Which to choose
- Price tier — the headline difference. The Rocket Appartamento sits a tier up (prosumer) from the ECM Classika PID (mid-range) — you pay more for the spec advantages below. Tiers are price bands; confirm the live price at the retailer.
- Boiler — the deciding spec. The ECM Classika PID uses a single boiler and the Rocket Appartamento a heat exchanger (hx). One boiler heats for brewing OR steaming — you switch and wait between. The classic learner's architecture: cheapest path to real espresso, slowest workflow for milk drinks. A single boiler kept at steam temperature with a heat-exchanger tube drawing brew water through it — so you can pull a shot and steam milk at the same time. The prosumer sweet spot. This drives most of the milk-drink workflow and price difference between them.
- Temperature. The ECM Classika PID has PID temperature control (steadier shot-to-shot consistency); the Rocket Appartamento does not.
- Pre-infusion. Only the Rocket Appartamento pre-infuses (gentler shot start, better extraction on lighter roasts).
- Reach. The Appartamento also fits latte & cappuccino.
