Choosing a water pipe for floor heating , and produce their installation

In this article we will look at the main advantages and disadvantages of heating pipes, as well as show you how to choose the best water pipes for floor heating.

Heated floors with liquid coolant are very popular with the creation of heating systems in private homes and multi-family dwellings.Using the medium term water floor heating will be more economical than the use of electric heating, and this in spite of a fairly solid starting cost of the project.As the coolant in warm water floors commonly used hot water from the main heating systems.But in some cases as a special heat carrier fluid may be used, such as ethylene glycol antifreeze and that before being fed into the system is heated to the required temperature in a special device.

Pipes for water floor heating

Stack pipes for floor heating, or to trust the professionals?

Design and installation of floor heating with heat transfer fluid is quite challenging.The use of a heat transfer fluid imposes fairly strict requirements for pipes and reinforcing components used for its circulation.The pipeline system of warm water floors must reliably protect the system from leaks, otherwise because of microscopic holes you have to disassemble the large area of ​​the floor covering.Place leaking heated floor is quite difficult to find - the length of the pipeline system for a room area of ​​30 square meters can be up to a hundred meters.

Pipe laying water underfloor heating

However, despite the fact that the creation of the project and the installation of underfloor heating with heat transfer fluid requires professional work, you can make a contribution to this activity and discuss the choice of a technique of laying the floor, and characteristicsmaterials used.A special role in the creation of efficient and reliable hot water floor has a variety of tubes for circulation of the coolant.

What pipe choose?(Old technology to replace new)

recently for the creation of the pipeline heating system with heat transfer fluid used conventional water-gas pipes, which are laid on the floor with benders and gas welding.Formed design fits nicely on the subfloor and poured screed.In the case of latent defects, or appearance of a new whole floor screed had to be opened.

The use of metal-water pipes for floor heating

But with the emergence of a new generation of pipes for liquids - metal-polymer and the situation on the market floor heating with heat transfer fluid has changed dramatically.They have been widely used not only for the organization of water supply systems, but also for the construction of heated polov.Eti materials are on the market for more than twenty-five years, and more recently appeared in Russia.

apparent advantage of this type of pipe is more resistant to corrosion and durability of the inner layer to the abrasive action of the fluid.As a result, the inner diameter of the pipe remains virtually unchanged throughout the warranty period.The manufacturer guarantees trouble-free service life of such tubes for up to fifty years.The advantage of the pipe created with the use of synthetic materials and is a complete obstruction of the atmospheric oxygen, which allows them to be widely used in stand-alone water supply and heating systems where stability is particularly important elements of the entire system.

Plastic and metal pipes

plastic and metal-plastic pipes are usually sold in coils, which allows for optimal fit them planed for the required tasks.So when installing floor heating system with heat transfer fluid can blow the heat-conducting pipe without joints in the entire area of ​​the premises, which undoubtedly increases the overall reliability of the system.In that case, if the project warm floor water does provide connection pipes, they must perform the one-piece manner, which should prevent the occurrence of leaks.

Metal pipes

Besides plastic and metal-plastic in a number of projects to create heated floors and other materials used pipes.Thus, in recent years a certain popular Copper piping systems that have near-perfect heat transfer and total immunity to corrosion.

existing building regulations is forbidden to use when installing plumbing and heating systems, having direct contact with concrete piping systems made of ferrous metals - the life of such pipes surrounded by a concrete screed critically low.

scheme laying pipes for floor heating

Typically, the organization floor heating with a liquid coolant used pipes with diameter up to 18 mm.This value allows you to increase the thickness of screed on the floor for quite a small amount without substantial damage to the internal volume of the space.

quality of a pipeline system has a critical role - breaking floors to eliminate the minimum leakage is extremely labor-intensive and expensive exercise.

Guidelines for selecting pipe

When selecting pipes used for warm water floor pay attention to their purpose.Description manufacturer shall prescribe the use of straight pipe just for heating systems, not just for water, albeit with the use of hot water.

To navigate to the destination tubes remember that the pipes for the heating systems must meet the following specifications:

• -Have rate of linear expansion of no more than 0,025 Mm \ mK,
• -Have thermal conductivity rate of not less than 0.43 W \ mK.
• desirable for laying floor heating system to use one-piece tube section, without joints and inserts.

advantage of plastic pipes

To create a floor heating systems in residential buildings usually use two types of pipes: a polymer (plastic) or metal-plastic.

Polyethylene pipes Metal pipe

heating system has a structure "sandwich".The polymer layer it acts as a protective buffer, protecting from damaging internal components - aluminum pipe.The inner aluminum layer has a high resistance to solar liquid, the outer layer protects the aluminum from the devastating effects of the environment.

In principle, the characteristics of the plastic and composition pipes used for heating systems are roughly similar, so that much of a difference in the application of one or the other type does not exist.However, under the guise of the pipe to create heated floors unscrupulous sellers can sell you the usual water pipes.Their main function is completely different from specialized heating pipes - they simply deliver coolant to the heating system and are not intended for ambient heating environment.Therefore, the specialized pipes used in the outer layer of a special polymer, characterized by increased heat dissipation.

Composition pipe sectional

ordinary polyethylene, used in the water supply pipe has a thermal conductivity and, therefore, the use of conventional pipes in heated floors will give the lowest efficiency.

pipes with oxygen barrier

Furthermore, heating pipes created from polyethylene or from a combination of plastic and metal may be present and a special, so-called "oxygen" layer which prevents the ingress of atmospheric oxygen into the coolant.Otherwise - the air adversely affects the lifetime of the reinforcing components of your home heating system.

pipe structure with an oxygen layer

In this case we are talking about so-called "cross-linked polyethylene".The cost of manufacture of such pipes is different from normal in a big way, but their use is preferred when creating autonomous heating systems.
