If you’re looking for a way to stay warm without running up your electricity bill, an energy-efficient oil-filled radiator could be just what you need. These heaters are great for keeping rooms cosy without the sudden temperature drops you get with fan heaters. Plus, they hold heat for longer, so you’re not constantly switching them back on.

Are Oil-Filled Radiators Cheaper to Run Than Fan Heaters?
If you’re looking to keep warm without running up your energy bill, an oil-filled radiator is usually the better choice. Why? Well, unlike fan heaters that blast out heat and cool down the second you switch them off, oil-filled radiators hold onto heat for much longer. That means even after you turn them off, they’re still warming up the room—without using more electricity.
Fan heaters, on the other hand, work fast but burn through energy just as quickly. They’re great for short bursts of heat, like warming up a small space in minutes, but they don’t maintain that warmth. So if you need steady heat for a few hours, an oil-filled radiator is way more efficient.
Are Oil-Filled Radiators Suitable for Large Rooms?
Yes, oil-filled radiators can be suitable for large rooms, especially if you choose a high-wattage model (around 2,500W). They provide steady, even heat that lasts longer than fan heaters. If you’re heating a big space, placing the radiator centrally and keeping doors closed will help trap warmth and make it more effective. For very large or open-plan areas, you might need more than one unit for the best results.
Tips to Maximise Energy Efficiency and Reduce Costs
If you’re using an oil-filled radiator, you want to get the most heat for the least money, right? Here are a few easy ways to do that:
-
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.
