Oil heaters simulate a radiator of a central heating system. They consist of a hollow metal form, inside of which there is a heating element. The design is filled with mineral oil, it works from a network with a voltage of 220 V. Such a device is inexpensive. It is safe to use.
How does an oil heater work?
The layout of each oil heater is similar. The housing of the heating unit is metallic, consists of several sections that are hermetically joined together. Inside, the structure is filled with mineral oil, and outside it is covered with a layer of powder paint, which is very durable and not subject to mechanical damage.
The package includes:
- heating part (TEN);
- thermostat;
- heating regulator;
- wires
- overhead panels.
The principle of operation of any oil heater is the same. First, the wire is connected to the network, the heater is heated, then under the influence of thermal energy the oil is heated, then the case. The heat from the heated case is transferred to the air that comes in contact with it, it heats up and rises. By convector principle, a mixture of cold and hot air occurs, and its temperature rises. Some models are equipped with a fan so that the air change occurs more intensively.
Thermal energy heats the oil
Heating devices have different capacities and differ in the number of sealed parts. The room will heat up faster if the unit has more sections. In this case, the heater is heavier and larger. On all models, wheels are installed with which the devices move, so the heater's mobility does not depend on its size.
Oil convectors have a number of operating modes. To do this, switches are installed, and on some models touch control panels or liquid crystal monitors, which show data on the operation of the device.
How to disassemble the oil heater?
Before repairing the heater, the cause of the breakdown must be determined. To do this, you need to disassemble the unit, although outwardly it seems that the oil heater does not disassemble, since it is monolithic.
Important! Before starting repairs, the device must be disconnected from the mains. You can not include the design until complete assembly.
Disassembly procedure
There are many different models of oil heaters; there is no exact algorithm for parsing. But you can highlight the general rules by which the unit is disassembled faster.
It’s not difficult to disassemble the oil heater
First you need to carefully examine the convector control panel. The construction of a cheap oil heater is similar to an expensive one. Disassembly begins with the stage of unscrewing the bolts and removing the fasteners. On some models, instead of screws, there is a plastic panel that snaps into place with a spring. In this case, you need to feel the latch on the panel with any object in the form of a wedge (preferably made of plastic), press it harder and thereby bend it.
If the repair is done for the first time, then it is advisable to take a photo of the whole process. This will help to properly assemble the disassembled unit after repair.When removing bolts and screws, it is also recommended to lay them out in the order in which they were unscrewed. This will correctly screw them back into the radiator, in the desired sequence.
Can an oil heater explode?
Oil is not a flammable liquid, therefore there is only one answer: oil units do not explode. If the thermostat breaks, such an electric heater will overheat, the housing will be depressurized, and hot oil will leak, which may cause a fire.
Oil heater may cause fire
There are rules for the operation of oil structures:
- Do not use the appliances in bathrooms or other rooms where humidity is high.
- Do not cover the heater with fabrics. Overheating will occur and the oil will begin to leak.
- The device should be located at a distance of half a meter from the wall, as there is a thermal relay that disconnects the device in order to protect it from overheating.
- The heater must be positioned vertically during operation, because inside it is not completely filled with oil. If you put the device, then the ten will be exposed, this will lead to depressurization.
- Do not move the unit by pulling on the cord. It will come off and there will be a closure.
- The cord must not come into contact with a hot surface, because of this the insulation melts.
- In winter, the unit must be kept only in warm rooms.
- Do not use the appliance with a broken overheat sensor.
There are no categorical contraindications to leaving the oil heater overnight. This is one of the safest devices. But still it is recommended in such cases to purchase products with auto power off.
What oil is poured into the oil heater, the efficiency of the oil heater
Many people are interested in what kind of oil is poured into the floor oil heater. Transformer oil is poured into the section. It is heated by the heating element and circulates. Oil temperature can reach one hundred degrees Celsius.
The heat dissipation of the heater is very high. To increase the efficiency, fans are installed on the radiators, so that the air in the room does not dry out - special water evaporators.
The efficiency of the oil heater is 80%. With proper operation, the life of the floor oil heater is more than twenty years.

How to choose a device?
Problems with heating in the cold season can occur both in residents of urban apartments and in suburban private houses. It is necessary to solve the trouble in emergency mode with the help of electrical equipment.
Why not take care of buying an oil heater in advance? These devices are very reliable and safe to use. The heating elements are closed, therefore ignition is excluded. These designs were invented for a very long time, the principle of use has not changed.
The latest models have added several new features:
- light indicators;
- timers;
- fans
- humidifiers;
- temperature regulators;
- overheat shutdown sensors.
Oil heaters are divided into several types:
- Floor standing. These are the most common radiators.
- Wall mounted flat. They consume energy very economically.
- Board. These are low-power devices, have low heat dissipation.
Some models have a fireplace effect. They work silently and quickly heat the room. They installed traction on both sides, so the heated air circulates very quickly.
On modern models, there are blocks with programs and timers. In the presence of such a unit, you can set the on / off time. As a rule, new units are remotely controlled and have an emergency shutdown sensor.
The oil heater does not take up much space
When choosing a device, consider the following factors:
- Power. This is the main indicator. A power of 1 kW is enough to heat a room of 10 square meters. meters with a three-meter ceiling. If there are windows or doors, then we add 0.2 kW for each element.Indoors from 30 square meters. meters, you need to install several of these devices.
- Sizes. This indicator depends on the number of modules: the more modules, the larger the structure, the power of the device increases and the area of the heated room increases. This must be taken into account when choosing a similar technique.
- Design Features. This refers to additional functions that increase the usability of the device and increase the quality of its work. For example, the presence of a network indicator, temperature control mode, and more.
- Manufacturer. The manufacturer should also be considered. Brands that have long been on the market are known and recognizable. They guarantee the quality of their products and long service life.
When choosing a heater, you need to consider that the more functions installed on the equipment, the more expensive its cost and the more energy it will consume. Also, brands from well-known manufacturers are more expensive. It is necessary to determine the optimal price for yourself, and also take into account the functionality of the device. This will allow you to make the right choice.
