Which to choose
- Price tier — the headline difference. The Bezzera BZ10 sits a tier up (prosumer) from the Breville Dual Boiler (BES920) (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 Bezzera BZ10 uses a heat exchanger (hx) and the Breville Dual Boiler (BES920) a dual boiler. 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. Separate boilers for brew and steam, each independently temperature-controlled. The most stable, most flexible architecture — and the most expensive. This drives most of the milk-drink workflow and price difference between them.
- Temperature. The Breville Dual Boiler (BES920) has PID temperature control (steadier shot-to-shot consistency); the Bezzera BZ10 does not.
- Portafilter — accessories don't transfer. The Bezzera BZ10 takes a 58mm portafilter and the Breville Dual Boiler (BES920) a 54mm, so tampers, bottomless portafilters and baskets bought for one won't fit the other.
Which one should you buy?
- Pick the Breville Dual Boiler (BES920) if you want PID temperature control for shot-to-shot consistency; or if you want the lower price band (mid-range rather than prosumer).

Common questions
Do portafilters and baskets fit both the Bezzera BZ10 and the Breville Dual Boiler (BES920)?
No. The Bezzera BZ10 takes a 58mm portafilter and the Breville Dual Boiler (BES920) a 54mm one, so tampers, bottomless portafilters and baskets bought for one will not fit the other. Budget for accessories separately once you pick.
Is the Bezzera BZ10 worth the step up from the Breville Dual Boiler (BES920)?
Stepping up from mid-range to prosumer buys you a heat exchanger (hx) instead of a dual boiler. Worth it if you brew milk drinks daily or chase consistency; not if you mostly pull straight espresso. Tiers are price bands — confirm the live price at the retailer before deciding.
