In what scenario would you typically avoid using a heat-drying system?

Using a heat-drying system in scenarios where it is hot and humid outside is typically avoided because high humidity reduces the effectiveness of the drying process. The goal of drying is to create conditions that facilitate the evaporation of moisture from materials. When both temperature and humidity are elevated, moisture content in the air can remain high, which hinders evaporation. This can lead to longer drying times and potentially promote mold growth, as moisture can get trapped in materials rather than being effectively removed.

In contrast, conditions where it is cold and dry outside can be conducive to drying, as the dry air can absorb moisture efficiently. A completely sealed affected area may also limit air exchange and impede drying, necessitating a different approach. Poor air quality can pose health risks but does not inherently contradict the objectives of heat drying; however, professionals must consider the environment's condition—including humidity—when deciding on a drying strategy.
