What Are Portable Oil Filled Radiators?
Portable oil filled radiators are a common type of space heater. They’re usually rectangular with several fins or ridges. Inside, they contain oil that’s heated by electricity. The oil then warms up the metal fins. These fins then radiate heat into the room. Because the oil retains heat well, these heaters stay warm for a while even after they’re turned off. They’re a popular choice for their safety features and gentle, consistent heat.
How Portable Oil Filled Radiators Work
Portable oil filled radiators operate on a simple principle: heat transfer. The heart of the system is the oil, typically a diathermic oil, that’s sealed inside the radiator’s fins. When you turn on the heater, an electric current flows through a heating element. This element heats the oil. The heated oil then circulates throughout the fins, warming them up.
These fins act like a radiator, slowly releasing heat into the surrounding air. The heat warms objects and surfaces in the room, which in turn warm the air. Because the oil takes time to heat and cool, these radiators provide a steady, consistent warmth. They are known for being relatively quiet and not drying out the air.
- Heating Element: The heating element is a critical component. It converts electrical energy into heat. Different radiators have different types of heating elements. Some may use a simple coil, while others use more advanced designs for efficiency. The quality of the heating element can influence how quickly the radiator heats up and its overall lifespan.
The heating element’s power rating is an important factor to consider when choosing a portable oil filled radiator. Higher wattage models will generally heat up a room faster. However, they also consume more electricity. It is crucial to match the wattage to the room size. - Oil Type: The oil used in these radiators is specifically chosen for its high thermal conductivity and stability at high temperatures. It does not need to be refilled. This special oil can safely reach high temperatures without degrading or creating dangerous fumes.
The oil is safely sealed within the unit. The use of oil helps to distribute heat evenly. - Thermostat: Most portable oil filled radiators come with an adjustable thermostat. This allows the user to set a desired room temperature. Once the room reaches this temperature, the heater cycles off. It then restarts when the temperature drops, maintaining the set level. This feature helps to save energy and prevents overheating.
The thermostat helps manage power consumption. It keeps the room at a comfortable and consistent warmth.
