NUPI Industrie Italiane installed its ELOWEB radiant heating system in a residential building in Busto Arsizio, where a single-family home is undergoing an energy retrofit that combines comfort, efficiency, and design. For a surface area of ​​140 m², the Eloweb radiant system was chosen as the heart of the underfloor heating system, designed to operate in heating-only mode. The system solution adopted includes a 10 cm installation spacing, ideal for ensuring uniform heat throughout the room, and a 30+22 mm Eloweb Strong thermoformed panel for stable, durable, and high-performance installation. This project confirms the adaptability of Eloweb technology even in renovation contexts, where product quality and meticulous design allow for an improved living environment, improving thermal comfort and reducing consumption. This is another concrete example of how system retrofitting can provide real added value to everyday living.
