Abstract
A continuous-flow water distiller includes a housing having a removable heating vessel which receives water to be distilled A heater is immersed within the water in the vessel for producing steam. The housing includes an openable lid which, when closed, seals the heating vessel so that steam can be directed through an outlet into a condenser located in the housing. Raw water is supplied to the heating vessel through a heat exchanger to preheat the raw water by effectively utilizing thermal energy recovery to initiate cooling of the steam, and distillate is supplied through the condenser to enhance heat exchange.
