A heat exchanger (HX) espresso machine uses one large steam boiler with a copper tube running through it. Fresh water flashes to brewing temperature in the tube, so you can brew and steam at the same time from a single boiler. HX machines are a popular step up from single boiler machines.Our heat exchanger range includes the Profitec Pro 400 and Pro 500 PID, the ECM Mechanika Slim, Mechanika V and VI Slim, Mechanika Max and Technika V Profi PID, the ECM Elektronika II Profi and the 969.Coffee Elba 3. Nearly all use the classic E61 group head; PID models let you fine-tune the boiler temperature instead of relying on a pressurestat.Compare them with dual boiler espresso machines if you want separate brew temperature control. Every order ships within the United States for a $70 flat rate and comes with 30-day returns.
