Installation of water-heated floors, without a concrete way by Alexoth
Installation of the optimal source of heating – the vital issue which owners of private houses and apartments more often face at arrangement of system of heating. Any design decision, whether it be radiator heating, underfloor convectors, electric or water heat-insulated floors, has the pluses and minuses. Therefore the choice in favor of this or that type of heating is defined first of all by its expediency, technical possibilities of realization, efficiency, profitability, reliability and convenience of installation.
One of the most comprehensible and effective variants of heating – the water heat-insulated floors mounted “dry” (without concrete) in the way. In the present publication speech about technological features of installing the systems without concrete will go.
Elements of the whole
The system of floor water heating mounted by a “dry” method. Represents the difficult mechanism. Its basic knots – a heating contour, polystyrene insulation plates (plate) with dredging for pipes, profiled metal plates in the thickness of 0.4-0.5 mm. A regional tape, a collector (comb). The three-running valve, the circulating pump, the thermostat with portable gauges, timers.
In turn heating contour consists of the branched out network, the pipes laid and fixed inside polystyrene of plates (or between lattice boards) in the form of loops. Plates use for uniform distribution of heat on all surface of a floor. The regional tape compensates temperature expansions of the heating panel. The collector is intended for connection of several working loops and distribution in them the heat-carrier in which quality use water, the solution propylene-glycol is more rare. Quantity of exits of a comb (from 2 to 12) select depending on quantity of working contours.
The pump provides circulation heated waters in system. It choose taking into account the area of heating, capacity of a copper, volume of the heat-carrier, hydraulic resistance of system which is caused by number of working loops, stopping armatures, length and diameter of the pipeline.
Water heat-insulated floors function in an independent mode (the heat-carrier moves on the closed contour), sometimes them connect to the centralized heating if in the house special struts of the big diameter (50-60 mm) are provided. If those are not present. Establish special heat knot. In the first case as an energy source traditionally use a copper, solar collectors, thermal pumps are more rare. As the heat-carrier temperature in a working contour should be supported within +35… +45 • ?. System of underground water heating supplement three-way with the valve which mixes with the leader from a copper a pipe the heat-carrier from a return pipe, or establish a copper with low-temperature an operating mode.
For cases special
“The dry” technology of installation is alternative to traditional pouring of a heat-conducting contour of water floors cement-sandy coupling with application of softeners. It is less extended. Than “the wet” way It speaks in high cost of such system. So. One only heat distribution a metal plate in the size 1.0 x 0.12 m (the area of 0.12 mg) will manage about 7 dollars. For heating of a premise by the area of 20 square metres it is required about such 160 plates, and already 1 thousand dollars.
To non-concrete to a method resort when the coupler device is technically impossible. First of all it concerns private houses with wooden interfloor overlapping which are not calculated on high loading. A number of advantages is inherent in a “dry” way. First. On its realization it is necessary much less time. Such water floors are ready to commissioning practically right after installing of a finishing covering. That it is impossible to tell about the concrete method, 25 days demanding a minimum for hardening.
One more plus of dry installation – rather low raising of level of the floor, not exceeding 50-60 mm. In turn at pouring of pipes by concrete the thickness of a design varies from 70 to 300 mm. That is rather notable, especially for apartments with low ceilings.
