Oil filled radiators vs ceramic radiators: Which is best for your home?

Looking for the best electric radiator for your home? While both oil filled and ceramic radiators boast efficiency, precise control, and versatile aesthetics, there are some key differences that may make one better suited to your space than the other. So, let’s delve into how they work, what sets them apart, and help you determine which electric radiator is right for you.

Oil filled radiators explained

Oil-filled electric radiators are the go-to choice for many homes. A direct offshoot of central heating systems, they blend superior efficiency with showstopping designs.

How do they work?

Oil-filled electric radiatorsheat using an electrical element immersed in thermodynamic oil contained entirely within the radiator body. Pre-filled on delivery and engineered to spread evenly throughout the radiator, warmth is dispersed throughout the room via a combination of convection and radiation.

Key benefits of oil filled radiators

Suited to all-day heating

With improved heat dispersion, the thermal fluid reaches every part of the radiator, so the surface has a more even temperature. Not only does it equal a steady supply of warmth that lasts longer, it ensures there’s no risk of cold spots or overheating.

Great for a range of spaces

Suitable for both bathrooms and main living spaces, oil filled radiators are nothing if not adaptable. They’re particularly suited to larger spaces, since their uniform heating is designed to reach every nook and cranny of the room.

Versatile designs

Designed to encourage the heating process, oil filled radiators benefit from a diverse range of styles. While some on the market have been converted from central heating and fitted with a new element, our range has been built from the ground up to utilise the full potential of electric, ensuring optimal design and performance.

Ceramic radiators explained

Ceramic radiators offer efficient and convenient heating for a wealth of spaces. Many homeowners prefer them due to their compact & minimalist builds, heat-retentive technology, and an emphasis on delivering portable, fast-acting warmth.

How do they work?

Ceramic radiators use wire elements embedded into high-density blocks. These ceramic bricks excel at retaining heat, allowing the radiator to remain switched off for longer while still maintaining your desired temperature. Offering 20% more radiant heat compared to oil filled radiators, they’re particularly well-suited in spaces struggling to maintain consistent temperatures.

Key benefits of ceramic radiators

Responsive & robust warmth

Ceramic electric radiators heat up in just 10 minutes, making them an excellent choice for rooms requiring quick, ad-hoc heating.

50:50 heat transfer

Ceramic radiators emit an even split of fast-acting convected heat and long-lasting radiant heat. Infrared radiation directly warms people rather than the air, making them ideal for rooms that struggle with draughts or cold spots.

Flexible installation

Ceramic radiators can be DIY mounted to the wall in minutes. Many models also offer optional radiator feet, allowing you to easily move them to wherever warmth is needed.

Now you know the basics, it’s time to compare the two to help you pinpoint which is best for your home!

Costs & heating performance

Our selection of oil filled radiators have been meticulously crafted, designed from the ground up to enhance the convection process and built using the highest-quality materials. This commitment to excellence often translates to a higher price point compared to other types. While ceramic radiators maintain excellent quality, their manufacturing process is typically more streamlined, resulting in a lower initial cost. In terms of heat performance and running costs, both are equally efficient, boasting exceptional heat retention and providing a prolonged, even spread of warmth. The key distinction lies in their suitability for different applications.

Generally, a higher initial cost. Energy efficiency translates to stable running costs 

Energy efficient which results in stable running costs 

Heating performance 

Provides a steady, even heat over an extended period. Slower heat-up time – up to half an hour, but also means slower cooldowns  

Rapidly warms the space heats in just 10 minutes. Slow cooldowns equal the best of both worlds 

Usage patterns 

Better suited for pre-scheduled heating 

Suitable for both ad-hoc and pre-scheduled heating 

Room suitability 

Suitable for most room types, particularly larger spaces 

Best suited for small to mid-sized rooms; not suitable for bathrooms 

Heat distribution 

70:30 split of convection and radiation. Design helps to ensure successful circulation of fluid and encourage convection cycle 

50:50 split of convection and radiation – heats both the air and you directly for warmth on a deeper level 

Which is best for your home?

If you’re looking for steady, all-day heating for a main living space, oil filled radiators might just fit the bill. However, if on-demand heating is a priority, ceramic radiators stand out thanks to their rapid heat-up times. Both are 100% efficient at point of use and feature precision thermostats that better regulate room temperature. However, oil filled radiators may be less cost-effective if used for sporadic heating. As they need time for the oil to spread throughout the entire unit, this could potentially lead to higher energy consumption if you crank up the thermostat expecting instant warmth.

Aesthetics & design

Ceramic radiators are known for their compact and uniform designs; perfect if you prefer a minimalist aesthetic. On the flip side, oil filled radiators provide more design flexibility. With the choice of horizontal, vertical, modern or traditional finishes, you’re guaranteed to find something that matches your home’s design scheme. Oil filled radiators are often considered the luxury choice – these radiators take advantage of their striking looks to add a touch of designer chic to your space.

Which is best for your home?

If you're in search of a space-saving, compact, and minimalist heater, ceramic radiators could be the perfect fit for your space. If design is a top priority, oil filled radiators are meticulously crafted to not only perform well but also enhance the visual appeal. With a variety of shapes, sizes, and finishes, these radiators cater to every preference. So, if you're looking for a heater that's both a showstopper and highly functional, go for oil filled.

Installation & maintenance

Installation is swift and straightforward, as is the case for all electric radiators. With no risk of carbon monoxide, you don’t have to worry about annual servicing either! Whatever your preference, you're guaranteed a cost-effective and low-maintenance heating system.

If you’re looking for a permanent wall-mounted heater, a hardwired oil filled radiator offers a completely integrated appliance with a tidier finish to boot. If you’d prefer the freedom of moving your heater from spot-to-spot, ceramic radiators can be DIY-installed on the wall or made freestanding. Either way, they’re both low maintenance with similar warranties.


Efficient programming capabilities are a key aspect of modern electric radiators. Both oil filled and ceramic radiators come equipped with advanced energy-saving features to enhance your heating experience and make things as convenient as possible.
