Overview
The Imons Dual Boiler Mini has generated significant buzz in the home espresso community as a Chinese-made dual boiler with an E61 group head at a price that dramatically undercuts established European manufacturers. The separate brew and steam boilers allow simultaneous espresso extraction and milk steaming without temperature compromise. PID control manages both boilers independently, and the pre-infusion system wets the coffee puck before full pressure application. The E61 thermosiphon group head provides the thermal stability that this classic design is renowned for. Build quality uses genuine stainless steel boilers and brass group head internals. While long-term reliability data is still accumulating, early adopters report performance comparable to machines costing two to three times the price.
The Imons Dual Boiler Mini comes equipped with PID temperature control for precise brewing, pre-infusion for even extraction. It features a single boiler boiler system made of stainless steel with a 250 ml capacity. The vibratory pump delivers 9.0 bars of pressure for optimal extraction.
Priced at $450, the Imons Dual Boiler Mini is designed for home baristas looking for quality without breaking the bank. The dual boiler design allows simultaneous brewing and steaming, making it ideal for milk-based drinks without any wait time.
In terms of build quality, the Imons Dual Boiler Mini is a substantial machine, weighing in at 12.0 kg, manufactured in China, drawing 1400W of power. With dimensions of 280 x 420 x 370 mm (W×D×H), make sure you have adequate counter space. The built-in water reservoir holds 1500 ml, making it easy to set up anywhere in your kitchen.

Our Verdict
The Imons Dual Boiler Mini is a single boiler machine, which means you'll need to switch between brewing and steaming temperatures for milk drinks. This sounds limiting, but many experienced baristas prefer single boilers for straight espresso — they're simpler, more reliable, and often extract beautifully. At under $500, it's a genuinely capable entry point into real espresso. Pair it with a good grinder (budget at least as much for the grinder as the machine) and you'll be surprised at what you can extract.
