Abstract
A steam ironing system (2) comprises a steam iron (10) and a boiler system (25) having a boiler (30) for generating steam, wherein the steam iron (10) and the boiler (30) are connected to each other through a steam hose (35). During operation of the boiler system (25), scale is formed in the boiler (30). For the purpose of removing the scale from the boiler (30), a rinsing process is performed on the boiler system (25) at regular intervals. During the rinsing process, a rinse valve (38) connected to a water outlet (37) positioned at a bottom of the boiler (30) is opened, and water is discharged from the boiler (30) to a rinse container (55). In the process, scale particles are carried along with the flow of water. Preferably, pressure is built up inside the boiler (30) prior to opening the rinse valve (38), so that the water is forcibly ejected from the boiler (30), whereby the effectiveness of the rinsing process is enhanced.
