What Are Oil Filled Radiators?
Oil filled radiators are portable electric heaters that heat a room using thermal oil to store and distribute heat. They’re a common choice for smaller spaces or supplemental heating because they’re easy to use. The oil inside gets heated by an electric element, then circulates to warm the radiator’s metal fins. The metal then radiates heat, warming the surrounding air. This process continues even after the radiator is turned off, providing a steady, gentle warmth. These radiators are known for their quiet operation and are a safe option for homes.
Oil filled radiators are known for being energy-efficient and safe, making them a popular option. They don’t use a lot of power, so they help save on energy costs, especially when used for short periods. They are also known for being portable, so they can be easily moved from one room to another. This makes them versatile. However, their heating output is often lower than central heating systems, which may not be ideal for larger spaces or colder climates. Let’s explore their details in the next section.
How Oil Filled Radiators Work
The heating element inside an oil filled radiator heats a special type of oil. This oil has high thermal properties, meaning it can store a lot of heat. This heated oil circulates within the radiator, warming the metal fins. The fins then radiate heat into the room. This process allows the radiator to continue radiating heat even after it’s unplugged. The oil inside the radiator is sealed, so it doesn’t need to be refilled. These radiators are designed to be safe, with automatic shut-off features to prevent overheating.
- Heating Element: This is the component that uses electricity to heat the oil. It’s typically a metal coil.
- Thermal Oil: A special oil with a high heat capacity.
- Metal Fins: These fins increase the surface area for heat radiation.
- Thermostat: Controls the temperature of the radiator.
The heating element is the heart of an oil filled radiator. It converts electrical energy into heat energy, warming the oil inside the unit. These elements are usually made of nickel-chromium alloy because of their ability to withstand high temperatures and resist corrosion. The size and power of the heating element determine the radiator’s heating capacity. They are designed to be energy-efficient and safe. The element is usually encased within the radiator’s design to prevent direct contact, enhancing safety. Over time, these elements can degrade, affecting the radiator’s performance.
The thermal oil inside the radiator plays a key role, absorbing and retaining heat. This oil is usually a non-toxic mineral oil. It is chosen for its ability to withstand high temperatures without breaking down and its good heat transfer properties. The oil circulates within the radiator, carrying heat to the metal fins. Because of its high specific heat capacity, the oil allows the radiator to continue emitting heat even after it is unplugged. The oil’s properties also contribute to the radiator’s quiet operation, since there are no moving parts. The type of oil used is usually sealed inside the unit. It does not need to be replaced.
The metal fins are essential for efficient heat transfer. They are usually made of steel or aluminum, which are good conductors of heat. The fins increase the surface area available to radiate heat into the room. They are designed to allow air to flow between them, helping to distribute the heat evenly. The design of these fins also influences the radiator’s overall size and weight. More fins mean a larger heating surface, but it can also make the radiator heavier. The fins also help with convection, where heated air rises and circulates around the room.
A thermostat is a vital component that lets you control the temperature. This device monitors the room temperature and regulates the radiator’s heating element to maintain a consistent temperature. As the room heats up to the set temperature, the thermostat automatically turns off the heating element. When the room cools down, the thermostat turns it back on. Some radiators have simple adjustable thermostats, while others come with digital controls. These digital thermostats often have timers and multiple heat settings, offering more precise control and energy efficiency. The thermostat’s accuracy plays a role in the heater’s energy consumption.
