Heating a private house is always a difficult task. Most often, the consumer is faced with the task of choosing, which is better to use: electric boiler or convectors? In this situation it is necessary to analyze all the advantages and disadvantages, calculate economic benefits, KKD, calculate the possible nuances. There is no universal solution, the right choice is the most adapted option, which will take into account a number of nuances:
- regular visits to the house;
- square, which must be heated;
- duration of use of the premises;
- financial opportunities.
Description of electric convectors
Convector heaters are a new generation, which combines a well-thought-out design, easy operation and installation, universal or exclusive design.
The operation of the convector is simple: in the lower part of the rectangular body of the device there are structural holes, through which the device receives cold air. Under the influence of the heating element air masses are heated and, according to the law of physics, rise, freeing up space for the cold. Thus there is a natural movement, or convection, air masses.
Electric convectors (there are also water and gas) completely ready to use and fairly easy to operate. That the device started to work, it is enough to install and connect to the mains. The advantages of these heaters include:
- easy installation;
- easy to use;
- functionality;
- reliability;
- environmental friendliness and safety for the human body.
Environmental friendliness is ensured due to the relatively low temperatures of the heating elements. Unlike classic heating radiators, convectors do not burn oxygen or dust, do not dry the air (more about the scheme of action - how the electric convector works).
installation of an electric convector
Convector heaters are easy to install. The body of the device reaches low temperatures, which allows you to mount the device anywhere, without fear of spoiling the decorative finish, interior. Electric convectors are divided into types by the method of installation:
- universal;
- wall;
- floor;
- built-in.
Universal convector heaters are attached to the wall on brackets or installed on the floor. The complete set includes legs or rollers. The universal method of installation allows you to change the location of the heater. Fastening of a convector can be carried out by the hands.
Wall models are installed similarly universal, except for the complete set, which does not provide additional legs for installation on the floor. But if the design allows, they can be purchased separately. The device can be mounted next to decorative elements or on a delicate decorative finish, but it should be borne in mind, that warm air moves from the device vertically. It is not recommended to place flowers over it, pet houses or any items, which can overheat or block the flow of warm air masses.
Built-in models of convector heaters are installed in a special niche in the floor at least 20 cm deep. The upper part of the heater is closed by a lattice. This type refers to stationary, can't move phone. Usually, built-in heaters are used for non-residential premises - exhibition halls or shopping centers, where the convector creates a thermal curtain. In private homes, such devices are used in those cases, when the walls are made entirely of glass. There are also models, which can be built into window sills.
Convectors heat the house
Convector heaters are often used to heat the house. Such devices, in most cases, do not require installation. Devices are installed in rooms, corridors, loggias, connected to the mains.

The lack of special manipulations during installation is compensated by the relatively high energy consumption, as well as complete dependence on it. By the way, there is a benefit here. In case of problems with the network, one petrol is enough (diesel) medium power generator, to start at least one convector. That will be enough, to keep the building warm, the pipeline did not freeze.
When the house needs additional heating, the convector will be the competent and rational decision. Heaters are compact, easy to install or move (for some species). The functionality of most devices allows you to adjust the power and intensity of heating.
pay attention! It is not recommended to save on the number of devices. Insufficient heating of concrete structures leads to the formation of excess moisture and mold. Naturally, it all depends on the climate, but this problem is quite common for owners of this type of device.
The appearance of heaters is rarely taken into account, but in the case of this type of heater, this point can not be ignored. In the range of stores you can find a variety of universal models, stylish convectors of the average price category. But you can create an individual order, when the manufacturer applies to the image panel, or line it with natural stone. The latter option is the most expensive, but suitable for those, who subtly calculates and plans the design of the premises.
Pros and cons of convectors
so, what are the advantages of heaters of this type:
- no installation costs;
- possibility of installation only in necessary rooms (and - disconnection of devices in the closed or unused rooms)
- mobility (plus take up little space);
- ease of operation, available to everyone;
- convective heaters can be placed in any room, including bathrooms or switchboards;
- large selection of options and additional features;
- security, environmental friendliness;
- external aesthetics.
Of the disadvantages are the following:
- inefficiency;
- cost (in some cases).
What is an electric boiler
An electric boiler is a heating device, the principle of its operation is to convert electrical energy into heat. The heating element affects the flow coolant, circulates through the pipes of the heating system. Simply put, shadows come into contact with water (or other chemical liquid), moving along the pipeline, heating it. Radiators, in turn, warm the air.
There are electric boilers on several grounds. By type of installation devices are divided into:
- wall;
- floor.
By types of heating elements:
- tenovy;
- electrode;
- induction.
Induction electric boiler
Also, the models differ in power (energy consumption) and functionality. The most affordable and simple, contain valuable heater and starter equipment, medium-functional equip with temperature control and monitoring units, and the "top" are controlled remotely.
pay attention! Models with tones can have a two-circuit system, which will provide the house not only with heat, but also hot water.
The heat carrier is distilled or salt water, and in induction boilers you can pour antifreeze. In both cases the cost of the liquid is quite low.
Description of heating elements of electric boilers
Types of heaters should be considered in more detail, used in electric boilers. Some values can significantly affect the choice of the appropriate model.
Tubular heaters are used in various devices: dishwashers and washing machines, convectors, as well as in electric boilers. The elements are completely immersed in the coolant and transfer heat to them. Among the advantages are low cost and easy replacement of shades, failed.
There are some disadvantages of such heaters, example, if the element is not completely immersed in the coolant, then it burns out quickly. Scale forms on the skin, which slows down heat transfer a bit.
Induction type is quite significant (as the equipment itself, and its components), but this is offset by the increased efficiency of the device. Heating is carried out due to the influence of the magnetic field (similar to induction electric stoves) on the heat carrier.
The design is quite durable, internal mechanisms do not wear out, except for the control unit. If you plan long-term use of the heater, example, permanent residence in a country house, then this type of system will be optimal.
Electrode boilers are demanding in the composition of the coolant, water must not be distilled, and with salt content. Moreover, the rate of content is calculated after measuring the current. Here you have to carefully study the instructions, and determine the optimal water composition.
boiler installation
Compared with the convector, electric boiler is much more difficult to install. If convector heaters are completely ready for use after purchase, then the electric boiler will require assembly and installation of the pipeline. And you should first analyze and plan, where it will take place, in what premises it needs to be got. Certainly, this will require additional costs and time, therefore for heating by electric boilers, preparation must begin in advance.
Despite the complexity of installation, cannot be argued, it is better to use a conventional convector instead of an electric boiler (or similar heaters). The piping system heats the air with its entire surface, and convectors provide local heating. Speaking of the pipeline itself, then aluminum elements can be used as radiators.

The boiler itself does not take up much space, looks aesthetically pleasing, but devoid of decorative properties. Usually, it is mounted in a separate or utility room. Because it will not always be appropriate to look in the kitchen or in the room.

Economic indicators and comparisons of heating devices
What is more economical: boiler or electric convector? It is worth noting, as the first, and the second option - energy consuming. But the actual cost is affected by the area of the room, dimensions of heat loss, and characteristics of a particular device. The average calculations in both devices are approximately equal: square 20 m? will demand 2 kW of power, and the house in 100 m? - no less 10 kw, which will be approximately 240 kW per day.
Analyzing the characteristics of electric boilers, it is possible to draw a conclusion, that this type of heating system is similar to the usual, as in high-rise buildings, and is stationary. Costs and time for laying the pipeline will be required only once, whereupon, the adjusted system will not require special manipulations. But such a system is not mobile, the convector can be moved or switched off, unlike an electric boiler. Pipeline, theoretically, it is possible to optimize and install additional valves to close the circulation of the coolant. In practice, this is quite difficult to do. Irrational boiler for small rooms.
This type of heater requires a stable and reliable mains voltage, if problems occur, then the heating will stop throughout the house. The generator can be an output, only if the power consumption of the device is on average 3 — 4 kw.
Convector heating systems are free of problems with the organization of work, and have virtually no disadvantages. The user can choose as a budget, and decorative model. The downside is that, that they do not have a single control center, more precisely, it must be purchased and configured separately. Walk around the rooms, adjustment and adjustment of several units, checking and maintaining them in working order - all this will at least take time every day.

In practice, users usually use convector heaters as a temporary and simple solution, until a permanent heating network is laid. Later, the devices serve as additional or emergency heating.
