A household garden hose is provided with an integral electric power cord adapted to be plugged into a standard electrical wall outlet. The power cord extends along the full length of the hose and is adapted to provide electrical power to a power tool or other electrical appliance remote from the wall outlet. An electric resistance heating element is provided to heat fluid flowing through the hose and prevent freezing in cold weather. An outer jacket of insulation is provided over the hose to further resist freezing of liquid flowing through the hose.
