How long does a defrost cycle last in the heating season for a heat pump?

5 minutes
10 minutes
15 minutes
20 minutes

The correct answer is: 10 minutes

A defrost cycle in a heat pump during the heating season is designed to remove frost buildup from the outdoor coil which can impair efficiency. The typical duration of a defrost cycle is around 10 minutes. This time frame strikes a balance between effectively melting frost and minimizing the time the system is not actively heating the indoors. If a defrost cycle were too short, it might not adequately clear the frost, while a longer duration could waste energy and reduce heating efficiency. Therefore, 10 minutes is commonly accepted as the standard duration for a defrost cycle in many heat pump systems during heating operations. Understanding this cycle is crucial for evaluating heat pump performance and ensuring optimal operation during winter months.
