Designer horizontal radiator BQ Quantum in the 405×1000 mm format (Black) is created for interiors where heating should look like a deliberate design element—strict, minimal, and visually “clean.” Made by a well-known Hungarian manufacturer, the model uses square-profile tubes arranged in a precise rhythm, giving the radiator a strong architectural character while keeping it compact along the wall.
This size is a practical choice for modern apartments, studios, and commercial spaces where you need confident heat output in a low, elongated format.
Design logic of the Quantum series
- Square-profile tubes — strict geometry and a premium look
- 405×1000 format — compact horizontal line on the wall
- Black finish — deep contrast for loft/minimal interiors
- Tubular structure — visually lighter than bulky panels
How tubular heating works
Tubular radiators are valued for supporting more even air circulation in the room. Thanks to the tube spacing and construction, warm air can pass through the radiator body more freely, helping distribute heat across the usable area (depending on heat output and system configuration).
Because airflow through the structure is less restricted, the room can reach a comfortable temperature faster compared to more “closed” radiator designs.
Materials and operation
BQ Quantum is made from steel and engineered for stable performance in water-based heating systems. The protective coating is resistant to temperature load and everyday humidity, helping the radiator maintain its appearance over time. Official warranty — 5 years.
