Rinnai will use Installer Show 2025 to spotlight the often-overlooked threat of limescale in hot water systems—and why scale protection is essential for long-term system performance, efficiency, and cost control. With hard water affecting over 60% of UK sites, Rinnai is urging installers to prioritise scale defence as a standard part of every domestic hot water (DHW) installation.

Visitors to the Rinnai stand will be able to explore the science behind scale formation and see how solutions like Aquabion—an advanced galvanic and electrolytic system—transform calcite into non-adhering aragonite, preventing build-up and protecting system integrity.

But this isn’t just about showcasing a product. It’s about starting a conversation. Rinnai’s technical team will be on hand to discuss real-world installation scenarios, share best practices, and help installers understand how scale protection can reduce callouts, extend appliance life, and improve customer satisfaction. Come to the Rinnai stand and get involved and join the conversation on scale protection and system longevity.
