Heating convectors: species differences, characteristics

heating convectors

When installing the heating system and to theHeated purchase instruments acutely the question arises how to install the equipment? Which is better, heaters or radiators? heating convectors - it is a relatively new heaters on the market today, so not everyone knows their main advantages and disadvantages, and therefore can not make a fully justified choice. In this article we will try to highlight some of the "dark" side of these devices and tell you about the benefits of specific types.

Classification convectors for heating

There are two ways to transfer heat from the surface of the heating element in the premises:

  1. By thermal radiation (cast iron, bimetal, aluminum radiators).
  2. Using convection currents (convectors).

The convection heat transfer devices is due to the constant circulation of air through the housing, usually a bottom-up, as much warm air is lighter than cold.

All heaters can be divided into several types according to location:

  • wall;
  • floor;
  • inside-water;
  • attachments;
  • universal.

The main advantage of wall and floordevices is the ease of installation. Convectors, floor heating simply placed on the floor and wall mounted to any vertical surface, which will be sufficient to drill a few holes.

Embedded underfloor heating convector

Installation of underfloor convectors embedded very complicated

But underfloor heating convectors require special training.

They are installed in pre-preparedniches, and for quality of work requires a certain baggage of technical skills and knowledge. In addition, installation of embedded water convectors takes a very long time.

Council: If you have not yet decided on a location or existing heating system can not cope with its main function and require the installation of additional heating equipment, the best buy convectors wagon heating. Such devices can be hung on a wall or installed in the most convenient place for special feet.

Depending on the heating method distinguished:

  • water heaters;
  • gas convectors;
  • electric heating convectors.

On the advantages of each type will be discussed in detail.

Convectors for water circuits

Already from the name you can guess thatcooled in such devices is water. Convectors heating water have replaced the radiator and batteries excellently gives off heat, but at the same time requires a large amount of coolant. Another problem faced by owners of ordinary radiators - air pockets formed in the system. Removing them - a rather unpleasant procedure, but in the water convectors occurrence of such a situation is impossible.

Design and Function

The convector is made from stainlesssteel, and its upper surface is covered with a lid. Depending on the design, this cover can either be removed or not. By heating pipes connected device available inputs on the side or the front side. All modern units are fitted with air damper, designed to adjust the intensity of the hot air mass, the air release valve and the valve that regulates the intensity of the heat by limiting the flow of coolant.

The main element - the heat exchanger - isa copper pipe on which the metal plates that significantly increase its area. In this case the ribs and the pipe must not be minimum clearance, otherwise the heat transfer is greatly reduced.

The principle of action is all the same propertyease of warm air. Only convectors, rising up, the air masses increase its speed by using a special fan. The design uses a very thin tubes, and as a material used for metal plates with a high thermal conductivity, allowing heat to complete the maximum power stated by the manufacturer is possible in less than 15 minutes.

Advantages and disadvantages

Disadvantages:

  1. Such devices can not cope with the heat the room with very high ceilings, as all the warm air will accumulate at the top.
  2. Perhaps the formation of drafts due to uneven air distribution.
  3. The circulation of dust convection currents.
  4. In rooms with heating water convectors not use forced ventilation. Taking the air near the ceiling, it will display all the warm air out.

Advantages:

  1. A good level of heating at low temperature coolant, that is, reduction of energy costs.
  2. Rapid heating.
  3. The light weight of the device allows it to be mounted on plasterboard walls.
  4. When installing the windows water convector completely cuts off the cold air coming from the outside, playing the role of the air curtain.

Tip: when buying water convectors pay attention to the housing and connecting hoses. They should be stainless steel to avoid corrosion.

Electric Convection System

These devices look very similar to the oilheaters, only a little over their body flat. Heating convectors electric wall mounted at a distance of 150 mm from the floor to a vertical surface (wall or partition), and in the presence of special legs are placed on the floor.

Mounted electric heating convectors

Tractor-mounted electric convector does not stop moving around the room, it takes a minimum of space

Design and Function

Inside the flat metal bodyis the heating element (heater), the entire surface of the plate is installed or he placed in an aluminum housing, designed to increase the surface area of ​​PETN.

Heating is carried out as follows: cold air through a small grille at the bottom of the device gets to TENu and warmed up, rises and escapes through the bars at the top. Electric heating convectors customer feedback output to the leaders also due to their quiet operation, as they are not equipped with fans.

Advantages and disadvantages of panel heaters

Disadvantages:

  1. A significant reduction in the heating performance and efficiency over time.
  2. Large power consumption.
  3. Not suitable for large rooms, recommended only as an additional source of heating.
  4. Heaters very dry air and dust spread.

Advantages:

  1. Low cost.
  2. Ease of installation and operation.
  3. Quiet.
  4. High efficiency - about 95%.
  5. Rapid heating of PETN.
  6. No special maintenance.

electric heating convectors - How to Choose

This question tormented by many consumers. First, you must define the area of ​​the dwelling and pick up the device, based on the ratio of 90 watts per 1 sq.m. Second, we specify what the thermostat is in the convector. Mechanical, of course, cheaper electronic, but it is less precise and is not able to react quickly to temperature decrease. Third, if you plan on heating the room with high humidity, it is necessary to buy heaters with IP24 protection against water.

Important: be sure to purchase the device with an automatic protection against overheating. This will avoid many troubles such as fire.

Gas convector equipment

gas heating convectors are simpleinstallation and operation. For their work does not require electricity connection, if the unit is not equipped with a fan. They can operate on LPG and natural gas.

The operating principle of gas convectors

The basic principle is unchanged convectors -air circulation in the appliance. Cold air enters the closed chamber and is heated by the combustion gas, the combustion products are released through the chimney into the street. Chimneys convectors are safe, even if the output from the wooden wall. They are a coaxial tube, through the central course of which stand out decomposition products during burning, and in the external circuit is the cold air, which prevents the heat of the chimney shell.

The advantages of gas convectors

  1. Easy installation - the device simply hung on the wall.
  2. Safety of operation.
  3. All materials used for production of convectors, environmentally safe.

Note: for the installation of the gas convector is necessary to invite experts from the gas companies.

Modern market range of convectorsvery wide. With proper selection of convectors can heat a small country house, spacious country house, slightly heat the room cool autumn evening, or create a system completely, and most importantly very quickly, raises the temperature of the room spun endlessly in the winter.
