How to connect Underfloor heating with his own hands
The contents
In recent years, an increasing number of people seeking to establish in their homes insulated floors. Central heating system is not always able to heat the room, so the owners try to achieve the best effect on their own.
One way of warming an apartment is the installation of warm floor. Laying the electric floor just seems a complicated procedure, it really is possible to do with their hands.
Types and selection of electric floor ↑
- There are several types of warm floor electric:
- cable type;
- cable warm floor with the base;
- film infrared.
Cable warm floor ↑
A warm floor is convenient because it can be installed as a private house and multi-storey. This floor is much more easy to install than water, as its installation does not require connection to the pipeline – enough to pave a thin electrical cable and connect it to the network. The system is more simple and in control, it’s easy to track the rise and fall of temperature, it is easy to adjust if necessary. The advantage of this type of floor heating is the fact that it has a timer and can easily heat a small private house.
Gender, on the basis ↑
Warm floor on the base is a fine mesh Mat, which is fixed to the wire. This is the easiest type of sex from the standpoint of installation work, as the heating element already attached to the mesh. This system is best suited to laying under tile, in this case, you don’t need the coupler. However, this floor should not be laid in those places where the furniture will stand.
Infrared floor ↑
Infrared floor – the best but most expensive option of warming. It is a thin film with a specific filler, in addition, it allows you to save up to 60% of energy consumption. Gender does not change the height of the room, the film thickness is only 0.5 mm.
Choose a floor type you need based on the features of your home. When choosing guided by the recommended three factors:
- the electric field should generate a sufficient amount of heat;
- gender needs economical use of electricity;
- to be easy to install.
Any system, in addition to infrared, comprises cables which are laid in the wall, and cables, which is itself heated. All the wires are divided into two types – self-regulating and resistive. Currently more commonly used self-regulating, because they are deprived of the shortcomings of the resistive cables. They are more reliable, have a great life. However, self-regulating cable will cost you several times more expensive than usual.
How to calculate the amount of cable for floor ↑
Before buying the cable it is necessary to determine the capacity of the entire heating system. For each room it will be different. The calculation is carried out for 1 sq. m. In particular, for bedroom the required power is 100 W/ sq m for the kitchen or hallway – 150W for bathrooms, power can reach 180W and balcony – 200 watts. Knowing these parameters it is easy to choose the optimal number of wires for floor heating.
Keep in mind that the calculation does not take into account the space occupied by furniture. The reason for this approach is that the floor area covered by furniture, there is too much consumption of electricity, in addition, there may be overheating.
The first phase of work – preparation of the Foundation. Usually laying the electric floor is performed during the repair, we must start right after the rough work is over – flooded the ceiling, plastered the walls, made of the screed. After these works the floor is always covered with a layer of cement or dust, remnants of plaster, so it should be treated with a staple. The floor leveled with self-leveling layer.
Important point – the concrete surface should be smooth, without differences in height, otherwise possible short circuit and failures in the floor.
The next step is to install the insulation. The first layer stack of reflective insulation, do it need a reflective surface up. The insulation is necessary to ensure that when the heating wire all the heat went up, not heated concrete base. Insulation helps to minimise heat loss. This material blocks the flow of heat, and sends them to the surface.
The type of insulation depends on the room in which it is placed. In a building on floors, starting with the second, you need to put foil, a rolled material for insulation. The material is laid out, carefully dock and fix with a stapler. The result secured with special adhesive tape.
If the floor is laid in a private house or on the first floor of apartment buildings, as insulation use foam. Over the insulation fit insulation, what is done with the sunset on the wall. To secure its use edging tape.
The next stage is the beginning of laying the floor. For starters, you set the thermostat. In the wall in which you plan to place the mounting box, hollow out the hole. The optimum height for him – 60-100 cm To the hole down the wiring and grounding.
The thermostat will go directly from the cable heating elements. Cable provided corrugated tube, inside which is installed the temperature sensor for control of heating. Corrugated tubing should go straight to the installation site to the connecting cable. It is important that the corner between the wall and the floor and the tube is smoothly bent and not broken. Otherwise, it will damage the temperature sensor.
Next, go directly to the installation of heating elements. The technology requires to lay the cable only on the free from furniture space, it is necessary to retreat from the walls of 5 cm from heating devices 10 cm Wire is just connected and laid out on the floor evenly, pre-occupying it with segments of adhesive tape. Sometimes when mounting use the screws and wall plugs. Lay out the wire in the form of a snake, it is important to make sure that he not fractured, and gradually passed from end to end.
When laying the mats they are fixed to the insulation using double-sided tape. Between the mats are attached using mounting tape. From each grid, you need to retreat at 10 cm and 20 cm On the end mate there is a special clutch. She’s fatter than the rest of the surface, so she need to do deepening.
The most simple styling infrared film. It can be put under any floor covering, no matter where the furniture will stand. That is, the film simply attach the double sided tape and carefully dock it the parts together.
The final stage of operation – screed the floor. Performed by the wet screed, with a height above the cable at least three inches. Under any flooring except tile, suitable for floor screed or self-leveling floor with the same height. Under the tile you need to use a special tile adhesive, which is applied directly to the Mat or tape. On top of it is placed on the tile.
A very important aspect of installation is the fact that the screed or screed needs to harden for about a month. Only then can we lay the final coating.
In some cases, it needs soundproofing. This is necessary if gender is placed under the tile, and under any other cover.
