Reversible air-to-air heat pumps emerged as the top-selling technology in Europe in 2024, with approximately 875,000 units sold. These systems, which provide both heating and cooling, gained traction particularly in warmer climates and are becoming more widespread as European summers grow hotter.
While the overall heat pump market faced a challenging year, performance varied by technology. Air-source systems continued to demonstrate the highest resilience due to their ease of installation, reduced noise, and affordability. These features support their ongoing role in Europe’s energy transition, especially in regions where cooling is increasingly in demand.
In contrast, sales of hot water and ground-source systems remained stable through 2023 but began to decline in 2024.
Reversible systems benefited from technical enhancements linked to tightening energy efficiency standards, which have improved system performance across the sector.
Tracking heat pump sales by technology is seen as a key indicator of market development and future growth opportunities, as policy and climate considerations continue to shape demand.
