Espresso machine features a dual stainless steel boiler heating system with electronic PID temperature control. The brew boiler extracts to within 1(DEG)F/1(DEG)C, while a separate steam boiler offers instant and powerful steam on demand. Shots are extracted at the right temperature, while milk is simultaneously steamed with the 3-hole tipped, 360 degree swivel steam wand. The Heat Exchanger and additional element in the group head ensure the entire system maintains a consistent temperature.
