Type 21 Radiators

If you need more warmth than a standard type 11 radiator but don’t have room for a large heating unit, a type 21 radiator is a great choice. Also called a double panel plus (P+) radiator, these convector radiators use two panels with a single set of fins sandwiched in between. This clever design boosts heat output while keeping the radiator slim enough to fit neatly against the wall, making them ideal for medium-sized bathrooms or hallways. They also come in a wide range of colours to match your decor, with horizontal and vertical options to help you make the most of your wall space. Shop type 21 radiators now.

FAQs

What is a type 21 radiator?

A type 21 radiator, also known as a double panel plus (or P+) radiator, has two panels and one set of convector fins. This helps them give off a more powerful heat output than a type 11 while being slimmer and more compact than a type 22. These radiators are a great middle-ground option for rooms that need extra heat without taking up too much space.

What is the difference between type 21 and type 22 radiators?

Although these two radiators have similar names, they work in different ways:

  • Type 21 radiator – These radiators have two panels but only one set of convector fins. They offer more heat than a type 11 radiator while staying relatively slim, making them a great choice for heating medium-sized rooms.
  • Type 22 radiator – These have two panels and two sets of convector fins, increasing the heat output significantly and making them ideal for larger rooms.
