Abstract
A steam generator includes a pre-heat chamber configured to heat incoming water to a temperature less than the boiling point of water, where the pre-heat chamber is configured to heat the water such that if the water contains a calcium compound, the calcium compound is caused to take a particulate form. The steam generator also includes a filter assembly in fluid communication with the pre-heat chamber, the filter assembly including a removable particulate filter element, where the filter element is reusable and cleanable. The steam generator also includes a water pump in fluid communication with the filter assembly, and operative to cause water flow through the steam generator and a boiler in fluid communication with the water pump, where the water pump is configured to cause water to flow to the boiler, and where the boiler is configured to boil water such that steam is produced.
