Is it really warm to put two buckets of water in the room in cold weather?

Water has a large specific heat capacity, so people who do this probably think that warm water can release more heat and prevent the temperature from dropping.

But the water will evaporate slowly, and in the process of evaporation, the water will absorb heat to complete the gasification process.

So put two buckets of water in the house, and it's good that the temperature hasn't been lowered by you. The correct way is to use a closed container (such as a warm water bag) to store water in the house.

If someone has to put two buckets of water at home in winter, the biggest function is not to keep warm, but to keep moisture.
