BC Cold Climate Heat Pump Field Study

In April 2019, twenty-six ductless mini split and central heat pump systems were monitored at twenty-four distinct single-family residential sites on Vancouver Island and in the interior of British Columbia in Climate Zones 4 and 5.

This study provides a better indication of the real-world efficiency and the resulting energy reduction and potential cost savings of air-source heat pump retrofits in existing homes in cold and moderate regions of British Columbia. The intended outcomes are to develop a clearer understanding of the performance of cold climate air-to-air heat pumps in Canadian climates; to evaluate design and installation considerations that may affect this performance; and, where possible, to identify design and installation best practices that positively affect the performance of heat pump systems. The information gathered in this study will inform the development of heat pump testing and rating procedures.
