Installation of heating in a private house with your own hands. Do-it-yourself heating from polypropylene pipes

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

Advantages of the polypropylene heating system

This heating scheme is characterized by a lot of advantages, among which it is worth highlighting the following:

• Ease of installation - such a system is quite easy to perform on its own, in addition, work is done in a short time.
  
• Reliability and durability - polypropylene is considered to be a modern material, its service life is more than 50 years, it is not prone to the formation of scale, corrosion and other deposits, it tolerates chemical and thermal effects. Due to the high-quality connection of pipelines, their leakage is completely eliminated.
• Low cost - in comparison with heating systems from cast-iron, steel or metal-plastic pipelines, installed heating from polypropylene pipes with your own hands in a private house will be several times cheaper.
• Environmental friendliness.
• Efficiency - polypropylene pipes have excellent heat-insulating characteristics, which significantly reduces heat loss and, accordingly, ensures uniform heating of heating devices and generally increases the efficiency of the system.
• Quiet operation - polypropylene pipes also have good soundproofing qualities.
• It is possible to improve the aesthetic appearance of the room - due to durability and high reliability, the installation of heating in a private house with your own hands can be done inside building structures.
• The quality of installation work depends on the material chosen: it is advisable to use reinforced pipes for heating systems, ordinary products are suitable for water supply and sewage.
• Polypropylene pipes 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 low-quality raw materials, as well as violations of production technology.

Polypropylene pipes for heating, types and DIY installation

Currently, the construction market offers a huge selection of polypropylene products. However, before you purchase them, you must 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. For the manufacture of such pipes, thin-walled polypropylene (1.9-10 mm thick) is used, which is designed for a temperature in the system of up to 20 ° C and a working pressure of no higher 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, in connection with this they are almost never used.

Pipes PN-20

These products have an internal diameter of 10.6-73.2 mm, an external diameter of 16-110 mm, wall thickness can be 1.6-18.4 mm. These pipes are designed for temperatures up to 80 ° C and operating pressure no higher than 2 MPa. This category of pipelines is universal. However, in the heating system they can be used exclusively in the return pipe, and the water temperature should not be higher than that indicated above.

Pipes PN-25

This is the best option in order to make the installation of heating in a private house with your own hands. The main distinguishing feature of these products is their multilayer execution (two layers of plastic, between
which lay the layer of aluminum treated with glue). An aluminum product has an external diameter of 21.2-77.9 mm and an internal diameter of 13.5-50 mm. Such polypropylene operates in a heating system with a working pressure of no higher than 2.5 MPa and a temperature of up to 90 ° C.

The presence of an aluminum layer reduces the coefficient of expansion of pipelines during the passage of coolant through them. However, when choosing reinforced products, its location must be taken into account. If the interlayer is placed closer to the outside, this will complicate the soldering process, in this regard, the installation of heating in a private house with your own hands in this case will require the purchase of additional equipment (a special trimmer or shaver).

Another variant is pipelines reinforced with fiberglass; they are similar in quality to products with a layer of foil in terms of quality. However, the first type is characterized by a high rate of thermal expansion, but their installation is a little easier.

Pipe connection

Two main technologies are used to connect pipelines (diameter up to 63 mm):

1. Bell-shaped spike - one end of the coupling is inserted into the other, expanded specifically for this.
2. Socket welding - both ends are included in a special part (socket).

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

For connecting pipelines (diameter over 63 mm) butt welding technology is used. In this case, the installation of couplings is not required, since this connection has high reliability. With the right fittings, you can use welding couplings.

Design of heating systems

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

If the installation of heating is carried out in a country house, then the boiler should be installed in a separate room. The apartment may 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 consider that the return pipe should not be lower than the feed to the boiler, otherwise the circulation will be somewhat difficult or completely impossible. To do this, you need to draw up a three-dimensional diagram of the pipelines indicating the heating devices, the levels of passage of the enclosing structures and the angles of rotation.

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

Types of installation

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

1. The upper spill is a gravity type that is caused by temperature differences. 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. Bottom spill - the movement of the coolant along the heating circuit is forcibly carried out by means of a pump. The main advantage of such a system is the possibility of its use in multi-story buildings. In addition, small pipelines can be used, with this wiring configuration this does not matter.

Tools and equipment required for installation

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

• Pipes made of polypropylene with various diameters (for connecting to heating devices and the main circuit).
• Scissors for polypropylene.
• Electric soldering iron with a set of nozzles.
• A perforator may be required for wall chipping.
• Marker.
• Roulette.
• Wall mounts (plastic clips or metal brackets).
• Couplings, corners, adapters.

Do-it-yourself heating in a private house: schemes, calculation and installation

The main point when installing a system of polypropylene pipes, on which it is necessary to concentrate special attention, is the connection of structural elements (pipes, fittings). For this, a special welding machine should be used.

To install the heating system from polypropylene, you must:

1. First of all, you should draw a layout of pipelines.
2. Then the meter is calculated polypropylene pipes. The calculation is carried out according to the scheme specified 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. Next, before you install the heating of a private house with your own hands (the scheme should be drawn up in advance), you need to purchase all the material and let it settle for about a day at room temperature. This is required so that during installation and subsequent operation on the plastic, cracks do not appear as a result of sudden temperature changes.
6. On pipelines are outlined cutting sites.
7. Sections are made on the lines marked with a marker using special scissors.
8. The soldering apparatus is placed on a horizontal surface, a non-fat nozzle is installed, equal to the diameter of the pipeline.
9. The soldering tool heats up to 260 ° C.
10. Fittings and pipes are placed in the hole of the heating element. Then they are heated.
11. Parts are removed and the pipe is inserted into the fitting. It is important that these parts are not cold during the connection.

When water heating is in a private house, the circuit and do-it-yourself installation are fully completed, before you start the system fully, you must first test it. Pipelines for some time (at least two hours) are filled with water to detect problems and resolve them in a timely manner.

Installation Rules

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

1. For cutting pipes into individual workpieces, it is recommended to use
   special scissors, equipment or a sharp knife. It is important to observe an angle of 90 °.
2. 
   Additional installation of holders will help to increase the reliability of fastening of pipelines, as well as prevent their possible sagging.
3. Before proceeding with the installation process, it is necessary to check all products for any contamination on the inner walls.
4. The most optimal temperature indicator in the room when installing the heating system is +5 ° C.
5. For polypropylene pipelines, protection against the effects of high temperature and mechanical factors should be carried out.
6. Reliability and quality of fittings fasteners can be improved if you use FUM tape during installation.
7. Before using the welding machine, it should be heated to the required temperature.

Useful 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 pipelines made of polyethylene is allowed only 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, remove all existing dirt from the edges of the pipe. This can be done with a dry, clean cloth. After that, the surface is rubbed 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 directory, depending on the diameter of the purchased products.
