It mainly concerns how the machine builds and maintains brew temperature during operation. A thermosiphon is a proven choice for businesses that want stable everyday capacity and simple operation. A dual boiler provides more separate control over brewing and steam, which is suitable when you want to fine-tune more. A multi-boiler system is at its strongest when demand is high and you want highly consistent performance from group to group during long shifts.

Buying is often suitable for businesses that already know what capacity they need and want to make a long-term investment in their equipment right away. Renting is a good alternative when you want to get started with a professional machine without the same initial capital investment, or when you want to match the equipment to a new establishment, seasonal operation, or changed service setup.

Base your decision on how many drinks you need to be able to prepare simultaneously during your busiest periods. Two groups are often enough for smaller cafés, restaurants, and service points with limited space. Three or four groups become relevant when several baristas work in parallel or when the flow is so high that queues would otherwise form.

It is most relevant for businesses that want to work actively with different beans, recipes, and flavor profiles. If the main goal is fast, repeatable service, there are other models in the range with a more straightforward workflow. If, on the other hand, you want to influence extraction more deliberately from coffee to coffee, this feature provides clear added value.
