The Radiant heating system with a lower bottling among the townspeople not uncommon. And it is not in vain, because, along with other Radiant heating systems it is distinguished by a number of characteristics that enable consumers to make his choice in her favor.
Let us consider the main advantages and disadvantages of this system, to see how beneficial and necessary to install it in urban apartments.
First of all, you need to pay attention to its structural features. Pipe systems are installed on the floor, so you will not have much thinking as they hide. Pipes can be something close. The main technological advantages should be made good heat transfer. This is all the same design features, that is due to the fact that the pipes are installed at the bottom, they heated floor and not a ceiling.
However, despite all these advantages Radiant heating holiday home with a lower bottling is far from ideal, as also has its drawbacks. Foremost among them is the resistance of the system. This means that for the normal functioning you have to acquire a very powerful pump, which would entail extra costs. Moreover, your costs will also involve the acquisition of materials for the installation of the heating system.
Also, with the lower heating bottling provides additional installation of special control valves and vent. And the vent must be exactly as much as radiators will be connected to the heating system.

Varieties of Radiant Heating
The popularity of these heating systems is constantly growing. For example, in Sweden 90% of newly built houses equipped with a heating system with Radiant Heating, in Finland - 50%.
There are two main types of warm floor: water and electric. Air floors, because of their exotic and expensive, will not be discussed. And water, and a PEX tubing warm floor one thing in common - a low temperature heater (the temperature of the floor surface rarely exceeds 30-32 ° C), very large area. Usually the whole floor area radiates heat.
However, if the room is planned to install furniture or equipment that will not move, then the warm floor beneath them is not done. The design of such floors is as follows. First is dirt or concrete base, then - a layer of warmth and waterproofing. Insulation laid on top of concrete screed with fuel elements: pipes of hot water or electric radiant heating. You may ask: "Why do you complicate things, when you can just hang on the walls of the battery?". Answers - for comfort.
The author has personally experienced something almost heavenly bliss, which provides such a system. Being in the house where the only heating was warm floors, I was surprised that the air temperature in the room did not exceed 18-19 ° C. In the yard - minus 24 ° C, and a general sense - all the comforts. The house shed a soft, pleasant warmth. Arrogant cat was not to banish from the tiled floor, where the animal warmed after a walk down the street.
The explanation can be found on the plot of temperature distribution depending on the height of the room. Everyone knows that under the traditional heating system (radiators and convectors) heated air rises and cools down, fall down. Therefore, the ceiling is hot, at the floor level is cool, but at the height of the head temperature is somewhere around 22-24 ° C.
A different picture emerges in the room if the heat source - the floor. There is also the warm air rises to the top. But there are significant differences: the temperature of batteries or convectors high - +70 ° C, with the temperature gradient is large enough, loud and the air velocity in the resulting convective flow. Inevitably drafts, because the size of radiators or convectors are limited, and the air is heated, rises strongly over the radiator and goes elsewhere. Thus, in the room formed by a constant and steady current of air, which moves together with the dust, pet hair and other household pollution. You have not asked ourselves, where so much dust in the closet?

Energy efficiency trends in the development of boilers
Energy efficiency trends in the development of boilers
Modernization of equipment, especially heating, aims to also take into account the public interest. Questions of cost and resource management are increasingly addressed at various levels. Developed various programs for "sustainable energy". They emphasize the state as a whole and each person in particular on the benefits of the introduction of more sophisticated equipment. Especially in the part of which is aimed at reducing energy consumption and environmental pollution. One way of moving towards a peaceful coexistence with nature is determined by the formation of information-oriented lifestyles.
In order for energy efficiency equipment shall be considered not only as a way to save money, but as a method of careful and rational use of resources at the state level are special projects. These documents are developed, on the one hand, to encourage manufacturers to use advanced technologies in energy consumption, on the other - raise awareness among consumers. In Europe, the operational directive 92/42/EES on demand efficiency for new hot-water boilers using liquid or gaseous fuels. According to the document, for they introduce a special mark showing the efficiency of the device match accepted standards. Equipment with the highest estimate of the effectiveness marked by four stars.
In the matter of saving as a separate item stands out the possibility of using alternative sources of energy. Many countries are actively using wind and sun, even when individual building. For example, at an exhibition contest "Solar Decathlon in Washington, was among the other submitted to the house, provide energy not only themselves, but also a small electric car. Many manufacturers of heating equipment take into account such a high popularity of alternative resources for modernization and provide an opportunity to use the boiler with a solar collector.
Environmental contamination is not equally urgent than energy. Emissions of nitrogen oxide formed during combustion of gas, toxic. In connection with this concern of various public organizations influenced the adoption of more stringent standards on emissions into the atmosphere. This in turn boosts the production to use technologies that minimize emissions of toxic components. Products in accordance with the volume of unwanted emissions are assigned to classes of security.
The modern experience of designing new boilers Specificity of heating equipment is the need for its installation and periodic maintenance. Therefore, serious producers in the process of developing a new product take into account both the needs of customers and specialists suppliers and assembly companies. In this connection, when designing a manufacturer tries to provide for improvements that would have made it a product suitable for professional work.
Primarily these changes relate to design features. Using the boiler starts with the installation, the simplicity of which is an important advantage in the eyes of a specialist. For example, all new line of boilers ARISTON built on a single platform that allows much easier installation and maintenance. There is also a new range of hydraulic connections to the wall and the chimney connection. In the interest of service technicians in the design of such methods are used placement of all components of the boiler (access from the front for most of them), which allow for viewing with minimal effort and time. As is known, except for the audit of the burner and control of flue gas should be a periodic recharge of the coolant. In boilers of new generation provides a solenoid valve recharge and built-in semi-automatic recharge, which makes this procedure easy and safe.
The issue of reliability in the design of giving one of the utmost importance. There was a major part in the process workers are assembling and service organizations, because they, when confronted in his work with the most urgent problems, suggest the main causes of breakdowns. Experts carrying out the installation, are interested in the longevity of the equipment not less than the users themselves. After all, frequent crashes of the recommended equipment they affect not only the credibility of the manufacturer, but also the reputation of the installer. According to Gabriele Montesi, "taking into account the climatic and other features of Russia can say: if the boiler works well here, so they will easily run everywhere. Therefore, any comments and suggestions of Russian specialists considered a priority, especially since it is a very qualified people. " Focusing on the received valuable information on the production technology was promptly carried correction (for example, added new protections against frosting smoke removal systems).
However, if it fails in the boiler, the main task specialist - correctly install its cause. However, this part of the renovation would address himself boiler, if it is equipped with modern diagnostic system. For example, the LCD display reflected an error code with an explanation, and in Russian. The system self-test also allows you to save the latest information about the fault required for the analysis of the equipment.
System GPRS, through which the user can control the boiler at a distance, makes it possible to establish a permanent electronic link with the service center. Such a system (E @ SY) has already been introduced in several Russian regions, in particular, in the Belgorod region.
As a result, upgrading the heating equipment has set itself targets not only the market, but also public. The effect of the development and introduction of new methods in the boilers to customers is reflected in increased comfort and the possibility of an individual approach to heating their homes, as well as savings in energy. Professionals distinguish features that are important to install and maintain. And for society, these changes - small but nevertheless a step towards environmental protection and energy-efficient use of resource potential.
