Which pipe is better suited for the installation of the heating system of the house - a review of all options

a photo As a rule, if there is a choice among the same type of goods, we first pay attention to the numbers that appear in the price list.When it comes to the purchase of pipes for the heating circuit installation, the cost of products "plastic" is about the same.But are they all equal in their characteristics, and there is absolutely no difference what mount?And maybe, "metal" will be more reliable, especially since we are accustomed to it from childhood?Let's face it.

Probably, before making a definite choice, you need to clearly understand what difficulties and nuances have in the course of all events encountered.For manufacturers, advertising their products cause so much their advantages over similar products that immediately there is a desire to buy.But the question is - and whether all these advantages pipe so important, and what better to opt for a closed heating system type?

begin with an assessment of all the nuances of its installation and operation.

features of autonomous systems

What is the difference between them and the central heating mains?

First , no strong pressure surges as work pressure testing "private traders" spend only in exceptional cases.Generally, "jumps" may be, but is small in the case of "airing" of the system when the safety valves malfunction.

Secondly , operating pressure in closed circuits rarely exceeds 2.5 atm, while in the "high-rise buildings," and can reach 10.

Third , no coolant in aggressive substances, which are introduced inhis stage water treatment with centralized heating.

On this basis, it is clear that issues such as the inertia in relation to various himsoedineniyam and the ability to "hold" high pressure pipe autonomous circuits are not relevant.

Opportunities host

If there is money, but there is no desire to deal with the installation of pipes, the difference in principle or not.Salaried workers will pick up the necessary material.However, in practice autonomous heating systems in private homes owners prefer to equip their own.So, we need to consider:

  • metal-plastic - pipe personal abilities, skills;
  • free time;
  • provide the necessary tools and accessories;
  • knowledge of all the features of heating systems - what are the wiring scheme how to install shut-off valves, dock the individual elements and then some.

From this perspective, the material should be easily processed, connected, bend and so on.




Fitting

  • Where is the part of the route - inside the house or outside?So - temperature conditions of use.
  • What gasket planned - openly or covertly?Consequently, as the track would "look" at the background of walls.
  • as fixed on the basis of?This largely depends on the material and surface weight tubes.

This is now quite consciously, you can see all kinds of pipes for heating system installation, note the features and evaluate the feasibility of using.

Metal

Such pipes are durable and able to withstand high temperatures.But it is necessary to consider that their is quite difficult to bend (you will need a bender), have threaded and securely seal the joints.

Copper

«Pros»

  • honey metal is relatively soft and therefore easy to process;
  • can be installed without the "disguise", since the appearance of the pipe is quite attractive;
  • is believed that copper is "clean" heat transfer medium, so salt deposits - minimum;
  • lightweight, so there will be difficulties in mounting;
  • do not need to be painted;
  • period - about 100 years.

«Cons»

  • high price;
  • restriction in the use of heaters.For example, aluminum radiators (the cheapest) in such a system can not be installed;
  • particular installation, which are known only to professionals.For example, how to articulate correctly the pipe copper and steel (or plastic)?Nuances are more than enough.

«Galvanizing»

metal - tube «Pros»

  • given coating material, these pipes do not rust, therefore they often do not have to paint (if it is provided on-site).

«Cons»

  • steel is expensive;
  • some limitations in the application.A large number of joints (for example, with "radiation" layout) entail additional risks for the appearance of leaks.

«Stainless steel» Corrugated

It is rarely used, despite the ease of installation.To crimp fittings necessary special devices which are expensive and there is virtually only among professionals.

Metal Black

«Pros»

  • perhaps the only - low cost in comparison with analogues.

«Cons»

  • roughness of the cavity, which causes an intense accumulation of salts;
  • susceptibility to corrosion.As a consequence - rust coolant particles that clog filters, not only, but also boiler heat exchanger;
  • need for periodic "tint".

Plastic pipes

They do not rust, salt deposits on the walls due to the ideal smooth surface virtually none.Easily handled, and do not need to cut the threads for the connection.However, these pipes are subject to deformation and "afraid" of ultraviolet light.

Polypropylene

PPN «Pros»

  • easy installation;
  • easy to "dock" with elements of other materials;
  • the cheapest option;
  • easily and securely connected (on their welding here);
  • low cost.

«Cons»

  • little bent, so all the connections - only by means of fittings;
  • fear of external thermal effects (melted material);
  • may damage the circuit when the coolant temperature increase of more than 95 0C.

Council - preferably use products with reinforcement.In this case, dramatically decreases the thermal expansion of the material and increases its strength.

advisable to use in circuits, which are characterized by high water temperature.

Polyethylene "crosslinked»

to him in full measure everything mentioned above - for polypropylene (except for the temperature dependence).But there is another, and very significant, shortcoming.In the process of installation is necessary to use special equipment, which is quite expensive, and acquire them "at once" makes no sense.It is therefore hardly suitable for self piping runs of cross-linked polyethylene.Without the help of professionals will not work with them.

At the same time, such products are considered an excellent option for underfloor heating.It is only necessary to mount the "one-piece" a piece without joints.

layer

Metal-

«Pros»

  • good combination of strength and "elasticity".These tubes can be bent, which is especially handy when laying tracks in areas with a complex configuration;
  • withstand low temperatures, and therefore can be used for laying on the territory;
  • easily connected by press-fitting.

«Negative»

  • He rather relative - need inexpensive device for crimp fittings.

Conclusion

install metal pipe in a private home it is advisable only in certain sections of the route, which are not available for visual inspection.

And then, only in certain cases:

  • if the owner assumes check tightness of connections overpressure;
  • when repair is quite difficult to produce (for example, the "warm floor");
  • when the probability of excessive mechanical action on the "thread".

The best option - pipes made of copper, given the duration of their trouble-free operation.But when you consider what it would cost this installation, it becomes clear that for the vast majority of owners is unacceptable.

Whoever wants to save as much as possible, it is advisable to mount Polypropylene products.And for those who are concerned, above all, the durability at a low cost, we can recommend a pipe made of metal.

The article deals with all kinds of pipes and provides some guidance.And what exactly to choose for your home, the reader will now be able to solve itself.
