Designing a heating system in a private house is one of the most important stages of future comfortable living. The choice of a gas boiler, heating radiators is important, but for the high-quality functioning of the entire heating system it is necessary to select the “right” pipes. Pipes for heating a private house, what is better, what material they should be made of - you will find the answers to these questions in this article.
- Which pipes are better for heating?
- The best choice of pipe choice for heating your
domestic heating network. Independent heating is, first of all, convenience. You will be able to provide your house with heat at any time of the year, install the desired number of radiators, and also save substantial funds.
The performance of your home heating network will depend on the performance of the pipes and their proper installation. They must be heat-resistant, wear-resistant, in the case of a defect it is easy to replace with similar fragments( the possibility of replacing individual sections).When selecting these structural elements, it is necessary to consider how they will be installed( in an open or hidden way).
Which pipes for heating are better?
This question has become relevant relatively recently, because earlier steel pipes were the only choice in the arrangement of the heating system. Despite the fact that the construction market today has many improved analogues, they also should not be written off. Steel structural elements will be the best choice, if a gravitational heating system is planned in your house, installation of large diameter pipes is required. They are durable, resistant to mechanical damage, able to withstand very high temperatures, allow you to maintain high pressure at a constant level.
The assembly of steel fragments is done by welding. Due to exposure to corrosive processes, this type of pipes is not recommended to be used as a latent heat system( placement inside walls).The so-called minus is an unaesthetic appearance and the need for painting, because due to high temperatures the paint periodically peels off from the surface, exfoliates, turns yellow with time. Steel pipes are distinguished by a long operational life( more than 50 years), have a relatively low price.

Another budget option is plastic pipes for heating, also called polypropylene pipes. They are quite popular, differ in technical characteristics, structure. Analogs from European manufacturers, such as Sanext or Aquatherm, are quite suitable for the requirements of the domestic heating system, they are light, easy to install, and are not subject to corrosion processes. It should be borne in mind that pipes without a protective coating inside have limitations with respect to the heating temperature - if the threshold is exceeded, ruptures and deformation are possible. Plastic fragments are joined by special soldering, in the joints corresponding couplings and adapters are installed.
Polypropylene pipes for heating have a smooth surface, on which limescale does not collect, rust does not appear. They are distinguished by a long operational period( more than 20 years), are not afraid of freezing, do not require painting, have a neat appearance, practically do not change color over time. Pipes made of this material do not bend, but with the help of adapters and fittings you can install even the most intricate configuration. As mentioned above, these plastic structural elements are characterized by lower heat resistance, their working temperature is only 70 degrees, with a 90 degree indicator there is a risk of material deformation.

In this case, the analog of cross-linked polyethylene( PEX) is much more practical, it perfectly withstands high temperatures and can be safely used to install an autonomous heating system. Such pipes can be heated and give them the desired shape( memory effect), they are durable( more than 50 years), have all the positive qualities of their plastic "brothers".They are not afraid of corrosion, they can also be installed inside the walls.

The best choice of pipes for heating your home heating network
If we consider plastic pipes for heating, which one is better to choose? Metal-plastic structural elements are considered the most popular for home heating systems; they brilliantly combine the best qualities of steel and polypropylene analogues. In a section before you the multilayered structure from plastic and aluminum appears. The aluminum layer provides protection and safe operation at high temperatures, and plastic protects aluminum from corrosion processes. Installation is simple - special crimp fittings or press fittings without the involvement of specialized equipment. This option is durable in use( 50 years), but it should be borne in mind that freezing water is detrimental to metal pipes( fraught with gaps).That is, for arranging the heating system of a country house, where the owners come periodically, they will not work.
The best, but the most expensive option for a home heating system is copper pipes. Special equipment is used for their installation. Copper pipes for heating and fittings to them have a high cost. In this case, high-quality connecting elements( capillary fittings) are very important, since the use of budget options dramatically increases the risk of depressurization of the heating system. Personally, the installation of the system does not overpower, because when docking the copper fragments a special type of soldering with solder containing silver is used.
These structural elements can withstand temperatures up to 500 degrees, their service life is more than 100 years, they are not afraid of frost, corrosion, look very aesthetically pleasing. In terms of high technical and operational indicators, copper analogues can be considered an almost ideal option for arranging a heating system in a private house. They can also be used for installation in a hidden way and for a floor heating system.

A convenient, practical option for arranging an autonomous heating network is glass fiber reinforced polypropylene pipes for heating. These are the best representatives of a class of plastic and polypropylene pipes. They differ from their more simplified counterparts in that they have a rigid framework inside that prevents expansion, which can occur under the influence of high temperatures. Such structural elements can be laid without fear inside the walls, even if swelling occurs at a certain section, this will not affect the operation of the system as a whole. The fragments are fastened using special welding or a threaded joint.
Summing up and answering the main question: which pipes for heating are better for a private house, I would like to advise you not to resort to excessive savings. In this question we are talking about your home, comfort and health of loved ones, so everything must be done with high quality and for a long time. The heating system made of copper will be the ideal choice, but here the question of material costs is at the head of the decision. The heating system made of glass fiber reinforced polypropylene is also quite reliable, and is also a good and durable option.
Pipes for heating a private house, which is better to choose? The old truth says - the good does not happen cheap, but from myself I also want to add: to acquire the most expensive is not always appropriate. Thoroughly examine all the nuances, calculate all the options, choose a solid, proven building material that suits your requirements.
