... but the ascaso uno pro is an independent boiler+thermoblock, which I assume is the machine in question.

Posted April 10, 2013 link

Yeah, was wondering of the boiler + thermoblock. Didnt know that only thermoblock machines existed...

fredk01 Said:

Are you sure it is a boiler plus steam thermoblock system?  I went to the Ascaso site and it was not at all clear what any of the Steel line of machines contained.  It would be good if it was as I think that, if properly implemented it is a definite step up from an SBDU machine.

Posted April 10, 2013 link

Yeah, their site is very unclear.

fredk01 Said:

Found the video.  Its the Ascaso Duo that is boiler + thermoblock.  I think the Uno is still a single boiler.

Posted April 10, 2013 link

New unos are apparently thermoblock only... Ive gotten a SBDU by accident (called my vendor), but that seems like an ok switch reading this thread, however nothing seems clearly better.
And then again, it takes something along no-time to heat up to steam. I just let the steamwand run for a moment and then nothing but steam.

Garry, my PERSONAL OPINION is that thermo block tech  has a long way to go before it is even the equal of a small boiler, as a steam system, it is better but for brewing not so much. YMMV

I think a lot of understanding/misunderstanding about machines stems from what I suffered from and probably to some degree Im sure probably still do. We buy a machine and it makes espresso and steams so we just think its doing what all machines do. I know to I posted a lot here about my Gaggia Classic and its capability. Looking at some of the things I said and my attitude towards those who had
used the same machine and moved on up the machine ladder,I think I was probably just misinformed. After two weeks of using the
La Nuova Era Cuadra I realize it makes real steam that is effortless and brews with such consistency. This kind of brings a humbleness to my prideful streak which is good. Makes me a little more receptive to those who have used more machines and spent more time making espresso. Yes IM sure there are machines that will run cricles around the La Nuova Era Cuadra Im sure of that. So do I think an inexspenive thermoblocked PID is out there ready to excel past the DB'rs and HX E61's no ...not really. I just hope I can be more humble and more teachable so I can leave it behind on this narrow journey so it doesnt become just so much useless bagage.

The Hx loop in an Hx machine is a form of 'Thermoblock'. One without active temperature control. (...unless you count the operator).  

Thermoblock technology has been used (and is used ever more today) for precise temperature control. A stable temperature grouphead and brew water to setpoint is not difficult at all.  For a home espresso machine though, built to pricepoint, that will take some very good engineering.  

I doubt any of the current machines qualify, but it is entirely possible to build one.

We're still waiting to find out.  Apparently it isn't quite so easy...

Liked that page a while back and followed their build. Quite interesting, especially if they manage to pull it off at it's price point. They've been doing test lately and people had quite high remarks for it vs machines that cost way more $$$$. They'll still have to overcome that "thermoblock stigma" that so many attach to low end/cheap machines. Be a cool unit for a single user or two at home.

At Bratdorf & Bronson roaster they mentioned this: "We were getting great complexity and repeatability, with the shots being better than a Nuovo Simonelli Oscar and even comparable to those you'd get from a La Marzocco Linea (wowza)!"
