Heat exchanger vs dual boiler

Sure, espresso is a great drink by itself, but it is the lattes and the cappuccinos that really conquered the world. There are many different parts to espresso machines that contribute to the amount and quality of steam they can produce. The two best espresso machine types for steam output are heat-exchangers and dual boilers.

A double boiler has two boilers on a single machine. Each boiler for a specific function. One is the brew boiler, set at a lower temperature. The other is a steam boiler set at a much higher temperature. By keeping them separate, the user will have full control over the brew temperature and should be more consistent in the extraction.

Post Reply Search Advanced search. Post reply Quote 1 : Post by BaristaMcBob » November 18th, , am I understand how the two systems are different, from a design perspective. Double Boiler Espresso Machines covers the basics. Upside is much easier workflow and better consistency. If you can swing it cost-wise, DB is a no-brainer in my book having owned both. Machines like Lelit's MaraX, somewhat blur the line in terms of workflow and consistency, but it is a cost compromise, so I come back to to DB if you can. They said the main drawback to HX, according to the video, is the need to pre-flush. My brew water is always the right temp. I don't get a blast of steam if I pre-flush as the machine in the video did. My other machine, ECM with an E61, doesn't release a "dragon" either. So maybe that's an issue with some HX machines and not others? I wish they had demonstrated steaming power. Very informative video otherwise.

Homage to the tradition with a second look. Dual Boiler Buyer Ideal for someone that likes to do milk-based drinks but also does a lot of espresso and cares about shot consistency with the ability to adjust brew temperatures.

Home espresso machines may produce the same delicious beverages, but the mechanics involved can vary from one machine to next.

As the name suggests — dual boiler espresso machines have two boilers, whereas a heat exchanger machine only has one. This is the most obvious difference between the two types of machines, yet both can produce the very high temperatures needed for steam and the below boiling temperatures needed for quality espresso. A heat exchanger espresso machine like the Appartamento from Rocket keeps the water in the boiler at temperatures high enough to create steam, roughly — F. The steam boiler is half filled with water and has a heat exchange tube inside where water from the reservoir is fed into and flash heated before channeling it into the group to make the coffee. The steam valve above the water and heat exchange tube is where steam is pulled from to create steam and make your milk-based drinks.

Heat exchange and dual boiler espresso machines are separated by how they handle different temperatures for pulling espresso and steaming milk.

As well as which boiler type is best for your needs. If you find the content in this video helpful, please like and comment so we know if we should make more videos like it. The machine warms up, stabilizing temperature in the boiler and the group head. When shot is pulled, water is pulled directly from the boiler. Temperature remains stable how stable depends on the machine. After shot is completed, the machine can be switched to steaming mode. Before steaming can take place, the boiler temperature has to increase to provide enough steam pressure for frothing milk. At about degrees, the machine is ready for steaming.

Vibration pumps are most common. The water temperature throughout the extraction should maintain around 90 degrees with little deviation from its set temperature. Why, though? By accessing this site, you agree to the site's terms of service. They are known to express a broader spectrum of flavours and tame the harsher astringents in espresso.

In the realm of coffee craftsmanship, espresso machines reign supreme , transforming humble coffee beans into liquid gold.

Oddly enough, the on-line world of hobbyist espresso and barista competitions is what changed this. However, the temperature could easily fluctuate during the extraction if designed too small. All three machines run the steam boiler at near 2 bar of steam pressure, in comparison to other dual boiler machines running at about 1. Manufacturers have gotten better about tuning "no fuss" heat exchangers for home-friendly usage i. For machine buyers -- look closely at the actual specs, look for expert user reports, and put you buzzword cheat sheet back in the drawer. The higher the heat or temperature, the more energy it brings to the coffee during extraction. Specialty grade, found by the founder of CSC certification the most demanding standard for coffee. It doesn't take long to heat up and get to pressure. Even a simple maintenance process like descaling is much more complicated on the double boiler requiring professional assistance. It's definitely one of my favorite additions to my coffee-making collection, and I'll probably love it even more when I finally do pull that perfect shot.
