As far as space heaters go, the oil-filled heaters are some of the most popular heaters we have in the market. This popularity, importantly, is not dumbfounded; there are genuine benefits that oil-filled german electric radiators provide homeowners, including exemplary safety, energy efficiency, and effectiveness.

Understanding Oil-Filled Heater

Typically, an oil-filled radiator has the form and shape of traditional radiators. However, they tend to be smaller in size, which is the main distinguishing factor they have. Oil-filled radiators have series of fins or columns that are joined together to form a closed lope. The columns or fins may have open spaces between them. However, there are atypical oil-filled radiators that are constructed of a single flat panel. However, in all of these varieties, the radiator elements are attached at the base and they all have a control panel.

The inside radiator columns, fins, or panel is filled with a diathermic oil, hence the name oil-filled radiator. However, the oil is not a fuel in any way or form. As such, there is no oil refilling required, something that many people do not actually know. The oil only functions as a heat reservoir. It only circulates through the radiator without diminishing.

The Working Mechanics of Oil-Filled Radiators

An electric heater, which is basically a resistor, is installed inside the unit. The function of the resistor is converted electricity into heat energy. Since the electric resistor is immersed in the diathermic oil, the heat that is produced is absorbed by the oil, warming up the oil. With increased heat, the oil begins to circulate in the fins, columns, or the flat panel. Thereafter, the circulating oil heats up the metal fins, which with increasing heat and oil circulation creates an even surface temperature of the radiator.

The final bit of the process is the radiation of the heat. Once the heat on the surface of the radiator increases, it begins to radiate into the surrounding area, warming the room. Natural convection takes on the role of distributing the heat.

Air Circulation Through Natural Convection

Oil-filled radiators typically operate without the need for a fan to distribute the warm air. Instead, they rely on physics to distribute the warm air. When the air around the radiator is heated up, the air molecules become less dense and thus rise up to the upper sections of the room. Concurrently, cold air from the upper parts of the room flow into occupying the space left by the departing warm air molecules and the cycle continues. Eventually, convective currents form. It is the continuous convective currents that distribute the heat in the room.

With this in mind, you can appreciate the silent operations of the oil-filled radiator. Since it does not have a fan, there is no stressing noise. Importantly, the heat distribution is so subtle that you would barely notice that it is happening. Only when you come near the radiator will you notice it.

The Advantages of Oil-Filled Heaters

Having acquainted yourself with working mechanisms of the oil-filled radiator, it is important to take note of its advantages. Below are some of the notable advantages of this radiator system.

  1. They Do Not Cause Dry Air – The system does not operate using a fan. As such, it does not dry the air in the room.
  2. Energy Efficient – All the electric energy that is supplied to the heater is turned to heat. This means that its energy efficiency is quite high. It also does not power a fan.
  3. Longevity In Heat Radiation – Even after turning off the heater, it still radiates residual heat slowly.
  4. Inherently Safe – he radiator is inherently safe as the metal surfaces do heat up to scorching levels. Thus even if you brush your hand or leg against the metal components, you will not be burnt.
  5. It Does Not Produce Fumes – Since there is no burning of energy sources, there are no fumes produced. This makes the system safer than conventional radiators.
