7 Best Delonghi Oil Heaters 2025 in the UK

The De'Longhi Dragon 4 TRD41025T Oil Filled Radiator is a noteworthy choice for those needing an effective heating solution for indoor spaces. It features a powerful 2.5 kW heat output with three adjustable settings, allowing for flexible temperature management to suit varying comfort needs. The enhanced chimney effect is a clever design choice, accelerating the dispersion of hot air, which means your space heats up more efficiently. This is particularly useful for medium-sized rooms where quick heating is appreciated.

A standout feature of this radiator is its ease of mobility. It comes pre-assembled with easy wheels and a carry handle, making it user-friendly for moving between rooms. Its elegant, white pedestal design fits well into most home decors, adding a touch of style rather than being an eyesore.

Safety is always a prime concern with any heating device, and De'Longhi has a reputable track record in this area. Additionally, it operates quietly, which is an advantage for those who prioritize noise control in their home or office environment. Despite its excellent build, at 17.52 kg, it may still pose a challenge for some when moving frequently. Lastly, a 10-year warranty underscores its durability, which might imply higher upfront costs compared to other models.

The De'Longhi Radia S Oil Filled Radiator offers a potent heating power of 2000W, making it suitable for rooms up to 60m3. Its long-lasting heat retention is a significant plus, as the heated oil continues to release warmth even after the unit is turned off. The Real Energy Technology enhances efficiency by steadily increasing the temperature, resulting in quicker and more cost-effective heating. The Eco Plus function further optimizes energy consumption by adjusting to the room’s temperature automatically, which is great for saving on energy bills.

Users will appreciate the digital LED interface that allows for easy control over the temperature, power settings, and timer, adding a level of convenience and customization. Safety is also well considered with the safety thermostat and anti-frost functions, ensuring reliable operation even in colder conditions. Portability is another strong point; the radiator comes with a handle and pre-assembled castors, making it effortless to move between rooms without any assembly required.

At 10.6 kg, it's relatively easy to handle for a device of its kind. However, the unit's size (20 x 35 x 60 cm) may be bulky for smaller spaces, and its corded electric power source limits placement options to areas near electrical outlets. Additionally, while it’s generally quiet, any oil-filled radiator may produce slight noise, which could be a minor drawback for some users.

The De'Longhi TRDX41025E Oil Filled Radiator, Dragon 4 Pro, is a reliable indoor heating option with a strong heating power of up to 2500 watts and three adjustable heat settings. The digital control panel with an LED display and a 24-hour timer offers easy and precise thermostat control, allowing you to set the preferred temperature and schedule heating times conveniently.

The exclusive ECO function is a notable energy-saving feature, helping you to reduce electricity consumption while maintaining comfort levels. Additionally, the anti-frost protection is beneficial in preventing freezing in colder conditions, making it a practical choice for colder climates. Safety is well-addressed with this unit, featuring anti-frost protection and sturdy, pre-assembled rubberized wheels that enhance portability across different floor types.

With a noise level that is generally low for oil heaters, it ensures a quiet operation, ideal for home use without causing disturbances. However, the heater's weight of 1.9 kg might pose some difficulty in moving it around frequently. The relatively high price and the need for floor space (floor mount plug profile) could be potential drawbacks for those with limited space or budget constraints. These minor issues aside, the De'Longhi TRDX41025E is a solid choice for efficient and controlled heating.
