Welcome to our extensive collection of Stelrad Novello ECO Radiators—the leading choice for energy-efficient, high-comfort heating.

Designed and engineered in Europe, this range combines a classic aesthetic with cutting-edge technology, making it perfectly suited for modern, low-temperature heating systems such as heat pumps and condensing boilers.

Key Technology: Novello ECO Series

The unique selling point is the patented Serial Flow Technology. Hot water is directed to the front panel first, maximizing the surface area that directly radiates heat into the room.

Up to 10.5% Energy Savings: Verified by Kiwa, the ECO technology reduces energy consumption by lowering the temperature of the rear panel, minimizing heat loss towards the wall.
Faster Warm-up: Provides up to 23% faster heat-up times compared to standard panel radiators.
Maximum Comfort: Delivers up to 53% higher average surface temperature on the front panel, enhancing the feeling of radiant warmth, even with lower system temperatures.

Comprehensive Customization for Every Room

This collection offers thousands of variations to match any room size and heating requirement:

Multiple Types: Choose from single-panel to triple-panel models (Type 11, 21, 22, and 33) to control depth and heat output.
Vast Dimensions: Available in six different heights (300 mm to 900 mm) and lengths spanning from 400 mm up to 3,000 mm.
Versatile Connections: Features an integrated preset valve insert and flexible connection options, including a convenient center connection, making installation easy and pipes simpler to pre-lay.
