Abstract
A steam generating system for use in a steam bath includes thermostatically controlled steam generating means for maintaining the steam bath environment at a desired temperature, means defining a water inlet path for conducting water from a water supply to the steam generating means, said inlet-defining means including an area of highly thermally-conductive material in thermal contact with the water. The thermostatically controlled steam generating means includes an electrically powered heating element, and a solid state switching device for controlling the amount of electricity flowing in the heating element. The solid state switching device is in thermal contact with said highly thermally-conductive material so that the switching device is cooled via heat transfer to the water flowing in the inlet path.
