Energy experts Maja Oldenburg and Ewald Gärber are highlighting efficient heating strategies to lower costs. Key methods include Stoßlüften, which involves opening windows fully for minutes, and bleeding radiators to remove trapped air that hinders warmth.
Stoßlüften can save 30 percent in energy compared to tilting windows, which cools walls and promotes mold. Gärber recommends this three to five times daily. Additionally, bleeding radiators can cut costs by 15 percent while ensuring optimal water pressure.
Simple habits like lowering room temperatures by one degree save six percent in energy. Keeping radiators unobstructed by furniture and closing shutters at night further reduces heat loss, allowing systems to operate efficiently with lower flow temperatures.
