How to combine the pipes of the warm floor with each other: in the screed, if you have been broken or you need to lengthen

Underfloor heating, sometimes referred to as a warm floor system, is a common option for effectively and pleasantly heating your house. Nonetheless, it might eventually need maintenance or modifications, just like any other heating system. Combining the warm floor’s pipes with one another is a frequent task, particularly when handling problems like broken pipes or the need for extensions.

When connecting pipes in a warm floor system, the goal is to create a space where heat is distributed evenly and smoothly. When installing pipes within a screed—a layer of concrete or a comparable substance that gives the floor structural support and thermal mass—this procedure assumes even greater significance.

Preserving the integrity of the warm floor setup is crucial, regardless of whether you’re fixing a burst pipe or expanding the system to encompass a greater region. This entails making certain that all pipe connections are tight and leak-proof and that the overall construction permits effective heat transfer with no weak spots.

It’s important to determine the precise needs of your setup before beginning the process of combining pipes in a warm floor system. Take into account elements like the heating zone layout, the kind of pipes being used (PEX, PVC, or multilayer), and any components that are currently in place but need to be integrated or replaced.

Fortunately, depending on the task at hand and the installer’s or homeowner’s preferences, a variety of methods and techniques exist for combining pipes in a warm floor system. Choosing the appropriate method can help guarantee that your underfloor heating functions well for many years to come, from straightforward repairs to intricate additions.

Which pipes are better to use

For flooring, only shapes that can tolerate high temperatures are appropriate.

There are many different products on the market today that are made of copper, metal-plastic, and stitched polyethylene. We will discuss materials for galvanized pipelines separately.

Every variety has unique qualities and is meant to be used under particular circumstances.

Pipes Reh made of stitched polyethylene

Because stitched polyethylene pipe has excellent operational characteristics and is therefore unquestionably superior to other materials, it is widely used for both cold water supply and warm floor design.

They are made from polyethylene that has a specific density. There are various techniques used to sew products.

The pipeline can belong to various classes depending on the production process:

• PEX-A-in the manufacture, high-density polyethylene is used. The production method is peroxidal, consists in melting polyethylene under the influence of high temperature. After that, the resulting amorphous mixture is squeezed through a special formative hole, this method is called extrusion.

PEX-A is a multi-layer design with an aluminum insert in between the layers to help keep the product’s shape. A specific type of glue is used to join the layers; it is not affected by temperature changes.

Just so you know! The oxygen can be transferred from the product to the coolant. Manufacturers started covering it from the outside with a thin layer of plastic (polyvinyl e) called EVOH to prevent penetration.

• PEX-B-for its manufacture, medium density polyethylene is taken, which is softened to a solid-like consistency. With this method, stitching is carried out after extrusion.
• PEX-C-raw materials in this case, is also polyethylene having an average density. Sewing is carried out at a temperature equal to the environment, while the state of the material is solid.

Stitched polyethylene hoses are commonly utilized for installing heated floors; however, PEX-A is more frequently utilized due to its high elasticity, which enables the installation of highways with bends up to five diameters.

Because PEX-B is thicker, they shatter more readily. Furthermore, because PEX-C cannot withstand high temperatures, it is more frequently utilized with cold water. Products made of this material also weigh less and are sturdy, which is advantageous for manual installation.

PEX-A pipes require heating in order to fully recover their shape after deformation due to their memory. These properties are absent from PEX-B and diminished in PEX-C.

Polyethylene PE-RT

The PE-RT pipeline has been altered; it is not like PEX in that there are no seams. The system composed of these tubes is nearly silent, resistant to below-freezing temperatures but tolerant of above-freezing temperatures, albeit not for very long.

Furthermore, this material has no structural memory and is susceptible to aggressive substances. Nevertheless, because heat-resistant polyethylene is reasonably priced, it is frequently utilized in warm flooring.

Metal -plastic

A great option for a warm floor is metal-plastic pipe. It is plastic and flexible, allowing for bending even in the absence of heat. Furthermore, the material exhibits strength, good temperature tolerance, and environmental friendliness.

The metal-plastic pipeline is made up of multiple layers: the protective polymer coating is located outside and serves as a barrier against mechanical damage, followed by metallized foil inside the stitched polyethylene. In a design like that, neither corrosion nor a scale deposit occur. The pipeline has a 50-year lifespan if installed correctly.

The high heat conductivity of plastic is evident when comparing stitched polyethylene versus metal and plastic for a heated floor. However, there is also a significant chance of curtaining a coil; therefore, this area will need to be removed because such a product is unable to regain its original shape.

Metal

The following types of metal pipes are produced for warm water floors:

1. Copper – have a high cost, so they are not very popular when installing hydropolis. In addition, laying such a pipeline is not easy, special equipment is required, and installation is unlikely to be installed on your own.

But it’s important to remember that copper pipe is a great choice for a heated floor because of these great qualities:

• high thermal conductivity;
• durability;
• non -exposure to corrosion;
• Plasticity and strength.

1. Stainless steel stainless steel is a relatively new species that is well suited for warm floors, but due to the high price they are not often used often. The product has a protective polymer coating, and stainless metal is not subject to corrosion, perfectly tolerates mechanical, chemical and temperature effects.

Furthermore, styling with even the most intricate scheme is feasible with this model, and there is no chance of creases.

In summary, the most widely used models for heated floors are made of plastic pipe or stitched polyethylene circuits.

They are reasonably priced and have good operating characteristics. However, if finances permit, using a copper pipeline—which has excellent heat conductivity and durability—is preferable.

Is it possible to connect the pipes of a warm floor or not?

There are times when laying a pipeline for a heated floor when a solid loop length is insufficient. In this instance, the question of whether and how to combine the pipes among themselves emerges. The method used to join the contours varies depending on the kind of material.

Crucial! Because every connection is meant to support a specific load, the working pressure needs to be considered when selecting a docking technique for the floor pipes.

Let’s take a closer look at the techniques for combining heated floor pipes.

Connection of pipes made of stitched polyethylene and metal -plastic

1. Clubs – such fittings are the easiest when installing at home:
2. A clamping sleeve is put on a polymer hose;
3. The end of the circuit is stretched in diameter using an expander;
4. The pipe is stretched to the stop on the fitting fitting with a stretched edge;
5. The connection place is fixed in this position for several minutes, this is enough for tightly fraining the fitting.

Sewing copper pipes

Copper can be joined with a press or fur-fitting, as well as when installing a plastic circuit. This approach is advised in open spaces so that parts replacement in the event of a leak is simple.

The most dependable and useful method is to solder copper pipes. Although it takes longer to complete, the connection is strong and dependable. Ordering:

• The cuts of the circuit are cleaned outside and from the inside;
• The edges of the parts are lubricated with a special connector for soldering pipes from copper – only from above;
• The products are joined, and the excess mixture is removed;
• The connection place is heated by a gas burner and the solder fills the gaps.

How to combine warm-floor pipes (press fiting)

The pipeline and press fitting can be combined, as was previously mentioned. This particular detail includes:

• Corps – there are different shapes (angle, tee, couplings);
• sleeves – the basis of fitting, stainless steel is raw materials for its manufacture;
• clips – an elastic ring (gasket), which connects the case and sleeve.

Just so you know! To ensure that the pipe is inserted correctly, the fitting case has a "window." You can only move on to the press when the tube is visible through this opening.

A specialized press is used for pressing. Compressing the tool’s handles is the main step in the process. It doesn’t take long to complete, and special skills are not needed to perform this work.

Using this connection also has the advantages of strength, a long service life, and no maintenance required for the design.

Connection of the pipes of the warm floor in the screed

While professionals recommend installing a water-warm floor beneath a screed without connections, making them is not strictly prohibited.

It is important to note, however, that you cannot connect the floor circuits using a threaded method (such as "American" or PH). Connecting the pipes with a press financial or coupling is preferable.

Crucial! Fittings or couplings should be kept separate from the concrete solution when pouring in such areas. You can accomplish this by encasing them in plastic film.

How to solder a warm floor pipe

One popular method for joining warm floor plastic pipes is soldering. The technology is easy to use and doesn’t call for substantial financial outlays. There are two techniques for soldering:

1. Muft – a shaped part is used for this (a coupling or outline with a large diameter). This method is suitable for pipes size 63 mm. The welding process consists in melting the edge of the product from the outside and part of the coupling inside. After that, the details join, forming a dense connection.
2. Straight – consists in smelting small sections of two pipe from plastic, which then join the ends. This simple is a fairly simple way, reliably combines two details into a single contour.

Just so you know! In addition to hot technologies, "cold" soldering is used. The plastic is softened by the use of a unique solvent.

When it comes to connecting pipes for a heated floor, whether you"re repairing a break or extending the system, it"s crucial to do it right to ensure efficient heating throughout your home. First off, make sure you have the right tools and materials handy. Then, carefully plan the layout and measure the lengths needed. When connecting pipes in the screed, ensure they are securely fastened and properly insulated to prevent heat loss. If you"re fixing a break, cut out the damaged section and use couplers to join the pipes securely. For extending the system, use connectors and fittings designed for heated floors to maintain uniform heat distribution. Lastly, test the connections thoroughly before covering them up to avoid any future issues. By following these steps, you can seamlessly combine pipes for your warm floor, ensuring cozy comfort throughout your home.

How to combine a warm floor pipe with a metal -plastic pipe

When installing a warm floor, experts advise using a pipeline made of one material, but occasionally it’s necessary to connect a metal-plastic circuit with goods made of different raw materials.

For instance, when this circuit is connected to heating or water supply components made of steel (copper). A calibrator and a squeezing fitting are required for this task. Thread should be chosen to match the size of a steel pipe, and cuffs and washers should be used on metal-plastic pipelines when joining products made of different materials.

Fitting is wound after packla is wound around a copper pipe. The nut is twisted and the product’s edge is getting closer to the cone.

In the event that polyethylene products are required to dock the metal-plastic circuit, threaded fittings specifically designed for this purpose can be employed as a connector for the pipes beneath. This type of joint is typically installed when a heated floor is connected to a boiler.

To keep your house cozy and energy-efficient, you need to make sure your warm floor system is working properly. Appropriate techniques are essential when connecting pipes in the warm floor system, whether they are in the screed, repairing a broken segment, or expanding the system.

One way to connect pipes in the warm floor system is to use fittings made just for this kind of connection. By enabling a safe and leak-proof connection between pipes, these fittings guarantee the system’s continuous flow of heated water. It’s critical to use fittings compatible with the piping type used in your warm floor system when connecting pipes in the screed.

It is imperative that you take immediate action to prevent additional damage and preserve the efficiency of your warm floor system in the event that you discover a broken pipe. Depending on how bad the damage is, you might have to cut out the broken pipe section and install a new one. To keep the system functional and uniform, make sure the replacement pipe is the same size and type as the current piping.

Meticulous planning and execution are essential for expanding your warm floor system. Start by planning the extension’s layout and measurements, keeping in mind things like the size of the room and the need for heating. Connecting the new pipes to the existing system can be done once you have a clear plan in place.

To get the most out of your heated floor system, the pipes must be properly insulated. By insulating the pipes, you can reduce heat loss and make sure that the heated water gets where it’s going without using a lot of energy. For best results, use premium insulation materials and adhere to recommended installation procedures.

In conclusion, proper technique and close attention to detail are necessary when connecting pipes in a warm floor system.
