor, but in no case should they overlap

Self-assembly and the infrared floor is connected according to the following algorithm:

Cleaning the floor from dust and other contaminants. Work takes place on a dry, cleaned surface.
With a wet draft layer, the thermal film is waterproofed. For this, it is used polyethylene film up to 50 microns thick.
A film made of polypropylene or metallized lavsan is used as a heat reflector (aluminum foil cannot be used for these purposes). First you need to cut the material. If a warm floor is mounted in a large room, you need to ensure that the length of the film is no more than 10 meters.
The material is laid at a distance of 25–30 cm from each wall. The thermal film is laid out on the floor with copper tires down. It is forbidden to step on the film, drop tools. It is also not allowed to overlap two sheets on top of each other. Before laying, you should mark out the room, determine where heavy furniture and equipment will stand, and avoid these places. Otherwise, due to constant pressure, the thermal film will deteriorate.

To connect the system to the electrical network, it is better to invite a competent electrician. If there is a desire to do it yourself, then the work should be organized as follows:

Strip the wire (8–10 mm) and insert the end into the terminal.
The contact is established on a sheet of film. Connection points and cut lines are insulated with vinyl mastic tape.
After connecting all the sheets, the resistance is measured at the ends of the wires connected to the thermostat.
Next, the load is calculated. For this, the formula W=V2/R is used, where V is the voltage in the network, R is the resistance. The final figure should be about 20-25% lower than the one indicated on the thermostat. After that, you can connect the device.
Thermal film strips are connected to the thermostat in parallel. To avoid possible damage to the wiring, individual sections are hidden under thermal insulation.
Then the temperature sensor is placed. The device is included with the thermostat. The installation location depends on what material is planned to be used as a finishing coating: if it is soft, then the sensor is installed in a place with a minimum load.
Connecting the thermostat to the network and testing the system for contact overheating, sparking, and so on.

After completion of all work on the installation of the film floor, the finish coating is laid. If it is planned to use ceramic or porcelain stoneware tiles, a mounting grid is preliminarily laid out on the floor and fixed in places where there is no thermal film. After installation adhesive solution, with which the tile is mounted, must dry. This will take about a month. It is not recommended to turn on the warm floor until this moment.

The ideal microclimate in the room is achieved with the help of heating devices. To obtain the optimal temperature in the room, you need to follow the rules for choosing and installing a warm floor on a wooden base, which allow any homeowner to easily install the selected system.

Underfloor heating is a very popular type of heating today, used both independently and along with other systems. When it appeared, it was used mainly on the first floors of buildings, using a concrete screed.

Such a screed has a rather large weight (about 300 kg per m2) and cannot be used in most wooden houses, especially on the second and third floors, since the structural floors simply cannot withstand such a load.

The Finns were the first to install warm floors without a wet screed, who came up with a special technology using hypno-fiber sheets. Over time, more and more new laying methods have appeared that allow the use of this type of heating system in any buildings, regardless of their strength and number of storeys. They make it easy to lay pipes with coolant not only in full-fledged residential buildings, but even in such light buildings as a wooden sauna or bath.

Today we will look at several ways step by step installation underfloor heating wooden lags, although there are many more of them in the sowing case, and some changes can be made to each depending on design features premises.

Warm water floor for wooden floors step by step

So, we step by step make a water floor on a wooden one. If the latter needs to be done from scratch, then work will start from the following points:

Logs are the basis of a wooden floor, and its arrangement begins with their installation. They are laid at a distance of 60 cm from each other, which guarantees high quality and durability of the future surface. Fastening is carried out using special galvanized supports, which can be bought at any hardware store.
After the logs are fixed, a subfloor is laid out from ordinary boards, which is necessary for laying waterproofing and insulation. It is necessary to wrap the logs themselves with a waterproofing film. Can be used as a heater mineral plate well, a basalt base, laid in several layers so that its total thickness is 10 cm.
On top of the hydro- and heat-insulating layer, boards of the main floor are laid and mounted on the logs.

If you already have a finished wooden floor, and you only have to arrange a warm floor, you skip the previous paragraphs and deal exclusively with the preparation of the base. It is thoroughly cleaned of debris, if necessary, leveled to an acceptable standard.

AT step by step instructions for a warm water floor on a wooden floor, the next item is the installation of a dry screed, in which the pipes of the warm floor will be located. It can be made from the most different materials: gypsum-fiber sheets, expanded polystyrene, chipboard and others. In our article on how to make a water heated floor on wooden base step by step, we will consider the option with chipboard.

Pre-prepared chipboard boards are laid on the finishing floor. In order to correctly cut out the fragments, the whole board is attached to the logs and a contour is applied to it, along which the pipes will be located. The corners of the strips are made rounded in those places where the system will bend. We lay the finished fragments in the following sequence: first, one row along the walls, and then over the entire area of \u200b\u200bthe room. We leave a gap between the strips, sufficient to lay pipes in it, but at the same time not leaving too much free space.

Chipboard installation

2. We mount heat spreaders - special metal sheets made of galvanized steel or aluminum, and having special profiles for pipes. They are necessary in order for the system to work more efficiently, and heat is distributed evenly over the entire surface of the floor. If you want to save money, you can use ordinary galvanized iron sheets sold at any hardware store. Their thickness should be 0.5 mm. Metal sheets are attached to the laid chipboard with simple nails.

3. Groove metal sheets we lay the pipes of the heating system, which are then connected to the collector.

4. The system is pressure tested (filled with water and kept under pressure) in order to make sure that it is tight and operable.

5. Sheets of plywood are attached to the laid out structure using self-tapping screws. They must be at least 1 cm thick. A 0.5 mm wide gap is left between the plywood, which can be filled with sealant if desired. It is necessary so that the finished floor does not deform if the wood absorbs moisture and expands.

6. In the step-by-step instructions for a water-heated floor on a wooden base, the last step is laying the finishing floor covering. Using the described technology, it can be made from any materials - tiles, laminate, carpet. If a laminate is chosen, then a plywood underlay is not used due to the thermal insulation properties of this material. If you have to lay linoleum, you can not choose cheap options, since when heated they can emit an unpleasant odor.

Tips: 1. For a warm floor, it is better to purchase pipes with a diameter of 1.6 cm, since it is in them that the coolant circulates in the most optimal way.

Do not make the length of the heating circuit more than 100 m, because when traveling longer distances, the coolant will cool down, and in some areas the floor temperature will be significantly lower. If you need a longer contour, it is better to break it into sections.
In order to make the heating system more efficient, experts recommend using foil pipe windings.
Chipboard modules, milled at the factory and ready for use, can be bought at specialized hardware stores. Such kits include all the necessary components - from fasteners to metal heat spreaders and pipes. The cost of such sets significantly exceeds the price of conventional sheets, but at the same time, labor costs and time for creating a dry screed are significantly reduced.
Correctly select the contour along which you will lay the pipes - the “snake” simply fits, but is only suitable for small spaces, since the coolant has time to cool down in it along the way, and cold spots will form in some areas of the floor. AT large rooms it is better to use "spiral".

The second option for arranging a warm floor along the lags

There is another technology that many may like. It is done step by step as follows:

Between the lags, a raised floor is made of wooden boards, OSB and chipboard.
A heater is laid between the beams, for which it is best to use expanded polystyrene with bosses. It not only has excellent thermal conductivity characteristics, but also allows you to quickly and conveniently lay pipes and metal reflectors. The surface of the insulation should practically reach the upper edge of the log, but at the same time the elements of the warm floor should not rest against the substrate.
In the logs, grooves are prepared in those places where the pipes will cross them. The pipes themselves must be wrapped in corrugation in those places where they will pass through the groove, so that as a result of thermal expansion of the materials they do not rub against the wood.
Metal heat reflectors and water pipes are laid.
The system is tested for operability and tightness, after which it is possible to start manufacturing the substrate and finishing.

Underfloor heating with insulation

In order to shorten the workflow, underfloor heating pipes can be placed directly on the insulation layer located on the raised floor. In this case, only polystyrene should be used as a heater, which will make the system work as efficiently as possible. Mineral wool does not have such heat-conducting properties.

At this method pipes will be located below the level of the lag. The space can be filled to the desired level gypsum mixture, or, if you want to completely dispense with wet processes, fill it with ordinary sand. These materials will become a kind of analogue of a concrete screed, albeit less effective, and will conduct heat to the main floor.

The easiest option for laying a warm floor on the logs

There is a very simple option for laying a warm floor along the logs, which does not involve creating a screed at all. It is mounted much faster, but at the same time it has a significant drawback: due to the lack of heat-conducting materials, the floor heats up worse, and a certain part of the heat does not go up, but down. According to this technology, the heat-distributing elements are attached directly to the logs themselves, and the pipes, as it were, sag in their gutters above the raised floor. Metal plates in this case also act as another leveling layer before finishing the floor.

Conclusion. Properly designed and installed underfloor heating can significantly influence the temperature and create a comfortable environment in the house. Installing a warm water floor on a wooden base is not as difficult a task as it might seem initially to a person who does not have much experience in conducting construction works. If you strictly follow the instructions, you will be able to make a high-quality heating system that will last for many years. There are a lot of technologies for installing systems on logs, so everyone chooses the most suitable one for themselves, depending on the characteristics of the room and their own capabilities.

Every year underfloor heating is becoming more and more popular.

But, unfortunately, the owners of private houses can not make all types of underfloor heating, since wooden floors will not withstand heavy loads.

Types of underfloor heating that can be laid on wooden floors

There are two types warm systems: water and electric. They are equivalent in creating a comfortable environment, evenly warm up the area of the room, there are no drafts on them, but they differ in the installation method and operating cost.

Water heated floor

Water floor - a circuit of pipes with a coolant inside, which is connected to the heating system. More often, such structures are mounted in a concrete screed, but for houses with wooden floors it is not suitable because of the impressive weight, because not every wooden base can withstand it. Therefore, it is recommended to install this type of floors in a “dry” way - without a screed.

Hydro structures are popular for heating wooden houses, as they are safe, unlike electrical types and their operating cost is acceptable. The only negative is the possibility of leakage at the junction of pipes.

Electric floors

Electrical devices are a circuit of wires that serves as a heating element. There are: cable and infrared.

Cable systems, as well as water floors, are more often mounted in a screed, but if available wooden floors recommended laying without screed. The infrared view does not need concrete pouring, and the installation process is the easiest.

The device - electric underfloor heating is less commonly used in log houses, because:

has a higher operating cost;
fire hazard, although correct installation the risk is minimized.

Despite these shortcomings, electric floors can be done in wooden house, as they have the following positive aspects:

simple installation, in comparison with the water system - they have smaller dimensions;
quickly warm up the room;
it is possible to regulate the temperature in each room;
service life of more than 50 years.

There is no consensus on which heated floors are better to do in a wooden house with your own hands, the main thing is that they are light - without a screed.

If we start from the price of heat resources, then it is more profitable water system. At desire to keep height of ceilings - infrared. And if you want to save on the construction of the structure - electric.

Summing up, we can say that in houses with wooden floors it is permissible to install any type of underfloor heating, the main thing is to do it in accordance with the technology and in compliance with safety measures.

Note! It is better to install underfloor heating when building a house or in the process of overhaul.

Installation of a water-heated floor without a screed

The most common method of making water heated floors in a private house with wooden floors is flooring - without a screed. The bottom line is laying pipes between the lags or on draft boards.

Before starting work, you need to prepare a tool and buy material. In addition, you should prepare a circuit laying scheme: "snail" or "snake".

If you decide to do, in it you will find step by step installation how to do the styling yourself.

Foundation preparation

Feature installation of a warm water floor in a house with wooden floors, which was operated long time, consists in assessing the condition of the floors. If the building is new, then these steps are not required.

The assessment consists of examining:

beams - determine the degree of strength;
floor - for cracks;
bases - to detect differences (no more than 3 mm are allowed).

If necessary, you need to replace rotten beams, dry the wood, smooth out irregularities on the surface and seal the cracks with sealant. Then, treat the wooden floor with an antiseptic.

If the foundation has become obsolete, then it must be dismantled and a new one built.

Subfloor installation

On a prepared, even base, a draft floor made of wood of any kind is mounted, the main thing is to prevent the formation of cracks. Boards should have a thickness of 20 mm, they are fixed to the base with self-tapping screws.

Laying waterproofing material

A hydro-vapor barrier film is spread on the floor, ordinary polyethylene will not work, as condensation will form.

The product is laid with the membrane side down, with an overlap of one sheet on the other - 10 cm, and is connected to each other using double-sided adhesive tape.

Lag installation

The installation process should begin with fixing the corners. They are fixed on opposite walls in increments of 60 cm. Logs are installed on the corners and aligned horizontally, parallel to the raised floor.

Installation of thermal insulation

As thermal insulation material can be used mineral wool in slabs or basalt insulation. During the laying process, deformation of the plates should not be allowed, otherwise they will partially lose their heat-shielding properties. The material is laid between the lags, a layer of 10 cm.

Note! The thermal insulation layer must be at least 5 cm below the height of the lag to create a ventilation gap.

Installation of waterproofing

The second layer of waterproofing is mounted. The polyethylene film should be laid on the logs in a stretch, it should not sag, and is fastened with a stapler to wooden beams.

Substrate preparation for pipes

Across the log, slats 2 cm thick are nailed, with an indent from the walls of 30 mm. There should be grooves between them, their size depends on the pipe laying step, the standard one is 20 mm. Metal plates are installed in these grooves, into which water heating elements will be mounted.

Important! Wooden slats it also needs to be treated with a hydrophobic agent.

It is possible to replace the aluminum plates with foil, which should be wrapped around the pipes before they are laid in the grooves. One end of the foil must be fixed with a stapler to the rails.

Circuit setting

The heating circuit pipes are placed in the grooves on the mounted reflective profile. To turn the pipe, it is necessary to shorten the board from the end in this area by 10 - 15 cm.

Note! For installation in houses with wooden floors, pipes with a diameter of 16 mm are recommended. They are strong, easy to bend, mounted without the use of special tools, and a single piece provides reliable tightness.

Connection

There are several ways to connect the water circuit. The simplest is through the taps to the central heating, this is to allow manual control. To connect to a home heating system, a pump must be installed.

Important! It is necessary to check the operation of the device for the degree of heating and leakage before mounting the finish coat.

Laying underlay for finishing coat

Gypsum fiber boards or chipboard sheets can be used as flooring. They should completely cover the heating elements, which are well recessed into the grooves.

Floor covering installation

The final layer of the "pie" is laid. The main thing is that it is combined with warm devices.

On this, the process of installing a water-heated floor on wooden floors without a screed is completed. Despite the laboriousness this method, it is popular, as it is less dirty and dusty, and does not create such a load on the floors.

Note! It is possible to install a water circuit on foam polystyrene foil mats with bosses. In this case, the installation of the system is simplified.

Foil-coated polystyrene boards are laid on the prepared rough base, they serve as hydro and thermal insulation, pipes are mounted and fixed with bosses, plywood and flooring are placed on top.

Do-it-yourself electric floor installation

You can make electric underfloor heating in a wooden house without a concrete screed. Let's consider two ways:

on a solid wooden floor;
on the lags.

The first method is simpler, but practically unsuitable for cable types of floors, as it has an impressive thickness. This method is suitable for infrared film systems.

Installation of electric infrared floors on a solid wood floor

Infrared film is the easiest option to make underfloor heating in a wooden house, since the process will not take much time and the design will not take up usable area, because the thickness of the “pie” is small.

To begin work on arranging infrared underfloor heating in a private house without a screed with your own hands, you should draw up a plan for the placement of the film and the location of the thermostat.

The very process of building a "pie" of a warm floor in a "dry" way looks like this:

A wooden base is being prepared - it should be even, without cracks. To do this, plywood or chipboard is laid on the subfloor, and fixed on self-tapping screws.

A layer of heat material is laid, its thickness must be at least 4 mm. It is laid end-to-end to each other, and fastened with a stapler to the base, and the joints are glued with adhesive tape.

Note! If the room is damp, then waterproofing is laid under the insulation.

The film is being prepared and laid out. The product is cut to the desired length, the film can only be cut along special lines. The cut canvases are laid on the floor according to the scheme, with copper strips down, and fixed with adhesive tape.

Contact clips are installed on copper bars, and wires are connected. Each section is connected separately, so if one section fails, the entire system continues to function. To make the contact strong, it is necessary to squeeze it with pliers.

All unused sections of the film, in the places of its cut, as well as the terminal, should be isolated with bituminous tape.

The temperature sensor is mounted, it is fixed with tape from the bottom of the film, on the black strip. The device itself and the wires from it, going to the thermostat, should be placed in the prepared grooves.
The wires from the sensor and the film are connected to a thermostat mounted on the wall, which is connected to a power source.

Important! Be sure to check the system in operation, and only then lay the finish.

A polyethylene film is laid over the heating elements, it serves as a waterproofing layer.

The final coating is spread on a plywood substrate, which is previously laid on top of the film.

The infrared floor, installed without a screed on wooden floors, is ready for use.

Installation of cable heating on logs

The construction of an electric cable floor on logs is simpler than a water circuit in this way, since deep channels are not required for the cable. You should start by determining the location, scheme and step of laying the cable.

The sequence of work on installing a cable system without a screed:

Base. It must be inspected to identify irregularities and damage that should be repaired.

Logs. They are attached to subfloor for self-tapping screws. In areas where the wire will intersect with the lags, it is required to make grooves for laying the cable.

Thermal insulation. As it is used foil, which is laid between the bars and in the sawn grooves. The foil, in addition to heat-insulating properties, reflects the heat coming from the device.

Galvanized mesh. Apply next layer standard size cells 40 by 40 or 50 by 50. The heating element will be fixed to the grid.
Cable. The wire is laid in accordance with the developed scheme. It is fixed to the grid with the help of clamps, and to the lags - on the mounting film.

Floor connection. A thermostat is mounted on the wall, according to the plan. The temperature sensor is placed in the corrugation, located between the wires, and connected to the thermostat.

Flooring. It serves as a flooring underlay. For these purposes, sheets of plywood are used. There must be a gap of 10 mm between it and the heating elements.
Finish coating. The selected product is laid on top of plywood.

Note! Wood is a good heat insulator, therefore, regardless of the type of underfloor heating, wood flooring should not exceed 21 mm, otherwise the efficiency of the device will decrease.

In addition, it is worth noting that you should not save too much when choosing a material, because low-quality components will quickly fail, and additional investments will be required to dismantle the floor and troubleshoot.

To create a cozy atmosphere in a private house with wooden floors, you can use any type of underfloor heating. The main thing is that when installing a structure without a screed, follow the recommendations of manufacturers of warm systems and safety regulations.

Video instructions

Most people assume that underfloor heating is not necessary for wood flooring. This is mainly due to the advantages natural material like lightness and good insulating properties. In addition, installation is difficult due to the possible deformation of natural wood due to temperature changes and humidity levels. However, today a solution has already been found to the problem of how to combine the boardwalk with modern system floor heating.

Water heated floor without screed is used quite often today. The concrete base, of course, is reliable, but it will not be possible to install it in any room. It is in these cases that an alternative underfloor heating system is used. The installation of such structures is easier than the design of the screed, and in operation they are in no way inferior to it.

Underfloor heating system without screed

If the house is built of timber, the rooms have low ceilings, the implementation of a concrete screed can additionally “capture” an already small space. In addition, laying a concrete base is a laborious and dirty job. In this case, the ideal solution for you will be a warm water floor in a wooden house with your own hands.

A water floor without a concrete base is installed on a wooden or polystyrene coating. Pipes are laid in special recesses. For better distribution of warm air, special metal plates are mounted. The laid pipe system is covered from above with a waterproofing material, and a finishing coating is applied to them.

Piping system for wooden underfloor heating

Advantages of a water heated floor

With a small thickness, such a system allows you to save the usable area of the room. Installation of the structure is easy to carry out on any type of floor. In this case, immediately after installation, you can perform surface finishing.

Some installation features

The mechanism of operation of the underfloor heating system involves the transfer of energy from the coolant to the material above it and the finish coating. Then the floor, heating up, gives off heat to the room.

Water floor heating device

If a regular concrete screed is made on the floor, this principle works great. However, in the case where the laid pipes filled with water or ethylene glycol are not surrounded by concrete base, a natural wood, natural material prevents heat transfer. Of course, water heated floors can be mounted on a wooden floor, but such nuances must be taken into account. Wood still does not let all the energy received from heating into the underground, but indoor heating may not be as efficient.

Despite this, the traditional concrete screed is not the best solution problems as the heavy layer of concrete will put pressure on the plank floor. Even if during construction robust design, natural wood may not be able to withstand heavy loads. In addition, often in a wooden house it is required to equip a bathroom or a bathhouse by installing a warm floor in such rooms, and it is not advisable to make a too strong and massive base in such rooms.

Underfloor heating water floor

Not less than important factor, which complicates the installation of the system, is the presence of a substrate, which must be laid on a wooden floor. At the heart of substrate materials different kinds insulation, which also prevent the free passage of heat. Nevertheless, all the negative aspects of the installation can and should be taken into account and successfully cope with the task. So, if you are interested in how to make a warm water floor on wooden floor, you should be patient and carefully study the special advanced mounting technology.

Other design features

The floor heating system will have light weight. Heating from the pipeline, the structure transfers heat to the coating in full and indirectly to users. During installation, the substrate should be laid under linoleum flooring, carpet or ceramic tiles if the floor is laid in the bathroom.

The arrangement of such a system will not take much time. When installing, there is no need to wait 28 days for the screed to harden.

Laying a water-heated floor on a wooden base

Providing heating

Usually, a water-heated floor on a wooden base is ready for use almost immediately after the installation of the top coat. Another advantage of this design is that it is easy to repair areas of the coating with small defects and damage. It should be noted that the presence cement screed complicates the restoration process.

Laying method

There is a common technology that you need to master if you are interested in the question of how to make a warm floor in a wooden house. The system of a water-heated floor for wooden floors is mounted by the flooring method.

Pipes with a coolant circulating through them are not laid in concrete screed, but on logs or a rough base of boards in specially equipped channels.

Installation of a water floor heating system

In order for heat to be accumulated and distributed properly in the channels, special plates with longitudinal recesses for the heating circuit pipeline are strengthened.

Metal plates not only perform the function of heat transfer, but also make the structure more rigid, which eliminates the need for a substrate.

If you do the installation yourself, you can not buy expensive plates, but use 200 micron foil instead. Sometimes when finishing the floor tiles or laying linoleum, the presence of a substrate is desirable. To do this, you will need to purchase GVL sheets or cement-bonded particle boards with the smallest insulation values.

We lay pipes for the water floor system

This can be done in two ways. Their differences lie in the design of channels for placing pipes. As a rule, installation technologies based on modules or rails are used.

For the first option, you should buy special ready-made modules from chipboard. They are already cut recesses at a certain distance from each other. These intervals depend on the expected heat transfer of the system.

Modular laying of a water-heated floor

The kit of such a modular system, as a rule, includes everything you need: the modules themselves with grooves in them, metal plates, fasteners and pipes. It remains only to assemble the structure in accordance with the scheme attached to the product. However, flooring in a modular way is not cheap. Therefore, many prefer an alternative - the budget rack method.

It does not involve equipping channels in chipboard sheets, but stuffing rails. Planks are cut from board or plywood. The gaps between them should be equal to the thickness of the rail, since in the formed grooves of the pipe, external diameter which is 17 mm, should not only fit freely, but also not collapse from the displacement of wood. The width of the guide bars depends on the distance between the pipes in the manufactured structure. So, with the method of laying pipes with a “snake” in increments of 300 millimeters, a 22 mm plank should have a thickness of 278 mm.

Lathing scheme

Mixed method of installation of wooden underfloor heating

Some masters prefer to use another installation method, which is a cross between a rack and a modular option. In this way, you can make underfloor heating easily, quickly and without spending a significant amount.

Get started by choosing edged board quarters with channel sizes. Having measured at least seven centimeters from the wall, they make a strip or recess with a cutter so that the pipe is led to the next row. The thickness of the board must exceed the sampling parameters, and the width must be equal to the step during installation. The rough base does not need to be laid, and the planks are attached to the logs using self-tapping screws.

Installation of a heated structure on a light rack base

If you are laying the system on an old wooden floor, you need to carefully inspect the floor before starting work. It is better to raise the floorboards, check the condition of the lag, if necessary, restore or replace worn and damaged structural elements. Sometimes it should be nailed to the beams on the floor wooden bars and additional insulation.

The next step is laying the insulation.

The process of laying thermal insulation

For this, polyethylene is suitable, which is laid out with an overlap. A damper tape with a width of 5 centimeters is attached to the wall along the perimeter of the floor covering. For installation of a warm floor with a water circuit, it is convenient to use the “snake” pipe laying method.

On a pre-drawn plan-scheme of the room, we mark out the pipe connection area and the equipment attachment points for adjusting the system, you also need to draw the position of the guides with the necessary clearances. Usually it is 150 - 300 millimeters. It is better to use corrugated pipes with a diameter of 16 millimeters. Rails are made to measure.

The method of laying pipes "snake"

Then we fix the guides to the subfloor with self-tapping screws. The corners of the slats in the pipe bends should be rounded off. A foil with a thickness of at least 50 microns is placed in the prepared grooves. Slightly pressing and smoothly bending around the recess, we fix it. At several points, you can attach the material to the rails with a stapler.

If the pipes in the system are also wrapped with foil, then the heat transfer of the structure can be slightly increased.

We lay the pipes in the formed channels. Metal plates are also used for fastening to the subfloor. After that, they connect to the heating circuit and pressurize the heating system. After checking the normal functioning of the water floor, you can immediately proceed to the finishing of the tiles or lay the substrate, if necessary. Of the materials for the substrate, it is recommended to use DSP boards that do not contain formaldehyde.

On the modern market there is a huge variety of heating and space heating systems, which differ in specifics and recommended areas of application.

One of key points The choice of heating system is the construction technology of a particular structure. Water heated floors in a wooden house are the best choice for a wooden structure in terms of efficiency, profitability and safety of the heating system (this is especially true for cottages and country houses).

Water heated floor from "MSK-Teply Dom"

The most common types of installation of a water-heated floor in a wooden house:

Modular design- this installation method involves assembling the base for pipes from prefabricated structural elements that are equipped with holes for laying the circuit. The laying of mats is carried out on a flat surface. flooring. If the floor is uneven, level the plane using Quality Strand Board rough finish sheets or plywood sheets. After installing the main structure, a water-heated floor is laid out; in a wooden house, such a structure is covered on top of the DSP. Then you can lay the finish layer.
Water floors "concrete"- this type of installation is used if other options are not possible. Installation is carried out on top of a wooden base. Before installation, it is necessary to ensure complete insulation of wood from possible moisture ingress. Laying is done with ready-made mixtures with short drying times.
Milling method of wood coating- special grooves are made in the floor for pulling the heating circuit. These works are performed using a special milling machine. This installation is economical and does not require the purchase of an additional building material. Installation is possible if the floor is even and the base has a sufficiently large thickness.
