To make the internal parts of the convector invisible through the bars, the heat exchanger, as well as body, stop and control valves cover dark paint.

For information: carefully clean the gutter cleaner should be monthly, wet cleaning should be done regularly (at least once a year, before the heating season).

Regulation of heating the room. Heat transfer from the convector without fan can be controlled by changing the amount of coolant flowing through it (“adjustment of the water”). This is Thermostatic head with remote control.

Possibility of temperature control heating circuit, of course, helps maintain comfortable conditions in any weather and at the same time saves energy source, and therefore means the user. At the same time thanks to recent innovations to monitor the weather may itself water heater with auxiliary equipment, for example, using external power Clima Manager.

Given the changes in temperature in the cold, the water heater automatically controls the temperature of the coolant in the radiant heating system, ensuring a comfortable temperature in the room. Automatic control can save up to 35% of energy consumption.

In the process of upgrading this equipment is endowed with a kind of “artificial intelligence”. That, in turn, confronts the task of the designer to ensure an easy approach to the complex management. The whole wide range of settings, modes, all kinds of functions should be understandable to the user. Therefore, an increasing number of water heaters equipped with a warning system that reflects the modes and parameters of the equipment. This can be used indicators or display through which the water heater communicates with the host. Management of this boils down to a few functional buttons on the panel. It can also be done remotely, since the introduction of the latest developments allows you to control the water heater by means of sms-messages.

Design enables clothe them in protective casing, which harbors from foreign objects, and set the input filter for air cleaning from coarse dust. The impeller, usually well-balanced and mounted on rubber amortizes.
Axial (axial) fans apparently do not differ from those used in personal computers. These devices have good moisture protection, in pairs (opposite each other) next to the heat exchanger and implement its local airflow and the intensification of heat exchange process. The lack of axial fans is that they are not able to provide even airflow heating element.

Centrifugal fans (one or two) installed in the face of the convector. Their advantage is the ability to create a powerful stream of air that allows you to organize intensive heating of the room. Externally, the radial fan is like a snail shell. With the help of air is blown into the base of the gutter and through the structural elements of the shell, served with a heat exchanger. The widespread use of radial fans, perhaps hampered by a sufficiently high level of aerodynamic noise generated by them (blades strongly “hit” on the air).
Note that the noise generated by fan convectors, for some customers is of paramount importance, especially when selecting devices for living rooms. For auditory stimuli have a negative, often depressing effect on the human nervous system. It must be borne in mind that the relationship between fan speed, heating power and the noise is not linear – noise equipment is growing much more sharply than the heating power. Therefore, manufacturing companies usually recommend pick up coil on the power developed by them in part (from 50 to 80%) performance fan.

At the maximum fan speed embedded convectors should be included only in cases where the need is really very quickly raise the temperature of air in the room.

Canada PEX Plumbing Supply Company does not recommend any place convectors with fans in the living room.
Unfortunately, the data cited by the manufacturer of noise for the average buyer is usually enough. In addition, the reported information is not always reliable, especially in the brochures. Everyone perceives the noise in their own way and in addition there are two identical convector (due to individual design features) may vary significantly from the noise.

Convectors for dry and wet rooms are equipped with fans at 24 V.
Office space heating. Adjustment convector with fan, usually carried out by changing the air supply fan in the housing unit (“adjustment of the air”). As a result, able to maintain the temperature of the air at a given level, depending on the method of flow control.

The easiest way to implement this method, including turning off the fan. In this case, a thermostat, located in the control point of the room and, depending on the temperature requirements, on and off the fan (fans) in the case of the convector.

Of course, “cut in” the fan on full power (for example, in the bedroom at night) can not always.

If the requirements on noise are critical, it is proposed to use a more advanced stage system regulation, allowing manually set the flow rate, and hence the intensity of heating the room. Such a system allows the inclusion of convection on the rate of pre-specified user (chosen by a shift lever). The structure of a three-stage regulator, in addition to the thermostat, located on the wall, are still auto-transformer and switch.
The third level – speed automatic regulation of speed. The system itself determines when a sufficiently low speed, and when an operating heating facilities must use increased. The most important advantage of this method of regulation is a significant decrease in temperature fluctuations, due to thermal inertia of the heating system.

Finally, the highest level of comfort system provides smooth control. The microprocessor control unit allows very precise to maintain the temperature of air in the room, avoiding over-heat and electrical energy. This microprocessor can keep track of not only the temperature of the air at the moment, but the temperature on the street, and many other parameters.

Such regulatory systems, the possibilities which could easily have written a separate article, supplied convectors companies MOHLENHOFF, KERMI and KAMPMANN.

Trench Convector usually has a reliable corrosion protection. Traditionally it is made of “galvanizing” with polymer coating, like devices companies KAMPMANN (Germany) and KERMI (Germany).

Recently appeared on the market and have become more robust and resistant to corrosion of the gutters “aluminum” – in their manufacture particularly excelled firm KERMI (Germany).

If the fan coil is installed in the raised floor design, the quality of corrosion protection of the material from which made the gutter, in principle does not matter. Much more important is the quality Anticor gutter during installation of the convector in the cement-sand screed, especially when it is direct contact with the body (alkaline concrete destroys metal).

The most stringent quality requirements for corrosion protection trough makes sense to bring in all the cases where the heaters are designed for the pool or conservatory, where it is due to objective reasons can be flooded by water “in the most grating. Shells used here convectors should necessarily be provided with drainage.

On the possibility of using embedded into the floor convectors in heating or cooling can be judged only by results of detailed calculations carried out by forces which only professional – convector firms-suppliers, as well as design and assembly organizations who had experience with this technique.
To facilitate communication with the supplier, we consider the basic design elements embedded convectors. In this case we divide the devices into two groups: the fan, the activating heat transfer, and without a fan.

Dream designer!

Most built-in floor heaters used for heating houses, rarely – in the heating of urban residences. For the first time entering the field of view of the buyer in the store or on the construction market, such a device is usually perceived as a long low box, which has a lid in the form of decorative lattice. Under the grate, in the case (it is called gutter), installed heating air heat exchanger (pex tubing with a on her heat transfer plates), which is connected to the heating system – from contact with it rises the air temperature in the room. In addition to the heat exchanger in the gutter of the convector can be located with a small fan motors (one or several) to expedite heating facilities by intensive blowing the heat exchanger, as well as various regulating devices.

During installation of the shell embedded convectors hide in the floor construction. They are immersed in the cement screed (“give the sediment) or installed in the openings, arranged in raised floor. After laying the floor covering will remain visible only decorative grilles, flush with clean disposable surface. The uninitiated person entering the room, heated recessed convectors are unlikely to immediately determine where is the heat – is it really from the narrow “carpet tracks, spread out under the windows? ..

Designers find embedded in the floor convectors so longed embodiment of a battery of invisibility. And all because of the built-in heaters are able to organically blend with almost any decor.

Color grid embedded in the floor convectors can be adjusted to the color of the floor covering or other important elements of interior decoration at home: upholstery, curtains, wallpaper and color, etc. Fortunately, most manufacturers of convectors offer enough rich palette of shades of color possible lattices. Grids are usually made of aluminum (without finishing, anodized, or coated with a polymer coating), precious woods (oak, beech, mahogany, walnut, birch less) or plastic. Beam, which comprise the grille may be placed across the trench convector – a product similar to the ladder and is flexible (it is easy to roll up into the bay, which is useful, for example, when cleaning the room). Along the trough are the rungs of hard and semi-rigid aluminum grids (in the last line elements are fastened together with special flexible springs that allow strictly adhere to its size and not burden the design).

Serial heaters are in terms of a rectangular shape, their dimensions once and forever defined by the manufacturer. Thus, the width of the gratings is 140-430 mm, length – 800-5000 mm. But if the standard rectangular shape and dimensions of devices for some reason you are not satisfied, you can order a suitable option for specific space. ” Theoretically, recessed convectors can have unlimited length and curved shape. It is proposed to connect grids into their heads in the corners of the room (the corner of their joints from some manufacturers is only 90 °, while the other is in the range from 0 to 180 °). Convector can repeat the contours of the curved sections of walls (for example, in the bay), walk round columns, etc. To order grids with metal inserts, fixtures, electrical outlets and other embedded equipment.
From the standpoint of Thermophysics recessed into the floor convectors good. With a minimum amount contained in their heat exchangers of hot water they instantly respond to changing needs in the warmth of the room, providing a high level of comfort and savings on heating.

In qualitative convectors lattice heated to no more than 40-45 ° C, even if the coolant temperature is high enough. Consequently, prolonged contact with their surface can not get a burn. However, walking barefoot on the grating is still not recommended. Interior items, including leather sofas, chairs, antique wooden furniture and modern electrical equipment can often be located in close proximity to the convector without risk of damage. Passing through the device the air comes into contact only with small areas become extremely hot tube heat exchanger, a total area of 3,5-5% of the total area of heating, the plate markedly colder. Moreover, even at the maximum coolant temperature surface heat exchanger has a temperature of about 60 ° C, which virtually eliminates the sticking of dust and reduces (compared with other types of heaters) positive ionization of the air that adversely affects the health and well-being.

As part of any autonomous heating system, there is usually a water heater plant, which is intended for receipt and transmission fluid at different temperatures in different circuit. The water heater plant is not only the water heater, piping, connectors, regulating valves, pumps, actuators – that different regulatory system, which provides integrated management of all elements of the water heater plant to produce the necessary temperatures in different rooms and different thermal contours depending from external and internal factors.

For example, device management company WOLF consider the basic principles of water heater plants and heating system as a whole.

All device management, including the company WOLF, can be divided into manual and automatic, the latter usually have a manual control mode.

Manual control device for a single-burner R11 and R11-SB, provides manual adjustment of temperature in the water heater in the range from 38 ° C to 90 ° C. They have the security temperature limiter (STB), which disables the control system, burner in the event of overheating of the water heater, temperature controller, temperature indicator, the possibility of connecting the circulating pump heating circuit, temperature of the water heater.

Safety temperature limiter (STB) is present in any device regulation, as the manual and automatic, and ensures safe operation of water heaters and water heater plant as a whole. It is a sensor with an actuating device configured at a predetermined temperature off switchable 110/100 ° C and manual reset into position in case of alarm.

Control unit R11-SB is able to connect the horizontal and vertical water heater, a detached water heater, using a temperature controller SP-1. As a result, in manual mode is provided priority and hot water. The temperature of water heaters installed on the control unit R11-SB, or the water heater temperature controller SP-1.

To connect the two-stage burner device is used for manual adjustment R31-STAV, which has the ability to connect the water heater and hot water on a priority scheme.

Automatic control device (Automatic) WOLF presents Automatic R12, R16, R20 DigiCompact for single burner, R32 DigiCompact, R33, R33 / 4 DigiComfort for two-stage burners and RK-2, RK-4 for dvuhkotelnyh units with two and four mixing circuits.

All automatic control device WOLF controlled water heaters and water heater plants, depending on outside air temperature. So with a decrease in outdoor temperature will automatically increase the temperature of coolant in the water heater or in the serving line, and with increasing ambient temperature – decreases. All weather-control system contain a permanent electronic memory a series of curves reflecting the dependence of the coolant temperature from the outside air temperature. Each curve describes a heating system, insulation of buildings, climatic zone, the heating circuit. Therefore, simply select and install the necessary slopes for heating for all conditions. The best is the one indicator of the slope, which at the minimum outdoor temperature reached a maximum temperature of radiators, floor heating.

In addition to the control device it is possible to increase or decrease the temperature of the coolant, without changing the heating curve, and shifting it from the slope in the direction of greater or lesser temperature. All control devices have the additional regulation, which allows to quickly adjust the temperature of the coolant in the water heater in the event of a dramatically changed climatic conditions.

Automatic control device not only control the burner, ensure safe operation of the water heater, but also control various circuits and heating system as a whole. Adjusting devices R12 and R32 provide the work of one heating circuit and dhw priority. R16 – manages a single heating circuit, one circuit with mixer and provides heating water heater on the priority scheme. Automation R20 and R33 except the heating circuit and the circuit hot water control has two loops with a mixer, and R33 / 4 DigiComfort four circuits with mixer. Adjusting devices RK-2 and RK-4 are intended for two water heaters with two two-stage burners each. Have the ability to connect the burner stages, depending on the load, a smooth increase in water temperature in the water heater, electronic device control heating water heater. RK-control unit 2 controls two independent circuits with mixer, and RK-4 – four mixing circuits.

Adjusting devices series DigiCompact have great information display and two multifunction regulator, which allow you to quickly select any option and change it.

Automation WOLF provides seven modes of operation of the water heater and water heater plant. Mode to control the waste gas, which conducts a service engineer. Auto mode, when the water heater is working on one of the three programs stored in the memory controller, which can be modified according to individual requirements and at the same time is always possible to return to the standard program. Continued operation of heating, regardless of the installed program. Mode with low temperature or economy mode when the water heater automatically lowers the temperature of the coolant at the value that can be set individually in each case. The water heater can also be translated only in the regime of hot water with the heating system is turned off. Automation provides a manual mode, when the water heater provides heating fluid to the maximum temperature set in the parameters of the regulator, regardless of the outside air temperature. The controller has a mode of frost protection, by default, heating and hot water are included, but at the same time, a minimum temperature of the coolant to prevent it from freezing in the case of lowering the ambient temperature.

When you open the front cover control device can access the next level of management. Choosing the left regulator or that option, the right controller can change its value. At this level of control exhibited time, day, year, selected the program is the automatic mode; exposed temperature continuous operation mode or operating mode with reduced temperature, the slope of the curve of heating. Device control allows you to automatically switch the heating system from winter mode to summer and vice versa. Upon reaching the desired temperature in the summer control device disables the heating system, but it keeps hot water treatment. In automation provides the ability to view temperature regimes of different contours, as well as testing of all actuators.

Adjusting devices also have the level of control used service engineer to set the parameters that provide an autonomous and safe operation of the water heater and water heater plant. At this level, exhibited the minimum and maximum temperature of the water heater, the burner operating conditions, temperature limit protection of the heating system from freezing, modes of operation in the preparation of hot water, the influence of various factors on the contours of the heating water heater work and mixing circuit in economy mode.

Options at the level of control specialist may vary within specified limits, but apart from this there are factory set, which is always possible to come back and are fully ensure the efficient and safe operation of the water heater.

Device management firm WOLF have the opportunity to connect analog and digital remote control devices, which can be installed in residential premises for the convenience of management of water heater and heating system. Regulators have the opportunity to connect, through a special device, the phone that allows you to control water heater system with remote access.

The water heater plant is equipped with devices such regulation can operate almost without human intervention and provide the necessary temperature conditions in the room, depending on the season and the outdoor temperature during the day.

- Serg, what are the advantages of underfloor compared with conventional batteries?

- Agree that the battery is difficult to name an element that improves design. In addition, their use is uneven heating of the premises, and the floors are often cold to the touch. In underfloor do not have these disadvantages: laid radiant heating mats hidden from view, and the presence of the thermostat allows you to control the temperature by setting it within the prescribed limits. “Warm floors are safe to use, reliable and durable.

- They say the reliability of any design is directly proportional to its simplicity. Does this apply to cable heating system?

- Briefly explain the device of the system. It is based on the heating cable or heating mat that is placed on a rough floor at the stage of renovation. Control of the heating cable is controlled by a temperature sensor and thermostat, which includes the appropriate heating cable.

Our company offers a range of products of the company “Ensto” – heating cables Tassu, heating mats and kits StepMat StepKit, the scope of which depend on room size, type and material of flooring. These products are provided in the product group P90 on the price-list companies.

Obviously, when laboratory tests are not always able to reproduce the conditions that comply fully with the practice. In this case, the manufacturer is responsible for ensuring that the system proposed by the client, was a reliable and practical. This requires some experience and know-how in areas like manufacturing of PEX products, and installing them on site.

Despite the dominant role of the factor of reliability of the pipeline, which can be expected lifespan of 100 years, this aspect sometimes gets low priority because of the short-term benefits associated with the use of certain products, if the document confirming the permissibility of their use.

Mounting PEX fitting should occur, in general, in accordance with applicable directives and instructions for installation of the manufacturer.

The most important developer of products has been and remains the consumer. Only through his signals on the shortcomings of the product may solve problems that arise in practice, and its further improvement.
