Pipes for heating - which is better to choose for the construction of a reliable system?

what is required of a person at all times to your home?Of course, the warmth and comfort - the main aspects of the issue.To argue with this opinion is meaningless because no arguments can not prove otherwise.High levels of these characteristics can provide efficient heating system.Yes, it is effective, why wasted on substandard equipment, devices and materials.We live in a new century, and it makes its own rules and laws, and a person must meet them.For the full functioning of the coolant needed to heat the pipe: what to choose, if today the range of diverse and multi-faceted?Try to understand.


Basic requirements for heating pipes ↑

Undoubtedly, in the whole system of heating pipes play an important role.It can be said that their function is very responsible, because it is delivered to the hot water pipe from the boiler (regardless of its kind) to the radiators.Based on this argument, you can define the primary requirements for the pipes they must be durable and maintain this characteristic over the entire lifetime.And for long service pipe must not let oxygen as this contributes to rust from the inside of the system and the pipe clogged and "overrun."This reduces the productivity of the whole system.

«Black" metal device heating circuit is rarely used, it quickly rust, maintenance free

From the tightness of the system depends on maintaining the optimum temperature, and the person must be confident in the reliability of the pipe, that the coolant does notIt goes beyond the contour of the pipe and not spoil the materials and equipment, which is nearby.Strength properties are largely determined by the material of construction of one or the other tube.The modern market offers a lot of options, but you need to soberly assess the situation and consider all the details, so as not to be in a force majeure situation, especially in the winter.After failures in the heating system during the cold season are not wanted and unwanted.

Low Noise - factor is not less important.Calm and cozy atmosphere in the house is broken wildness constant current of water.And yet, a beautiful aesthetic pipe also has not been canceled.It is not always possible to hide the wiring in the walls, for example, if the house is wooden.But in other cases, where some of the pipe all the way out to the surface and connected to the radiators.

pipes heating circuit must necessarily conform to the above requirements in each case, since the choice of pipe also depends on some indicators about them and now it will go.

What influences the choice of pipes ↑

When choosing pipes for heating is necessary to pay attention to the following points:

  • type gasket - outer or hidden;
  • average coolant temperature and pressure in the heating system;
  • installation - difficult or easy configuration of the system;
  • location of the pipeline - in the case of the pipeline will take place on the premises, which is not heated, then you need to consider options for insulation;
  • analyzing, if necessary, repair of pipes and, more importantly, good access to them.

The thing is that the pipes are made of different materials, and thus have a particular gasket installation, assembly systems and performance.

dependence on heating systems ↑

Probably everyone knows that there are two very basic heating system: centralized and individual.Naturally, the tube must meet particular system, such as in private homes and cottages system equipped on an individual basis: pressure in the pipes in this case not more than 2-3 atmospheres.

A central heating system, which is used in urban high-rise buildings, perhaps 16 bar pressure.Basically, these high rates are achieved during system startup to clean the pipeline from slugging.

Central heating
Pipes for central heating

must now consider in detail the possibility of using different types of pipes in these heating systems.Basically, there are four types of pipes:

  • reinforced - suitable for both heating systems because they are designed to pressure 25 atmospheres;
Reinforced pipes
Universal reinforced pipes are durable, and the ability to withstand the critical values ​​of pressure crimping seasonal
  • polypropylene pipes are best suited for an individual system, as they are only designed for 6-10 atmospheres;
  • metallooplastikovye pipes are used in the individual and in the central system.They are durable and resistant to corrosion;
  • steel pipe is more common in centralized heating systems.But if there is a weld joint, not threaded, the pipes are more exposed to corrosion and a protective layer of the pipe collapses.

If we talk about the system with natural circulation and floor boilers, it is difficult to do without the metal pipes.Value / diameter in this case will be the best, because the cost of 1.5 inch copper or multilayer tubes and the like from the "black" were different at times.

Generally in plumbing "black" metal pipe rust quickly, but the central heating system is not the case.The water that is heat medium circulates in a pipe for a long time, oxygen evaporates rapidly and the system is made of steel pipes, is 50 years.

Pipes for auxiliary heating
device for heating systems is preferably selected metal and plastic pipes and plastic

When using the wall of the boiler with a copper heat exchanger in conjunction with forced circulation, ie pump, steel pipes will only interfere.Firstly, the system is constructed of such pipes, it does not look very aesthetically pleasing, well, at the initial stage of thin corrosion heat exchanger can become clogged.In addition, the price of installation of "black" pipe is not too different from the cost of the equipment of plastic and copper.

Modern heating systems are different from the previous, so the steel pipes, so to speak, now no longer in vogue.Often, the steel pipe is advantageous to use when required mechanical strength and large diameters.

Important: as they are suitable for the replacement of "black" pipe, that's the only choice, it is desirable to stop on a galvanized version.

Calculation diameter pipes ↑

to create a full-fledged heating system should be familiar with the theory, in particular the principle of calculating the appropriate pipe diameter.When wiring pipes, this parameter is very important, correct calculation helps to avoid unnecessary heat loss and energy consumption wasted.

pipe diameter - the size of which determines its size;You can carry out self-assessment, it needs to know some parameters: internal diameter fittings, fitting, and a nominal rate of internal diameter and wall thickness.For example, increasing the diameter of which is used to increase the area of ​​heat transfer means results in a pressure loss and heat loss.

diameter calculation is made on the various formulas and schemes, traditionally used to measure the kind of inch system.Calculation of the diameter depends on many factors: the pressure in a dilution tunnel, composition and quality of the coolant.All formulas are hard to remember, so it's best to go the easy way and use the calculation table, everything is clearly indicated and coolant parameters and the circuit wiring pipes, radiators and characteristics.

can make the correct conclusion that it is not necessary to ignore the calculation, as each particular system is tied to the instruments used, and uses a specific coolant (water, antifreeze, artificial coolant) and also takes into account the way the circulation in the heating system.

types of pipes for heating: which is better?↑

heating system of the steel pipes and cast iron radiators has lost its leading position and gave the palm to the other materials and technologies.This is not surprising, after all, life and science are not static, they are constantly moving forward.So what to choose for the heating pipes of the monastery, that was the quality and reasonable price, and save the family budget?Now let's deal with this issue.

Metal-- a universal solution ↑

This effective combination of properties of plastic and metal pipes.Such excellent harmony is possible because of a specific design: the pipe consists of a base made of aluminum alloy, which is coated with high density polyethylene.This outer layer is characterized by high resistance to aggressive environments.

Typically, metal-plastic pipes commonly used as supply hot water as well as floor and radiator systems.Their main distinguishing feature - a small thermal expansion coefficient, it allows for the installation to significantly increase the distance between the supports and if they can do without the use of expansion joints.

Metal pipes
Metal pipes - decent option

composition pipe design has a number of advantages:

- 100 percent impermeability of gases;

- high bandwidth;

- excellent resistance to tearing;

- aesthetic appearance, easily fits into the interior space;

- long service life;

- low installation costs;

- the possibility bezsvarochnogo connection;

- a great flexibility;

- are not subject to corrosion.

But there are some downsides:

- under the influence of UV plastic pipes are destroyed.

Important: To stop this process, it is necessary in the field of the effects of wear special protection, ie corrugated pipe.

- restriction in the choice of diameters.

This type of pipe is connected by means of threaded or compression fittings by gluing.

Copper pipes - long tradition ↑

Copper - material for pipes, which is actively used in the late 17th century until today.This trend is not surprising, as this is a good option for heating.

for producing such copper pipes used only the highest quality, with almost no impurities, so the copper pipe is characterized by strength and high corrosion resistance.Sometimes the surface is covered with PVC pipe or polyethylene layer.This measure has a positive effect on reducing heat losses when the hot water passes through the pipes, and no condensation at the cold water inlet and improved appearance.Copper tubes are hard and soft.

The choice tubes
copper pipes have a long list of benefits and the only drawback - the price

copper pipes have such advantages:

- good thermal conductivity;

- corrosion strength;

- bactericidal effect;

- excellent operating temperature range: -200 - +200 degrees;

- when pressures and freezing systems are resistant to rupture;

- high rate of throughput, because the inner surface is very smooth;

- impermeability to oxygen;

- long life (100 years);

- aesthetic appearance.

Well, the only negative on the background of advantages - high cost.

Steel - the best option for budget ↑

Until recently, steel pipes rest on the laurels of the championship, but the old days have passed, today they are much less popular.Just ahead there was no alternative, and now it is available.

In terms of mechanical strength and a small percentage of the expansion of steel pipes do not have worthy opponents in the heat and steam heating.High thermal conductivity is the main criterion for creating a form of radiant hot water heating.

Steel pipe
galvanized steel pipes is recommended before installing

But there are disadvantages, and they are significant: steel pipes corrode, for their protection, you can apply the technique galvanizing.This option is the most ideal for domestic use.Once these pipes are heavy and awkward to use because of headroom.A montage involves the use of gas welding.But if a major aspect of human choice in favor pricing policy, such a solution is optimal.

Stainless steel - wide range of applications ↑

Such pipes are made of stainless steel and are worthy of attention.With proper use of stainless steel pipe more than compensated by the initial costs.Their main advantage - corrosion resistance and durability.This is not a "black" pipes, which are oxidized and become clogged with rust, this tube, though expensive, but cost-effective.If you do not have to use them for the umpteenth time to acquire and change the fittings, valves, plugs and the like, while berating unscrupulous manufacturers.

Stainless Tube
Stainless steel pipes - a symbiosis of strength, reliability, aesthetics and long

In addition, the range of application of stainless steel pipes spectacular "warm floors and walls", boiler connection and many other areas.Savings on the face, it is better to spend money once, and then enjoy the benefits obtained.

Plastic pipes - new technologies ↑

These pipes must be chosen carefully and with great responsibility, because the reliability and durability of the heating system depends on their quality.

Plastic pipes are manufactured on modern equipment and in the production process using new advances in science.As a result, the output is a product that meets building codes and standards.These tubes not only reliable, but also cheaper to assemble.It does not need any expensive equipment, and further maintenance works do not require large cash investments.It should be noted that the plastic tubes maintain their performance over the entire service life, but also they are not subjected to adverse chemical or physical manifestations.

The choice tubes
Plastic pipes made of polypropylene - reliability plus easy and quick to install

heating system, which is based on the use of such pipes can be easily repaired and beautiful decoration materials, so that in this respect there are pluses.With plastic pipes can without any problems to implement complex projects, because the battery life more than 20 years.
