Compact radiators — also known as convector radiators — are the most commonly fitted central heating radiators in UK homes. Their clean, panel-and-fin design with factory-fitted top grilles gives a neat, streamlined look while delivering reliable, efficient heat output. At PlumbXtra we stock Type 11 (K1), Type 21 (P+) and Type 22 (K2) compact radiators at trade prices, open to every customer, with free express delivery on orders over £500 to UK mainland addresses.

Choosing the right type is straightforward: a Type 11 single panel radiator is the slimmest option, ideal for hallways, small bedrooms and rooms with limited wall depth. A Type 21 double panel single convector gives a step up in heat output while keeping a relatively slim profile — perfect for medium-sized living rooms and kitchens. A Type 22 double panel double convector is the most powerful of the three, delivering maximum BTU output for larger rooms, open-plan spaces and properties with higher heat loss. All our compact radiators are pressure tested, certified to BS EN 442 and backed by a 10-year manufacturer warranty. Not sure which type is right for your room?
