Abstract
The outcome from this Annex activity clearly identifies that poorly designed, installed, and/or maintained heat pumps operate inefficiently and waste considerable energy compared to their “as-designed” potential. Additionally, it is clear that small faults for a given field-observed practice are significant, that some attribute deviations (in various equipment applications and geographical locations) have a larger impact than others, and that multiple faults or deviations have a cumulative impact on heat pump performance.
