Make a warm floor heating from their own hands

Warm water floor - it's comfortable and convenient, especially if they do not require the installation of the boiler.In homes with a radiator heating can be connected to the underfloor heating system - it will make the water warm floor without any extra costs.

Project Execution

to perform underfloor heating, powered by the heating system requires a number of conditions.The heating system should be equipped with a circulating pump.In his absence, and easier to spend money to install the pump, you perform a gravitational system with a sustained gender bias circuit.The system can be both single-pipe and two-pipe.In a one-pipe system, underfloor heating feeding tube connected after the circulation pump and the back - before the pump.

also necessary to calculate the length of the loops.For two-pipe system, it should be no more than 50 meters, a single pipe - not more than 30 meters.If the space heating circuit turns more necessary to divide it into several loops arranged in different zones or in parallel.

Preparation floor

To avoid heat loss and heat the slabs, is necessary before installing the heating circuit to perform the preparation of the surface sub-floor.

1. If on the floor already has a floor - it must be removed, cracked grout trowel and level the floor surface using mortar or a thin layer of pure coarse sand.The floor surface is required to check the level using the absence of distortions - if the underfloor heating circuit to be laid unevenly formed areas with stagnant coolant that impair heat transfer.
2. around the room, as well as at the junction of the heating circuits must be installed damper tape.The tape is available different widths, with the adhesive layer or without it.The width of the belt must be chosen so that it was above the calculated height of the concrete screed.fastening method selected depending on the wall finish.To smooth walls tape can be stuck using an adhesive layer.For rough surfaces damper tape securing the dowel-nail for quick installation.The tape is needed to ensure that when the heating-cooling floor screed fracture did not occur.

3. After that the floor is necessary to lay a solid insulation, which does not allow heat to go down.This may be in the form of extruded polystyrene plates or rolled foiled polyethylene foam coating.Plates are placed end to end, without allowing gaps and crevices.Roll materials as laid end to end, and the joints are glued metallic tape.Roll materials due to the small thickness is used rarely, only in the event that because of the small height of the room to use thicker insulation is not possible.Above the insulation layer stack of plastic film 200 microns thick - it is necessary in order to create better conditions for the drying of the concrete screed and concrete eliminate leakage.

4. On the floor is laid armature.It can be reinforced with a mesh of 10 cm from the cell, or a grid of 8.6 mm rod, connected to the ground wire crossing.The grid is laid on the plastic rail to create a gap between the armature and the base.
5. to perform the warm water from the floor heating suitable special polystyrene boards with bosses - they are intended for laying the water circuit and do not require the guides.Please note that during installation of polystyrene with bosses need to use plastic pipes instead of polyethylene and fittings laid after the laying of the water circuit.

Laying water circuit and fill screed

After preparing the floor is necessary to lay the water circuit of the metal pipes at a pre-thought-out scheme.You can also use polyethylene pipe threaded.Usually two ways to apply stacking "snake" and "snail".Stacking "scroll" more profitable - circuit comprises less angles, with the colder return flow pipes are directly next to the hot, thus avoiding the so-called "zebra" - areas of warm and cold floor.water circuit pipes are usually placed with a pitch of 15 cm for the southern regions can be used, and a step of 30 cm. If you want to make a floor on any part of a warm, stacking step on it can be increased.The diameter of the water circuit of pipes is selected smaller than the diameter of the main pipe, or the pressure in them will be insufficient.

1. water circuit pipes are laid in accordance with a pre-drafted plan, starting from the distribution center.To connect pipes leave some margin.Laying pipes produce a single loop without joints, to avoid possible leaks.Doing this is more convenient together: one puts the pipe, the second of its ties up to the fixture with plastic clips or establishes between the lugs.

2. After the end of the pipe layout is output to the distribution point, fixing in the joint between the wall and the floor with the help of special metal casings.
3. Turn on the contour of the floor heating using a special connecting fittings to the distribution point and fill the system with water or air.Check for damage to the pipes.

4. screed is best done on a system filled with air.For screed concrete stamps used 200 fine grain filler.Concrete is poured onto the prepared substrate, put beacons from boards and smooth with the help of rules.The height of the screed must be such as to completely cover the pipe and water circuit valves 5-6 cm. Thicker screed worsen dedication, and a smaller thickness can result in damage to the pipes.screed surface can be lightly sprinkled with cement through a screen - this will make it more durable.Dry screed takes about 3-4 weeks before you can mount a decorative floor covering and load it.
   

   next step - a screed

Underfloor heating in the room - the perfect base for any styling Finish: tile, linoleum, laminate.In floor heating with a water circuit, there is one drawback - it has a considerable height, about 10 cm If the ceiling height does not allow for floor heating by heating the device a concrete screed, you can warm water floors with modular structures or power using infrared mat..
