Water quality, a lever for the energy performance of heating systems

Did you know that 1 mm of scale in the boiler means 7% less heat transfer? At a time when energy savings are more relevant than ever, this article is an opportunity to highlight some good practices related to water quality in heating networks, both in terms of design and installation and operation. In the case of closed circuits, especially heating, no regulation sets a clear framework. However, water quality is paramount to ensure a good energy performance of the heating system. This article outlines the risks related to water and the best practices to adopt to ensure longevity, comfort and energy performance in a heating installation.
