Product Information

Stelrad Compact K1 Single Panel Radiator 700 x 400mm

The Stelrad Compact K1 Single Panel Radiator 700 x 400mm is a practical and reliable heating solution for homes and other spaces where wall space is limited. Part of Stelrad's popular Compact range, it combines dependable heating performance with a neat, compact design that can suit a wide variety of interiors and applications. Its horizontal layout makes it easy to position on the wall, while the integrated top grille and side panels create a clean, professional appearance. These components are designed to minimise movement and provide a secure fit, helping the radiator maintain its smart appearance once installed.

Efficient Heating Performance

This Type 11 (K1) radiator features a single panel and single convector, providing effective heat distribution in a slim and practical format. The radiator is manufactured from durable steel and finished with a smooth powder-coated Traffic White coating, making it easy to coordinate with a range of interior styles. With a heat output of 1,526 BTU/h, the 700 x 400mm radiator is well suited to applications where a compact radiator with a moderate heat output is required. Its 700mm height and 400mm width provide a useful balance between heating performance and available wall space.

Quality and Durability

The Stelrad Compact K1 is manufactured to recognised quality standards and meets BS EN 442 requirements. It is designed for a maximum working pressure of 10 bar (145 psi), making it suitable for central water heating systems. The radiator is supplied with wall-mounted fixings and features a 1/2 inch BSP pipe inlet size. BIM information is also available, making it a useful option for projects where Building Information Modelling data is required. A 10-year warranty provides additional reassurance about its long-term reliability.

Delivery

Every order is personally reviewed by our experienced team to ensure everything is correct before dispatch. We offer delivery from as little as the next working day on selected products, so please refer to the dark blue Estimated Delivery box above for the expected delivery timeframe for this item.

We work with trusted manufacturers and specialist delivery partners to ensure your order arrives safely and on time. You'll receive tracking details once your order has been dispatched, and if we need to confirm any delivery details, one of our team will contact you directly to keep everything running smoothly.

Roof Tiles & Fittings:

We recommend ordering an additional 10% of roof tiles to allow for any breakages that may occur during delivery or handling. Roof tiles are naturally fragile, and having a few extra on site helps prevent delays and ensures your roofing project can be completed without interruption.
