ABSTRACT:
A steam generator for domestic and industrial use, of the type which has a boiler (5) provided with a resistance heater element (17) and a steam and energy take-off unit (10) for supplying steam and electrical power to an external user item, such as a smoothing iron. At least a first solenoid valve (7) and a second solenoid valve (8) are connected between the boiler (5) and the take-off unit (10) to give rise to at least three separate levels of output steam rate. An electronic controller is coupled to the resistance heater element (17), steam and electrical power take-off unit (10), the power source and the solenoid valves (7,8) for automatically and proportionally exchanging electrical power applied to the resistance heater element (17) with electrical power applied to the external user item, thereby effectively exchanging the amount of steam available for use by, and the electrical power applied to, the external user item.
