This semi-commercial machine utilizes a heat exchanger system similar to those used on full-size commercial espresso machines. This allows it to deliver a consistently hot espresso, and simultaneous high pressure steam for cappuccino or latte.

And the three-way "solenoid" valve relieves pressure and sucks out the water in the group (brew head) when you've finished extracting your espresso. This means the portafilter (handle) can immediately be removed, re-filled with coffee and replaced to quickly brew your next single or double espresso.
