ProRad radiators come in three designs: Type 11 (K1), Type 21 (P), and Type 22 (K2). Type 11 radiators are slimline single panel designs, ideal for small spaces. Type 21 radiators have a single convector (row of fins) enclosed by a second panel, making them efficient and slim. Type 22 radiators feature two panels and fins, offering higher BTU heat outputs but are larger in size. Each design serves different space and heating needs, from compact areas to larger rooms that require more heat. Slim profiles make Type 11 and Type 21 suitable for tight spaces, while Type 22 is perfect for higher heat requirements..
