Understanding Different Types of Electric Radiators

Electric radiators come in various types, each offering unique benefits and functionalities. Here's a breakdown:

1. What are Thermal Fluid Electric Radiators?

  • Also known as oil radiators.
  • Feature a unique column design and are pre-filled with thermal fluids.

Key Points:

  • Take longer to reach a set temperature but provide lasting warmth.
  • May initially have cold spots, but warmth eventually spreads evenly.
  • Versatile and suitable for most interiors, including bathrooms.

2. What are Dry Thermal Electric Radiators?

  • Also called oil-free radiators.
  • Use lightweight heating elements such as aluminium for responsive heating.

Key Points:

  • Quick to install and reach the desired temperature, ideal for on-demand heating.
  • Offer fast, even heating without the need for thermal fluids.

3. What are Dry Stone Electric Radiators?

  • Commonly known as ceramic radiators.
  • Utilise ceramic stone to retain and emit heat.

Key Points:

  • Heat quickly and retain warmth longer, providing radiant warmth.
  • Ideal for larger spaces or areas that are harder to heat, like loft interiors.

How Do They Work?

Oil Filled Radiators:

  • Electrical elements heat thermal oil, which circulates through the radiator, heating its walls.
  • Radiant heat warms the air, causing it to rise and circulate, warming the entire room.

Oil Free Radiators:

  • Utilise advanced thermal components like ceramic or aluminium to generate and spread heat.
  • Similar to oil-filled radiators, they use radiation and convection to warm the room.

Which is Cheaper To Run?

Initial Purchase Price:

  • Oil-filled radiators might be more affordable upfront, but this can vary depending on brand, size, and features.

Running Costs:

  • Due to their quick heating feature, oil-free radiators could save more on electricity over time.

Maintenance Costs:

  • With no oil involved, oil-free radiators typically have fewer maintenance worries.


In the debate between oil-free and oil-filled radiators, there's no one-size-fits-all solution. Your decision should be based on your specific needs, budget, and room size.

Whether you prefer the consistent warmth of an oil-filled radiator or the quick heat and environmental benefits of an oil-free one, ensure you make an informed choice.

Consider factors like initial cost, running expenses, and maintenance requirements. By weighing these factors carefully, you can select the ideal radiator for your home, providing efficient and comfortable heating.
