Any masterful man can make a water-heated floor with his own hands, the video of which can be seen in our article. To do this, you will need to carefully study the installation procedure and listen to useful tips. Materials and tools for this are available in any building supermarket.
Water heated floor with their own hands, video and installation features
There are some options for floor heating devices:
- Water with pipes placed under the concrete screed.
- Electric heating cable.
- Electric infrared.
The most economical of them is the first option. Its disadvantage is some complexity of installation in comparison with other types. However, if you make some effort, you can do everything qualitatively and accurately. Consider step by step the whole technology.
Consider the installation of a water-heated floor system with your own hands, the video will illustrate the nuances not specified in this article. As a base, we take concrete floor slabs. The wooden floor is completely dismantled, and all the garbage is removed from it. Irregularities, potholes and bumps on the plates are puttied and aligned. Places of passage of engineering networks through the plates are covered with cement mortar.
When the surface is dry, then remove all trash and dust with a vacuum cleaner. Arrange waterproofing film materials. In this case, the edges of the film should be superimposed on the walls to the height of the planned finishing coating.
Since we want to create a system that is able to effectively heat our room from below, it is necessary to arrange it so that thermal energy spreads directionally, that is, upwards. This can be done in one way, blocking the possibility of energy loss in the opposite direction. For these purposes, you can use any insulation. It will not allow the heat to evaporate in the wrong direction.
Often used foam, expanded polystyrene foam, mineral wool insulation. In addition, there is a large selection of mats for a warm water floor, which is produced specifically for this purpose. They have grooves for pipe installation and do not require great skills during installation. By choosing such mats, we greatly facilitate the work of twisting and fixing the pipe.
If we stopped at the budget option and decided to do the usual heaters, then they need to be laid over the entire surface of the floor. It is better to use rigid polystyrene plates. Their installation is much more convenient than soft insulation. Joints between sheets glue sticky film. Another layer of waterproofing should be placed on top of the plates, as this measure will eliminate any penetration of moisture to the floor slabs.
Do not forget that the floor is water, and any breakthrough of the pipe can cause a flood in the neighbors. Further along the entire perimeter of the room onto the walls, along the edge of the insulation, we glue a damper tape, which will take on the energy of the concrete screed that expands when the concrete is drying.
Helpful advice! In the foam plates used for insulation when installing a heated floor, you can cut through the grooves for laying pipes. This should be done carefully. In this case, the foam should be at least 8 cm thick. This will allow well drown pipe. Such a measure will make it possible to make the screed thinner.
Pipes of cross-linked polyethylene or metal-plastic with a diameter of 10 to 20 mm are laid on top of the mats for a warm water floor. They are laid out in a spiral or snake in a special way. The closer the turns of the pipe to each other, the more heat will be generated per square meter of floor. It is recommended that this distance be no more than 30 cm.
Pipes are attached to the insulation with special clips that can be purchased. Otherwise, you can come up with staples made of hard wire, which are stuck into the insulation and pressed the pipe. If you have purchased a special insulation that has grooves for the pipe, then there will be no problems at all.
How to choose polypropylene pipes for heating. Product specifications, interior, reinforcement options, marking, diameter and manufacturers.
Both ends of the pipe laid out in the place where there will be a collector for a warm water floor. This device allows you to distribute the flow of coolant through the pipes with high efficiency. It mixes the already cooled water with hot, which makes the heating of the entire floor surface uniform.
With the help of a collector, a heated floor is connected to the main heating system or a separate entrance to the boiler is made. When the system is assembled, it is necessary to run water into it and create maximum pressure. Such pressure testing will help identify leaks and correct these shortcomings.
Helpful advice! There is no need to lay pipes over the entire floor area. Determine in advance where you will have the furniture. There are no pipes needed. These measures save a lot on materials.
Remember that it is impossible to dock pipes inside the screed! Calculate in advance the required footage of pipes for each heating circuit. For greater efficiency, it is not recommended to make heating circuits too long – for a pipe with a thickness of 16 mm, the maximum loop of the circuit can be 65 m, for a pipe with a thickness of 20 mm – 80 m.
After laying all the existing pipes and conducting the crimping system, you can proceed to the device of the concrete screed. It should not be very fat. After all, an excessive layer of concrete will not allow for efficient heating of the room. We need to achieve maximum efficiency from the entire system, so we make the coupler no thicker than 5 – 7 cm.
The use of self-leveling mixtures allows you to distribute the leveling layer very smoothly and at the same time quite thin. When creating a water-heated floor with their own hands, the video shows that it is this screed that is most popular with citizens.
When constructing a screed, it is necessary to pay special attention to the area where the supply and return pipes will go out. They need to gently lead to the mixing unit for a warm floor with their own hands. This element is designed to adjust the temperature of the coolant in the floor heating system.
The water supplied for heating the house can be heated to 95 ° C. It is unlikely that anyone will maintain such a temperature under his feet. In the mixer, the hot and cold water is mixed. Only after that under the floor is supplied coolant, but already of normal temperature. Most often it is not more than 35 ° C.
From what kind of screed we used, depends on the time of its drying. Conventional concrete screed requires at least 3 weeks to dry. Modern self-leveling compounds for screeds can be used in just a few hours. This is another argument in favor of their use when creating a water-heated floor with their own hands. Video of the installation process is sometimes provided with comments on which tie is better to take to level the floor.
On systems of a heat-insulated floor most often do a covering from a tile (kitchen and bathrooms), a laminate and a parquet, linoleum. Less commonly, thicker coatings are used, such as flooring.
Helpful advice! When laying laminate or linoleum, choose materials that have good thermal conductivity. This information can be obtained at the time of purchase. They are written on the packaging or are available from the seller. Low thermal conductivity will significantly reduce the efficiency of the entire system, since it will not allow heat to reach the floor surface quickly.
Creating a water heated floor with your own hands, the video of which you liked, do not forget about its disadvantages and advantages. Note the advantages:
- independence from electricity, if the heating system in the house is non-volatile;
- security. Provided that the installation is performed in accordance with the time-tested technology;
- availability. You will only have to spend money on the pipe and collector for a warm water floor, which are absolutely necessary. All other components can be replaced with general construction materials.
The disadvantage is that the construction of such a structure requires a special tool and the ability to handle it. A longer period for the manufacture of the system, in contrast to the electrical types, especially when using the classic concrete screed.
Install a heated water floor system for everyone. It is only necessary to do this in due form. Then the effect of its use will definitely be the most effective. System safety is ensured by its quality
