Covers a massive expanse of wall with a single unit, distributing heat evenly across long living rooms, dining spaces, or hallways.
The bright white gloss powder coat is easy to clean, highly durable, and seamlessly matches existing white window frames and internal decor.
The double-panel design provides rapid heat-up times and sustained warmth, easily heating medium to large living spaces as a primary heat source.
