In a steam iron with a handle and fill opening to a water tank above an electrically heated soleplate and having a steam generator in the lower rear portion of the iron and soleplate steam ports, and a pump mounted in the handle and connected to the generator to rapdily force a volume of water to the generator for a surge of steam out the ports. To this general known combination, the invention provides an improvement of a bellows pump fixedly supported on an internal wall in the upper forward portion of the handle and completely external of the tank. Connected to one end of the pump is a double tubular conduit with the pump and conduit both being a flexible elastomer heat insulator with one conduit extending through the tank and terminating at and forming an exhaust outlet to the rear generator and the other conduit terminating adjacent the generator and in the tank as a suction inlet to the pump. One-way and position sensitive valves are disposed oppositely in the conduits and the entire double conduit extends in a slanted down direction from the forward pump to the rear generator whereby the iron may be operated in either a horizontal or vertical position to provide surge steam.
