Convector Type
Single Convector
Double Convector
Central heating radiators come in a wide variety of types including Type 11, Type 21 and Type 22. Depending on whether you require a high heat output (BTU) or a slimline radiator for small rooms and compact spaces; the Type which you choose can be quite an important factor.
A single central heating radiator has one row of fins (convectors) making it slimmer and ideal for smaller spaces. Type 11 radiators, also known as a single panel single convector radiator, has one panel covering a single row of fins. The back of the radiator, which is closest to the wall, is open. Type 21, also known as a double panel double convector radiator has one row of convectors sandwiched between two panels.
A double convector radiator has two rows of fins and is encased between two panels. Type 22 radiators, also known as a double panel double convector radiator, have a slightly larger depth and typically produce more heat. This makes them ideal for larger bathrooms, kitchens and other living spaces.
