Best practices at a glance

This section introduces a checklist of best practices that cover essential aspects of SIA 385/2:2025 compliance. These practices address hot water demand, thermal losses, auxiliary energy requirements, and other crucial elements, ensuring that installations meet the necessary standards and guidelines.

The practices

1. Assess and Calculate Hot Water Demand: Regularly evaluate the hot water demand based on actual usage patterns. This practice prevents under-sizing or over-sizing systems, which can lead to increased energy costs and inadequate supply. Refer to clauses regarding hot water demand in SIA 385/2:2025.

2. Optimize Thermal Losses in Storage Tanks: Implement insulation solutions to minimize thermal losses in storage tanks. Reducing these losses is critical for maintaining energy efficiency and complying with hygiene standards. This aligns with the thermal performance requirements outlined in SIA 385/2:2025.

3. Evaluate Auxiliary Energy Requirements: Assess and document auxiliary energy needs for heating water. Understanding these requirements helps in designing systems that support energy and water conservation, thus adhering to SIA 385/2:2025 certification standards.

4. Maintain Temperature in Distribution Pipes: Ensure that distribution pipes are kept at the required temperature to prevent heat loss and ensure comfort. This is crucial for meeting the energy efficiency and comfort requirements set by SIA 385/2:2025.

5. Minimize Thermal Losses in Draw-off Pipes: Regularly inspect and maintain draw-off pipes to minimize thermal losses. This practice enhances energy efficiency and reduces the risk of legionellosis, as highlighted in SIA 385/2:2025's guidelines.

6. Implement Heat Recovery Systems: Consider integrating heat recovery systems, such as those capturing heat from shower water. This practice not only improves energy efficiency but also aligns with the sustainability goals outlined in SIA 385/2:2025.

7. Document Heat Demand Distribution: Maintain accurate records of hourly distribution of heat demand. This documentation aids in analyzing usage trends and optimizing system performance, as per the recommendations in SIA 385/2:2025.

8. Establish Usage Conventions: Create clear usage conventions for hot water systems to promote efficient use. This practice supports compliance with hygiene standards and enhances overall system performance, as referenced in SIA 385/2:2025.
