A dual boiler machine has one boiler for brewing and a separate boiler for steaming. That lets you pull a shot and steam milk at the same time, with steady temperature on both sides. It's the setup most serious home baristas and busy cafes reach for.
Here's the short version on dual boiler vs. heat exchanger. A heat exchanger warms brew water by passing it through the steam boiler, so the two are tied together. A true dual boiler keeps them separate, which gives you more consistent shots when you're pulling drinks back to back.
