What is the maximum length allowed for domestic clothes dryer ducts?

The maximum length allowed for domestic clothes dryer ducts is determined by building codes and manufacturer guidelines to ensure proper ventilation and performance. A length of 35 feet is acceptable as it balances adequate airflow with the need to minimize the resistance created by bends and turns in the ductwork.

Longer duct lengths can impede the efficiency of the dryer, leading to longer drying times, increased energy consumption, and potentially causing overheating or fire hazards due to lint accumulation. The 35-foot guideline typically includes a reduction in allowable length for each bend in the duct, which ensures that ducts remain effective and safe.

This standard supports both the performance of the appliance and safety in the home, making it the optimal choice for the maximum allowable length of dryer ducts.
