Which pipe is best suited for the installation of warm water floor - overview

Perhaps someone thinks that the issue is not so significant, and given the cost of the entire system of warm water floor (and it is quite high), it is necessary to focus primarily on the price of the pipes?If so, this is a big mistake.Information - room 30 m² length of the route (depending on its circuit stacking) can be up to 130 - 150 lmWhere to look for a possible leak, because the pipes are hidden from visual overview of "finishing" coating?

Let us consider what the pipe is best suited for the installation of warm water floor, and which is not recommended.

Metal

not immediately reject the idea of ​​using metal pipes for water floor.Not to mention the high cost of "hardware", there are still a number of serious arguments against its use for the installation of "warm" floor.Let them briefly, as the lengthy explanation is not required.

First , susceptibility to corrosion.

Second , some roughness of the internal walls.Such defects although microscopic, but that is enough for the formation of different layers, which gradually reduces the value of this parameter is DN.

Third , a lot of weight (based on the length of the line in the floor).If no intermediate floors of the plates w / w (as in private homes is not uncommon), the factor is very significant.

Fourth , the difficulty of working with the material.Crop, adjust the size, bend, cut thread - it will require special tools.Plus - unreliable connections.Even tape FUM will last a long time, especially if the system is not pumped water and ethylene glycol, or antifreeze (and these fluids are often used in the circuits of autonomous heating systems).

Fifth , «Fill» articles of iron or steel concrete solution dramatically reduces the life of the system.For this reason, SNIP prohibit the use of such pipes, where they are to be in direct contact with artificial stone on a large extent.Therefore it is better not to risk it.

Pipes made of copper

They are characterized by excellent heat transfer, and do not corrode.But if you calculate how much it will cost the installation of such a loop, the desire to build the pipeline because of the material quickly disappear - as they say, "pleasure is not for everyone."

plastic and polypropylene

best option - a pipe made of polymers.It is found several varieties of these products, and even without such excellent performance as minimal thermal expansion and high thermal conductivity, they have a big advantage over metal counterparts - are sold in coils.This means that the contour of the floor of the water can be solid, without any connections.Consequently, completely eliminate the possibility of leakage across the packing area.

remains the last question - what kind is best to choose plastic pipes for floor heating?By and large - does not matter.The most commonly purchased products made of metal and plastic.The differences in their individual characteristics can be specified here - in this article, all painted in detail.

It is something else.Plastic pipe for water supply and heating - is not the same thing.If it is polyethylene, the floor heating should be selected so-called «linked» (REX) .Such products are characterized by high heat transfer, which is required for heating.The use of conventional pipe, plumbing, does not provide sufficient efficiency loop works.In addition, "cross-linked" polyethylene prevents the penetration of oxygen into the internal cavity, and thus to the coolant.

There is another kind of plastic - polypropylene.The cost of these tubes - the lowest, but their use is not desirable.The main drawback - in limiting the bend radius.It should not be less than the value "diameter x 8".Consequently, the distance between the "threads" will need to increase.This will lead to a decrease in heating efficiency.

Conclusion

• for circuit water "warm" floor the best option is to install pipes from the "cross-linked" polyethylene or metal-plastic.
• purchasing products should be clarified that it is intended for use in heating systems.
• To avoid further unpleasant "surprises" necessary to check the presence of a certificate.Given the complexity and high cost of repairs circuit associated with the dismantling of the flooring, "conducted" the low price should not be.A dishonest dealer can "deliver" the bay of ordinary water pipe under the guise of the heating and check forgery virtually impossible.Even an expert can not always find significant differences, since the materials are virtually indistinguishable visually.
