Installation of heating in a private house with their own hands. Heating of polypropylene pipes by hands

To increase the efficiency and improve the operating life of the heating system, professionals recommend that the installation of heating in a private house with their own hands using pipes made of polypropylene. Already after a year of operation, the efficiency of their analogues from metal decreases, all because at elevated temperatures these pipes begin to rust from the inside.

Advantages of the heating system from polypropylene

For this scheme of heating, there are many advantages, among which there are the following:

• Ease of installation - such a system is fairly easy to perform on its own, besides the work is done in a short time.
• Reliability and durability - polypropylene is considered a modern material, its operational life is more than 50 years, it is not susceptible to scale formation, corrosion and other deposits, it tolerates chemical and thermal impacts. Due to the qualitative connection of the pipelines, their leakage is completely excluded.
• Small cost - in comparison with heating systems from cast-iron, steel or metal-plastic pipelines, the mounted heating from polypropylene pipes by own hands in the private house will be several times cheaper.
• Ecological compatibility.
• Efficiency - pipes made of polypropylene have excellent thermal insulation characteristics, which significantly reduces heat losses and, accordingly, ensures a uniform heating of the heating devices and, on the whole, increases the efficiency of the system.
• Noiselessness of work - polypropylene pipes also have good soundproofing qualities.
• It is possible to improve the aesthetic appearance of the premises - in view of the durability and high reliability, the installation of heating in a private house with their own hands can be done inside the building structures.
• The quality of the installation work depends on the material selected: for heating systems, it is advisable to use reinforced pipes, for the water supply and canalization, conventional products are suitable.
• Pipes made of polypropylene are sensitive to high temperatures, so they are not recommended for use in fire-hazardous areas.

Disadvantages of polypropylene products

It is very important to buy polypropylene pipes only from trusted manufacturers, since their shortcomings directly depend on the use of poor quality raw materials, as well as violations of production technology.

Polypropylene pipes for heating, types and installation by own hands

Currently, the construction market offers a huge selection of polypropylene products. However, before you buy them, you need to understand their properties and markings.

Pipes PN-10

These products have an outer diameter of 20-110 mm, an inner diameter of 16.2-90 mm. To make such pipes, thin-walled polypropylene (1.9-10 mm thick) is used, which is designed for a system temperature of up to 20 ° C and a working pressure of not more than 1 MPa, so it is not used in heating systems.

Pipes PN-16

Their use is allowed at temperatures up to 80 ° C, but this type of pipe is very rare, so they are almost not used.

Pipes PN-20

These products have an internal diameter of 10.6-73.2 mm, an outer diameter of 16-110 mm, a wall thickness of 1.6-18.4 mm. These pipes are designed for temperatures up to 80 ° C and operating pressures not exceeding 2 MPa. This category of pipelines is universal. However, in the heating system, they can only be used in the return pipeline, and the water temperature should not be higher than that indicated earlier.

Pipes PN-25

This is the most optimal option for making the installation of heating in a private house with your own hands. The main distinguishing feature of these products is their multilayered performance (two layers of plastic, between
Which is laid layer of aluminum, treated with glue). The aluminum product has an outer diameter of 21.2-77.9 mm and an inner diameter of 13.5-50 mm. Such polypropylene functions in the heating system with an operating pressure of no higher than 2.5 MPa and a temperature of up to 90 ° C.

The presence of an aluminum interlayer reduces the coefficient of expansion of pipelines as the coolant passes through them. However, when choosing reinforced products it is necessary to take into account its location. If the interlayer is located closer to the outside, this will complicate the process of adhesion, in this connection, the installation of heating in a private house with their own hands in this case will require the purchase of additional equipment (a special face or a shuiver).

Another type is fiberglass-reinforced pipelines, they are similar in quality to products with a layer of foil. However, the first type is characterized by a high index of thermal expansion, but their installation is slightly simpler.

Piping connection

For connection of pipelines (diameter up to 63 mm) two main technologies are used:

1. Spigot joint - one end of the coupling is inserted into the other, expanded specially for this purpose.
2. Coupling welding - a special part (coupling) includes both ends.

A threaded connection can also be used , fittings with a bell are used for its implementation.

To connect pipelines (diameter more than 63 mm), butt welding technology is used. In this case, the installation of couplings is not required, since this connection has high reliability. If there are suitable fittings, you can use welding couplings.

Designing of heating systems

Before heating in a private house with their own hands, it is necessary to design it correctly.

If the heating is installed in a country house, the boiler should be installed in a separate room. The apartment can be placed in the kitchen or in the hallway. The room must be equipped with an exhaust system.

When planning a heating system, it is important to take into account that the return pipeline must not be lower than the supply to the boiler, otherwise the circulation will be somewhat difficult or absolutely impossible. To do this, a three-dimensional diagram of the pipelines must be drawn up, indicating the heating devices, the levels of passage of the enclosing structures and the corners of the turns.

It is worth noting that it is much easier to make heating from polypropylene pipes by hand in a private house than any other system. The plan calculates the length of the pipeline, the number of connecting and turning parts.

Types of installation

Installation of the system from polypropylene products can be carried out in two types:

1. The upper spill is a gravity type, which is caused by the difference in temperature. Such a system in private homes is the most common, as it is simple, reliable and does not require the installation of expensive pumping equipment.
2. Lower spill - the movement of the coolant through the heating circuit is forced by means of a pump. The main advantage of such a system is the possibility of its use in multi-storey buildings. In addition, small diameter pipelines can be used, with this wiring configuration it does not matter.

Tools and equipment required for installation

To conduct the heating of a private house with your own hands (the scheme of the system must be drawn up in advance), the following will be required:

• Pipes of polypropylene with different diameters (for connection to heating devices and main circuit).
• Scissors for polypropylene.
• Soldering iron with a set of attachments.
• You may need a perforator for strobing the walls.
• Marker.
• Roulette.
• Wall mounts (plastic clips or metal brackets).
• Couplings, corners, adapters.

Heating in a private house with their own hands: schemes, calculation and installation

The main thing when assembling a system of polypropylene pipes, on which it is necessary to concentrate special attention, are the connections of structural elements (pipes, fittings). For this, a special welding machine must be used.

To install a heating system made of polypropylene, you must:

1. First, draw a diagram of the location of the pipelines.
2. Then the polypropylene pipes are calculated. The calculation is carried out according to the scheme indicated in the previous paragraph.
3. The length of the pipelines in each individual section is calculated.
4. Fittings of the required size are selected.
5. Further, before installing the heating of a private house with your own hands (the scheme must be prepared in advance), you need to purchase all the material and allow it to lie down for about a day at room temperature. This is required to ensure that during the installation and subsequent operation on the plastic there are no cracks due to sudden temperature changes.
6. On the pipelines, the marks of the cutting places are made.
7. On the lines marked by the marker cuts are made by means of special scissors.
8. The soldering device is placed on a horizontal surface, a degreased nozzle is installed, equal to the diameter of the pipeline.
9. The soldering tool is heated to 260 ° C.
10. Fittings and pipes are placed in the hole of the heating element. After that they are heated.
11. The parts are removed and the pipe is inserted into the fitting. It is important that these parts are not cold during the connection process.

When the water heating is in a private house, the circuit and the installation by one's own hands are completely fulfilled, before the system is fully launched, it is necessary to test it beforehand. Pipelines for some time (at least two hours) are filled with water to detect malfunctions and timely eliminate them.

Mounting rules

Each person, performing the heating of a private wooden country house with his own hands, must adhere to the following rules:

1. For cutting pipes into individual blanks, it is recommended to use
   Special scissors, equipment or sharp knife. It is important to observe the angle of 90 °.
2. Additional installation of the holders will help to increase the reliability of the piping fastening, and also to prevent their possible sagging.
3. Before proceeding with the installation process, it is necessary to check all the products for any impurities on the internal walls.
4. The most optimal temperature in the room when installing the heating system is +5 ° C.
5. For pipelines made of polypropylene, protection from high temperatures and mechanical factors must be ensured.
6. The reliability and quality of the fitting of the fittings can be increased if used in the installation of a FSM tape.
7. Before using the welding machine, it should be heated to the required temperature.

Helpful Tips

To know how to properly install the heating of a private house with your own hands from A to Z, it is advisable to familiarize yourself with the following recommendations:

1. Soldering of polyethylene pipes may only be carried out if the room temperature is at least +5 ° C. Otherwise it will be completely impossible to achieve an ideal connection, and as a result, the heating system will fail too quickly.
2. Before soldering, it is necessary to remove all the existing dirt from the edges of the pipe. This can be done with a dry clean rag. After that, the surface is wiped off with alcohol, which is diluted with water in a ratio of 1: 1.
3. The time of welding and cooling of pipelines is determined by a special reference book, depending on the diameter of the purchased products.
