Alicia Huertas, brand marketer at Robert Bosch Spain, notes that the low adoption rate is due to "a significant lack of knowledge about the benefits of these systems when choosing the technology, especially during renovations". For example, 60 per cent of Spaniards are still unaware that air-to-water heat pumps are a complete equipment for cooling, heating and hot water. Furthermore, according to Bosch, only one in ten Spaniards has upgraded their heating system to a more efficient and economical one, and more than 70 per cent of households are not familiar with the benefits of heat pumps.
