Radiant floor: advantages and disadvantages
Water underfloor heating is used in the private sector, with independent heating. The pipes receive heated water, which heats the floor surface. Warm air moves evenly, creating comfort and comfort in the room.
warm floors have several advantages:
- Savings - floor heating device will reduce the consumption of energy, the heating is to a temperature of 35-40 ᵒS.
- Will create a comfortable heat, air flows will be evenly distributed throughout the room.
- Safety and durability of operation excludes burns.
- Application of almost any surface coating.
- Temperature control - it is possible to regulate the heat in the house.
The shortcomings of the warm floor include labor and costly installation. Laying pipes, it is necessary to raise a little a covering that will reduce distance to a ceiling. The heating of the room will last from 2 to 3 hours, depending on the size of the room and the installation of heating elements. You can cover the water system with any material. Ceramic tiles will be an excellent option. It has high wear-resistant characteristics, environmentally friendly, does not emit toxic substances with rising temperatures, has a good heat capacity.
In the winter months, you can walk on ceramics with bare feet.
You can cover the floor with a laminate, but it must have special characteristics. It is necessary to buy a quality material with good conductivity of heat and a mark "for floors with heating".Choosing linoleum for the water floor, adhere to some criteria. The material must be wear-resistant and with good thermal conductivity. A cheap option on a rubber basis is not desirable to apply. It is impossible to heat the floor more than 28 ᵒС, the coating will start to release harmful substances, which can negatively affect the health of the household. Select linoleum should be on a fabric backing. Sometimes use carpet, with a special mark. It has toxic additives, so the heating temperature should not exceed 26 ° C.When choosing a coating, it is necessary to study its composition, characteristics, pay attention to thermal conductivity and ecological purity.
Warm water floor with your hands: the calculation of the material
installation and assembling of the water system can be carried out independently. This design implies several layers with different fillings. The system itself consists of pipes laid out according to a special scheme. There are several ways of laying out water heating.
- Concrete screed filled with installed pipes;
- Arrangement of elements in grooves made in expanded polystyrene;
- Stacking in wooden trenches( most often used in wooden structures).
Various kinds of pipes are used for water heating. Ideal option will be a system of metal-plastic pipes. They hold a good shape, are easily installed and have democratic prices. It is possible to use elements from cross-linked polyethylene. However, it is difficult to work with and give the required forms, when hot water arrives, it straightens. Copper pipes are considered an expensive material and require an additional protective layer.
An important point in the installation of a warm floor is its calculation.
The length of the contour depends on the diameter of the pipe. For elements with a diameter of 16 mm, the maximum length is 70-80 m, 17 mm pipe - 100 m, 20 mm - 120 m. If you neglect these standards, the pressure in the pipes will be poor, accordingly, the heating of the room will suffer. For large areas, the system is made up of individual contours. Before starting calculations, it is necessary to determine whether the water heating will be the main or only floor heating. In the first variant, the distance between the turns should be from 15 to 20 cm. With simple heating, the distance can be increased to 30 cm.
Algorithm for calculating the length of pipes:
- Determine the square of the room - S;
- We assume the distance between turns - N;
- Take into account the coefficient for the bends of pipes - 1,1;
- We calculate the length by the formula: L = S / Nx1,1.
For example, if a room has 20 m2 with a pitch between turns of 30 cm, then it will take 20 / 0,3х1,1 = 73,3 m of pipe. If the collector is at a remote distance from the room, measure the path and add the figure to the calculated footage. Obtain the desired length of the pipe. In the same way the calculation of each contour is carried out, after obtaining the desired figure, sent for purchase.
How to make a heated floor with your own hands: accessories
The system is not limited to pipes alone. It will be necessary to purchase a boiler. Experts recommend buying gas with the possibility of using in the summer time for hot water. When choosing an aggregate, one should pay attention to the power comparable to the quadrature of the house. It is possible to install a boiler working on electricity, coal and even wood. The most economical will be the operation of gas equipment.
You need a mixing unit that consists of:
- Air Taps;
- As well as various fittings and a circular pump.
First you need to install a boiler and a collector, which is best entrusted to specialists. You can do the work yourself using the attached instructions. Then you can fix the floor. It is necessary to prepare the base of the floor. It should be clean and as level as possible. If there are large differences, it is recommended to make a screed. A larger takeoff, more than 5 mm, can affect the increase in hydraulic resistance.
Installation steps and underfloor heating
After the preparation of the surface, proceed to the main works consisting of several stages. The thickness of the overall layer can reach 20 cm. Work begins with the installation of waterproofing material or use a conventional film.
Assemble the water floor from different layers:
- Waterproofing layer;
- Damper belt;
- Reinforcing mesh;
- Heating pipes;
. When laying the joints, they are glued with adhesive tape, the material is put on the wall with a margin of 20 cm. The damper tape is laid out around the perimeter of the room. You can make it yourself by cutting the insulation on the strips or buying a self-adhesive option. In both cases tape is glued to the wall. The next stage of work is the installation of insulation.
Sheet material is overlapped. Places of joints can be glued. It is much more convenient to work as a heater with ready grooves for pipes.
The reinforcement is carried out with a special mesh, which will serve as the basis for fixing the contours. The armature is connected with each other by wire. The distance of the cells is selected, depending on the contour step.
From what and how to make a warm floor: the order of laying
You can arrange the outlines in different variations. Metal-plastic is well bent. It is necessary to make a bend in several approaches. Polypropylene pipes are bent by heating or special fittings are used. Any way of laying has positive and negative sides.
- Snake fitting. Simple method, easy to assemble. The main drawback is the temperature difference between the beginning and end of the contour. Scattering by snail.
- . The variant is more complicated, but the floors will be warm around the perimeter, the supply and return of water are carried out inside each other.
- Combined method. Applied most often. The middle is laid with a snail and a snake is passed around the perimeter.
Each circuit must be adjusted separately, not moved from room to room. An exception may be a small bathroom and toilet. The contour is designed for an area of not more than 40 m2.If necessary, several elements are used in the room. To fix the pipes use special clamps, steel wire, bracket-harpoons, fixing tracks, special planks for placing pipes, mats with grooves, between which the elements and distribution plates are laid, which are used in wooden buildings. When all materials are purchased, you can proceed with the installation of water heating.
Underfloor heating: laying of pipes
After preliminary works of floor insulation and laying reinforcing mesh, it is necessary to spread the pipes and fix them on the fitting, and after installation and connection, it is necessary to make a check crimp. For this, it is better to use an air compressor.
- It is necessary to rewind 10-15 m of pipe, put insulation on one end and put a fitting that will then connect to the collector.
- The selected layout scheme serves as a guide for the location of the pipes.
- After laying the track in 10 m, begin its fastening to the fittings. The pipe should lie on the surface without distortion.
- After filling the space, the pipe returns to the collector, the fitting is put on.
The rest of the circuits must be assembled in a similar way. To prevent damage to pipes, move around the floor on specially designed paths from plywood or boards. Next, you need to connect the circuits to the collector.
The distribution unit implies some functionality: it increases the system pressure, distributes the uniform flow to several circuits, regulates the heating temperature.
For water pressure testing, a hose with tap water is connected to the supply manifold, and a pressure test pump is connected to the other outlet. On the unit, overlap all contours, leaving one. Then give water and control the air outlet. When the liquid has gone clean, the faucet is blocked. The resulting leakage is eliminated. Each circuit must be checked. After the manipulations, the water is blocked. Complete the process of collecting the warm floor with concrete pouring or special flooring.
Self-contained hot-water floor device
Additional reinforcement is required for concrete pouring. You can use both metal and plastic mesh. The screed is carried out in 2 stages: a dense concrete layer is applied, the liquid is brought to a finish coating. Before starting work, it is necessary to install beacons and conduct lines, which should be oriented in the process of pouring.
Screed consists of a mixture:
- Sand of river;
- Cement M400-500;
- Fine crushed stone Ø20-50 mm;
- And ordinary water.
Warm floors require adding plasticizer to the solution. To simplify the mixing procedure, it is recommended to use a concrete mixer. Prepared mixture is laid out throughout the floor, focusing on the lighthouses. At the end of the work, it is necessary to organize the expansion joints to reduce the formation of cracks.
Before making a final screed, the seams are filled with sealant.
The floor will dry for a few weeks. After this, make a finishing fill, preparing a more liquid solution without crushed stone. You can use the floor. After complete drying, you can make a floor covering.
Underfloor heating from metal-plastic pipes with their own hands
In wooden houses, too, do water floor heating. Use an easy installation of the heating system, which allows you to place the heating structure is relatively strong, which will prevent the destruction.
Assembly technology :
- Lay the heater between the floor ladders;
- Then the strips of particleboard or plywood with gaps for pipes are placed;
- Next come the distribution plates, in which the heating elements will be inserted;
- Pipes are laid;
- Mounted layer GVL, for better heat distribution;
- In the end there is a facing covering.
If the flooring is laminated, the gypsum board can not be laid. When choosing a material, you need to make sure of its technical characteristics. Properly assembled wiring and competent operation will allow to serve the warm floor for a long time.
Commissioning of floor heating
After final installation, the heating system must be gradually used. Start heating from 20 ° C, raising the temperature several times a day, bringing it to a comfortable state.
If the coatings are made of laminate and wood, the temperature of the circulating water is increased and lowered gradually. This will extend the life of this coating. Heated floors in wet rooms are adjusted to 31 ° C, in dry to 26. Do not exceed the temperature of hot water over 45 ° C.
