With this super-efficient and space-saving, Type 21 Double Panel Plus convector radiator from Stelrad, you can enjoy tremendous warmth in your home, without losing out on valuable wall-space.

This radiator measures 600mm x 600mm, with a depth of 77mm and a wall projection of 112mm. This allows the radiator to be installed in the smallest areas of your home which cannot accommodate a large radiator. This includes the en-suite bathroom, downstairs cloakroom, hallway or box-bedroom.

Stylish as well as conveniently sized, this radiator has a front panel with contouring detail, integrated top grille for a more refined overall look and a white powder coat finish. The latter ensures that this versatile heating choice can be placed in rooms of any style and colour scheme from neutral to bright.

This radiator has a heat output of 3871 BTUs an hour, which will efficiently heat any room to a comfortable and inviting temperature. Its convectors are precision welded to the waterways, to ensure optimum performance with every use.

Made from mild steel and with a powder coat finish, this is a resilient model which is designed to last. As with all Stelrad products, it can be relied upon to provide you with years of great use.

Stelrad provide a 10 year guarantee with this radiator.

Please note: this radiator does not come with valves.
