Low DHW Return Temperatures

Industry best practice guides, such as the London Heat Network Manual and CIBSE/ADE Heat Networks Code of Practice (CP1) recommend a primary return temperature of less than 25°C from domestic hot water production at full load.

The Evinox ModuSat XR has been designed to deliver return temperatures significantly below this across a wide range of primary system operating conditions.

By incorporating ultra-high efficiency domestic hot water plate heat exchangers with improved volumetrics which encourage turbulent flow, designers are given the opportunity to focus on the energy efficiency performance of HIU systems, while continuing to maintain impressive full load hot water capacity and flow rates.

This contributes to excellent annual Volume Weighted Return Temperatures and system operating efficiency.
