Type 22 Radiators
With two sets of fins, and both front and back panels, the Type 22 convector radiator gives the highest heat output of the three sizes. It’s also the widest size, usually being around 30mm wider than a Type 21, and is most suited to larger rooms with more space to heat. This size might look bulky or clunky in a small room, but on larger walls you’ll rarely notice the difference. If depth is a concern, consider a Type 21 radiator but in a slightly longer or higher size to match the heat output.
