Yes, putting hot or warm items directly into the freezer can increase its energy consumption and potentially shorten its lifespan.
When you place hot or warm items inside the freezer, it causes the internal temperature of the freezer to rise. The freezer then needs to work harder to bring the temperature back down to the desired level. The more the internal temperature fluctuates, the more energy the freezer consumes to maintain its set temperature. This increased energy consumption can lead to higher electricity bills.
Additionally, the increased workload on the freezer's compressor and other components can put extra stress on the appliance. Over time, this added strain can contribute to wear and tear, potentially shortening the lifespan of the freezer.
To maintain optimal energy efficiency and extend the lifespan of your freezer, it's best to let hot or warm items cool down to room temperature before placing them inside. You can do this by allowing the items to sit on the kitchen counter for a while or by using other cooling methods like placing them in the refrigerator for a short period before transferring them to the freezer. By doing so, you'll reduce the strain on the freezer and help it operate more efficiently.
