Pipes for hot water: tips on choosing and installing

Pipes

When designing the water supply of an apartment or house, it is worth paying attention to the fact that plastic materials have a certain operating temperature, which means that for hot water supply or heating systems it is necessary to select products with the required technical characteristics. It should be noted that some types of such structures can differ significantly in their characteristics. Therefore, before choosing plastic pipes for hot water, you need to have some knowledge about these materials.

Types and installation

To begin with, it is necessary to say that recently only environmentally friendly materials are used for these purposes. This is especially important if the pipes for hot water are made of plastic. There are special norms and standards that are used in the creation of these materials and their compliance is carefully monitored.

Products intended for heating have a special structure that provides them with additional thermal insulation.

Species

Most often recently used PVC pipes for hot water. They are quite practical, easy to install and even withstand high pressure. It is immediately worth noting that there are so many varieties of such products and they should be chosen in accordance with the required temperature regime, which is necessarily indicated on the material. (See also the article Single-pipe heating system: features.)

Plastic systems have almost the same appearance and differ only in labeling.

There is also a HDPE pipe for hot water.. It is believed that it is more resistant to temperature extremes and tolerates even quite intense heating.
It is also important to mention that almost all plastic pipes for hot water supply have a certain marking applied along the entire length with a certain interval.. In this case, the maximum permissible temperature must also be indicated through the permissible distance.

The pipe itself must indicate the maximum temperature it can withstand.

Metal products are also of various kinds.. However, it should immediately be said that modern installation instructions do not imply the use of carbon products and sometimes even doped materials. This is due to the fact that they can be harmful and have a very short lifetime, especially with occasional heating.
It is worth noting that metal-plastic products are also made in such a way that the metal does not have contact with water.. Therefore, most often to create such pipes using copper or an alloy called NMZH. It should be said that the price of such materials is very high, since they are additionally covered inside with a protective layer of special varnish.

Tip! The choice of a specific type of products is a matter for everyone personally, but experts recommend paying attention to modern developments that have already established themselves.

Hot water lines are insulated not only to prevent condensation, but also to save energy.

Installation

First of all, it is necessary to observe the distance between the pipes of hot and cold water. It usually fits in between eight and ten centimeters to eliminate the mutual influence of systems on each other. Otherwise, it is possible that condensate will appear, which in the end will result in a fistula on the hot water pipe when using metal structures. (See also the article Plastic sewers: features.)

Also, experts recommend using a kind of winding or housings designed to insulate pipes. In this case, such a procedure should be subjected to pipes for hot and cold water supply, in order to exclude temperature drops, which also lead to the appearance of condensate.

The entire basic installation of the system is made in accordance with the type of material selected. Therefore, if all work is done by hand, then you need to immediately pick up the necessary hardware.

Tip! Each type of material has its own types of insulation systems. At the same time they can, it is quite expensive that you need to consider when choosing a pipe.

Recommendations of the masters

If you choose the right material, the question of how to clean the hot water pipe will no longer be relevant. Therefore, plastic systems are gaining great popularity.
When designing a water supply system, you should not allow the intersection of hot and cold pipes. That is why a system with a high wiring temperature is located at the bottom.
Do not sew such lines in the box, which impede the flow of air. This will also cause condensation.

This arrangement of the two highways is considered unacceptable, although very often such products can be seen in modern apartments.

Conclusion

Having studied in detail the video in this article, you can learn a lot more about creating similar water supply systems. At the same time, based on the text above, it is worth concluding that in recent times it is better to use modern materials that are not only practical and reliable, but also cost a little less than old metal pipes.
