Variations of Central Heating Radiators
Generally central heating radiators are installed in your home or workspace to keep it warm and cosy. There are many different designs and styles of radiators available to the consumer in all different sizes and colours available to fit any type of home decor.
Radiators not only vary in size but they also vary in their heat output. It is very important to choose the right radiator for the right job or room so you need to make sure you choose the correct one to fit all your needs.
There are three different types of radiator for different functions;
The k1 or type 11 radiator is a single panel single convector that normally consists of one steel panel on the front and it usually has one convector otherwise known as a fin. In order to heat a room to a decent temperature level you have to have a central heating radiator with sufficient capacity to do the job efficiently so it is more cost-effective. To make sure you get it right you can calculate the expected heat loss so you know the right size of radiator to buy.
P+ or type 21 radiators are also known as double panel single convectors. These radiators have two steel panels at the front and rear and usually consist of one fin or convector. Once again you need to make sure that you purchase a radiator that has good capacity, is efficient, and satisfies the heat loss calculation for the room in question.
Double panel double convective radiators are known as K2 or type 22 radiators. They generally have two steel panels to the front and rear and two convectors. A great example of one of these types of radiator is the Myson premier round top radiator.

Higher Btu measurements are often reflected in higher prices but all difference styles will be available no matter what the BTU is. Whether you are looking at aluminium, cast iron or chrome radiators, always check the BTU and make sure they are the right radiator for the size of room they will be heating.
