Designer tubular designer radiator Praktikum in the 425×1200 mm format (White) is a next-generation decorative heating solution built around concise style and refined simplicity. The tubular geometry creates a calm, orderly rhythm, while the white finish keeps the radiator visually light—an easy match for classic interiors as well as restrained modern spaces. The model warms efficiently and supports a comfortable everyday microclimate.
This size is often chosen when you need balanced horizontal coverage without making the radiator a dominant wall element.
Design logic of the Praktikum series
- Long tubes with flat ends — a neat architectural rhythm
- 425×1200 format — practical horizontal coverage along the wall
- White finish — clean, neutral, and interior-friendly
- Tubular construction — practical form with easy surface access
How tubular heating works
Tubular radiators are valued not only for their look, but for how they distribute warmth. Tube spacing supports more even air movement through the radiator body, helping heat spread across the usable area of the room (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
Praktikum 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 preserve a neat exterior appearance over time. Official warranty — 5 years.
