How Do Oil Filled Radiators Work?

Oil filled radiators are designed to provide steady and consistent heat. The unit is filled with a special heat-conducting oil that circulates through the radiator’s panels or columns when the device is turned on. The heating element warms the oil, which in turn radiates heat into the surrounding air. This method ensures that the unit remains warm even after being switched off, making it more efficient compared to some other electric heaters that cool down immediately.

The process relies on both convection and radiant heating. The oil acts as a heat reservoir, maintaining warmth for extended periods without needing continuous energy input. This not only provides a cozy environment but also helps reduce energy usage, making it a budget-friendly choice for many households.

Are Oil Filled Radiators Expensive to Run?

One of the most common questions is related to running costs. While the initial cost of purchasing an oil filled radiator might be higher than some alternatives, the long-term operational savings are worth considering. Their ability to retain heat means they require less power to maintain a comfortable room temperature, translating to lower electricity bills.

To calculate running costs, you should consider the wattage of the radiator and the price per kilowatt-hour (kWh) charged by your energy provider. A 1,500-watt radiator running for one hour would use 1.5 kWh. With the right settings and intermittent use, the cost can be much lower than other heating methods.

How Long Does It Take for an Oil Filled Radiator to Heat a Room?

Heating time depends on the size of the radiator and the room in which it’s used. Generally, oil filled radiators take about 5 to 15 minutes to reach their peak temperature. Once warm, they distribute heat evenly and maintain that warmth for several hours. The built-in thermostat helps the radiator turn on and off as needed to maintain the set temperature, contributing to both comfort and energy efficiency.

Energy-Saving Tips for Using Oil Filled Radiators

To maximize the efficiency of your oil filled radiator, consider the following tips:

  • Set an Appropriate Temperature: Keep the thermostat set to a moderate temperature to avoid excess energy use. A temperature between 18°C and 21°C is typically comfortable for most homes.

  • Use a Timer: Schedule the radiator to turn on only when needed. Using a timer helps prevent unnecessary heating during hours when the room isn’t in use.

  • Choose the Right Size: Ensure the radiator is suitable for the room size. An oversized unit wastes energy, while an undersized one struggles to maintain warmth efficiently.

  • Position Wisely: Place the radiator in a spot where it can distribute heat evenly without being obstructed by furniture or curtains.

  • Keep Doors Closed: To retain warmth and reduce energy loss, keep doors closed when using the radiator. This will help the space maintain its temperature for longer periods.

  • Avoid Using Max Settings: Running the radiator on its highest setting continuously can consume more energy. Instead, start at a higher setting and reduce it once the room is warm.

  • Regular Maintenance: Clean and maintain the radiator to ensure it works efficiently. Dust buildup can affect its performance, leading to higher energy consumption.

  • Unplug When Not in Use: Always switch off and unplug the radiator when it’s not needed to prevent standby energy consumption.
