10 Best oil radiator heater 2025 in the UK

The Pro Breeze Oil Filled Radiator offers a powerful heating solution with its 2500W capacity and 11 fins, making it effective for sustained warmth in spaces like homes and offices. The adjustable thermostat with three heat settings (2500W, 1500W, and 1000W) allows users to customize their heating needs, while a 24-hour timer boosts energy efficiency by letting you select specific hours for operation.

In terms of safety, this unit includes essential features such as heat protection, a tip-over switch, and automatic thermal shut-off, ensuring peace of mind in environments like nurseries or children's rooms. Its portability is enhanced by four easy-roll wheels and a carry handle, making it convenient for moving and storing, although at 11.9 kg, it might be a bit heavy for some.

The slim design helps it fit into tight spaces, and the black finish adds a touch of modern aesthetics. While the radiator is energy efficient, heating only the required space and potentially reducing energy bills, it's important to note that it's designed for indoor use only. It's particularly well-suited for home offices, kitchens, and bedrooms, providing targeted warmth without needing to heat the entire home. The Pro Breeze brand is recognized for its heating products, suggesting reliability and quality backed by positive customer reviews. Considering its features, it combines functional heating with safety and efficiency, making it a solid choice for those looking for a dependable oil radiator heater.

The De'Longhi Dragon 4 TRD41025T Oil Filled Radiator offers an effective heating option with its enhanced chimney effect that accelerates hot air through vents, which is great for distributing heat efficiently in indoor spaces. With a robust 2.5 kW heat output and three adjustable heat settings, it gives users flexibility to choose their preferred intensity level.

The heater is designed for easy maneuverability, featuring pre-assembled wheels and a carry handle, making it convenient to reposition within your home. Its elegant, pure white finish ensures that it complements most interior decors. Safety features are well-considered, with a 10-year manufacturer's warranty adding assurance of long-term reliability. Quiet operation is another advantage, making it suitable for use in bedrooms or living rooms where noise might be a concern.

However, it might not be the most energy-efficient choice due to its high wattage, which could result in higher electricity bills if used extensively. In terms of size, this pedestal-style heater is quite hefty, measuring 51.9 x 16 x 64.99 cm and weighing 17.52 kg, which might be cumbersome for some users despite the wheels and handle. While it ranks well in its category, users should consider their specific heating needs and space constraints. The De'Longhi Dragon 4 is an excellent option for those who prioritize effective heating, safety, and aesthetics, but those seeking a more compact, ultra-energy-efficient heater may want to explore other models.

The Russell Hobbs 650W Oil Filled Radiator is designed to efficiently heat small rooms up to around 10 square meters, making it a good fit for bedrooms or compact living spaces. Its 5 fins help spread warmth evenly, and the 650-watt power strikes a balance between performance and energy use, so it won’t cause a big increase in your electricity bill. The adjustable thermostat gives you control over the temperature, allowing for comfortable and consistent warmth. Portability is a plus here — with built-in carry handles and castors, it's easy to move the heater from room to room.

Safety features include overheat protection and tip-over cut-off, which provide peace of mind when using it around children or pets. The noise level is naturally low since it’s oil-filled, so it won’t disturb your daily activities or sleep. In terms of design, its compact size and black color make it unobtrusive and easy to fit in various room styles, though the look is fairly basic and functional rather than stylish. The 2-year guarantee (with registration) adds reassurance about its durability.

On the downside, the 650W output means it’s not ideal for larger rooms or very cold spaces, and its heating speed might be slower compared to higher wattage models. This radiator is well-suited for those needing a quiet, portable, and safe heater for small areas without requiring advanced features or high power.
