How Do Oil Radiator Work?

Oil radiator heaters, also known as oil-filled radiators, are a popular type of space heater that uses oil as a heat-transfer medium. These heaters are known for their effectiveness, safety, and energy efficiency, but many people may not be familiar with how they work. After reading this research article, I am sure you will learn the mechanics of oil-filled radiator heaters for knowledge.

Work Mechanism of Oil Filled Radiators

Oil radiator heaters consist of a series of metal fins that are filled with ‘Diathermic oil’. The fins are connected to a heating element, which is typically located at the base of the heater. The oil acts as a heat-transfer fluid, carrying the heat from the metal fins to the surrounding air. This process is known as convection heating, When the heater is turned on, the heating element warms up, causing the oil in the fins to heat up as well. As the oil heats up, it expands, filling the fins and transferring heat to the surrounding air.

This technique generates a lot of heat and when the oil cools, it becomes dense and sinks back down to the bottom of the radiator. It is then reheated and the cycle repeats. This continuous circulation of heated oil creates a steady flow of heat that is distributed through the surrounding air, warming it. The good thing about oil radiators is that they distribute even heat throughout the room.

Also, most oil filled radiators come with built-in thermostats and other user controls features, allowing you to simply regulate the temperature and create a preferred heating schedule.

Do You Have to Refill Oil Filled Radiators?

Oil filled radiators typically do not need to be refilled unless they are leaking or the thermal oil has been drained for some reason. It is custom for all oil filled radiators to come filled with Diathermic oil that is sealed inside the fins and will not leak out or evaporate over time. Therefore it should not need to be refilled under regular use because it doesn’t consume for burning but rather used for heat output from the convection process.

To your concern, the Diathermic oil used within the oil-filled radiators is specially formulated to avoid oxidation or deterioration over time. It has a low vapour pressure, a high boiling point, and a low pour point. It can be heated to more than 300 °C without vaporisation under ambient circumstances, and it can be chilled to -60 °C without condensation.

This implies that even after many years of usage, the Diathermic oil in the heater will not evaporate or degrade. Furthermore, the oil in the heater is sealed inside the metal fins, so it will not leak or spill in typical circumstances, even if the heater is tipped over or moved around.

Just be cautious about safety, and it will last a long time. And, because the oil inside the radiator never needs to be changed, there is no maintenance necessary other than cleaning regularly.
