This article gives an overview of the study on using the air-to-water heat pump (A&WHP) for heating buildings in cold climate regions. The study was conducted in a relatively cold region (59°N), where the ambient temperature during the winter usually falls below-20°C. Despite the fact the COP of the air-to-water heat pump in the winter period was 2.5 on average and during the heating season of 2013/2014 the additional energy requirement was less than 3%.
