Air-source heat pumps (ASHPs) are all-electric building heating and cooling solutions that use electrical energy to move (not convert) thermal energy from a source to a sink, where the source is the outdoors in the winter and indoors in the summer. An ASHP thus pumps heat in the opposite direction from which it would normally move.

Scoring
These scores describe user experience with air source heat pumps in general, not differentiating among specific products. A 5-point rating (1-5) for each subscale was calculated as the mean of responses to all questions in the subscale--all asked with a 5-point response scale [Strongly disagree (1) to Strongly agree (5)]. Negatively framed questions were reverse-scored. Higher scores mean better user experience.
