Experimental verification of the power required for thermal comfort in electrically heated clothing is presented. The clothing consists of a jumpsuit with embedded woven heating insets, controlled by a dedicated microprocessor system. The user is able to set heating power using a smartphone app. The experiments, conducted in a mobile freezing chamber, aimed at verification of the theoretical power (according to ISO 11079) required to maintain thermal comfort in ambient temperatures below 0 °C. The results are important as they impact the construction of heating insets, power electronics driving the heating insets, and the power rating of the battery.
