To date, the device system is warmwater floor is becoming increasingly popular, as it allows you to create a home coziness and comfort. This design consists of piping with hot water, which are below the floor surface. It is quite simple, it is connected either to the heating system or to the common hot water supply. However, not everyone knows which pipe is better for floor heating.
This heating system is preferable thantraditional central, since the hot air flow is evenly distributed, rising from the floor surface, 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, in contrast to the electric version, is more efficient.
The main advantages of this flooring system include the following:
There are such floors and disadvantages. These include the following:
Increasingly, the issue of floor warming comes down tothe use of not only heat-insulating materials, but also a special design, which includes pipelines, fasteners, manifolds with fittings, pump. It can be used not only as an auxiliary heating, but also as an independent system. In a small room, the installation of such a system can be done on its own. In this case, the question of which pipe is better for a warm floor will certainly arise. To answer it, you need to consider the principle of operation of such a heating system.
In this heating system, the main heating element is considered to be a concrete plate (thermally insulated) into which pipelines with hot fluid circulating through them are mounted.
To find out which pipe is better for a warm floor, you should understand its design features:
And in conclusion, the system must be brought intoworking condition with the help of equipment for transmission of coolant through pipelines (distributors of heating circuits, pump, control systems — valves, thermostats, servo drives).
There is an opinion that warm floor can reducewater pressure floor below. This can happen, but only in old buildings with gravitational water supply systems and only if the pipe is installed without complying with the required diameters and slopes.
If this heating system is closed,your neighbors will not be able to determine that they have taken some water. However, it is worth remembering that in residential buildings, unauthorized connection to the hot water supply system or central heating is strictly prohibited.
In the system of warm floors coolant temperaturemust not exceed 55 ° C. At elevated temperatures, the floor surface will become excessively hot, which is uncomfortable for the feet. Also, elevated temperatures can lead to cracking of the cement screed and deformation of the coating.
Having dealt with the purpose of this system, it is necessary to consider the types of pipelines.
There are many options, of which most often pipelines are used for underfloor heating:
Today the most commonMetal and plastic pipes are made of cross-linked polyethylene, in contrast to expensive steel corrugated and copper products. But polypropylene pipelines are more often used in water supply systems. For these purposes, they are more suitable - they are characterized by low cost, ease of installation, the ability to perform complex assemblies and branches. Therefore, a warm floor made of polypropylene pipes is better not to mount.
These are composite multilayer products thatconsist of five layers. The outer and inner polyethylene layers are tightly interconnected with special aluminum foil by means of glue. This pipeline is designed specifically for floor heating systems and has the following advantages:
This is a durable flexible product today.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 "crosslinked" ("REH"), and the system itself is called a crosslinked polyethylene pipe.
Choosing pipes "REH", you need to pay attention to the degree of crosslinking. According to the standard, it should be at least 65%. Such pipe "Rekhau" for a heat-insulated floor has a number of indisputable advantages:
When comparing cross-linked pipelinespolyethylene and metal-plastic it is clear that they have almost identical characteristics. However, metal-plastic products have a high thermal conductivity and heat up faster, but their cost is higher than that of cross-linked polyethylene pipelines. At the same time the pipe "PEX" for a warm floor has a greater heat transfer, which allows you to lay it with a large gap.
In any case, both types of these pipes are considered reliable and high quality, they meet modern requirements, and most importantly - are ideal for floor heating systems.
Pipelines for floor heating systems shouldchoose thoroughly. After all, they are not laid for several days, but for many years, so it is recommended to pay special attention to their reliability and durability. The ideal option in this regard are metal-plastic products and pipes made of cross-linked polyethylene. To date, the operational parameters they have no competitors. They are easy to lay, they are the most popular, and most importantly - their cost is low.
When choosing, there may be one singleThe question is which pipe is better for a warm floor - 16 or 20 mm? Experts advise the use of pipes with a diameter of 20 mm, focusing on consumer reviews and their own experience in installing such systems.
Pipelines of different materials differamong themselves not only characteristics, but also cost. The most expensive of them are copper products. Pipelines made of cross-linked polyethylene and metal-plastic are much cheaper.
On average in Russia, their cost is inrange from 50 to 150 rubles per square meter. Considering the price of the remaining components, about 2,000 rubles per square meter of heated area, which implies impressive costs for the room as a whole. But if we compare the water floor, made of pipelines of cross-linked polyethylene (or metal-plastic), with an electric one, then the first one functions from the boiler, therefore it will be able to pay for itself after 5 years.
