Putting hot water directly into your fridge or freezer can potentially damage the appliance and is generally not recommended. Here's why:
Temperature shock: When you add hot water to a cold environment, such as the inside of a fridge or freezer, it creates a sudden temperature difference. This rapid change in temperature can cause the appliance's components, including the interior walls and shelves, to contract and expand quickly. Over time, this can lead to structural damage, like cracks or warping.
Overworking the compressor: Refrigerators and freezers rely on a compressor to cool the air inside. When you introduce hot water, the compressor will have to work harder and run for an extended period to bring the temperature back down to the desired level. This can strain the compressor and other cooling components, potentially leading to mechanical failure.
Uneven cooling: Adding hot water can disrupt the even distribution of cold air inside the appliance. This may result in uneven cooling, and certain areas of the fridge or freezer may not maintain the proper temperature, leading to food spoilage and waste.
Energy consumption: The increased workload on the compressor due to hot water can lead to higher energy consumption, resulting in increased electricity bills.
To avoid these potential issues, it's best to let hot water cool down to room temperature before placing it in the fridge or freezer. Alternatively, you can use an ice bath or let the hot water sit for a while in an open container to cool down more rapidly before transferring it to the appliance. This will help protect the integrity of the fridge or freezer and maintain its optimal performance.
