Kessel Pro review
ReviewsA heat exchanger that behaves like a dual boiler until you push it.
Intro
Heat exchangers promise dual-boiler convenience at single-boiler prices. The Kessel Pro gets closer than most and then shows its hand.
Flushing
You need a cooling flush after steaming, and the amount depends on how long the machine idled. That is the part no spec sheet tells you.
| Spec | Value |
|---|---|
| Type | Heat exchanger |
| Boiler | 1.8 L |
| Warm-up | 14 min |
| Cooling flush | 40-120 ml |
Verdict
Good if you steam often but brew rarely. If you brew more than you steam, a dual boiler is less fuss.
