Type 21 Double Panel Radiators

Knowing what type of radiator a room has or needs is vitally important in helping ensure the space is heated effectively. Many people will know the style of radiator they currently have (cast iron, aluminium etc.) but not many people know what type of radiator they have.

If you have a convector radiator, you’ll need to know what type of radiator it is. In many homes across the UK, we have Type 21 radiators helping keep us warm. If you’re about to buy a new radiator, you’ll need to know whether you need a Type 21 model. Trade Radiators can help you choose the correct radiator for any space.

When Should You Choose a Type 21 Radiator?

It helps to know what exactly this type of radiator this is.

A Type 21 (commonly pronounced “two-one”) is a two-panel radiator with one set of fins in the middle. The fins are what takes the heat generated and radiate that heat around the room.

Type 21 radiators will usually have a depth between 70mm and 100mm.

If your radiator only has one panel and one set of fins, you currently have a Type 11 radiator. If it is double panel but has two sets of fins (i.e. looks like teeth), you have a Type 22 radiator.

How Does a Type 21 Radiator Work?

When a convector radiator is on, the radiator works to heat the fins you see in the middle as you look straight down. The fins will heat cold air passing through the radiator as it rises and circulates back out at the top.
