Heat pump dryers use up to 70% less energy than condenser dryers and are more in demand than ever in times of rising electricity prices. But there is also a negative aspect: In the manufacturing process, climate-damaging gases are often used as coolants. Gorenje has switched production, uses propane (R290) as a natural refrigerant for the new generation of tumble dryers and has thus achieved CO2 savings of 99.99%.
