Concrete slabs arrange a warm water floor filler in the cement screed. Concrete foundation waterproofing lining is laid a layer of insulation and a mesh. Pipes to the carcass cells attached by clamps, fasteners or special steel wire. Atop the tubular contour for uniform distribution of service load floor covering, reinforced coupler is also satisfied, if necessary.
Lightweight foundation that combines the functions of a heater and a frame - folding or special profiled mats made of extruded polystyrene. In the former case a tube is fixed on the substrate surface with special clamps harpoon lugs or mounting rails. On profiled mats circuit loop tightly fixed boss, additional fasteners are not required. An improved version of profiled mats are coated with a waterproofing system and equipped with locking projections.

The temperature was controlled by a forced mix with streams: part of the return heat transfer medium flows into the supply conduit. Mixing units installed between the boiler and distribution manifold.
There are models of gas appliances that are built-in floor heating circuit: Automatic operation in "warm floors" mode restricts the flow temperature at the outlet from the boiler to 45 ° C. Operation of the conventional gas boiler in floor heating mode reduces the efficiency of operation of the unit.
Long burning solid fuel in wood burning distinguishes complicated adjustment mode. The apparatus of underfloor heating systems with a heat generator for solid fuels, in addition to the circulation pump, the installation requires buffering capacity. The coolant in the floor heating system is taken directly from the pressure accumulator.

Wiring diagrams warm water floors in apartment
Primary or secondary low-temperature circuit of underfloor central heating systems in apartment houses plan the development of the project. To make changes in the radiator heating circuit apartment house prohibited housing law. The temperature of the radiator circuit above required parameters for underfloor. Unauthorized change of direction, diameter and length of heating obschedomovogo riser leads to unbalance the system and disturbance of the thermal regime in a building.
Specialized organizations to make installation of underfloor heating from the central heating in apartments during the construction of the building. The principle of the device of underfloor central heating in the flat connection method distinguishes the low-temperature circuit. The coolant enters the water underfloor pipe separately from the radiator heating, standpipe. Hot water for floor heating preparing a heat exchanger, which is installed in the central heating, thermal node apartment building, or directly in the flat consumer.
Scheme tapping of warm water sexes radiator central heating circuit 1 - the ball valve in the inset feed line; 2 - ball valve to reverse the inset; 3 - strainer; 4 - check valve; 5 - a three-way mixing valve; 6 - the bypass valve; 7 - circulation pump; 8 - the valve on the return manifold outlet; 9 - shut-off valve at the feed inlet manifold; 10 - a return manifold; 11 - the case of the supply reservoir; 12 - Ball valves on return pipe loop; 13 - Ball valves on the supply circuit; 14 - vent valve; 15 - drain valve; 16 - radiator
Theoretically, change the length of tube without compromising the thermal regime in adjacent flats may last (in the direction of coolant movement in the riser) consumers. If the heat is distributed from above, the floor heating on the ground floor does not affect the heat apartments located above. However, the operating pressure supply pipe at the bottom postoyachnoy wiring may not be sufficient to circulate the outdoor upper deck contour.
In the absence of initial design data for floor heating device in an apartment house additional circuit connectivity check with the supplier of thermal energy and control company. Resursosnabzhayuschie organizations authorize the device is warm semi-floors, with sufficient reserve capacity of the existing heating system.
