In modern construction, laminate flooring has gained great popularity. Laminate has the appearance of wood but is several times cheaper than it. In addition, due to sufficient thermal conductivity, it is ideal for creating a “warm floor” heating system. The warmth emanating from the floor creates comfort in the house, even in the coldest weather. What is a warm floor under a laminate on a wooden floor and is it suitable or not? These questions are asked by everyone who has decided to arrange this system at home.
What is underfloor heating under a laminate on a wooden floor or on a concrete base?
Today there are 3 types of underfloor heating. They are all based on completely different principles:
- Water system.
- Electrical cable.
- Infrared electric.
The main feature of this system is that the heat sources are located under the surface of the floor covering. The heat generated by them warms the coating, which transfers energy to the surrounding air. For each species, any of the following is true:
- heat is distributed evenly;
- the system is very efficient;
- lack of heating elements in prominent places;
- dust does not circulate through the room, as is the case with radiator heating.
Any of them can be mounted on a concrete base or on a wooden floor. Underfloor heating under the laminate of each of the listed types has its own advantages and disadvantages.
Helpful advice! In order for the water floor to function more efficiently, it is necessary to create not one circuit, but 6 or even 8. This will allow for a more even distribution of heat. The tubes will be shorter, so the heat loss will be reduced.
Installation of a water floor heating on a wooden floor is absolutely safe
The heat source for such a device is heated water circulating through tubes that are located directly under the laminate. Modern industry produces tubular products for these purposes, made from the latest materials using innovative technologies. Thanks to this, polyethylene and metal-plastic pipes ensure the complete safety of the system. Any water leaks are excluded.
To lay a water-heated floor, it is necessary to lay a damper tape around the perimeter of the room. Then, on top of the rough base, arrange hydro and thermal insulation, lay out the reinforcing mesh. Then the pipes are laid in a parallel or spiral manner. In the first case, the drawing looks like a snake, and in the second, like a spiral. The ends of the pipe are closed to the heating circuit, so that water circulates freely inside.
The next stage is filling the entire structure with a sand-cement mixture. The resulting screed is leveled for laying the laminate. In the process of circulation of the coolant through the pipes, the cement will warm up, evenly transferring heat to the laminate.
This type of underfloor heating has a number of advantages:
- safe operation;
- reliable functioning;
- no electricity supply is needed if the circulation of the coolant occurs naturally.
It also has some drawbacks:
- complex installation;
- the height of the ceilings decreases due to the device of the concrete screed;
- if the pipe is damaged, it will be quite difficult to repair the system.
Such a system is absolutely safe for installation on a wooden floor. The warm floor under the laminate, arranged in this way, will last a long time.
Electric type underfloor heating device
The principle of operation of the system is based on the property of conductors to heat up when an electric current passes through them. The heating element is a special self-regulating electric cable. It is able to automatically change the resistance in those areas where overheating is detected. This is necessary to avoid burnout. The cable is available in single-core and two-core.
Before starting the installation, the surface is leveled and a thin sand-cement screed up to 0.3 cm thick is made. If necessary, heat insulation is arranged under it. Drying will take place after 3 days. Only then can the mounting tape be attached. Then you need to fix the thermostat in a convenient place and lay the cable according to the instructions on the package.
At the end of the installation, the screed is again made from 3 to 10 cm thick. It will reach complete drying only after a month. Only then can the flooring be laid. The German-made 33 class 12 mm thick waterproof laminate is very suitable for this.
- operational reliability;
- long, more than 20 years service life;
- easy installation and maintenance;
- electronic control of the optimum temperature.
Among the shortcomings, it is necessary to indicate the following:
- the presence of, albeit weak, but electromagnetic radiation;
- high cost of electricity.
Made in Germany, the 33 class 12mm waterproof laminate is perfectly matched to the electric type of floor heating.
Helpful advice! For a warm floor at home, it is better to buy a two-core cable. It is much easier to stack it.
The peculiarity of using an electric type of warm floor is to select the optimal mode, which provides sufficient heating with optimal use of electricity.
Infrared film warm floor
This is the most innovative floor heating system. It is a film that, as a result of exposure to an electric current, is capable of emitting the infrared range of electromagnetic waves. This range of the spectrum is invisible to the human eye, but it is felt by the skin as warm. Half of the sun’s energy is infrared rays. The absence of glowing elements is the main feature of this material.
In the installation, such a system is the most convenient. It is enough to lay a heat-reflecting coating on a leveled base, and already on it an infrared film. The topcoat, which can be a German-made 33 class 12 mm thick waterproof laminate, is laid directly on the film itself. There is no need to screed, which is a lengthy and time-consuming process.
Helpful advice! It is better to put a substrate under the laminate not made of foamed polyethylene, as is most often done in normal conditions, but duplex or isoplate. These materials are waterproof.
Advantages of the infrared film:
- very reliable and durable system;
- installation of such a system is the easiest of all types of underfloor heating;
- the absence of incandescent elements reduces energy consumption very significantly.
The disadvantages are:
- too high a price;
- fear of moisture;
- risk of damage during installation.
The peculiarity of the operation of such a floor is extreme caution. He is afraid of rough mechanical stress. Therefore, do not put heavy furniture on such a surface. This can damage the film and render it unusable. It is better to use such a system in open spaces.
Each owner independently chooses the type of underfloor heating for the device at home. The decision is made depending on preferences and the availability of financial capabilities.
