TYPE 21 RADIATORS FAQs

What is the Difference Between Type 21 and 22 Radiators?

As explained above, a Type 21 radiator is a double panel radiator with a front and rear panel and one row of convector fins. A Type 22 radiator also has double panels but it has two rows of convector fins.

Because Type 22 has two rows of convector fins, it has an increased surface area. It will, therefore, product more heat. This is beneficial for larger rooms. However, this extra row of fins also means that the Type 22 is thicker than a Type 21 radiator so will protrude further from the wall. If you are short on space, or simply prefer a more streamlined appearance, a Type 21 radiator will be better choice for you.

Room layout also impacts whether to choose a Type 21 or Type 22. Under a window, where a full width Type 22 will provide too much heat and a shorter one would look odd, a full width Type 21 radiator may be perfect for the job.

How Do I Clean a Type 21 Radiator?

It is important to clean your Type 21 Radiator, not only for appearance, but to keep your energy bills down. Dust caught between the convector fins of a Type 21 radiator can trap heat and force the radiator to work harder.

Turn off your central heating before cleaning the radiator. This will stop the convection process from drawing more dust into the radiator as you clean.

Use your hoover to remove most of the dust. Place an old towel under the radiator and use either a radiator brush or a home-made cleaning stick to push out the dust from between the convector fins. You can also use a hairdryer to blow the dust down onto the towel.

Use mild soapy water and a cloth to wipe over the front panel. Be sure to dry it thoroughly after.

What is a Type 21 Radiator?

A type 21 radiator is a double panel convector radiator with a front panel, a back panel, and a single row of convector fins. The convection fins are the metal zig zag structure that you will see between the front and rear panels.

As the hot water heats up the panels, the convector fins heat up too. The fins add to the heated surface area, creating more heat while also helping distribute the heat more evenly into your room.

Other Type 21 features to look out for are whether or not is has a top grille and if it is made from steel or another material. All Stelrad’s Type 21 radiators are stainless steel for strength, excellent heat conductivity and, of course, rust-free longevity.

 

Choosing Your Type 21 Radiator

As Stelrad offer the widest range of radiator styles and sizes in the UK, we have a superb choice of high-quality Type 21 radiators for you to explore today.

The Vita Compact is a traditional range of Type 21 radiators with the distinctive grooved front we are all familiar with, and a strong steel build, for classic, reliable heating.

With a curved top grille and end sides, the Softline Compact range offers a more streamlined option and, with 16 sizes to choose from, you are sure to find the best Type 21 radiator for your room.

When viewing Stelrad’s radiators, be aware that we call a Type 21 radiator a P+ radiator. In your search results, you can filter by type using the filter menu. On each individual radiator page, you will have a drop down from which you can select the construction. For a Type 21 model, you will need to select P+.

We recommend that you use our helpful radiator shopping tools to assist you in choosing the best radiator for your room and requirements. Once you have measured your wall space, use our Radiator Size Calculator to see a range of radiators which are suitable for the wall space you have.

However, same size radiators can produce different levels of heat. So, to ensure you get the best heat performance from your radiator and for your room, use our Heat Loss Calculator. This will take into account not only the size of your room, but its construction and window space too.
