Bathroom heater in winter and cold air machine in summer

There are four main reasons for tile cracking: first, there are problems with the quality of the tile itself, and its poor flexural strength and crack resistance lead to tile cracking; Second, the base treatment of the wall is unqualified, such as hollow cracking on the wall, waterproof brushing layer delamination of the wall, etc.; Third, the cement mortar ratio of ceramic tiles is unreasonable, the cement content is too high, and the expansion coefficient of cement mortar is too large, resulting in tile cracking; Fourth, there is no seam or too small when the tile is paved, the tile has thermal expansion and cold contraction, and the process of paving must be paved with seams, and it is very easy to cause the tile to crack if there is no seam.

1. When you take a bath, there will be water vapor on the mirror, which is the small water droplets in the air that are turned into when you are cold.

In the summer, if there are water stains, there is no evaporation, but in the winter, it will not work, and you can only rely on natural wind to dry. See what causes the watermark? If the watermark comes from downstairs, it is better to see if the waterproof layer of the upstairs bathroom is broken.

Because the temperature is low in winter, the water vapor during bathing condenses on the tiles and gets wet. In summer, the temperature is high and the water vapor does not condense.

This may be different from what is written on each brand of wind pestle, some are one switch, some are two switches, if it is a warm wind 1, there is a warm 11, I think it should be a warm wind 11 windy, try it to know.
