Achieving reliable hot water performance in existing buildings: Aligning heat pump capability with system design

Facility managers facing ageing hot water systems, rising costs, or decarbonisation goals will gain clarity on how to select and design solutions that genuinely meet their building’s needs.

The session outlines how to assess heat pump capability—especially the ability to reach required storage temperatures despite limited performance transparency—and how system factors such as recirculation behaviour, pipe sizing, return temperature control, and ageing hydraulics shape efficiency.

Commissioning quality and ongoing parameter checks are highlighted as essential for achieving predictable performance and supporting business case outcomes.
