Stelrad

Benefits

Horizontal decorative radiator with a flat front

The Planar ECO radiator unites design with our serial flow technology (water flows first through the front panel) and is perfectly suited for heating systems that work with low operating temperatures. This ECO technology results in high energy efficiency, maximum radiation, faster heating rate and less waste of energy. The combination of this technology with the flat front, a design upper grille and side panels allows you to enjoy our green heat technology with style and luxury.
