if a ergonal insulator is exposed to a sink of heat, then ergonal production will wreck the ergonal insulator become hot
if fuse does not occur then heat occurs. if enamel occurs then fire occurs. combusion_heating_element is heating_element. combusion_heating_element is not combustion_device. combusion_heating_element is combustion_device. combusion_heating_element is not heating_element. hot_tub has hot_water_in immersion_heater is heating_element. if fuse occurs then heat occurs. heat_pump is apparatus.
