The core of the heating system of Delonghi coffee machines (such as EC680/EC860/EC9155 models) is a stainless steel boiler or a copper heat exchanger, which is suitable for a power range of 300W-1500W, a temperature control accuracy of ±1°C, and a thermal efficiency of ≥90%. The core of the heating element of Delonghi coffee machines lies in precise temperature control + efficient heat conduction. In view of the characteristics of its models, it is recommended to give priority to the combination of copper heat exchanger + titanium alloy electrode, and match it with an intelligent self-cleaning function to cope with hard water environments. Regular maintenance can ensure that the life of the equipment is extended to more than 8 years while maintaining the stability of coffee production.
