Low On Energy, Large On Output

Available as a K3 model, the Stelrad Compact K3 Radiator is built with 3 radiator panels and 3 convection fins. As the demand for renewable energy increases, we at Stelrad like to remain ahead of the game. Higher capacity radiators, such as the Stelrad Compact K3 Radiator, are some of the most energy efficient radiators with a smaller carbon footprint, meaning a powerful heat dispersing system, with less of an environmental impact. Enjoy guilt free warmth from Stelrad.

Possessing three sets of panels and three sets of fins ensures that additional heat is emitted, without taking up too much space in your home. The Stelrad Compact K3 Radiator is only slightly larger than any of our K2 models, making it a suitable choice for low energy systems, while providing the highest possible heat output. Size options available range from heights of 300mm – 700mm and lengths of 400 – 2400mm, meaning you can conserve space, enjoy your home with the layout you decide, while remaining warm all year long. If you need help deciding what size Compact K3 Radiator is most suitable for your household, we are here to assist.
