As radiator covers come in many designs and materials, it can be hard to know which one is best. But when it comes to efficiency, it’s widely accepted that metal is the most efficient radiator cover in terms of heat loss. However, these can also be incredibly dangerous, as they conduct the heat and can be incredibly hot to touch.
That’s why the most common type of radiator you can buy is a wooden radiator cover. While this material isn’t the best conductor, it’s considered to be the best in terms of safety and aesthetics.
It’s important to understand that you cannot use a radiator cover if you have a storage heater, however. Their high heat output makes them a fire hazard.
