10 Best Oil Filled Electric Radiators

The De'Longhi Dragon 4 TRDSX40820E.WB is a solid choice if you're looking for a quiet and efficient oil-filled radiator to heat a medium-sized room up to about 60 cubic meters. With a powerful 2000W output and three adjustable heat settings (900W, 1100W, 2000W), it offers flexibility to match your comfort needs while helping manage energy use thanks to its ECO Plus feature that adapts the heat based on room temperature. The electronic timer lets you schedule the heater to turn on or off within a 24-hour window, which adds convenience and can save energy. It includes a safety thermostat to prevent overheating, and its chimney-style design with larger fins helps spread warm air steadily and quickly around the room.

While the radiator is on the heavier side at over 15 kg, it comes with wheels and a compact footprint (about 55 cm wide) making it fairly easy to move around your home. It’s quiet in operation, ideal for living spaces where low noise is appreciated. One thing to consider is the size and weight if you expect to move it frequently between floors or rooms, as it's not the lightest option available. Also, while it’s great for indoor use, it’s not meant for outdoor areas. If you want reliable, lasting warmth with useful digital controls and safety features, this De'Longhi model covers those well without being complicated to use.

The De'Longhi Radia S is a solid choice if you need an oil-filled radiator for heating medium to larger rooms (up to about 60 cubic metres). Its 2000-watt power output means it can warm spaces efficiently without being too heavy on electricity. A key plus is the digital LED display, which makes it simple to set your preferred temperature, power level, and timer—helpful for managing heating times from half an hour up to 24 hours. The ECO and Anti-frost functions add convenience by automatically adjusting to keep the room comfortable while saving energy.

Portability is well handled with built-in handles and foldable castors, so moving it between rooms is hassle-free despite its 10.6 kg weight. Safety is covered with a thermostat to prevent overheating, giving peace of mind for use around children or pets. One minor drawback is that being oil-filled, it takes a bit of time to warm up initially compared to fan heaters, and it may not be the quietest option if you’re very sensitive to background noise, although most users find it reasonably silent.

The size is compact enough for typical home spaces without being bulky. If you want a reliable, energy-conscious heater with easy controls and safety features, the De'Longhi Radia S fits well, especially for those who want steady, lasting heat rather than quick bursts.

The Russell Hobbs 1500W Oil Filled Radiator is a solid choice for heating a medium-sized room up to about 15 square meters, such as a living room or double bedroom. It offers three heat settings—600W, 900W, and 1500W—which allow you to adjust the warmth to your comfort and save energy when full power isn't needed. The 7 fins help spread heat evenly, ensuring steady warming of your space.

This radiator includes an adjustable thermostat, enabling it to maintain your chosen temperature without constantly switching on and off, which provides greater control and comfort. Safety features include overheat protection and a tip-over switch that turns the heater off if it falls, adding peace of mind especially in homes with children or pets.

Portability is reasonable for this type of heater; it features carry handles and castors for moving it between rooms, despite weighing around 7.7 kg. The power cord is 1.45 meters long, a fairly standard length that may affect placement depending on outlet locations. While it does not have a built-in timer function, its quiet operation typical of oil-filled radiators makes it suitable for bedrooms or workspaces. The black finish and pedestal design are simple and unobtrusive, fitting most home decors. It comes with a 2-year guarantee (one year standard plus an additional year upon registration), providing decent after-sales support. For those seeking a reliable, easy-to-use heater for small to medium rooms, with strong safety features and flexible heat settings, this model is a practical option.
