Subject: HX vs Dual Boiler advice I got today... now I have a question
 

I really think I got some bad advice from one of the major retailers today, but just to be sure I am going to ask here in the forum.

I was told (by a salesperson at a major espresso machine retailer that you all would recognize) that I could not steam milk and make espresso at the same time on a HX machine. Now I have never owned a high quality espresso machine, but I think I can read and that is not what I thought I understood from reading in this forum and other places. Since I mostly drink lattes, I had made up my mind that I was going to buy a machine that wold do both when I laid down the cash.

Just to be clear, I can make espresso and steam milk at the same time on either a HX machine or a dual boiler machine... correct?

This is correct.  What I have heard is that when steaming and pulling a shot at the same time on smaller boilers, the in the HX line would be lower.  From what I've heard (a member who used scace to measure this) and in my own experience, this temp offset is negligable.  There's a lot of mass in the group, and the water inside the boiler (even on smaller boiler hx machines), that simply steaming isn't going to do much to the overall mass that controls the temp of the brewing line.

Nonsense. Of course you can. I imagine that there may be a few machines that are challenged to do this. It depends on the machine and it's thermal efficiency, recovery rates, and a bunch of other scientific stuff this art major probably doesn't know, but I use to do it all the time with my Vibiemme Domobar Super.

Time to find either:
A - a different machine
B - a different salesperson
C - a different reseller

Part 2 - Explain why. Full sentence answers. Spelling counts.

I understand the hesitancy to name the reseller, but what was the machine in question?

It's true of some machines.

You can't do it on mine. Brew switch disables steam, and vice-versa.

Fortunately, I don't find it a problem.

We were on the phone. Actually, we were not talking about a  particular machine. I just told the sales person that I wanted either a HX machine or a dual boiler machine because I wanted to be able to steam milk while making espresso or soon after. I had already made up my mind that the machine I would buy would probably be between $1100.00 and $1800.00 so not much of a salesperson. I didn't provide the salesperson with a budget though. I only told them the features that I wanted on the machine....

That list  was:
E61, HX or Dual boiler, ability to connect to water if I wanted and "maybe" a PID. And I also said I liked the chrome/stainless look of the bigger machines.

I don't know much about espresso machines, but I am pretty sure that list knocks you out of all of the machines below 1K so I don't know why they tried to talk me into a $629 machine that had none of the features I said I wanted. Again, not much of a salesperson and I am pretty sure they were distracted by something on their end... didn't seem like they was paying much attention to me.

I have read where other people here in the forum think a lot of the company, so probably just the wrong person to have answering the phone.

Not an HX vs DB thing, but I find it difficult to pull a shot and steam at the same time on a semi-automatic.  Ambitextrous multitaskers probably would not have problems.
That's part of the reason that I bought a Vivaldi.

Are you running a cafe? I've have never felt the need to steam and pull a shot at the same time at home. (And funny enough, I also own a Vivaldi).

Like texting and driving, don't take your eyes off what really matters. If you aren't watching your shot progress and cutting it off at the right time, you're probably making less than optimal espresso.

As long as the steam pressure is consistant and ready when your shot stops, that's more than enough.

No... personal use only. I just know I steam milk a couple of times a day and, while I agree I probably would not make coffee and steam milk at the same time, I think it would save time if I could start steaming milk as soon as the shot was done. I figure over a period of years, it would be worth the convenience. I never had the ability to steam and make coffee in the past with the machines I have owned and the time I have waited to steam milk is definitely not a good thing.

Brewing and steaming at the same time is all the fun.  I do it all the time.  Easier on the Vivaldi with it's programmable boutons but also fun on with a E61 brew head machine.

Just check how big the boiler is on the heat exchange. A 1.8 liter will do really well steaming.
