In the middle of E61's boiler (hereinafter referred to as the outer boiler) is a pipe (hereinafter referred to as the inner pipe) which USES a pump to bring fresh cold water into the curved line inside.When the pump pushes fresh cold water through the pipe, the water will be surrounded by the external hot water from the boiler and heat, but peripheral tube package, therefore, fresh water and hot water boiler outside will not come into contact with, conduit road is done within the curve shape, the purpose is to make the cold water has enough time to contact outside the boiler and become just right for the hot water temperature of the brewed coffee.
Due to the circulation of hot water in the boiler, the temperature of each cup of coffee is also very close, whether it is a cup in an hour or a hundred cups in one go.In this way, not only the temperature difference can be reduced, but also the freshness of the water. The hot water in the outside boiler is only used to produce the steam that makes the milk foam, instead of making the coffee.
