What is the difference between convector heater and oil heater

Which heater is better: oil or convector

Choosing between an oil heater and a convector heater, you must first understand the parameters of the room that needs your care. Once you understand this, whether you need a convector or an oil heater and which will warm you better.

The season of frosts and blizzards is only gaining force, so the heater may be needed more than ever. The default standard for a city apartment are oil radiators and convectors, it would seem: buy and enjoy. However, it is not as simple as it seems at first. Each type of heater performs its specific tasks, although it serves the same purpose. heating the premises.

To begin with, both oil and convector heaters are electrical heaters, so calculating the area of the room that these devices can heat is simple enough. You need to know the power of the appliance, which should be divided by 100 to get thus the maximum area it can heat. If your room has more than one window, the appliance power should be added to 100W or even 200W.

For example, if you need to heat a corner room with a floor space of 15 sqm, you don’t need to heat the whole room. M, multiply 15 by 100 and add another 200 W. As a result, you get the power of the device you are looking for. 1700 W.

Comparison

An oil radiator is an electric heater, which is a tank of oil and a heating element. Heating by increasing the temperature of the body by heating the oil. Heat radiates through the room. Can be installed on the floor.

Oil Filled Heater Vs Electric Heater [Pros & Cons] The Complete Guide

A convector is an electric device that is often hung on the wall or placed on the floor. The principle of operation is based on the convection of air masses.

Important! All heaters are assumed to burn oxygen in the room. This is not true, because there is no direct combustion process in both devices.

Determine what is better. a heater or convector, can only the user, depending on the specifics of the place and time in which the device will have to function. To understand this, a comparison of the convector. radiator pair should be made on the main and most important indicators:

  • economy. A radiator uses about a quarter less electrical energy than its counterpart;
  • heating time. The convector has a system in which the heating element immediately heats the body of the device. In the oil system, the heating duration is longer, because first the fan heats itself, then it heats the oil and the body alternately, which is a longer process;
  • convenience. Convector device is easier and more convenient to carry, because the weight is much less than its counterpart;
  • operating time. Oil tends to leak out through cracks and deformations. Therefore, this point is also not in favor of the radiator;
  • safety. Hot oil that splashes in different directions and leaks can not be safe, so the victory again for the circulating counterparts;
  • because with increased air circulation, the level of dust raised in the air is greater, so convectors are considered worse in the effects on human health;
  • prices. Oil devices cost much less than their counterparts.

What’s more economical, an oil-fired radiator or a convector

Feature of the oil radiator is the long time it takes to reach operating power. The heating element heats the oil, the warmed coolant heats the heater body and transfers the heat into the room. A large amount of electricity is consumed in the process.

The advantage of the convector compared to the oil radiator is that the use of less electricity compared to its analogues, about 25-30%. Using the new monolithic heating element further reduced costs by half.

The convector heaters

Convector differs from the oil radiator, even externally. at the top of the body there are guides for the output of warm air. Decorated with a thermostat, wall-mounted or floor standing. In the latter variant, the convector can have wheels, which allows it to move it around the rooms in a mobile way. The convector gives off heat not in the same way as an oil radiator. not in the form of heat cure, but due to the fact that the warm heated air rises up and disperses through the room through the finned guide rail. The front panel of the convector also radiates heat.

Stylish appearance is not the only advantage of convector heaters.

Silence is another advantage of the convector. Lattice fins evenly and quickly distribute heat in the heated room. Possibility of installation on the wall increases the useful area in the room. Convectors can be used not only for domestic purposes, but also for industrial heating of areas. The body of the convector, the so-called convection chamber, is equipped with a heating element, and warm air from it rises through the louvered lattice and enters the room.

The oil heater with his own hands

If you want to save money, you can make an oil type heater yourself. To assemble an oil heater with your own hands you will need only a metal case. Heating element and oil. The answer to the question what oil to use in oil heaters. purified and heat resistant.

This is to ensure that the walls of the heating element is not formed on the scale, and the oil itself does not boil at high temperature. If you need to know exactly what oil to pour into the oil heaters can and can not, then you should contact the professionals.

Useful tip! As a case for a homemade heater, you can use an ordinary cast-iron battery. The material has good thermal conductivity, and inside such a case you can easily install not only the heating element, but also a lot of other useful improvements.

The wiring diagram of the oil heater for self-assembly can be easily found on the Internet, and for greater efficiency you need to choose the correct heating element. It should be quite powerful, but without a magnesium anode, because because of it the heating element can quickly fail. Also when assembling it is necessary to understand the oil circulation pattern in the appliance.

To repair the oil heater with his own hands also need to understand the principle of operation of the device and the internal structure of the structure, as well as have special tools and skills, otherwise the repair can lead to a more severe breakdown. If you are not confident of your abilities, it is better to leave this task to experienced professionals.

Comparing an electric convector and an oil radiator

The principle of operation of an electric convector is very simple. In the lower part of the flat case there is a heating element. When turned on, it heats the air around it, which rises up. It is replaced inside the case by a cold stream. There is a convective motion, with its help, the air in the room is heated quickly enough. Some models have louvers that allow you to adjust the direction of the heated stream.

There are differences in the heating elements. There are also needle heaters (or stiches). On the outside they resemble long sewing needles. Stichi almost instantly heats up and works quietly, but also cools down quickly, does not tolerate contact with water, in a relatively short time burn out. The second option: tubular heating elements, they come in different shapes. It is a sand-filled steel bulb with a nichrome filament inside. Thanks to this, tubular heaters last much longer and can be used in damp rooms. However, they take longer to heat up and crackle unpleasantly when in operation. And the third type: monolithic heating elements, they can be distinguished by their X-shaped solid body. It has a nickel-chromium heating coil inside. These heating elements are devoid of the disadvantages of tubular and needle counterparts, but cost more.

Regardless of the type of heating element, convectors have a common set of advantages and disadvantages. Let’s discuss them all.

Pros of

  • Provides rapid heat to the room.
  • Compactness.
  • Safe operation. The outer casing of the device does not heat up during operation, it is impossible to get burnt.
  • Does not fear humidity and direct hit. Exception. equipment with needle heaters.
  • High fire safety.
  • The possibility of creating a modular heating system.
  • Convection currents actively transport dust. Needs to be cleaned more often.
  • Quickly lowers room temperature when the unit is turned off.
  • Unpleasant drafts appear at floor level.
  • The air becomes dry.

Which is better. an electric convector or an oil radiator. Comparison and differences in efficiency and safety.

In the absence of proper heating during the off-season in autumn and spring, or when the regular heating system can not cope with its duties, we all have to resort to additional portable heating devices.

In this case, if previously the choice was clearly in favor of oil radiators or small heaters, for lack of other safe alternatives, recently convectors become more and more popular.

Now that we have options, many people before going to the store begin to wonder which of these heaters is really the best? Is it worth spending money on a not really cheap convector or is it better to buy an old tried-and-true oiler?

Let’s deal with all the disadvantages and advantages of both devices.

This is probably the most classic type of heater. It works on the principle of heat transfer.

difference, convector, heater

In this case, there can be a significant heat loss.

That’s why, in order to warm up the whole room faster, it is initially placed almost in the center of the room. Shove it in a corner or lean it against a wall, you’ll be waiting for heat for a very long time.

over, the minimum distances from the walls and from surrounding objects are usually regulated by the safety regulations for placing such batteries.

If there is no air movement in the room, as long as the heated volume of air space near the heater passes to the adjacent layers, and they in turn give the heat on the chain, it takes a very, very long time.

Of course, if you sit near the radiator itself, it will be hot. But if you move to the sofa or an armchair, away from the radiator, the feeling of warmth disappears sharply.

As a result, it turns out that a comfortable and uniform temperature in a relatively large room (hall, bedroom) with an oil radiator can not achieve.

over, the bulk of the cold air flow, is always at the bottom. And the warm air from the radiator rises immediately upwards, in no way warming the layer under the floor.

Therefore, even having such a heater in the room, you still have to constantly walk in slippers.

A built-in mechanical thermostat is responsible for the question of periodicity of switching on and off oil batteries. Without such a device is not recommended to buy this type of heater at all.

So, because of the fact that the air near the battery is always much warmer than in the whole room, its response error of 3 degrees is considered almost the norm. Although sometimes it reaches 5-7C.

What problem does it bring to you personally? The trouble here is that the oil heater simply does not have time to react adequately to the speed of temperature change overboard.

As a result, you are constantly experiencing discomfort. The room will either be heavily overheated, or it will be periodically cool, even with the radiator turned on all the time.

This is not a matter of heat loss from the room, windows or walls. Namely in the incorrect operation of the heating device.

Electric Convection Heating Explained

This unit operates on the principle of convection. That is, it gradually mixes layers of cold air in the room with the hot. And it all happens without any fan.

These heaters are designed with a narrowed lower part and a wide upper part.

The heating element is on the bottom. There’s nothing else inside the convector.

The air temperature in the “air ” of this battery before turning on is the same as in the whole room. But once you plug it in, literally for 1-2 minutes, the heating element reaches maximum temperature and heats the “portion” of the air inside the case.

According to the laws of physics, the heat goes up, where it meets on its way the built-in louvers or shutters.

Bumping into them, the warm air at a certain angle is redirected toward the floor, where it immediately mixes with the coldest layer in the entire room.

And note, the shape of the air distribution louvers, can have a significant impact on the entire operation of the device. For example, with units where the louvers are similar to butterfly wings, the air will always be hot both above and below the convector.

The final comparison of the main characteristics

Still, which heater is better. convector or oil heater?

Oil heater or convector. each has its own advantages and disadvantages. Offers on the market and sales in recent years show that convection devices are rapidly replacing other types of heaters, because they are economical, comfortable and safe. And if we compare oil-fired radiators and electric convectors, then the latter are certainly in the lead.
