Oil in heating equipment has been used for quite some time as a source of combustion and the corresponding generation of thermal energy. Today, gas mixtures are used in this capacity, and combustible liquids have passed into the status of a thermal conductor. It is on this principle that oil heating radiators work, in which tubular electric heaters (TENs) are also involved.
Design and principle of operation of the device
There are two form factors for radiator heaters - panel and sectional. Wall-mounted models are mainly produced in a panel version, that is, the structure is formed by two plates, between which a network of channels for the circulation of hot liquid is provided. The aforementioned electric heating element, a conductor of electricity, is also mounted in the tank, due to which the mineral filler (oil) and the environment are heated. So there is a natural convention, due to which the electric oil radiator fulfills its task. The wall panel design evenly distributes thermal energy due to a special alloy in accordance with user-defined parameters. Modern radiator control is implemented electronically with sensors and thermostats. The accuracy of the temperature setting reaches 0.1 ° C, but this is not all. Through a special display, you can see data on the presence of malfunctions, power indicators, electrical data, etc.
Oil wall radiator specifications
Choose a heater model according to several parameters, the main of which look like this:
- Power. It will help determine the amount of heat that a particular device can, in principle, emit. So, for a small room with an area of up to 15 m 2 , 1200 W will be enough, and for rooms from 25 m 2 - not less than 2000 W.
- Voltage. Although in standard versions such heaters operate on 220 V mains, manufacturers seek to optimize models for lower power consumption. At the moment, the most economical oil-filled heaters are designed for a low current of about 120 V. But for the safe operation of this equipment, a special adapter with a transformer is required.
- Sizes and weight. The thickness of the panel is usually 7-10 cm, and the length varies from 40 to 70 cm. The mass is usually in the range of 4-6 kg.
Design Features for Wall Mounting
The device is fixed to a stable vertical surface and does not involve further movements. Installation is carried out by complete brackets stationary. Therefore, two points should be considered initially: firstly, in principle, the possibility of fixing such equipment to the wall in a specific area, and secondly, accessibility to the outlet. What is the advantage of a wall mounted oil cooler, taking into account the mounting trouble? Such models are economical, small-sized, practically do not occupy free space and can decorate the interior with their design. On the other hand, there is no possibility of moving the unit; one cannot count on zonal heating of them anywhere in the house and, in principle, on a powerful thermal study (drawbacks of the operating principle and low-power design optimized for vertical installation).
Oil-filled electric radiators LVI Produkter
The Swedish line of radiators, which is presented in Russia under the names MEC / Yali. These are models of wall mounted oil heaters with electric heating elements with power from 800 watts. The manufacturer uses vegetable oil as a coolant. The temperature range of heating varies from 5 to 80 º. In this case, it is possible to separately lower the temperature directly to the surface of the housing for safety reasons. This feature is usually characterized by convection devices. LVI products also have a protection class of IP-44, which leads to a high degree of insulation and reliability of the oil heater. The price of the MEC / Yali model is also high - an average of 15-20 thousand rubles. This is explained by the fact that the devices are for the most part designed for continuous operation in harsh conditions - for example, in office and warehouse premises. However, ergonomics and control functionality also allow the use of equipment at home.
Electric oil radiators "EffectEnergo"
This type of heaters is also produced by domestic manufacturers of HVAC equipment, among which is the EffectEnergo enterprise. It should be noted right away that to create individual heating systems this is the best oil heater - both in terms of energy efficiency and in terms of economy. According to experts, the standard EffectEnergo solution in this segment allows counting on electricity consumption of 0.18 kW / h at low power up to 600 watts. This is exactly the option for integrated heating, in which several radiators will be used at different points.
The system can be combined with the main sources of heating or completely design communications on electrical energy. Of course, with such an operation, the costs will be high, but you can save on installation work, complicated network maintenance and the cost of auxiliary equipment. The average price of the oil heater from EffectEnergo is 14-16 thousand rubles. At the same time, a high degree of radiator safety, environmental friendliness and a modern level of control with electronics are guaranteed. For example, for residential premises, a special “climate control” is provided on the sensors, which does not minimize the cost of electric energy, focusing strictly on basic user installations.
Resanta heaters
A well-known Latvian manufacturer, under whose brand engineering and climatic equipment is produced in Russia. Resanta's oil heaters have a wide range of capacities - on average from 700 to 2500 W, which allows them to be used both in commercial premises and at home. The most advanced models are provided with a built-in fan, which increases the heating rate of the air. By varying the heating parameters, it is possible to regulate the humidity mode without drying the air. The Resant heater control is implemented in both mechanical and electronic formats - at the user's choice. Adjustment can be provided through the thermostat, the choice of modes through the remote control, etc. The current status of the device is reflected in the control panel with the indication of individual parameters and the light indication.
Device benefits
This type of heater is in demand in a variety of areas of operation, which can be explained by the following advantages:
- Optimized design. Small size, easy connection and minimal maintenance costs.
- Support for modern controls.
- Energy efficiency. Taking into account the latest changes in the design, we can say that these are the most economical heaters, if we take into account the costs of maintenance. Gas and water equipment requires less investment in the main resource of consumption, but due to a more complex technical organization, the complex is more expensive.
- Environmental friendliness. Again, minimal harm during home use - the device does not emit any toxic substances, nor a burn with dust.
- Attractive exterior design. Manufacturers diversify the model, including due to the original implementation of the color texture and structural forms.
Disadvantages of devices
We could not do without weaknesses, since the equipment is quite low-power and limited in the possibilities of heat supply. As already mentioned, for complete heating, several wall-mounted oil radiators will be required, and with a single device only local local heating can be provided. There are certain safety nuances. Hot oil in itself is quite dangerous in case of depressurization of equipment. Similar risks are minimized today, but the theoretical probability still remains.
Conclusion
Compact heaters for home and office - a convenient and functional means of heat supply. Despite the relatively low productivity, the wall mounted oil cooler finds its place both at home and in heating public facilities. And if its shortcomings are clearly manifested against the background of different central heating systems, then the oil cooler looks quite confident in its niche of compact devices for heating. Especially considering balanced energy consumption and structural ergonomics.
