Course Overview

Bacterial growth in domestic hot water (DHW) systems presents a critical safety and compliance challenge for modern facility management and mechanical design. In this concise mini-training module from Caleffi North America, industry professionals will explore actionable strategies to control water temperatures, prevent Legionella proliferation, and deliver safe, code-compliant potable water.

What You’ll Learn

• Legionella Growth Factors: Identify the precise temperature windows and mechanical system conditions that allow waterborne pathogens to thrive, and how to eliminate them.

• Thermal Disinfection Protocols: Master the techniques for elevating system distribution temperatures to neutralize bacteria while balancing precise downstream scald protection.

• Recirculation & Balancing: Learn how to maintain uniform thermal levels across the entire piping network, eradicating stagnant, lukewarm dead legs where bacteria multiply.

• Proactive Mitigation Best Practices: Apply proven design, installation, and maintenance standards to ensure long-term health, safety, and regulatory compliance.
