What are oil-filled radiators?

If you’re new to oil-filled electric radiators, you might be wondering exactly what they are and how they work. These heaters are defined by their thermodynamic fluid, which flows throughout the body of each appliance and offers superior heat retentive capabilities. They supply lasting warmth with slow cooldown times, even after the radiator has stopped drawing power from the wall, promoting maximum efficiency. The element is fully submerged in this fluid so that when it heats up, it warms the surrounding liquid, quickly heating the body of the radiator.

Our range of oil-filled heaters are typified by their stylish, contemporary appearances and advanced controls, offering the very latest in modern technology. Crafted from the ground up, they provide quality electric heating that’s both reliable and efficient.
