Dual Boiler Coffee Machine

A dual boiler machine has one boiler used for brewing coffee and one for withdrawing steam and hot water. Both boilers are independent from one another and a PID, for example, can regulate the boiler temperature separately.

The boiler for brewing coffee is much smaller than the one used for steam and hot water. This means that the boiler contents is spent quicker and fresh water is used to prepare the espresso.

A dual boiler machine is more temperature stable than a machine with heat exchanger because of the two separate and individually temperature controlled boilers.

The Bella Barista team recommend Dual Boilers for home coffee drinkers that love drinking espresso on its own and milk based coffees (Cappuccino / Flat White / Latte ) etc.
