Passive Houses: The Key Role of Inertia Radiators in RE2020

In this article, we explore how inertia radiators are emerging as an essential asset for meeting RE2020 standards and achieving optimal thermal comfort in a passive house.

With the rollout of the RE2020 environmental regulation, home design is shifting toward more energy-efficient buildings — even passive houses. But what role does the inertia radiator play in this transition?

RE2020: What Is It?

In effect since January 2022, the RE2020 regulation sets strict standards for energy consumption and thermal comfort. New homes must not only limit their primary energy use, but also optimize their ability to produce and retain heat. This is where inertia radiators stand out for their performance.

Why Is the Inertia Radiator an Ally of the Passive House?

Unlike traditional radiators, inertia radiators are designed to store heat and release it gradually, even after switching off. Equipped with a heating core (in cast iron, ceramic, or stone), they diffuse soft, even warmth that helps reduce consumption peaks.

Within the RE2020 framework, these appliances contribute to lowering heating demand while ensuring optimal comfort. They maintain a stable temperature without excessive electricity use, making them a natural fit for passive-house logic.

Fogo’s Strategy: Innovative Inertia Radiators

At Fogo, we have chosen to combine inertia with intelligence. Our inertia radiators integrate connected control systems that adapt heating to user habits and outdoor climate variations. The result: consistent thermal comfort, reduced consumption, and seamless integration into projects that comply with RE2020.
