What is Type 22 radiator?
A type 22 radiator is a radiator with 2 panels and 2 layers of fins. More fins inside means there’s more space required to store them. A Type 22 radiator is therefore generally wider than a Type 21 radiator.
What’s the difference between Type 11 and Type 22 radiator?
Type 11 Radiator Sometimes called a K1 type, this design gives out the lowest heat, but is also much thinner than type 21 and type 22 radiators, so is perfectly suited to rooms where space is a premium.
What is a Type 22 central heating radiator?
A double panel convector radiator (also known as a Type 22) is an even more efficient and effective way of heating a room because it features two panels and two sets of convector fins, so the surface area of the radiator is vastly increased.
What is a Type 22 double panel radiator?
Also known as ‘double panel, double convector’ , ‘double, double’ or ‘K2’ radiators, Type 22 convector radiators have the front and back panel, plus two sets of convector fins running down the centre of the rad.
What is the difference between Type 21 and Type 22 radiators?
Type 22 radiators are thicker than Type 21. The reason for this is that they have two sets of convector fins, thus taking up an inch or so more in diameter. This makes them better suited to larger spaces that need more power to be heated.
What is a Type 20 radiator?
Steel panel radiators of type 20 Compact with side connection are hygienic. This means that the radiators consist only of heating panels. Their construction is not complicated by additional convective panels and protective elements.
How do I know what type of radiator I have?
Another clue is to look at the radiators. If each radiator has only one pipe connected to it, you have a one-pipe steam system, the most common type of steam heat. If your radiators have two pipes, you might have two-pipe steam or a hot-water system. To determine which one, check the boiler.
Can I replace a Type 21 radiator with a Type 22?
There are no rules that say a type 22 radiator can’t be used anywhere. However, if a type 21 radiator (in any room) gives the correct output and to a length and height suitable looking for the wall space, then you use it. It will not come as far out from wall as a type 22.
What is a Type 21 plus radiator?
Type 21 radiators are also known as P+ radiators or double panel plus radiators. They are a conventional type of radiator with 2 panels (front and back) and 1 set of convector fins in the middle usually zigzag shaped which distribute air evenly.
What type of radiator gives out most heat?
Aluminium radiators
Aluminium radiators provide the highest potential BTU output possible. That doesn’t mean that every aluminium radiator has a higher heat output than every steel radiator, for example. But aluminium radiators have the greatest heat output potential of any type.
What is a Type 22 double panel convector radiator?
A popular heating option for decades, these reliable and efficient radiators continue to sell in droves, and a Type 22 double panel convector radiator offers even greater heat output for your home.
What is the difference between Type 21 and Type 22 radiator?
This row of fins heats the body of air within the radiator and allows it to escape through vents, usually found at the top of the radiator itself. The main difference between Type 21 and Type 22 radiators is the layers of fins, also known as the number of convectors.
What does “22” mean on a radiator?
The “22” in the name refers to the number of panels and rows of fins, i.e. the radiator has two panels and two sets of fins. If you walk over to your convector radiator and look right down the middle, you’ll see the connecting fins in the middle. These fins are what take the energy generated in the panels and help heat a space.
What are the different types of radiators?
There are other types of convector radiators around which are less common than Type 21 and 22, these are Type 11 (also referred to as K1) and Type 33 radiators. Type 11 is a single panel radiator with a single layer of fins.
