The circuit arrangement of warm water floor
Preparation of the base under floor heating
Consider laying water floor heating system with their own hands, the video will illustrate the nuances that are not stipulated in this article. As the base take concrete floor slabs. The wooden floor is completely dismantled and removed all the debris from it. Bumps, potholes and bumps on the plates zashpaklevyvayutsya and aligned. Designated passage of utilities through a plate obscure cement mortar.
When the surface is dry, then vacuumed removed all debris and dust. Arrange the waterproofing of film materials. In this case, the film edges must be superimposed on the wall to the height of the planned finish.

Thermal insulation of the floor base
Since we want to create a system that is able to efficiently heat our room from the bottom, it is necessary to arrange it so that the thermal energy is spread direction, ie upwards. This can be done in one way foreclosing the possibility of leaving energy in the opposite direction. For these purposes, you can use any insulation. He will not allow heat to escape in the wrong direction.
Often used foam, expanded polystyrene foam, mineral wool insulation. In addition, there is a large selection of mats for warm water floor that produce specifically for this purpose. They have grooves for laying pipe and does not require great skill when laying. By selecting such mats, we greatly simplify your work by twisting and fixing the pipe.
The temperature distribution of air indoors under heating radiator heating and floor heating
When we stopped for a budget option and decided to do the usual heaters, they should be laid over the whole floor surface. It is better to use rigid polystyrene plates. Their installation is much easier than soft insulation. The joints between the sheets glued with adhesive tape. Over the plates should put another layer of waterproofing, as this measure will prevent any ingress of moisture to the plates overlap.
Do not forget that the floor in our water, and any breach of the pipe can cause flood the neighbors. Further, around the perimeter of the room on the walls of shear edge insulation damper sizing tape that will take on the energy of the expanding when drying concrete screed.
To mount the warm water in the finished interior floor can use a dry method (clean) screeds
Useful advice!The foam slabs used for insulation when installing floor heating can be cut grooves for laying pipes. It should be done carefully. Thus the foam should not be less than 8 cm. thick. This will allow a well to drown the pipe. Such a measure will make it possible to make thinner screed.
pipe laying
Above mats for warm water floor laid pipes of crosslinked polyethylene or of metal with a diameter of 10 to 20 mm. Their spread spiral or snake in a special way. The closer the windings are pipes to each other, the more thermal energy will come from a square meter of floor. It is recommended that the distance was not more 30 cm.

Are attached to tube a heater special clamps, which can be purchased. Otherwise you can think of stiff wire staples, which are stuck into the insulation and pipe are pressed by them. If you purchased a special insulation, which has grooves for the pipe, the problems do not have any.

Both ends of the laid pipe outputted at the point where there will be a collector for warm water floor. This device allows to distribute the coolant flow through the pipes with high efficiency. It has already cooled is mixed with hot water, which makes heating uniform across the floor surface.
Using Heated floor collector connected to the main heating system or do a separate entrance to the boiler. When the system is assembled, it is necessary to run the water and create the maximum pressure. Such pressure testing will help to identify leaking places and to correct these deficiencies.

Useful advice!There is no need to lay pipes across the floor area. Determine in advance the places where you will be furnished. There tubes are not needed. These measures make it possible to greatly save on materials.
Remember that join pipes inside the screed can not be! Pre-calculate the required yardage pipe for each heating circuit. For greater efficiency is not recommended heating circuits are too long - so that the pipe thickness of 16 mm maximum loop coil may be 65 m, for a tube of 20 mm thickness - 80 m.

screed
After placing all the existing pipes and pressure testing of the system, you can begin installation of concrete ties. It should not be very thick. After the excess layer of concrete will not allow to produce efficient heating of the room. We need to maximize the efficiency of the whole system, so do not tie thicker than 5 - 7 cm.
The use of self-leveling compounds allows to distribute the planarization layer is very smooth and thus sufficiently thin. When you create a water heat-insulated floor with their hands, the video shows that such a strainer It is most popular among citizens.
Comparison of different ways of laying pipes for floor heating
When the device screed It must be particularly attentive to the area which will come out of the pipe flow and return. They need to be careful to draw to a mixer assembly for floor heating with his hands. This element is designed to adjust the coolant temperature in the floor heating system.
Filed for house heating water can be heated to 95 ° C. It is unlikely that anyone will withstand this temperature at his feet. The mixer is a mixing hot water with cold. Only then coolant is supplied under the floor, but the normal temperature. Most often it is not more than 35 ° C.
Scheme thermostat setting for water heating system
From what kind of ties we used it depends on the time it dries. Plain concrete screed needs to dry at least 3 weeks. Modern self-leveling screed compounds can be used within a few hours. This is another argument in favor of their use in creating a water heat-insulated floor with their hands. Video installation process is sometimes provided with a commentary as to what is better to take a screed for floor leveling.

finishing work
On the floor heating system often make a coating of tiles (kitchen and bathrooms), parquet and laminate, linoleum. Less commonly used thicker coatings, such as a floorboard.
Useful advice!When laying laminate or linoleum, select such materials that have good thermal conductivity. This information can be obtained at the time of acquisition. They are written on the package or available from the seller. Low thermal conductivity significantly reduce the efficiency of the system, because they do not allow heat to reach the floor quickly.

Advantages and disadvantages of the type of water underfloor
Creating a water heat-insulated floor with their hands, a video you like, do not forget about his shortcomings and virtues. Note pluses:
- independence from power, if the heating system in the house is nonvolatile;
- efficiency;
- security. Provided that the assembly formed in accordance with the proven technology;
- availability. Only have to spend money on the pipe and reservoir for warm water floor, it is absolutely necessary. All other components can be replaced building materials.

The disadvantage is said to be that it takes a special tool and the ability to handle it for the construction of such a structure. A longer period for the manufacture of the system, as opposed to electric type, especially when using the classical concrete screed.
Mount system water floor heating on the forces of each. You only need to do it according to the rules. Then the effect of its use will definitely be the most effective. System security is ensured of its quality.
