The fifth kind of this machine is also present which is often mistakenly called as an espresso machine. A fifth type is a machine driven by steam which produces strong coffee instead of authentic espresso.
There are also three subclasses for every type of espresso machine in the automatic and semi-automatic categories. Below is a detailed discussion about them.
Dual Use Single Boiler Machines
This is the commonest type which you can buy below 1,000 dollars. It has two thermostats and a boiler inside. The temperature of the water is controlled by one thermostat for brewing the coffee. The other one is set at a higher temperature with the purpose of producing steam for milk steaming. By just simply pressing or flipping a button, it transitions from the first thermostat into the other.
Heat Exchanger Single Boiler Machines
You can buy this machine at over 1,000 dollars price point. The single big boiler controls the temperature of the water at 240 F or higher which is ideal for producing steam. The water which is brewed goes to its group head through the coiled tube within the boiler. After this process, the water heats up making the temperature ideal for brewing. You can brew and steam at once on this machine.
Double Boiler Machines
This is a quite expensive machine and has two independent boilers (Thermo block or a boiler), where one maintains the water at a temperature ideal for brewing, while the other boiler maintains the water at temperature for steaming. You can brew and steam at once in his machine.
At first, it seems that those machines with double boilers are very desirable, whether automatic or semi-automatic. But in some areas like North America, it is a big problem of not having enough power for the standard 110 volts, 15 amperes wall socket for efficiently running two boilers that are European specs-based. This is gradually changing, and lots of companies make great strides to create efficient and powerful machines with double boilers. Lots of coffee makers reviews will also tell you about this and the things you have to look for the best coffee makers.
