The basic design of the floor warm water
Conventional floor construction warm water involves multiple layers stacked in sequence. The thickness of the formed cake should be 8-14 cm at the maximum load on the slab of 300 kg / m².
If the base serves as a concrete slab, Warm water floor includes:
waterproofing layer often formed using a polyethylene film;
damping tape is placed around the circumference and made of a heat insulator strips or special materials with an adhesive base;
heaterSelected taking into account the location of buildings. The most popular is extruded polystyrene thickness of 5-10 cm;
reinforcing mesh;
water loop;
screed.
Structure of floor heating with concrete screed
If warm water floor unit is carried out in a private house, hosted Pie includes:
soil layer thickness of 15 cm;
gravel layer thickness of 10 cm;
a sand layer thickness of 5 cm;
rough screed;
waterproofing layer;
damping tape on the perimeter;
insulation;
reinforced screed heating circuit.
The number of layers in a private home increases significantly
System without tie layer consists of a vapor, waterproofing, polystyrene plates, heat reflecting plates, pipes and sheathing of gypsum fiber board.
Completing the elements that must be available
Warm water floor consists of:
hot water boiler;
injection pump, if there is none in the composition boiler;
ball valves at the inlet boiler;
distributing pipes;
collector, allowing to adjust the heat flux. With the aid of two couplers one main line connects several floor heating loops. One allows to distribute hot water, the second - to assemble the cold;
pipeMounted on the floor surface. To manufacture the heating circuit is preferred to use products of cross-linked polyethylene, or polypropylene. The latter should be reinforced to ensure adequate strength characteristics;
fittings.
It provides a special niche for the collector
Advantages and disadvantages of the water floor heating
The main advantages of water are floor heating:
aesthetics. heating elements are located under the decorative coating, and therefore are not able to degrade the appearance of the premises, executed in any style;
security. There is no fear of burns when accidentally touching the heating system;
economy. When compared with warm water floor heating system, consisting of radiatorsSavings can reach 20-30%;
comfort. On the warm floor comfortably move even in the bitter cold, which is especially important for families with young children. In this case if the floor temperature is + 22 ° C, then at the level of heads - + 18 ° C. at radiator heating occurs circular circulation of air masses: heat rises first and then falls, cooled down to the floor. As a result, the person feels uncomfortable;
long service life. System manufactured with quality materials, able to serve half a century;
uniform heating of the premises;
possibility changing the degree of heating.
The appearance of the flooring remains constantOn the floor comfortably walk barefoot
The disadvantage is:
the complexity of installation in an apartment located in an apartment building;
time-consuming installation;
the complexity of the repair works.
To repair the pipe, it is necessary to raise the floor

Calculations before installing
So that when the installation work no difficulties to purchase materials needed to perform the calculation should be their number. To do this, a detailed diagram drawn with the contours of the future of the water floor heating.
To calculate the required number of stacking scheme need to know
Attention! In places where you plan to install furniture or plumbing, pipe laying irrational. Warm water between the floor and the wall should be at least 30 cm.
In the development of warm water floor configuration, be aware that:
contour with a cross section 16 (20) mm can have a length of more than 100 (120) m. Exceeding this parameter can trigger a decrease in pressure in the system. This length is sufficient for room heating, with an area of 15 m²;
If your system has multiple paths, they must have a comparable length;
tubes must be placed in increments of 15 cm. For homes, which are located in regions with cold winters, a step should be reduced to 10 cm.
Selecting the step depends on the structure location

"On average, when laying pipes with a pitch of 15 cm / m² of 6.7 m is required, at step 10 cm / m - 10 m."
When calculating the thermal floor parameters should also consider the use of the thickness of cement screed. Each additional centimeter screed 5-7% reduces the heat flow.
Tip! To calculate bigger slowness of the heating circuit of warm water floor, the area should be rooms divided by the received step, then the value obtained is multiplied by the correction coefficient (1,1).
To calculate the required number of rooms you need to know the area and the step of laying
