Customer called about a power loss to the back left bedroom and bathroom circuit. Found tripped breaker (bottom right). Breaker was difficult to reset due to age. Reset breaker and restored power to the circuit. Informed customer that the small space heater that was being used was drawing 12.5 amps on a 15 amp circuit. Customer also stated that they had an electric fireplace on the same circuit but has since sold it. Customer had an extension cord plugged in to the living room outlet. Outlet was hot to the touch. Recommended replacing the original panel as well as replacing devices
