Characteristic features of an electric convector
The electric convector, according to the data, is similar to an oil cooler. Convectors are used in apartments, offices, cottages, houses and can, in addition, be used as the main heating system. Suitable for any room. Most of the modifications have electrical protection, do not require special connection and grounding. The device is not afraid of moisture, which makes it possible to put it in the kitchen and bathrooms.
There is a certain risk of ignition without observing the operating conditions. The room is heated by the flow of air through the heater. The lower the electric convector is installed, the more successful its work.
The following heater designs can be selected:
-
Wall block with bracket. It is often placed under the window, creating a thermal curtain and thus preventing the windows from fogging up. - Floor device. Equipped with legs or wheels. You can place it anywhere in your room by the power cable.
- Universal device. It can be placed on the floor and on the walls. Complete with wall brackets and floor feet.
- Built-in devices. They are not visible as they are installed in niches in walls or floors and have a ventilation grill. Their placement is planned during the renovation of the house. The basic rule of connection is to provide an independent power source for each individual panel. The cross-section of the wire, depending on the power consumption: up to 1.5 kilowatts - the cross-section of the wire is 1.5 mm², more than 1.5 kilowatts - the cross-section of the wire is 2.5 mm². The circuit is protected by 30 MA UZO. The wire is placed directly in the panel and connected to a separate circuit breaker.
To use electric convectors and avoid unnecessary costs, make sure the hardware is installed correctly. Avoid drafts as they interfere with temperature control processes. This leads to overuse of resources and can lead to premature equipment failure.
Advantages and disadvantages of technology
Progress does not stand still, and today the heating of an individual building is no longer limited to a stove or a simple electric heater. Modern technology offers the owner of a private house or apartment many options for saving energy when heating. The advantages of electric convectors include the following:
-
budget; - easy installation and replacement of the device;
- there is no need to receive a variety of documentation and projects;
- precise temperature support;
- rapid heating of the room;
- beautiful appearance;
- small size;
- security.
The disadvantages are associated with rather high energy costs, but in fact the cost of heating convectors equipped with timers can be compared with the cost of heating even conventional gas boilers
Convector for any room
Electric heating is one of the most popular types of building heating in many civilized states. The heater is the lightest, most affordable, environmentally friendly heating method. Modern electric convectors can be used both as main and auxiliary heating. Liquid convection is often used as the main heating device.
There are such devices:
-
Dry electric convector. Structurally based on the principle of transferring warm air from a heating component (TEN) directly into the air space, the efficiency of such heat exchange is approximately 50%. In liquid convectors, heat is transferred to the liquid. The heat transfer efficiency of the liquid is approximately 98%. The lowest efficiency of a dry device for heating the same building requires more power than a liquid electric convector. - Liquid convector. The heated content carries its own heat to the entire plane of the heater, therefore, the heat exchange area of the liquid device is larger than the area of dry devices. Consequently, the surface of the heating component in a dry convector heats up more than in a liquid convector. The high temperature in the heat exchanger not only negatively affects the indoor air (dries it out), but also increases the use of energy.
When the air space heats up more than 80 degrees, the dust is burned, which carries with it reduction of oxygen in the space, therefore, the use of dry convectors for the main heating unacceptable. If it is necessary to completely heat the living space, it is required to select a liquid electric convector. The air speed depends on the height of the heating surface, which, as a rule, is higher for liquid convectors.
The transmission of dry convectors is often enhanced by integrated fans that forcibly blow air through the fixture's condenser. The disadvantage of the devices is their high noise. To heat a room with a dry device, it is necessary to concentrate on the power of 1 kilowatt to 10 square meters and with a ceiling height of 3 meters, provided that there is still a resource in the room heat.
If the heating system is equipped with liquid, it will suffice 700-800 W for 10 square meters, when an isolated room without additional heat sources. The heating temperature is changed using the control unit.
Some convectors are operated with a simple rotary knob. Such electrical converters are uneconomical and operate continuously in the mode set by the user. The most expensive progressive electric convectors are equipped with absolutely all types of meters, temperature controllers or programmers. If the air heats up to the required level, the heater turns off and on automatically, then the room temperature drops.
Summing up the above, the following conclusions can be drawn: dry machines are less economical, cannot be used as the main source of heat in a room, but are cheaper and easier.
Criteria for choosing a heating device
Choosing the right convector will help keep your building warm and comfortable for years to come. If you have no idea how to choose an electric convector, then you should know at least about the principles of operation of this device.
The principle of each device is based on the intake of cool air.which, when passing through the device, heats up and thus passes through the mesh at the top of the device. Air movement is based on the phenomenon of light convection, hence the name of the devices. Having risen, the warm air moves to the floor, from where it enters the electric convector again. Let's take a look at the key differences between liquid and dry electric convectors.
An electric heating convector equipped with a programmer is more convenient and economical. This makes it possible to program the device for the set temperature in the room for a certain time of the day, for each day of the week. The weekly programmer makes it possible to use the heater in the most efficient and economical way.
But not only the cost should determine the choice of heating systems. An important parameter is the heating zone indicator. Naturally, for larger areas or higher ceilings, it is necessary to install large electric heaters or to increase their number. With regard to energy consumption, this parameter should be considered in more detail. As you know, the higher the power of the device, the higher the class of energy consumption. Although convectors consume much less electricity than many other devices.
