How to choose an economical electric battery for your garden?

Taking into account the peculiarities of energy supply to different regions of the country, we can conclude that not all villages use gas as the main type of fuel. Previously, it was mainly replaced by firewood or coal. But recently, solid fuels have begun to fade into the background, and electricity has taken the lead behind gas.

The thing is that manufacturers of electric heating devices began to offer so-called smart devices with which you can reduce the consumption of expensive electric current. Electric radiators fall into this category.

What types of wall-mounted electric radiators are there for a summer residence?

Electric batteries are especially relevant in areas where there is no gas supply. Installing wall radiators allows you to do without connecting an electric boiler, installing heated floors or installing expensive water heating systems.

Mounted batteries, regardless of type, can be installed independently. They are easily connected to the electrical network and do not require a separate boiler room. In addition, heating with such devices avoids problems with system freezing. Next, we will consider the types of wall-mounted electric radiators, their pros and cons.

Wall-mounted electric convectors

In convector-type devices, heating occurs due to the natural circulation of air masses. Since convector radiators do not have sections, the speed of air movement is slowed down and damped. Because of this, heating of the premises is slower.

How the convector works:

• At the bottom of the tin body there are holes for cold air to enter. There are holes at the top through which heated air exits.
• Inside the housing is a heating element that heats the air passing through it.

Pros:

• easy to install;
• affordable price.

Minuses:

• the heating element is not closed and burns dust contained in the air - carbon monoxide appears;
• consumes a lot of electricity;
• makes the air dry;
• due to insufficient convection, additional fans have to be installed;
• heating elements often break.

Infrared wall heaters

These electric batteries are a panel with a heat exchanger installed inside. Heating occurs due to infrared radiation. Such devices have a significant area, otherwise they would not be able to heat anything.

Infrared devices generate long-wave radiation that is harmless to humans. The convection of such batteries is comparable to conventional convectors that do not have sections.

Pros:

• warmth that is pleasant for a person;
• ease of installation;
• affordable price.

Minuses:

• not suitable as main heating;
• insufficient convection;
• high power consumption.

Electric masonry radiators

Stone batteries look like ordinary cast iron or tubular radiators. They have a sectional structure with a distance between the ribs of about 2 cm and provide quick heating of the room.

The heating elements are located inside the stone. They are completely insulated and do not burn dust. Stone electric radiators heat a room mainly by convection, but they also produce long-wave infrared radiation, similar to that emitted by humans.

Pros:

• good natural convection;
• high level of fire safety;
• easy installation;
• efficiency and energy saving;
• reliability;
• no pipes needed;
• can be left unattended.

Stone heaters have one drawback - they are more expensive than their convector counterparts.

Wall oil batteries

Oil heaters are inferior to the two previous types of wall-mounted radiators. They should not be left unattended, much less used as the main source of heat. Such devices have many sections, which ensures good convection.

Pros:

• heat the room well;
• affordable price.

Minuses:

• fire hazardous;
• unreliable;
• high energy consumption;
• not suitable as main heating.

Oil heaters are recommended to be used exclusively as an additional source of heating. And most importantly, they must remain under the control of the owners of the house all the time they are working.

Advantages and disadvantages of oil heaters

Among electric heating devices, oil ones are the only ones that are called electric radiators. Oil heating has many advantages:

• does not dry out the air;
• radiators transfer heat mainly through thermal radiation;
• has a safe design;
• the surface almost never heats up above 50-60 o C;
• easy installation and management.

All this is true, but there are also disadvantages. The main thing is a fairly large inertia. Oil, which serves to transfer heat, has a high heat capacity. And until it warms up, the air will not begin to warm up. But this same property allows you to smooth out temperature differences when turning on/off.

The biggest problem is high inertia and low efficiency: too many heat transfer stages

The second disadvantage is that the safety and durability of the work depends on the quality of workmanship. An incorrectly designed structure can simply burst when heated, the seams are poorly sealed, and oil will leak. Therefore, buying cheap but unknown brands is a risky business.

What to look for when choosing electric radiators?

To choose a wall-mounted electric heater that best suits your needs, it is important to compare the parameters of the room, the stated needs and the capabilities of the equipment.

DO NOT BUY Radiators Until You See THIS!!!

Parameters that you need to pay attention to when choosing wall-mounted electric radiators:

• Device power. If you choose it incorrectly, it will either be too hot or, on the contrary, cold. The calculation can be done with the help of specialists, using ready-made formulas or an online calculator. For example, for a room with a ceiling height of 3 m, 1 kW of power for every 10 square meters is sufficient. m to obtain an output temperature of +20…+23°С. For regions with harsh winters, the recommended norm is 1.5 kW, for the southern regions - 0.5 kW per 10 sq. m. m.
• Installation method. There are stationary and mobile heaters. Some are hung on vertical structures, others on horizontal structures.
• heating element. Their service life is approximately 15 years. But there are models with longer operating times. Such heaters are more expensive, so they are rarely used for summer cottages.
• Nutrition. Electric wall heaters require a separate power line from the panel. It is recommended to purchase convectors that have an electronic thermostat. They are more sensitive to temperature fluctuations and can change the power of the radiator.

Device design

Anyone who sees this heating device for the first time notices its similarity to a conventional aluminum heating radiator, which is installed in a water heating system. In essence, this is true.

An electric radiator is a sectional aluminum battery into which a heating element is inserted. A heating element is installed in the lower cavity of the battery; the device must be equipped with an automation and control unit.

Plain water or technical oil is poured into the radiator. In the first case, the heating rate increases, in the second, the indicators of safe operation increase.

The most amazing thing is that, like regular sectional radiators, electric radiators can be built up in sections. True, in this case it will be necessary to increase the power of the heating element. The device is supplied with a Mayevsky faucet, a bottom plug, and an electrical cord with a plug for the socket.

Which convector is the most economical?

The efficiency of modern devices powered by electrical energy today depends mainly on the cost of electricity. In general, all electric wall-mounted heating batteries have high efficiency, but due to increased prices for electricity, they are unprofitable as the main source of heat.

Wall-mounted, and any other electric heaters, are inferior in efficiency to other heat sources. Among their kind, the most economical are models with a thermostat, which allows you to set the desired temperature in each room and change the power consumption.

Principle of operation

In its operation, an electric radiator obeys the law of heat exchange. Cool air differs from warm air in having a higher specific gravity, so it sinks down due to convection. At the same time, heated air masses rise upward. The process of convection is that during the movement of layers of air, its lower level warms up to the required temperature.

The higher the temperature, the lower the specific gravity, which means hot air rises higher. This process is constantly repeated in the same sequence, provided the heating device is working.

Oil for oil heater

The question of what kind of oil is in the heater rarely has to be decided, since these devices are always hermetically sealed to prevent evaporation and leakage of the working substance. During operation, replacement is required extremely rarely.

If depressurization occurs, then adding oil will not be enough; first you need to repair the housing and solder the leak. After the seal has been restored and if there is a technological hole for filling the liquid, it is possible to refuel or change the oil.

You can pour various transformer, mineral automobile (transmission) and sometimes even used oils into the oil heater

It is important to remember that you should not mix oils of different origins in the radiator, because

An unpleasant reaction may occur (precipitate will form, the composition will thicken, etc.). Only substances of identical composition may be added. It is not recommended to do this on your own. It is better to carry out repair work in specialized service centers.
