10 Best Oil Filled Heater 2025 in the UK

The Russell Hobbs 650W Oil Filled Radiator is designed for small rooms up to about 10 square meters, making it a good fit for bedrooms or small living spaces. Its 650-watt heating power provides gentle, even warmth through 5 fins that help spread heat efficiently. You can adjust the thermostat to control the temperature, which helps maintain comfort without wasting energy.

Safety is well considered here, with overheat protection and tip-over cut-off features that give peace of mind. The heater is quite portable, weighing just 2.8 kg and including carry handles and castors for easy movement. It’s also relatively quiet, typical of oil-filled radiators, so it won’t disturb you while running.

The 650W power limits how quickly or how much area it can heat compared to larger models, so it’s not suitable for bigger rooms or very cold conditions. The physical size is compact but might still take up some floor space given its pedestal design. This radiator is a solid, safe, and energy-conscious choice if you need a heater for smaller rooms and value portability and quiet operation.

The Pro Breeze Oil Filled Radiator is a powerful 2500W heater featuring 11 fins that ensure efficient and quick heating, making it suitable for various indoor spaces like living rooms, offices, and bedrooms. It offers flexibility with three heat settings (1000W, 1500W, and 2500W) and an adjustable thermostat, allowing users to personalize their warmth. The built-in 24-hour timer enhances energy efficiency by running the heater only when needed.

Safety is a priority with this heater, as it includes overheat protection, a tip-over switch, and automatic thermal shutoff, making it a safe choice for homes with children or for use in bathrooms. Its slim design and portability, aided by four wheels and a carry handle, make it easy to move and store. Additionally, it helps save on energy bills by allowing targeted heating rather than heating the entire home.

However, it weighs 8.3 kg, which might be cumbersome for some users to move frequently. Noise levels are low, ensuring a quiet operation, which is beneficial for bedrooms and offices. The energy efficiency is good, but oil-filled radiators generally take longer to heat up compared to fan heaters. The heater's white color and pedestal form factor blend easily into most home decors. This product is highly rated with a 4.3 out of 5 stars from nearly 4,000 customer reviews, indicating general satisfaction among users. It is best suited for individuals looking for a safe, portable, and efficient heating solution for specific rooms rather than entire homes.

The De'Longhi Dragon 4 TRD41025T Oil Filled Radiator is a suitable option for those seeking effective indoor heating with a focus on ease of use and reliability. With a maximum heat output of 2.5 kW and three heat settings, it offers flexibility to manage warmth based on personal preference and room requirements. The enhanced chimney effect design is a standout feature that ensures efficient heating by speeding up hot air distribution. This is particularly beneficial for those in need of quick and consistent warmth during colder months.

The heater's portability is another plus, thanks to its pre-assembled easy wheels and carry handle, allowing for hassle-free movement across different rooms. Its elegant white design would fit nicely in most home decors, adding an aesthetic appeal beyond functionality. A 10-year manufacturer's warranty underscores its durability, securing long-term use.

Potential buyers should consider its size and weight—at 17.52 kg and dimensions of 51.9 x 16 x 64.99 cm, it may not be the best fit for smaller spaces or for those who require frequent repositioning of the heater. While the medium (1,400 Watt) and minimum (1,100 Watt) settings provide options for energy efficiency, it might still consume more electricity at maximum power compared to some alternative models. Noise levels are generally minimal with oil-filled heaters, offering a quieter heating solution compared to fan-based units. This radiator is well-suited for providing lasting warmth in larger rooms or spaces where its size can be accommodated without issue.
