Today device water floor heating system is becoming increasingly popular, as it allows you to create home coziness and comfort.This structure consists of piping with the hot water, which is under the floor surface.It's pretty simple, connected either to the heating system or the hot water supply to the general.However, not everyone knows what is best pipe for underfloor heating.
This heating system is preferable to the traditional center since the hot air flow is evenly distributed, rising from the floor, and not just from the corner or from one side, as in the case of conventional radiators.It should be borne in mind that the water floor, unlike electric embodiment is more effective.
Advantages of underfloor
The main advantages of this system are as follows flooring:
- pipe under the floor heating provides uniform heating over the entire surface.
- no electromagnetic radiation.
- at low cost is possible to heat a relatively large area.The ability to hide
- heaters.
- Further service missing any costs
- One-time installation costs.
Disadvantages
available in these floors and disadvantages.These include the following:
- complexity of installation when there is a blow-pipe warm floor of polypropylene.
- the need for the water pump.
- The probability of leaks and problems with their identification.
- happens that neighboring apartments can "lose" temperature.
- In some cases the pressure drop in the riser.
- Difficulties in controlling temperature.
main function pipeline
Increasingly, the question boils down to the floor warming is not only the use of insulating materials and special design, which includes pipes, fittings, manifolds with fittings, pump.It can be used not only as an auxiliary heating system, but also as an independent system.In a small room the installation of such a system can be performed in-house.In this case, certainly raises the question of what is better for pipe warm floor.To answer this question, we must consider the principle of operation of such a heating system.
design floors
water in the heating system of the main heating element is considered to be a concrete plate (thermally insulated), which are installed pipes with circulating hot liquid on them.
To find out which tube is best for the underfloor heating, it should deal with its structural features:
- Nestle perfectly flat screed of cement-sand mortar.On top of it, along the walls, stacked insulation aluminum foil, which prevents loss of heat in the base of the walls and floor.
- top of the insulating layer by means of fastening elements laid pipeline.
- then design a solution is poured cement.
- top floor is laid.This may be a laminate, carpet, tile, etc..
And in the end the system must be brought into operation by means of equipment for the transmission coolant lines (heating circuit distributors, pump control systems - valves, thermostats, actuators).
Device features
Argued that floor heating can reduce the water pressure on the floor below.This can happen, but only in old buildings with gravity water supply systems and only if the pipe is installed without observing the required diameters and deviations.
If the heating system is closed, your neighbors will not identify that they have taken a bit of water.However, it is worth remembering that in residential buildings is strictly forbidden any unauthorized connection to the domestic hot water or central heating.
The system of underfloor heating medium temperature should not exceed 55 ° C.At elevated temperature is too warm the floor surface that uncomfortable for the feet.Also fever can lead to cracking and deformation of cement covering the coating.
So what's better for pipe warm floor?
dealt with the destiny of this system, it is necessary to consider the types of pipelines.
There are many options, of which the most frequently used for underfloor heating pipes:
- copper;
- of metal and plastic;
- corrugated steel;
- cross-linked polyethylene pipe;
- polypropylene.
To date, the most common are metal and plastic pipes and cross-linked polyethylene, in contrast to the expensive corrugated steel and copper products.But polypropylene pipes often used in water systems.For these purposes, they are more suitable - they are characterized by low cost, ease of installation, the ability to perform complex units and branches.Therefore, floor heating from polypropylene tubes is better not to mount.
Metal pipes
This multilayer composite products, which consist of five layers.The outer and inner polyethylene layers tightly interconnected special aluminum foil by an adhesive.This pipeline is designed specifically for the floor heating system and has the following advantages:
- Easy installation - the product perfectly folded, allowing it to lay spirals and snakes with a lot of bends.
- At a pressure of 10 bar maximum temperature reaches 95 ° C.
- Longevity - service life more than 50 years.
- keep their shape.
- smooth surface that reduces pressure loss.
- Excellent noise insulation characteristics.
- Resistant to chemicals and corrosion.
Pipe "Rehau" for underfloor heating
This strong flexible product to date is becoming increasingly popular.To give the polyethylene stability and strength it is treated under high pressure.As a result, additional molecular bonds are formed.This material is called "cross-linked" ("PEX"), and the system itself is called cross-linked polyethylene pipe.
Choosing pipe "PEX", you must pay attention to the degree of crosslinking.According to the standard it should be no less than 65%.This pipe "Rehau" for underfloor heating has a number of advantages:
- can withstand high differential pressure and temperature;
- flexibility;
- resistance to freezing during the cold season;
- strength - operational for more than 50 years;
- resistance to corrosion;
- easily recovers its original shape;
- ease of installation;
- low noise.
When comparing the cross-linked polyethylene pipes and metal-evident that they are characterized by nearly identical characteristics.However, plastic products have a greater thermal conductivity and heat up quickly, but the cost of their higher than cross-linked polyethylene pipes.This pipe "PEX" for underfloor heating has a higher heat output, which allows to stack it with a large gap.
In any case, both types of pipes are considered reliable and of high quality, they meet modern requirements, and most importantly - ideal for floor heating systems.
Professional Advice
Pipelines for floor heating systems should be selected thoroughly.After all, they are placed in a few days, and for many years, so it is recommended to pay special attention to their reliability and durability.The ideal option in this respect are of metal and plastic products, and cross-linked polyethylene pipe.To date, the performance parameters they do not have any competitors.They are easy to style, they are the most popular, and most importantly - their cost is low.
If you choose may be one question - what better pipe for underfloor heating - 16 or 20 mm?Experts advise to use a pipe with a diameter of 20 mm, focusing on consumer reviews and its own experience of installing such systems.
cost
pipelines of various materials differ not only performance, but also cost.The most expensive of them are copper products.Pipelines of crosslinked polyethylene and metal-are much cheaper.
in Russia on average their value is in the range from 50 to 150 rubles per square meter.Considering the price of other components, per square meter of heated area accounts for about 2,000 rubles, which means imposing the costs of the room as a whole.But if you compare the water floor, made of cross-linked polyethylene pipes (or reinforced plastic), with an electric, the first function of the boiler, so can pay for itself within 5 years.
