Im Test von Gefriergeräten geben die Experten der Stiftung Warentest kleinen Einbaugefrierschränken den Vorzug vor massiven Gefriertruhen. Besonders energieeffizient sind aber selbst die Testsieger nicht.
In a 2025 test by Stiftung Warentest, small built-in freezers were preferred over large freezer cabinets due to their energy efficiency and faster freezing times. The test, conducted with European partners, evaluated 14 models available in Germany. Large freezers were deemed less energy-efficient or too slow, while small models froze test packages faster. According to the foundation, these small freezers incur approximately €1,000 in energy costs over 15 years. The full results and energy-saving tips are available on Stiftung Warentest's website.
