Radiant Floor Heating: types, devices, plus what better

When you have to make repairs apartment or house, stop your choice on the design of warm water floor, where the heat source is hot water. It improves the quality and efficiency of heating, reducing cash costs for housing content.

Installation of water sex is complicated, but such work is carried out independently in compliance with the rules and process sequence.

Types of warm water floor

By selecting heating structure, consider the type of installation of the room, coating materials, strength bearing structures and requirements.

Classical variant - concrete technology, when mounted in aqueous floor screed of concrete with a pre-stacking insulation and moisture barrier.

There is also a grazing system of wood or polystyrene. Stand rack and module types. For mounting rack designs using edged boards, and for modular - each sheet (modules).

After laying the foundation sutured chipboard or plywood sheets and have to be Finish coating of linoleum or laminate.

Apparatus water underfloor

The liquid moving along the pressure conduit is diverted to the heating circuit, during the passage through which gives up heat to the floor surface.

The cooled water is returned back, acting in the boiler and then heated to the desired temperature.

The base set special limiters connecting the floor temperature with the volume of water in the heating circuit (the base is heated, creating an optimum microclimate).

Characteristics

Floor structures made of wood consists of the elements:

• basis basecoat;
• Edged board, OSB, particle board;
• aluminum distribution plate;
• pipelines for coolant;
• substrate for laying the foundations finishing;
• team tie GVLV;
• Finish coating.

Styling define the appropriate option:

• modular type formed from prefabricated elements;
• pinion type assembled from prefabricated boards.

To apply modular sheet from polystyrene or chipboard with grooves for the installation of pipelines. The foundation is laid on the joists, which are mounted in steps of 60 cm on the old foundation or subfloor. The interior space is filled with a heat insulator.

Next to the joists are fixed modules, stacked pipes and the system is connected to the hot water supply. The modules are expanded heat-spreading of the metal plates with grooves, which are attached plastic pipes.

Slatted construction is based on the use of boards in the thickness of 28 mm, which are stacked on each other a distance of 20 mm (to form grooves, which are mounted in pipes). Modular floors are used less frequently, but are durable and reliable.

Scheme stacking warm water floor:

• base;
• insulating layer;
• reinforcing mesh;
• heating pipes;
• pouring concrete;
• a substrate for final coating and the top layer (laminate flooring).

Warm water floor is used in two-pipe heating forced by circulation of coolant and collectors for wiring to equipment.

It includes the following elements:

• Boiler room and the boiler group. Create a non-stop supply of coolant to the risers (arteries supplying heating). After passage through the heating apparatus, the cooled coolant is returned back on line.

The boiler runs on liquid or solid fuel pellets, from a heat pump, energy and so forth. The structure includes a boiler pump, boiler safety group and expansion tank;

• Radiator manifolds for measuring pipes and heaters;
• Inverse and the flow that is fed radiator manifolds, mixing unit with the manifold floor heating. On each floor mounted cabinets with collectors.

A suitable embodiment of the heating structure - with a compound of the boiler entering the pumping system. Due to the fact that the heating of the coolant comes to 35-45 C in order to reduce this value is used mixing unit. Established a two- or three-way valve.

Then provide for underfloor heating pipe connected to the special collector with exits to the contours, thermostatic valves, and consumable regulators. In the supply and return conduit are placed taps (for possible off operating circuit).

Recognize the variations circuit installation:

• snake. The technology is simple, but there is a drawback - the difference between the temperatures at the end and the beginning of the loop. Moving from the supply reservoir to the contrary, the heating medium cools down. The method is suitable for installation in the boundary areas;
• snail. The technology is complex to implement, but provides the same temperature;
• combined version. Such stacking is used often in her extreme zones stacked snake, and the rest - a snail.

Pipes for warm water floor:

• of metal. They are easy to install, keep their shape and have a low cost;
• XLPE. They work inconvenient because of the heating pipe made of this material are straightened;
• of copper. Tubes are expensive, must be closed with a protective layer due to corrosion.

Pluses water underfloor heating

• economy. Heating large areas at lower cash costs and on water heating costs;
• uniform heat distribution and climate control;
• aesthetic design, the walls are no pipelines radiators. Therefore, designers may be implemented different projects. In addition to the bathroom floor heating can be used water heated towel rail;
• adaptation to any source of energy, materials and constructions floors;
• durability;
• security and the absence of the electromagnetic field;
• readiness for laying all variants of the finishing coating (laminate, linoleum flooring etc.);
• operative setting.

When laying wooden structure plus - prevention of moisture and rapid warming.

An advantage of the concrete screed is securely installed, the strength and integrity of the tubes, but the cost of such floor would be higher due to the concrete casting.

Minuses

Water floor is suitable for decorating private homes and cottages. For apartments with central heating facilities, such a system is not suitable, as will need to collect a lot of documents for obtaining a permit.

Other disadvantages include the design:

• The need to perform complicated calculations for installation;
• We need to raise the level of the floor for a few centimeters, reducing the height of the door.
• In the concrete floor will have to open the base of the leak. The system features a large weight and is not suitable for old objects.

Therefore, pre-read advantages and disadvantages. It is better to install the floor in a newly built house, making the necessary calculations when designing, thus reducing installation costs.

How to choose

To choose a quality water floor, pay attention to the components:

• overlap type;
• Finish base;
• coolant temperature;
• indoor climate and so forth.

According to snip requirements, the minimum thickness of the screed is 20 mm, but if the reinforcement is not applied, the rate increases to 40 mm (tube diameter 25 mm).

Above tubes large thickness does not exceed 55-65 mm in premises, showrooms, fitness clubs, restaurants - 200 mm, for hangars and industrial shops figure rises to 300 mm.

On the collectors must be installed, adjusting (for smoothly changing the heat supply to the heating circuit) or shut-off (to shut off the circuit of the heating) taps. The manifold has an air valve and drain tap.

The structure of the collecting enclosure includes a pair of combs with valves. Design and develop it with heating, in accordance with the number of connected loops. Mounted above the level of the structure, from which extend down the tube.

The collecting group placed thermostats.

In calculating water floor captured linear parameters of rooms, and insulation material covering, form finishing the base, the parameters used and the type of piping, the temperature of the incoming coolant.

Using these figures, the heating circuit is determined by the length and pitch tube layout screed.

aqueous floor temperature of 29 C for kitchen, living rooms and corridors. Exception - children's rooms, where established a special operating mode. Near the windows and outer walls (at high heat loss), the temperature should be 35 degrees, and in bathrooms to 34 C.

Properly designed and set design will save 12% of the released energy by preventing heat loss. Additional energy savings provide automatic controllers.

First the heat loss from the house, are calculated based on the number of doors and windows, insulation of the nature of the roof, floor and walls. By default, the figure is 40-300 W / m².

The highest rate seen in rooms with thin walls of brick, without insulation, and the lowest - with excellent thermal insulation and double-glazed windows.

Heat losses are also compared with the normal capacity of the floor heating. It is considered that is the distance between the walls and the substrate edges.

That is, the total area of ​​the system can not exceed 70%, since it is necessary to take into account the placement of household appliances and furniture in the room. Because of the low power and limited space design can not heat the room completely.

We calculate a constructive power, the level of heat loss (heat loss multiplied by the area on indicators). If the index exceeds the heat, the use of irrational system.

What is radiant floor heating is better

Components of the best water underfloor heating:

• a concrete slab;
• waterproofing;
• Damper tape;
• insulation;
• reinforcing mesh;
• pipe and coupler made of concrete.

Waterproofing may be performed by a polyethylene film or special materials. Insulation is selected depending on the climate and floor insulation.

The contours fit snail. In the field of large accumulations of the closed heat-insulated pipe.

Exploitation

Warm water floor helps to create comfortable living conditions. To create an optimal climate parameters are supported:

• Water temperature 23-27 degrees;
• air temperature 26-30 degrees;
• kindly include the heating system due to the slow heating, when the occurrence of the first cold;
• for ease of maintenance and automation of heating and temperature control, automatic thermostats are set.

Operate the water floor is possible throughout the year, shutting down part of the structure. Applied branches, passing under keramoplitkoy, which remains cool even in the summer.

The system is stable for the installation of furniture, equipment and other interior items, it is not afraid of overheating. But the temperature should not exceed 55 degrees, which will be dangerous for the tube material and the concrete screed.

Guarantee

Durability depends on the quality of completed materials, innovation technology, professional laying systems and the correctness of the project.

If the warranty on the work electric underfloor calculated for a period of 25 years, on the water system will be more, the duration depends on the manufacturer's tube and pipe quality.

The warranty on the equipment and materials provided by the manufacturer. It is important to observe the technical specifications. Check out the list before using.

On the wall mounting warranty is provided by the installer. Warranty will be deemed in compliance with relevant operating conditions, which are listed in the annex to the contract.

The warranty period for work performed is from 12 months to 5 years from the date of the preparation and coordination of the act made work. Its duration depends on the used components.

After the expiration of warranty service may be an agreement prolonging maintenance services on individual conditions.

When operating the water sex draws attention to its effectiveness (not to lay under the furniture, cabinets, sanitary equipment), insulation slabs or foundations 1 floor.

Faults and repairs

Water floor structure is simple in structure, because of what little reason to fault. The heating may deteriorate as a result of:

• lack of noise in the circulating pump power is supplied;
• lack of functioning of the system. You should check the distribution board on each circuit, where the shut-off valves should be in the open position;
• air intake.

Troubleshooting:

• Removal of air from the heating structure. floor heating operation can be incomplete even if quality installation.

Airing main problem is due to the sharp pressure drop in the heating circuit, excessive heating, leakage and leaking connections, improper installation.

May incorrectly installed collector pipe with a slope, missing taps for removing excess pressure or at an initial start-up of the collector unit is not pumped air. The system will not be heated due to the small thickness of the pipeline.

The problem solved by the overlap of one loop and leaving, after which each branch is run separately.

In this case the circulation pump is turned on at low speed increases in the system pressure to 1 kg and while operating in this mode, at 55 degrees.

By reducing the functioning of the flowmeter structure is improved. To automatically remove the air from the pipe separator can be used.

• Setting up the system. For proper settings should explore principles of manifold directs the flow of the waste and the warm liquid. Typically, the work circuits is adjusted in accordance with the balancing table.

In this case, the cap is removed from the valve and close it. According to the table define the speed of each circuit by turning the valve as many times.

• The low temperature due to the insufficient capacity of the boilerTo be cleaned, or to carry out preventive maintenance to check the temperature sensors.

Heat dissipation is reduced in the presence of furniture and carpet or because of poor insulation (you may need modification and installation of high-quality thermal insulation).

• Uneven heating. If bleeding of the system was carried out, but the floor is not warmed, the reason may be illiterate or no vapor barrier. Check this factor can be adhered to the floor of polyethylene.

If condensation appears on it a day later, the system need to shift.

• Mechanical damage (for paving). First off water, protects the damaged area is cleaned access to the pipeline.

Cut injury site, unfolding the ends of the scan, the pipe is worn clutch and press-fixed press jaws. Checked the tightness of internal hydraulics.

• Improper installation.

Improper installation floor possible with understated door openings, improper positioning collector installation according to "snake" technology, larger pipe arrangement step, heat incorrect counting.

It is possible at unprepared ground insufficient insulation thickness, short length pipes.
