Tubular Designer Radiator Quantum 405×1600 mm — Black

Designer tubular designer radiator BQ Quantum in the 405×1600 mm format (Black) is made for interiors where heating should look sharp, minimal, and intentionally architectural. Produced by a well-known Hungarian manufacturer, the model is built from square-profile tubes that create a strict, graphic rhythm on the wall. The black finish highlights the geometry and turns the radiator into a confident, modern accent—without visual clutter.

This size is often chosen when you want a low, elongated heating line that supports the space rather than dominating it.

Design logic of the Quantum series

• Square-profile tubes — strict lines and a clean, premium look
• 405×1600 format — a long horizontal “heat band” along the wall
• Black finish — deep contrast that works with modern interiors
• Tubular structure — visually lighter than bulky panel models

How tubular heating works

Tubular radiators are valued for the way they support more even air movement in the room. The spacing and construction allow warm air to 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” designs.

Materials and operation

BQ Quantum is made from steel and engineered for stable performance in water-based heating systems. The protective coating is designed to handle temperature load and everyday humidity, helping the radiator maintain its appearance over time. Official warranty — 5 years.
