  • How Do Espresso Machines Work? – Clive Coffee

    An additional water line is run from the pump, which then connects to a copper tube, or heat exchanger, that passes through the body of the boiler. The steaming water in the steam boiler heats the water in the heat exchanger without bringing it to a boil. In this style of system, the brew water will never come in direct contact with the boiler Get Price
