The Rocket R58 is a fantastic dual-boiler espresso machine, featuring the high-quality commercial components and handcrafted build quality for which Rocket is known. A high-quality rotary pump draws water from the machine's internal water reservoir, or allows it to be plumbed directly from a water line. That's right - you can plumb this fantastic machine in. The Rocket R58 offers you dual boiler functionality and dual PID temperature control, in a classic chrome and stainless steel body. The machine comes standard with a 2.5-liter water reservoir, and a control switch that allows you to plumb the R58 directly into your kitchen's main water line. A pre-infusion system is a great feature that allows you to saturate the puck before reaching maximum pressure, ensuring a more balanced extraction. Price: 6500#
