Liquid-electric warm floor. A combined system of heating X-L PIPE

Heating continues to be the most tangible item of utility costs, so engineers are constantly searching for new cheap sources of heat and as a result, a new unique design and the successful combination of proven technologies. This happened with the innovation of South Korea, which received the name X-L PIPE.

The advantages and problems of conventional technologies

About warm floors (TP) and said a lot today, almost everyone knows what they are species. In this section we will mention the best that give the user the known types of TP. Will also be given to the problem of these systems, which are solved in the technology of X-L PIPE.
The energy intensity of water floor

Water is a great coolant, to improve the quality it added additives, and this product is called “thermal agent”. The mass of the fluid transfers the temperature to all points of the system and saves it for quite a long time.
Problem. Equipment is required for continuous pumping of agent system. Usually it is the boiler that require a separate room and expensive skilled services.
Quick heating and low cost electric floor

The cable warms up much faster than water, because metal is significantly denser liquid. System cost is the lowest (5. e./m2).

Problem. It also cools down much faster — requires frequent re-start to preheat. This increases power consumption and requires a powerful stable mains.
Ease of installation infrared (IR) TP

Simply roll out the tape-pad and connect to the network (socket) via a controller. It can be cover with carpet or laminate, it is allowed for multiple uses. Also acceptable mounting on the ceiling and walls.

Problem. High electricity consumption, comparable to a wired TP. The relatively high cost of the film (about 30. e./m2).

Conclusion — with the obvious advantages of all known types of TP have problems in three areas:

Complicated or costly installation, a lot of equipment.
The high cost of operation (electricity costs).
Rapid loss of temperature.

X-L PIPE — problem solving by combining types

Korean engineers decided to combine literally all known types of TP in a single system, simultaneously getting rid of the disadvantages of each type. As a result, the world saw the sealed system in the form of a plastic pipe (Ø 20-30 mm), filled with a heat capacity agent (liquid), and laid within it heating elements. These elements — anode and cathode — consist of 7 strands of stainless and provide instant heat when energized.

To compensate for fluid expansion when heated, at the end of the pipe is equipped with a compartment filled with soft balls — the voltage at the wall is not transmitted. This increases the service life of the pipe in the system TP to 60 years.

Distinctive features of X-L PIPE:

For heating agent is not required pumping in the system. The boiler, pumps and header are not needed.
The pause time between warmups — 4 hours +23° C (electric TP — 2 hours).
Simple maintenance and repair of the system.
The system does not require calculations, the fit under the furniture, eliminated the problems of incompatibility of equipment, leaks, and poor construction.

Another property that can be attributed to the problem, you can call the obligatory screed 40 mm. In this work, without ties offer only expensive infrared warm floor, the other also require the laying of a layer of mortar.
Installation X-L PIPE with his hands

Installation procedure of this system is 80% similar to laying water TP of flexible tube.

Work order

1. On the base (screed made of foam concrete or PPR) to put heat reflective material — foil substrate.

2.Followed by reinforcing welded wire mesh of 100×100 with a rod 3 mm. If the reinforcement was applied in roughing screed, the mesh is placed just on top of the pipes.

3. On special fasteners (supplied) to lay the pipe “snail” or “zig-zag”. The main requirement is that the pitch pipe 250-300 mm.

Attention! Do not kink, break, cut or other deformation of the pipe.

4. Bring both ends of the pipe to a sealed junction box (supplied in kit). You will need it for service or repair and should be covered with a waterproof tape.

5. Further to the ends of the anode and the cathode is connected to the wire that goes to the regulator and the power source.

6. After installation and testing to install the beacons and lay screed of a special solution to TP or cement slurry with additives.

7. At low temperature, indoor system can be switched on at 15-20° C to accelerate curing of the screed.

Place junction boxes need to be identified in advance so that to access it was necessary to dismantle at least the flooring. You should also provide a convenient location to the regulator, the wire from it will go to the box.

Maintenance of such system shall be performed by specialists because of pumping you need a special pump. The procedure of fixation is reduced to pumping agent, replacement heating filament (it should be easy to preteroti the pipe) and reverse fluid injection. Such prophylaxis is recommended 1 time in 12-15 years, i.e., 4-5 times during the entire period of operation.
