Flat radiator heating: characteristics, types, selection

Specialist shops offer a wide range of equipment for heating, including radiators. Flat variety became widespread among buyers.

Advantages of planar radiator

• Heaters save space inside the rooms, because they themselves are different dimensions, no more than the size of the window. This is important if the model is set next to the window sill. With flat radiators its width decreases. Buyers can decide how important that advantage. Designers are pleased with this decision.
• Batteries are known ability to collect dust. If the reduced thickness of the product - smaller and the area in which it accumulates.
• Flat batteries differ attractive appearance.

Dimensions heaters affect the heat transfer amount.

The apparatus and the characteristics of planar radiator

Experts agree that a flat should include instruments with a depth of two times less in comparison with the sectional models of the standard form.

Devices with panels of steel are often the group in modern stores.

For manufacturing steel panel assemblies using metal sheets. This material must pass through forging. Welding stamped sheets connect with each other. Thanks to these technologies are robust and reliable connection.

Small depth characteristic for each of the stamped sheet that is connected with the other design features.

1. Welded between a pane - the two planes in which a very high degree of heat transfer.
2. Devices characterized by a small internal cavity. It runs on the heat transfer medium, but it is not much. This feature is not only a virtue, but also a disadvantage. The positive side - is that the purchase of fuel does not require such high costs. Negative - that the need to support a certain temperature level, otherwise the area is not heated properly.

To solve the problem with the fuel consumption to the flat radiator fins added. They were called convection, and the connection itself - fins.

Spot welding is needed to secure more planes on the surface. For the cross section is characterized by the shape of a trapezoid.

Principle of operation

The upper part is a perforation. It is necessary to find out the heated air. Inside the housing there are metal tubes with the fins.

Circulating through the pipes of the heat transfer medium releases warm air. The path and goes through the perforation of a metal top, wherein the partially heated front surface of the metal. Because of this, more of the heat released.

Purpose - installation in open type heating, centrally recommend choosing other.

For optimal heat transfer media devices with a low pressure level. At temperatures up to 100 degrees is equal to 10 atmospheres.

dimensions

Mark is attached to the package, when the models supplied to the store. It lets you know to which group a particular device.

• Standard panel radiators without any add-ons are 10 type. A good solution for customers who need a simple kind. Smaller thickness can not be found on the market.
• The next type - 11. In appearance it is ordinary heaters, but on the one hand there are already attached convection fins. Due to this construction the depth increases.
• 12th type. The complicated construction consisting of many elements: two flat panels, and among them - the fins. Such devices have even more depth than the previous species.
• Type 22. With the fins in an amount of two parts, and with two flat panels. Depth is greater than in the two previous groups.
• The last type - the most complex, it consists of three panels. Fins set in three places. Two rows of ribs are set between the first and second panels. Another - between the second and third panels.

Each manufacturer has its own depth indicators.

Forms and types of flat radiators

Panel and sectional oil heaters.

For buyers interest is the flat panel variety, which is installed on the floor or on the wall.

Use as a coolant are not water, and mineral oil - the main difference between the device from other species. Compared to water, oil-cooling takes longer that becomes an advantage. Because of this long period for which the released heat.

Allocate and other advantages:

1. Simple installation instructions, for which it is not necessary to invite specialists.
2. Low weight, allowing to mount the structure on any wall.
3. Affordable.
4. A wide range of heaters for sale. Each device selects a suitable size.
5. The heated surface is not exposed to high temperatures. Careless handling can not be burned.
6. It does not dry the air, making the room retained a comfortable microclimate.
7. Low power consumption.

Wall-mounted electric heaters

Elements heating type are installed inside. The heat goes through the plates made of metal. Then the heat is released through the slit. Recent located in an upper portion of the casing.

The unit quickly heats the room, while there is a convection. In terms of operation, this category heaters universal. The best option for cottages, inhabited in summer or winter.

marking

The marking meet these letter designations:

• K - for the lateral connection type.
• Kv - for the bottom connection.

Heat transfer apparatus 1 meter in length will be 1.5 kW. But this characteristic occurs when the fluid is heated to 90 degrees.

In practice, different coolants not such a high temperature. Heat transfer in these conditions, less than 1 kW. If space heating is required another figure - set a few units.

installation

Planar radiator used for heating, which is organized forced circulation of coolant. They are put there, where the pressure and the movement created by pumps.

Flat radiators are placed for heating closed. As part of the expansion tank is necessarily present.

The process looks like this:

1. heat carrier begins moving through the pipeline under the action of the pump.
2. It passes through the valve.
3. It turns out consumers.
4. Goes on air vent.
5. It is sent to the return line until it reaches the expansion tank with the membrane.
6. The process is repeated.

Batteries of this type have a shorter life when they are assembled in the open. No need to constantly drained. Oxygen in the liquid is greater if it had just poured. Because of this, on the radiator actively influences the corrosion processes.

It allowed the installation of several radiators, walking one behind the other. Then, the heat output is reduced by 40 percent for each meter. After heat efficiency decreases after the second row. Design that looks like a single unit, it is easier to get, if you set the rows of radiators and provide top plates.

How to choose a flat heating radiator

• Planar heating devices are not relevant for circuits in which the coolant circulates naturally. Such heating requires large quantities of coolant. The panel radiators it is rarely sufficient for full functioning of such equipment.
• Radiators do well if forced circulation. The main thing - to choose the expansion tank, based on the required volume. Depending on the selected power and the circulation pump.
• Heating is not able to operate at a temperature above one hundred plus degrees. It depends on the operating conditions of the heating power of the appliance is purchased in the store. When incorrect counting will have to repeat the action again.

The house is not heated in winter for those who do not take into account this factor. Heating housing will cause additional costs. Each manufacturer is a table which shows the correction factors.

• Connection may be on the left, on the right side. On the right side is most often connected one pane models. Two-panel universal. Flat radiators with bottom connection are more expensive than the versions with the top. White - the cheapest, others cost more.

Sometimes the connection method used truck. This means, on the one hand the lower pipe is connected with the supply pipe. Return pipe is connected to it, too, but on the other hand. Radiators with connections give ten percent less heat than other schemes. Expansion plugs and mounting brackets are included.

Because of the low volume of liquid inside inertia remains the same. Because of this it is easier to establish joint work with devices for the automatic adjustment. New central heating system equipped with such often. Compared with cast iron, these models feature improved performance. They respond to signals from the control device without delay.

The challenge for the calculation of power, which is needed for the proper functioning rests on the shoulders of the designer. Necessarily captured heat loss through the building envelope.

• The correct choice of the model is possible thanks to the knowledge of the thermal power and height. Low heating radiators are selected, if the sill height does not permit the use of conventional models. When using the lower heating devices heat is distributed more evenly. Denser air curtain produced by the device.

Installation costs are reduced by using single-pipe layout. In this case, the need becomes a bypass line.

The air discharged through the valve, standing at apices. Access it overlaps the incoming water, and the output is automatic. Barrier to create a coolant shut-off valve, which is called detentorom. This increases the heat transfer. Without shut-off valve can not do during the repair work.

• When the one-pipe system, the diagonal wiring connection is more profitable. Summing up the coolant organize on the left side at the top. Abduction - at the bottom right.
• battery width is selected such that they overlap the windows by 50-75 percent. Narrow patterns do not form a dense thermal curtains. Because of this, do not cut off the penetration of cold air.
