Type 21 Radiators

Shop our type 21 radiators. These efficient and understated double panel single convector radiators offer a simple heating solution for almost any room in your home. Like the look of a slimline double radiator but need something a little more compact? Try our range of single panel radiators. Free standard UK delivery on orders over £499.

Sometimes known as double panel plus radiators, type 21 radiators are classed as single convector radiators due to the fact that they are composed of a single row of fins between two panels. This makes them a relatively compact and small double radiator option when compared to double panel radiators (known as type 22).

Each and every one of our type 21 radiators has been handpicked for its quality. Made by using modern manufacturing techniques and fine materials - such as stainless steel - you can rest assured your new radiator will provide years of faultless use. The overwhelming majority of double panel single convector radiators even come with lengthy guarantees against defects. Browse our full range of convector radiators.
